Epidemiology of human visceral leishmaniasis in Taounate, a northern province of Morocco.

We report the preliminary results of an epidemiological survey carried out in the locality of Ouled Hcein, province of Taounate (North Morocco) around one visceral leishmaniasis infant case. The strain isolated from the child was characterized by three methods as Leishmania infantum and its isoenzyme pattern was indistinguishable from zymodeme MON-1. The human survey in the locality of origin of the index case did not show any additional case and the serology was negative for the whole people sampled. The canine survey showed that the highest seroprevalence of the canine disease was found in the locality of Ouled Hcein (27.1%) when compared to 4 surrounding localities. The entomological survey showed that amongst the demonstrated L. infantum vectors around the Mediterranean Basin, Phlebotomus longicuspis was the predominant species. Furthermore, the survey led to the identification of one female of P. ariasi naturally infected with L. infantum, so this species should be at least one of the vectors of this parasite in this area. Thus, this study confirms that the transmission cycle of L. infantum in North Morocco is similar to the cycle found in the remaining Mediterranean area.

Mutational analysis of the Myocilin gene in patients with primary open-angle glaucoma in Morocco.

PURPOSE: To investigate the Myocilin (MYOC) gene for mutations and polymorphisms in patients with primary open-angle glaucoma (POAG) in Morocco. METHODS: Fifty-seven patients with severe POAG, who suffered from complete or almost complete visual field loss, were included in the study. The MYOC coding region, including exon I, exon II, and the coding part of exon III, were screened for sequence alteration using denaturing high-performance liquid chromatography (DHPLC). Variant amplicons were sequenced bidirectionally. The control group consisted of 60 subjects from the general population. RESULTS: One disease-causing mutation, T377M, was observed in one POAG patient. In addition, 10 polymorphisms, namely P13P, R76K, R82H, G122G, T135I, L159L (often associated with P13P), T285T, T325T, Y347Y, and E396E, were detected in patients or in controls. The Q368X mutation that has been documented in Caucasian POAG patients was absent. CONCLUSIONS: MYOC is an infrequent genetic cause of severe POAG in Morocco. The absence of the POAG-associated Q368X mutation and the presence of particular polymorphisms, including P13P + L159L and T325T, could be specific features of the MYOC sequence in African populations.

The effect of remittances on emigration intentions in Egypt, Morocco, and Turkey.

Are remittances determined by altruism or enlightened self-interest, and do they trigger additional migration? In this paper these two questions are examined empirically in relation to data from Egypt, Turkey, and Morocco for households with family members living abroad. It is shown, firstly, that one cannot argue exclusively either for altruism or self-interest as motives, since for each country the data tell a different story and both motives can be identified as driving forces behind remittance behaviour. The general conclusion of this study is that the family ties and the net earnings potential of migrants have stronger effects on the flow of remittances than the net earnings potential of the households in the country of origin. Secondly, because the receipt of remittances has a positive effect on the emigration intentions of household members still living in the country of origin, the receipt of remittances may contribute to new flows of migration, particularly in the case of Morocco.

Dermatoglyphic characterization of Berbers from Morocco: qualitative and quantitative digital and palm data.

BACKGROUND: The demographic impact of the Arabization in the Berber genetic background has been extensively studied by means of different classical and DNA genetic markers. Information from other biological traits as dermatoglyphics could be of interest in order to gain an insight into the relationship between these two North African groups. AIM: The Moroccan Berber population is characterized by means of digital and palm dermatoglyphics to determine the degree of genetic affinities among Berber and other Mediterraneans, especially the Moroccan Arab-speakers. SUBJECTS AND METHODS: Finger patterns, pattern intensity, finger total ridge counts, pattern frequencies in the five configuration areas of the palm, mainline D terminations, and a-b ridge count were analysed in a sample of 120 males and 103 females of Moyen Atlas (Morocco). RESULTS: Bilateral asymmetry was more pronounced than sexual differences in the overall distribution of the analysed traits. Our two series (males and females) exhibit high values of total ridge count (TRC) and mainline D terminations in comparison with other Mediterranean series. Several pattern frequencies in fingers and palm areas also differentiate the Berbers of Moyen Atlas from North Africans. CONCLUSION: The picture obtained by principal components based on qualitative digital and palm data revealed that Berber males were within the variation range of North African groups while Berber females clustered with some Iberian samples. The population pattern obtained in a bivariate plot of quantitative finger data showed the Berbers (males and females) as the most differentiated population in the Mediterranean context. Dermatoglyphic data failed to indicate any particular proximity between Berbers and Arab-speakers from Morocco.

Classical polymorphisms in Berbers from Moyen Atlas (Morocco): genetics, geography, and historical evidence in the Mediterranean peoples.

BACKGROUND: Mediterranean population relationships have recently been reviewed through the analysis of classical and DNA markers. The differentiation between Berbers and Arabic-speakers to the south, and the genetic impact of the seven centuries of Muslim domination in the Iberian Peninsula have been among the most interesting questions posed in these studies. AIM: The present study seeks to assess the degree of genetic affinity between the two main population groups of Morocco: Berbers and Arabic-speakers. Data from the Berber study population were also compared with published information on 20 circum-Mediterranean groups. SUBJECTS AND METHODS: A Berber sample of 140 individuals from Moyen Atlas (Morocco) has been characterized using 15 classical markers (ABO, Duffy, MNSs, Rh, ACPl, AKl, ESD, GLOI, 6-PGD, PGMl, GC, HP, PI, PLG and TF). RESULTS: Allele frequencies in the Berbers fit well into the general southern Mediterranean ranges, albeit with some peculiarities, such as the high FY*A, ACPl*C, and PI*S values. The general pattern of relationships among Mediterranean peoples tested by genetic variance analysis was compatible with a north-south geographical differentiation. Spatial auto-correlation analysis in the different geographical regions of the Mediterranean reveals that the highest degree of association between allele frequencies and geographical distances corresponds to the western (41% of significant correlograms) and northern Mediterranean populations (33%). When only southern Mediterranean groups were considered, the degree of geographical structure considerably decreases (11% of significant correlograms). CONCLUSIONS: The different loci studied revealed close similarity between the Berbers and other north African groups, mainly with Moroccan Arabic-speakers, which is in accord with the hypothesis that the current Moroccan population has a strong Berber background. Differences in the spatial pattern of allele frequencies also are compatible with specific population histories in distinct Mediterranean areas, rather than general population movements across the whole region.

Silent crises in the COVID-19 pandemic shadow: a six-year medico-legal review of non-lethal intimate partner violence in Morocco.

Intimate partner violence (IPV) is a major global public health concern and one of the most prevalent forms of gender-based violence, with significant consequences. This study analyzes non-lethal IPV cases reported to a medico-legal unit of Casablanca between 2018 and 2023. Data from 4,784 female victims were reviewed, focusing on socio-demographics, violence types, perpetrator relationships, and judicial involvement across the pre-COVID, peak COVID-19, and post-COVID periods. Married women represented 59.2% of victims. Physical violence predominated (83.1%), while sexual violence was underreported (14.7%). The year 2020 marked a sharp increase in reported non-lethal IPV cases (n = 1,005), correlating with pandemic confinement. Among married women, judicial requisition (legal request for forensic examination) and medico-legal certification (medical documentation for judicial use) rates were high (81.5% and 81.0%, respectively). Post-pandemic years declined moderately but remained above pre-COVID levels. International comparison confirmed a global rise in IPV during COVID-19, with Morocco displaying comparatively higher rates of medico-legal documentation and judicial involvement. IPV in Morocco is entrenched and intensified by COVID-19. While the medico-legal system is robust in documentation, the system must evolve by integrating systematic psychological assessment into medico-legal evaluations, standardizing certification and referral protocols, and strengthening coordination between medico-legal, health, and social support services to improve victim protection.

First isolation of Borrelia burgdorferi sensu lato from Ixodes ricinus ticks in Morocco.

To determine the infection rate of Ixodes ricinus (I. ricinus) ticks with Borrelia burgdorferi sensu lato (B. burgdorferi sl) and to assess the frequency of the individual Borrelia species in this tick species, a total of 295 I. ricinus were collected in Taza region (Northeast of Morocco), from January to June 2002. The presence of B. burgdorferi sl was determined by direct fluorescence antibody assay (DFA) and by PCR after culture. B. burgdorferi sl isolates were identified at the species level by restriction fragment length polymorphism analysis of amplified products. The mean rate of I. ricinus infection with B. burgdorferi sl was 47.8%. Isolation attempts in BSK II medium resulted in 26 pure isolates. However, PCR performed on culture medium allowed to identify 82 Borrelia DNAs. B. lusitaniae has been identified from 76 out of 82 infected I. ricinus ticks (92.7%). Three ticks were infected by B. burgdorferi ss, and three other ticks were infected by B. garinii. This is the first report of the presence of B. burgdorferi sl in Morocco and more specifically of B. burgdorferi ss in North Africa.

Prevalence of the main cardiovascular risk factors in Morocco: results of a National Survey, 2000.

OBJECTIVE: The aim of this study was to determine the prevalence of the main cardiovascular risk factors in Morocco and their distribution according to age, sex and residential area. METHODS: The study was conducted during the year 2000 on a Moroccan representative sample aged 20 years and over, considering the population distribution between urban and rural areas. The crude results were weighted according to the Moroccan population distribution by age and sex. In order to allow comparison with data from other countries, means and prevalence were standardized according to world population distribution by age. RESULTS: The participation rate was 90.1%. The prevalence of hypertension was 33.6% (30.2% for men and 37.0% for women). The means of systolic and diastolic blood pressure were 129.8 and 76.0 mmHg, respectively. The prevalence of diabetes was 6.6% and was similar for males and females. The prevalence of hypercholesterolaemia was 29.0%, and was higher in females. The means and prevalence of diabetes and hypercholesterolaemia were higher in urban areas. The prevalence of hypertension, diabetes and hypercholesterolaemia increased with age. The prevalence of obesity was markedly higher in females and in urban areas. The average body mass index was 23.8 and 25.6 kg/m2 in males and females, respectively. Thirty-four per cent of men smoked cigarettes, but women rarely smoked cigarettes (0.6%). CONCLUSIONS: The prevalence of cardiovascular risk factors was high in Morocco and it is necessary to increase action against the cardiovascular diseases and their risk factors.

Technology and neurosurgery in developing countries: experience and present situation in Morocco.

OBJECTIVE: The high cost of technology is considered to be the determining factor slowing the expansion of modern neurosurgery in many developing countries. The literature dedicated to this topic rarely proposes internal solutions whereby affected countries can overcome this economic impediment. Certain articles cite inevitable obstacles, and the neurosurgeons of these countries can become disheartened when these articles conclude with calls for foreign help as the only approach to the development of neurosurgery. METHODS: Morocco is presented as an example of a developing country in which neurosurgery has become well established in the past 30 years, using a program based on four guidelines, as follows: 1) encouraging the local training of young neurosurgeons, 2) organizing and promoting neurosurgery, 3) integrating the development of neurosurgery into the health care pyramid system, and 4) stimulating research on local pathological conditions. RESULTS: Because of the internal planning efforts stimulated by the first national neurosurgeons, Morocco has progressed from 2 underequipped neurosurgical services and 5 neurosurgeons in 1968 to 12 well-equipped services and 80 neurosurgeons in 1998. The main benefits of this progress are discussed. CONCLUSION: Neurosurgery in developing countries can be promoted if the first working neurosurgeons take up their responsibilities as pioneers. This role requires that they initiate the training of young neurosurgeons as soon as possible and that they find in the local conditions the necessary factors to promote neurosurgery and to integrate it into the health care development of their country.

Human leukocyte antigen-A, -B, and -Cw polymorphism in a Berber population from North Morocco using sequence-based typing.

Class I human leukocyte antigen (HLA) polymorphism was examined in a Berber population from North Morocco, named Metalsa (ME). All data were obtained at high-resolution level, using sequence-based typing. The most frequent alleles were: HLA-A*0201 and A*0101; HLA-B*44 (B*4403 and B*4402); B*0801 and the B*50 allele group (B*5001 and B*5002); HLA-Cw*0602; and Cw*07 group (Cw*070101, Cw*070102, Cw*0702, Cw*0704, and Cw*0706), and Cw*040101. The novel HLA-B*570302 allele was identified. It differs at position 486 and position 855 from B*570301, resulting in synonymous Thr and Val. The analysis also evidenced some alleles common in Africans (A*3402, A*6802, A*7401, B*1503, B*4102, B*4202, B*7801, B*5802, Cw*1701, and Cw*1703) and some uncommon alleles (A*3004, B*2702, B*2703, B*5001,02, B*3503, and Cw*0706). The predominant HLA-A-Cw-B-DRB1-extended haplotypes in ME population were A*0101-Cw*0501-B*4402-DRB1*0402, A*240201-Cw*0701-B*0801-DRB1*030101, A*2301-Cw*040101-B*4403-DRB1*040501, A*0201-Cw*040101-B*4403-DRB1*1302, and A*3002-Cw*0602-B*5002-DRB1*0406. This study demonstrates a strong relatedness of ME to other Moroccan and North African populations, some characteristics of sub-Saharan Africans and evidenced the influence of various immigrations during centuries. Nevertheless, this study highlights some unique genetic traits of the ME population compared to other ethnic groups within Morocco, which could be of great interest for clinical aims, transplantation, and diseases.

Paratuberculosis in sheep flocks in Morocco: a serological, microscopical and cultural survey.

In an attempt to estimate the importance of Johne's disease in sheep in Morocco, a diagnostic survey was made in three flocks suspected of being infected with Mycobacterium paratuberculosis. Blood and faeces samples collected randomly from 188 adult sheep were investigated using direct microscopy of fecal smears, fecal culture and the serum complement fixation test (CFT). Microscopical examination of faeces revealed acid-fast bacteria in 67 (35.6%) samples. However, Ziehl-Neelsen staining lacks specificity and furthermore, acid-fast bacteria could only be demonstrated in 34 (60%) animals found to be culturally positive. Fecal culture succeeded in the isolation of mycobactin dependent strains of M. paratuberculosis in 56 (29.8%) of the sheep examined, with three strains growing in yellow-pigmented colonies. The CFT was regarded as positive (titres of 1:10 and higher) in 55 (29.2%) sera of animals, demonstrating a sensitivity of 48.2% and a specificity of 74.5% in relation to fecal culture From the results, it can be concluded that the combination of CFT and fecal culture might be a practical and useful procedure for detecting infected sheep within flocks and for controlling Johne's disease. This study supports the suspicion that paratuberculosis may constitute a serious problem in Morocco, particularly in sheep flocks involved in cross-breeding programmes.

Pharyngeal carriage of serogroup W135 Neisseria meningitidis in Hajjees and their family contacts in Morocco, Oman and Sudan.

In 2000 the global outbreak that began in Saudi Arabia was caused by a W135:2a:P1.5,2 strain of Neisseria meningitidis belonging to the ET-37 complex and to ST-11. There was concern that introduction of this epidemic clone (EC) might lead to a wave of outbreaks in the African meningitis belt. The WHO therefore initiated studies of meningococcal carriage among pilgrims and their family contacts in Morocco, Oman and Sudan, 3 to 12 months after the Hajj 2000. In Morocco, 1186 persons were swabbed 3 times. Ninety-five meningococcal strains were isolated from 2.7% of the specimens. Pulsed-field gel electrophoresis showed that 32 (33.6%) were identical with the EC. In Sudan, 5 strains identical with the EC were obtained after sampling 285 persons. In Oman, among 18 meningococcal strains isolated from 399 subjects, 11 (61.1%) belonged to the EC. The important pharyngeal carriage of W135 (EC) and its role in the 2001-2002 outbreaks in Burkina Faso argues for the necessity of reinforcing surveillance, and adapting and planning responses in Africa and the Middle East using the most appropriate vaccine.

Seroepidemiological study of herpes simplex virus types 1 and 2 in Brazil, Estonia, India, Morocco, and Sri Lanka.

BACKGROUND: The association between herpes simplex virus type 2 (HSV-2) and human immunodeficiency virus (HIV) and the development of HSV vaccines have increased interest in the study of HSV epidemiology. OBJECTIVES: To estimate the age and sex specific seroprevalence of HSV-1 and HSV-2 infections in selected populations in Brazil, Estonia, India, Morocco, and Sri Lanka. METHODS: Serum samples were collected from various populations including children, antenatal clinic attenders, blood donors, hospital inpatients, and HIV sentinel surveillance groups. STD clinic attenders were enrolled in Sri Lanka, male military personnel in Morocco. Sera were tested using a common algorithm by type specific HSV-1 and HSV-2 antibody assay. RESULTS: 13,986 samples were tested, 45.0% from adult females, 32.7% from adult males, and 22.3% from children. The prevalence of HSV-1 varied by site ranging from 78.5%-93.6% in adult males and from 75.5%-97.8% in adult females. In all countries HSV-1 seroprevalence increased significantly with age (p<0.001) in both men and women. The prevalence of HSV-2 infection varied between sites. Brazil had the highest age specific rates of infection for both men and women, followed by Sri Lanka for men and Estonia for women, the lowest rates being found in Estonia for men and India for women. In all countries, HSV-2 seroprevalence increased significantly with age (p<0.01) and adult females had higher rates of infection than adult males by age of infection. CONCLUSIONS: HSV-1 and HSV-2 seroprevalence was consistently higher in women than men, particularly for HSV-2. Population based data on HSV-1 and HSV-2 will be useful for designing potential HSV-2 vaccination strategies and for focusing prevention efforts for HSV-1 and HSV-2 infection.

HIV epidemiology in Morocco: a nine-year survey (1991-1999).

The first case of HIV/AIDS in Morocco was notified in 1986. The Moroccan Ministry of Health has set up a system of management of HIV/AIDS cases and surveillance of the epidemic. Between 1991 and 1999, we studied 12,981 sera from patients in different Moroccan regions, who attended with high risk and/or symptoms of HIV/AIDS. The overall prevalence of positive HIV serology was 5.04% (4.67-5.44%). This rate was higher compared to blood donors which is 0.02%. From 1993 to 1998, the prevalence was around 4-5% (2.73-6.26%) then increased to 8.06% (6.89-9.36%) in 1999. Retrospective analysis of available epidemiological data have shown that the highest rate was observed in the South of Morocco with 12.23% (11.10-13.44%). Of the HIV positive cases, 72.22% of seropositives were infected heterosexually, 11.11% by intravenous drugs use, 7.41% by homosexuality, 4.63% by bisexuality and 4.63% and 0.62% by vertical transmission. The median age of infected persons was 33.3 years. Among documented HIV-positive individuals, 53.74% were aged 30-39 years, 21.43% were 20-29 years and 17.69% were 40 years or more. In this study, among HIV-positive patients 42.17% have loss of weight with fever and diarrhoea represent and 35.54% have loss of weight with fever, diarrhoea and opportunistic infections. The present work shows that the HIV infection increased significantly in 1999. Effective measures to control this trend should be implemented soon before the situation worsens.

Natural and induced ovulation rate in prolific and non-prolific breeds of sheep in Ireland, Morocco and New Zealand.

Ovulation rate, in mixed-age groups of prolific and non-prolific ewe breed types, after administration of a range of doses of PMSG (0, 375, 750 and 1500 i.u.) during the follicular phase of the oestrous cycle, were compared in Ireland, Morocco and New Zealand. The ewes in Ireland and Morocco were from the Finnish Landrace and Galway, and D'Man and Timhadite breeds, respectively. In New Zealand Booroola Merino x Romney ewes which had been previously identified as heterozygous carriers (F+) of the Booroola high fecundity gene and purebred Romneys were used to represent the prolific and non-prolific genotypes respectively; in addition a group of Booroola Merino x Romney non-carriers (++) of the major gene were also included for comparison. Ovulation rate at the oestrus which preceded stimulation with PMSG was also measured in all animals. In all 3 locations the ewes of the prolific genotype had a greater ovulation rate after PMSG stimulation than did the non-prolific controls. However, this association between prolificacy and response to PMSG was removed when ovulation rate after PMSG was transformed by dividing by the ovulation rate observed before PMSG administration. Despite the differences in the genetic basis of their high prolificacy the pattern of response to PMSG over the range of dosages used was similar in Finnish Landrace, D'Man and Booroola Merino x Romney (F+) ewes and all breeds had means of about 10 ovulations in response to 1500 i.u. PMSG. Amongst the non-prolific breeds, the Timhadite was the most responsive to PMSG although it had the lowest natural ovulation rate.(ABSTRACT TRUNCATED AT 250 WORDS)

The management of familial hypercholesterolaemia in Morocco.

Familial hypercholesterolaemia (FH) is an autosomal dominant disorder characterized by high levels of low-density lipoprotein cholesterol (LDL-C) as a result of mutations that impair their removal from plasma.The clinical consequence is a high risk of premature cardiovascular disease. Because of the extreme risk of mortality and morbidity, diagnosis, recruitment and management of FH patients must be one of the priorities of public health. In Morocco, specialized consultation for dyslipidaemia and strategy for management of this cardiovascular major risk factor does not exist, making FH identification and management difficult. In this review, we present the first FH state of the art in our country through a sample of 66 subjects. By this analysis, we have tried to elucidate some points that impede the identification and recruitment of heterozygous FH and the management of both heterozygous and homozygous FH in Morocco. Also, we have attempted to propose some strategies for an adequate management of FH in our country, taking into account the local specifications.

Kif in Morocco.

Chronic cannabis intoxication of a significant fraction of the male population still prevails in Morocco. The preparation used (kif) is a powder made from the dried flower of the female plant. It contains 2 to 3% THC and is smoked mixed with tobacco (1/3 of the mixture). Cultivation of kif is tolerated in an area of 60 square miles in the high Rif mountain of Northern Morocco, where it constitutes the main cash crop of the local farmers. A significant percentage (50%?) of the men in the area also consume kif regularly. This cultivation is spreading to neighboring areas. Moroccan health authorities claim that cannabis intoxication represents a major health hazard. There exist little data correlating chronic usage of kif with pathological states in these areas of large production and consumption. This dearth of information due to lack of local medical personnel could be alleviated by a combined medical and ethnological study.

[Measuring levels of professionally-related stress in taxi drivers in Fes, Morocco].

Professional stress is a harmful physical and emotional reaction that can occur when tension exists between the requirements imposed on a person and the level of control that person may, or may not, have on the fulfillment of these requirements (essentially tension between what one is expected to achieve and what one can realistically achieve). At present, traffic accidents are considered to be a major social problem in Morocco. The authors aim to describe stress levels in taxi drivers and to study potential associated factors, in particular the risk of having an accident while driving. A questionnaire was administered in a cross sectional survey to a sample of 338 taxi drivers working in the city of Fes, Morocco. Stress was evaluated by using a standardized scale developed by the French National Institute of Research and Safety (INRS). It allows for the intensity of stress to be quantified according to a set of seven scores. According to the INRS scale, 46.3% of the taxi drivers could be considered as stressed. Moodiness and blood pressure problems were specifically identified as indicators of stress in this population. These results should incite interest in developing prevention measures in order to reduce or eliminate sources of stress at work in order to decrease the number of traffic accidents related to stress, and hence to improve the taxi drivers' working conditions.
