Studies of taeniasis in Taiwan. XII. Prevalence of taeniasis among Atayal aborigines in Wufeng District, Hsinchu County, northwest Taiwan.

In order to determine the prevalence of taeniasis in the Wufeng District of Hsinchu County, 341 school children from 2 primary schools and 748 Atayal aborigines from 4 villages were examined with a scotch tape perianal swab and by questionnaire and demonstration of proglottides. The infection rates of taeniasis and enterobiasis among the school children were 1% and 8%, respectively. The overall infection rate of taeniasis among the Atayal aborigines was 6%, and 189 previously treated and cured persons were also discovered. The highest rate was found at Taoshan Village (9%) and the lowest at Chulin Village (3%). The infection increased with age from less than 1% among those under 10 years of age to a peak of 11% for those over 50 years. The infection rate in males (7%) was similar to that in females (6%). Fourteen percent (43/305) of the families were found with one (91%) or two (9%) infected members. The infected persons had been eating raw meat and viscera of wild boar (70%), flying squirrel (65%), muntjac (58%), wild goat (56%) and the raw meat of other 6 kinds of wild animals. Passing proglottides in the feces (100%) and pruritus ani (91%) were the two most important clinical manifestations. One-third (33%) of the patients had passed proglottides for 21-30 years.

Studies on taeniasis in Taiwan. V. Field trial on evaluation of therapeutic efficacy of mebendazole and praziquantel against taeniasis.

Taeniasis is a major public health problem among the aboriginal populations on Taiwan, and is highly prevalent and wide spread in the mountain areas of 10 Counties. Over 27,000 cases of tapeworm infection are estimated influencing the health and economy in the endemic areas. A treatment of taeniasis with mebendazole and praziquantel followed by a re-treatment with atabrine has been done in the field trial, and confirmed that praziquantel is highly effective agent against tapeworm infection, but mebendazole is not. Based upon experiments reported here praziquantel in a single dose of 150 mg, and 450 mg are highly effective against taeniasis and hymenolepiasis respectively.

Taeniasis, cysticercosis and echinococcosis/hydatidosis in Nigeria: I--prevalence of human taeniasis, cysticercosis and hydatidosis based on a retrospective analysis of hospital records.

A retrospective analysis of hospital records in 3 ecological zones of Nigeria was carried out to ascertain the prevalence of human taeniasis, cysticercosis and hydatidosis. The prevalence of Taenia infection in Sudan, Bauchi Plateau and Northern Guinea zones was 0.9%, 0.6% and 0.6%, respectively. The prevalence of human taeniasis by age and sex in the 3 ecological zones indicates that males were more often infected. Because males by habit eat more "suya" (half-grilled beef) than females, they are more likely to be exposed to Taenia saginata cysts. As for age factor, Taenia infection was more common up to the age of 40. Human hydatidosis was recorded only once in the Sudan zone and was not recorded at all in the Northern Guinea and Bauchi zones. Human cysticercosis was not documented in any of the three ecological zones covered by the survey. It is suspected that the low prevalence or the non-documentation of some of these diseases is due to poor diagnostic facilities and inefficient disease-recording system.

Studies of taeniasis in Taiwan. XIV. Current status of taeniasis among Yami aborigines on Lanyu Island, Taitung County, southeast Taiwan.

In December 1989, 1,457 Yami aborigines in six villages on Lanyu District (Lanyu Island), Taitung County, Southeast Taiwan, were examined by questionnaire and demonstration of the proglottides or by scotch tape perianal swab technique for taeniasis. The overall infection rate was 5%. The highest rate was found at Yehyin (8%) and the lowest at Yujen (2%). However, the rate did not significantly differ among the villages. The infection rate peaked in the 51-60 yr age group (15%) and the lowest rate was observed in the 11-20 yr age group (less than 1%). No infection was found in the 21-30 yr age group. The infection rates of men and women were similar (5%). Twenty-one per cent of 304 families was found to include one or more infected members and a family with five infected person was observed at Yehyin. The infection rate of taeniasis on Lanyu Island decreased from 16% in 1984 to 5% in 1989. However, 51 persons who were negative in 1984 were positive at present, 26 were found to be positive in both studies, and 216 (12 died) who were positive in 1984 were now negative. These results indicate that the Yami people still eat raw meat and viscera of animals.

Control of Taenia solium taeniasis and cysticercosis by focus-oriented chemotherapy of taeniasis.

The mortality, mortality, and disability due to Taenia solium neurocysticercosis are common and serious health problems in some regions, including several Asian countries. Neurocysticercosis in man and cysticercosis in pigs can be controlled by treatment, in man with a single, low (2 1/2 or 5 mg/kg) and safe dose of praziquantel. The problem which remains is the identification of a Taenia solium taeniasis foci. The definition of a focus is: T. solium-infected or suspected case; household with recent case of epilepsy in family or cysticercosis in pigs; group of houses or a village with high rate of cysticercosis in pigs. In a rural area a focus can be easily identified by tracing infected pigs to their place of origin, or in vivo tongue examination. All people with suspected T. solium taeniasis in a focus should be treated.

Mebendazole in the treatment of taeniasis solium and taeniasis saginata.

A study was made of the effect on taeniasis of mebendazole, a drug known to be highly active against a variety of nematode species parasitic in humans. Thirty-seven patients infected with Taenia solium and four with Taenia saginata, some of whom had concomitant nematode infections, were treated with one of three dosages for 3 to 6 days. Within 48 hours of treatment most patients had eliminated long chains of intact, but apparently lifeless, proglottids. Assessment of results was made by monthly post-treatment observations for 4 to 5 months. The optimum effective dose of mebendazole appears to be 300 mg twice daily for 3 days.

Sero-prevalence of Taenia solium cysticercosis and Taenia solium taeniasis in California, USA.

OBJECTIVES: Taenia solium Cysticercosis is a leading cause of epilepsy and neurological disability in the developing world. It is caused by ingestion of the eggs of the tapeworm, T. solium Taeniasis. The prevalence of either T. solium Cysticercosis or T. solium Taeniasis in the United States in populations at risk is poorly understood. The primary objectives of this study are to perform the first study of the sero-prevalence of T. solium Cysticercosis and T. solium Taeniasis in an at-risk community in the USA, specifically rural Southern California; identify T. solium Taeniasis positive individuals, and treat positive individuals for the tapeworm T. solium Taeniasis. METHODS: Community based sero-prevalence study of antibodies to T. solium Cysticercosis and T. solium Taeniasis in 449 subjects living in a federally funded, predominantly Hispanic residential community; and in two migrant farm worker camps in rural Ventura County, California, USA. For this study, fingerstick blood samples were obtained. Serum immunoblots for both T. solium Cysticercosis and T. solium Taeniasis were performed. RESULTS: The sero-prevalence of T. solium Cysticercosis was 1.8% and the sero-prevalence of T. solium Taeniasis by serum immunoblot was 1.1%. Taenia solium Cysticercosis and T. solium Taeniasis antibodies were not detected in children. The sero-prevalence of T. solium Taeniasis was highest in the migrant farm worker community. Handwashing frequency was correlated with T. solium Taeniasis sero-positivity. CONCLUSION: The sero-prevalence of T. solium Cysticercosis and T. solium Taeniasis in this population, as detected by serum immunoblot, approximates the prevalence in some endemic areas of Latin America. Importantly, most patients likely had prior exposure, not active infection. This study establishes for the first time, the relative sero-prevalence of T. solium Cysticercosis and T. solium Taeniasis in at-risk populations in the United States.

Evaluation of taeniasis prevalence in the area supervised by the Provincial Sanitary-Epidemiological Unit in Szczecin between 1994 and 1998.

INTRODUCTION: The aim of the study was to investigate the prevalence of taeniasis in population supervised by the Provincial Sanitary-Epidemiological Unit in Szczecin between 1994 and 1998. MATERIAL AND METHODS: The prevalence of intestinal taeniasis in population of Szczecin Province was evaluated basing on data from the selection charts available in the Provincial and Field Sanitary-Epidemiological Units between 1994 and 1998. The following parameters were analyzed: environment (urban, rural), sex and age groups of patients. Basing on these data the prevalence of taeniasis per 100,000 of citizens was calculated. The study presents also the prevalence of taeniasis according to the species. RESULTS: In the studied period 337 cases of infestation of tapeworms were registered. The incidence of taeniasis in the consecutive years tended to be decreasing. The incidence of taeniasis decreased from 10.33 cases per 100.000 of population in 1994 to 3.52/100.000 in 1998. The incidence rate was higher in urban residents than in rural residents. In the whole analyzed period 82% of cases were noted in patients aged 20-59; however, the highest incidence of taeniasis (30%) was observed in patients aged 40-49 years. Taenia saginata turned out to be the prevalent species. The percentage of unclassified taeniasis (Taenia species) was only 3.3% in the analyzed period of time. It is necessary to improve the accessibility of efficient health care units in the rural environment to make the evaluation of incidence of taeniasis reliable. CONCLUSIONS: Taeniasis, despite its lower prevalence in the consecutive years, is still an epidemiological problem. Better access to effective health care institutions in the rural area is extremely important for reliable evaluation of prevalence of tapeworm infestation.

Risk factors associated with taeniasis-cysticercosis in Lagamar, Minas Gerais State, Brazil.

An epidemiological survey was carried out in 3,344 people of an urban town in Lagamar, Minas Gerais, Brazil--during 1992-1993, to evaluate the main risk factors related to taeniasis and cysticercosis. A total number of 875 (78.9%) houses were visited and 1080 (32.3%) subjects were clinically examined. Poor sanitary conditions were positively associated with former history of taeniasis or seizures in households (p < 0.05). It was remarkable the positive relationship between taeniasis and seizures when households were questioned and subjects were clinically evaluated (p < 0.05). The relative risk of seizures was 2.3 between households and 1.7 for individuals clinically examined respectively. The breeding of swine nearby and the chronic carriers of taeniasis are determinant factors in the maintenance of the epidemiological link between taeniasis and cysticercosis in endemic areas.

[Case report: taeniasis, is it a cause of psychiatric and neural symptoms?].

The most frequent symptom of taeniasis is the discharge of proglottids (93.7%). Gravid proglottids which do not have uterine pores are damaged when they exit the anus by their movement. Because of this damage most of the eggs contaminate the perianal tract. The cellophane tape technique that is used for getting perineum material is also a convenient technique for diagnosis of taeniasis. A 36 year-old woman was admitted to our parasitology clinic complaining of a watering mouth for one year, of abdominal pain, and of loss of appetite for 6 months, and who had discharged proglottids from time to time. She had been eating raw meat since her childhood and had had treatment for taeniasis fifteen years ago. She has also been under treatment for obsessive and compulsive neurosis and depression for two years and complained of constipation that was the side effect of the drug clomipramine HCL. She was given treatment with niclosamide and purgative treatment. The result of the treatment was incomplete because the patient refused to use the purgative. She was called for follow up controls two weeks and six months after treatment and after six months did not have any evidence of infection in her stools. When she was asked, the patient said that she did not need to use the drugs for the treatment of obsessive and compulsive neurosis and depression any more since her symptoms had decreased. According to various authorities, taeniasis is thought to be the cause of psychiatric symptoms due to its neural and psychological effects. These claims have been confirmed in our case because of her psychiatric symptoms decreased after the taeniasis treatment. Thus, the view that there is a relationship between intestinal parasites and psychiatric disease has been strengthened.

Prevalence of taeniasis and enterobiasis among aboriginal children in mountainous areas of Taiwan.

Children numbering 6,197 were tested for taeniasis. Those children were examined from May, 1981 to July, 1989. Sixty one primary schools, in eight mountainous districts provided the test group of children. The method used in these tests was the Scotch tape perianal swab. The overall infection rate of taeniasis was 1%. A total of 6,667 children were also examined for enterobiasis and the infection rate was 10%. There was no significant difference in the rate of taeniasis and enterobiasis by sex. The infection of taeniasis was highest in Tatung District (3%), Ilan County. However, there was no significant difference among the rates by district. The prevalence of enterobiasis was highest in Jenai District (17%), Nantou County and lowest in Lanyu District (2%), Taitung County. Taeniasis was not found among non-aboriginal school children, while 3% of aboriginal school children were infected with Taenia. However, the infection rate of Enterobius vermicularis among non-aborigines (39%) was much higher than that among aboriginal children (5%). These findings indicate that aboriginal children still eat raw meat and viscera of wild animals and acquire Taenia infection.

[Taeniasis, amebiasis and other intestinal parasitosis in school age children from Michoacan State, Mexico].

92.3% schoolchildren aged 6-13 years of a mexican rural village, suspected foci of Taenia solium cysticercosis were screened for intestinal parasites with the main purpose to know the infection rate by taeniasis. An stool sample was collected to schoolchildren of the village and 95.4% of a urban private school as comparative group. Laboratory examinations were performed with the most accurate technics, included microscopies with an ocular micrometer. The general parasitation rate was 4 times higher in the rural village, but the percentages of Taenia spp. infection were 0.6% both of them. Entamoeba histolytica was observed 1.8% and 7.2% in the city and rural village, respectively. All the cases with taeniasis passed T. saginata after treatment with niclosamide. Negative results were obtained with the same chemotherapy in a randomly selected group of 112 schoolchildren which previous stool examination was reported negative. Neither taeniasis were demonstrated in 94 adult persons. These data are suggestive of the great variability on the transmission rates of T. solium cysticercosis in endemic areas and illustrate the faced methodological problems to confirm the diagnosis of taeniasis. By other hand support the hypothesis that estimates of infection rates with E. histolytica have been overdiagnosed in the country. Taeniasis-cysticercosis; schoolchildren; Taenia saginata; amebiasis.

Taeniasis and cysticercosis in Bali and North Sumatra, Indonesia.

It has been reported that three human Taenia species are distributed in Indonesia: Taenia solium, Taenia asiatica and Taenia saginata. T. asiatica is well known in North Sumatra, especially on Samosir island in Lake Toba. T. solium and T. saginata are known from Bali. T. solium is most serious public health issue in Papua (former Irian Jaya). In this report, we briefly review the present situation of these three human Taenia species mainly in Bali and North Sumatra. For community based epidemiological survey, we have adopted and applied questionnaire, microscopic observation of eggs, coproantigen tests, coproDNA tests, mitochondrial DNA analysis and morphology for isolated specimens, serology for cysticercosis and taeniasis. For detection of taeniasis cases of both T. saginata and T. asiatica, questionnaire by expert doctors is perfect to detect worm carriers. Corpoantigen test developed for detection of taeniasis of T. solium is also highly reliable to detect taeniasis carriers in the community. Epidemiological data from these two islands 2002-2005 are reviewed with backgrounds of historical culture, religions and customs.

Mass treatment against human taeniasis for the control of cysticercosis: a population-based intervention study.

An intervention study with mass treatment against taeniasis to prevent neurocysticercosis due to Taenia solium in a rural community in Mexico was performed in 1991-96. Information and biological samples were obtained at the beginning of the study, at 6 months and at 42 months after mass treatment with praziquantel at a single dose of 5 mg/kg. Prevalence rates of taeniasis were measured by the detection of Taenia coproantigens and Taenia eggs in faeces; neurocysticercosis was suggested by clinical data and by serum antibodies in humans and also in swine. A reduction of 53% after 6 months and of 56% after 42 months for human taeniasis was seen after treatment. Late-onset general seizures decreased 70%. Anti-cysticercus antibodies in the human population were reduced by 75% after 42 months. Antibodies in pigs also showed a significant reduction of 55% after 6 months. In conclusion, an impact of mass chemotherapy against taeniasis to control cysticercosis in the short and long term was demonstrated. Praziquantel for tapeworm treatment should not be given at doses lower than 10 mg/kg. Late-onset convulsive crisis and specific antibodies are good indicators of neurocysticercosis and of exposure to the parasite, respectively.

Taeniasis and cysticercosis prevalence in a small village from Northeastern Brazil.

UNLABELLED: Although not considered as an endemic region, the Northeast of Brazil has the necessary conditions for the development of taeniasis-cysticercosis complex. In a previous paper, we demonstrated that Mulungu do Morro municipality, in the State of Bahia, has a high seroprevalence to cysticercosis in epileptic patients. OBJECTIVE: to determine the prevalence of taeniasis and positive cysticercosis serology in the population of Mulungu do Morro. METHOD: blood and stool samples were collected from a random sampling of the population, by family. The identification of antibodies against T. solium cysticerci was made by EITB and T. solium antigens were identified using a polyclonal antibody-capture ELISA. RESULTS: the cysticercosis seroprevalence was 1.6% (C.I. = 0.8 to 2.8%) and the taeniasis prevalence 4.5% (C.I. = 3.0 to 6.5%). Seropositivity to cysticercosis was higher among those who lived in a house of a person testing positive for coproantigen, p=0.017. CONCLUSION: our results demonstrate that the taeniasis-cysticercosis complex is endemic in Mulungu do Morro. We believe that all areas in the world with the same socio-economic and sanitary characteristics are likely to have high prevalence of this parasite.

Epidemiology of Taenia solium taeniasis and cysticercosis in two rural Guatemalan communities.

Taenia solium taeniasis and cysticercosis are known to be endemic in Guatemala but no studies had been undertaken in rural communities where transmission was thought to occur. Two adjacent communities, Quesada and El Jocote, in the Department of Jutiapa were selected. The former had considerably better sanitary infrastructure than the latter. The seroprevalence of antibodies detected in humans by immunoblot to T. solium metacestode glycoprotein antigens was 10% and 17% and the prevalence of intestinal taeniasis was 1% and 2.8% in the two villages, respectively. Both of these represented statistically greater rates in El Jocote. Females were significantly more likely to be seropositive than males in the study as a whole. The majority of cases of intestinal taeniasis were due to T. solium. Cases of intestinal taeniasis were significantly more likely to be anti-cysticercus antibody-positive than the general population. Epilepsy was recorded in 2.8% and 2.9% of the populations of Quesada and El Jocote, respectively. Follow-up of this group and a group of asymptomatic individuals by computed tomography scan indicated that individuals with a history of seizures had a higher rate of abnormalities suggestive of neurocysticercosis. Cysts were present in the tongues of 4% of live pigs sampled in Quesada and 14% in El Jocote. In these two communities, which are probably representative of many others in Guatemala, T. solium appeared to be a significant public health problem.

[Management of taeniasis: comparative evaluation of osmotic non-oily purgatives].

UNLABELLED: The therapeutic protocol in taeniasis associates an anthelmintic drug and a pro-expulsive purgative. The purgative impeds intestinal disaggregation of the worm, facilitating the identification of the species of Taenia and preventing the risk of cysticercosis in case of T. solium infection. AIM: Comparative evaluation of the efficacy of two non-oily purgatives (magnesia usta MU and a lactulose derivative DL) using as anti-parasitic drug exclusively Praziquantel (PZQ), in order to update the treatment of human taeniasis. RESULTS: Regardless the purgative used, cestode shedding rate was of 100% fractionated, with easy to identify cysticerci, but with seldom recognizable scolex. Expulsion is rapid, up to 3 hours with DL and maximum 6 hours for MU, being perceived as uncomfortable, but without major intolerance. Egg shedding following expulsion may be prolonged up to 48 hours, with a significant risk for the patient and the community if T. solium infection. The onset of non-specific post-taeniasis entero-colonic disease was signalled as possible functional sequel. CONCLUSION: The treatment formula for taeniasis with PZQ and an non-oily purgative (preferably DL, yet also MU as cheaper option) ensures rapid and safe expulsion of the worm, allowing meanwhile the morphological diagnostic of species. Controlled expulsion of the taenia demands specialised surveillance in hospital.
