The eggs of Strongyloides westeri were found in the faeces of the foals from the 16th day of their life, with a peak in their numbers between the 30th and 40th day of life. Egg release ceased in all foals irrespective of their date of birth in the months July-August. Parallel examinations of the mares were negative. Recommendations for the control of strongyloidosis in foals are given.
In order to determine the epidemiological factors and clinical symptoms associated with Strongyloides stercoralis infection, we carried out a descriptive study with a control group in the District of Chanchamayo, Province of Chanchamayo, Junin, Peru. Group I (n = 50) represented those individuals with strongyloidosis and group II (n = 50) were those who tested negative for S. stercoralis by parasitological methods. Epidemiological variables significantly associated with group I were: bathing in the river 3-4 times per week, consuming non-drinking water, defecating in the field; and with group II: drinking boiled water, wearing sneakers and living in houses with cement floor. The clinical symptoms of epigastric pain, daily abdominal pain, semi liquid feces, liquid feces, daily defecation frequency, urticaria and nausea were significantly associated with group 1; whereas more solid feces and defecating every other day were significantly associated with group II. Among individuals under the age of 20 there was a higher percentage of malnutrition according to the weight-age index in group I (p = 0.045). We conclude that infection by S. stercoralis should be suspected in persons from tropical areas who are in frequent contact with rivers or streams or live close to watercourses, who have gastroenterological or dermatological symptoms or who are malnourished, especially if they are children or adolescents.
The paper describes a case of gastric strongyloidosis in a man of 30, imitating ulcer for which unjustified stomach resection has been performed.
A case of strongyloidosis and giardiasis was observed in a women aged 62 years. The treatment included tinidazole, metronidazole and ercefuryl. Modern views on the epidemiology, clinical course and therapy of this parasitic infestation are discussed.
Enterokinase and alkaline phosphatase activities in the duodenal juice and fecal extract of 37 strongyloidosis patients living in moderate climate and 17 inhabitants of the tropics have been studied. In 60.7% inhabitants of the regions with moderate climate and 80% from the tropics decreased enterokinase activity in duodenal juice has been observed, while the decrease in alkaline phosphatase activity in fecal extract has been noted in 87.8% and 71.4% cases, respectively. After convalescence from 1 to 6 months, no normalization of intestinal enzymatic activity has been observed.
The article reports important diseases and different farming techniques of nutria. E. coli and salmonella infections are the most important bacterial diseases. Coccidiosis and strongyloidosis are frequently observed in nutria farms. Differentiated prophylactic treatment and hygiene are necessary for optimal breeding conditions.
About one case of massive strongyloidosis becoming out of any immunosuppressive treatment and without travel out of France in a 40 year-old-woman, the authors study the different possibilities of contamination and set the problem of a drug-resistance to Thiabendazole.
Opportunistic parasitosis and mycosis are becoming ever more widespread, mainly under the influence of major immunodeficiencies, either acquired (AIDS) or therapeutic. In this general overview, their main aspects, both clinical and epidemiological, are underlined. In terms of epidemiology, three types of phenomena have been observed: 1) emergence of human parasitosis unknown before (microsporidiosis due to Enterocytozoon bieneusi, Encephalitozoom hellem or Septata intestinalis); 2) among the human parasites already known, identification of very pathogenic strains (Toxoplasma gondii, Aspergillus fumigatus, Cryptococcus neoformans); 3) origin probably or certainly nosocomial of certain infections (pneumocystosis; toxoplasmosis and visceral leishmaniasis transmitted during bone-marrow or organ transplantations). The development of deep mycosis (invasive aspergillosis) is particularly promoted by granulopenia and alterations in the phagocytosis. On the other hand, opportunistic protozoosis (toxoplasmosis and leishmaniasis) and helminthiasis (strongyloidosis due to Strongyloides stercolaris) are related, above all, to disorders in cellular immunity (deficit of CD4+, mainly). Finally, several of these infections may be characterised by a variety of clinical pictures and outcome, depending on the contributory factors (immunodeficit or not) which led to the development of the infection.
Studies of gastro-intestinal parasites of zebu calves were carried out in traditional herds in Northern Cameroon through monthly faecal analysis in 17 herds for a period of two years. Toxocarosis appeared to be the most important parasitic infection in the North province where its prevalence reached 58% in calves aged 0-6 months; 60% of the infested calves passed large numbers of eggs at least once. Samples revealing high egg counts were more frequent in the dry season. Deworming calves aged one month with a cheap anthelmintic against Toxocara is likely to be economically profitable in the North. Seventy-five and a half per cent of the calves 0-12 months old were infested with Strongyloides; high counts of Strongyloides eggs were registered at least once for 31% of these calves. As for toxocarosis, calves seemed to be more often and more heavily infested with Strongyloides in the North than in the Far North province. Strongyloidosis was apparently of low clinical importance, with the rare clinical manifestations accompanied by toxocarosis. The importance of digestive tract strongylosis was difficult to evaluate. Every steer was affected at one stage of its life in a similar manner in the two provinces; 6.8% of samples showed high egg counts and 35% of the steers aged over six months passed large numbers of eggs at least once. These results did not permit a priori recommendation of a systematic deworming programme against strongyles; instead, several less intensive deworming programmes have to be tested in order to determine their economic profitability. Coccidia were found in 77.4% of calves aged 0-12 months, with heavier and more frequent infections in the North. However, infections of high intensity were generally rare. Trichuris, Moniezia, Fasciola and paramphistomes were rarely found. Concerning nematodosis, curative treatments and cost-profit studies of deworming programmes should be aimed at toxocarosis in calves aged 0-3 months in the North, and strongylosis in steers aged 6-12 months, in both provinces.
Travellers returning from the tropics frequently consult a physician even if they have no actual symptoms. Physical check-ups in asymptomatic returnees rarely detect dangerous conditions. The most common laboratory finding is intestinal parasites. Blood eosinophilia may indicate helminthic infections, such as strongyloidosis, filariasis, schistosomiasis and others. If there are no diagnostically suggestive symptoms a systematic, step-by-step workup is recommended (stool parasitology, serology, and special methods to demonstrate parasites in blood or tissues). The most common symptom of returnees from the tropics is diarrhea, or other disorders of intestinal motility. Appropriate investigations include parasitological and bacteriological tests, and--if the course is more chronic--endoscopy. If diarrhea is associated with fever, systemic infections (e.g. falciparum malaria) must be considered. Fever as a leading sign may mask a number of potentially dangerous infections. If there are no other obvious signs or symptoms indicating a particular etiology, the diagnostic approach should consider first of all those systemic infections, which are potentially life-threatening and can be cured by specific therapy, i.e. bacterial meningitis, falciparum malaria, septicemia (including typhoid fever), extraintestinal amebiasis, and African trypanosomiasis.
The discovery of Strongyloides stercoralis, a parasite of human gastrointestinal system and lungs, was presented from the historical point of view. The sequence of achievements, in regard of explanation of the parasite's life cycle, determining its ways and invasion sites and discovering a different kind of autoinfection in strongyloidosis cycle, was described.
The efficacy and tolerance of medamin therapy for patients with strongyloidosis were studied in a focus of this disease in the Lenkoran District of Azerbaijan, situated in wet subtropical climatic zone. The studies were carried out at 6 rural hospitals. A total of 166 inpatients (n = 48) and outpatients (n = 118) were treated. The drug was sufficiently well tolerated and effective: 65.6 +/- 3.6% of the patients were cured after a single course of therapy. Complete cure was attained after 4 therapeutic courses.
Invasions of gastrointestinal nematodes proved to be the most frequent helminthiases in new-established large-capacity herds of cattle according to the results of parasitary examinations of cattle in one locality in the Tachov district. The nematodes, especially Oesophagostomum spp., Haemonchus contortus, Cooperia spp., Trichostrongylus spp., occurred in animals of all age categories. The Ostertagia spp., Chabertia ovina, Nematodirus spp., Bunostomum phlebotomum and Trishuris spp. participated in the invasions to a smaller extent. The first eggs can already be found in three months old calves. Strongyloidosis can be diagnosed in the first month of age in calves [5%], the incidence rate increasing up to the age of five months, then it begins to decrease. Taenasis was found out in six months old calves [4.4% and11.6%]. Reclamations of pastures reduced the incidence of fasciolosis to the minimum rate; its invasions were heavy before establishing the large-capacity herds of cattle. Dictyocaulosis was not found in the large-capacity herds of cattle at all, due to the same reasons. Not only were nematode eggs proved, but also larvae to develop to the stages capable of invasion [Chabertia ovina, Haemonchus contortus, Oesophagostomum spp., Strongyloides papillosus] in dry excrements on railings of pens, on slatted floors and walls of the calf-sheds that were investigated.
