Only in Dapaong, in North Togo, and Bawku, North Ghana, have larger series of clinical cases been described. In the rural areas around these towns, a survey was made in whi...

Anthelmintic efficacy of levamisole, albendazole, ivermectin and morantel tartrate was evaluated in 75 sheep naturally parasitized with Haemonchus, Trichostrongylus, Oesophagostomum and Ostertagia spp. Results revealed that levamisole, albendazole, ivermectin and morantel tartrate were lOO, 98.82, 97.02 and 76.50 per cent effective, respectively in reducing the eggs per gram of faeces. The anim...

Feline coprolites were examined for parasites with the aim of studying ancient infections that occurred in the Patagonian region during the Holocene period. Eggs compatible to Trichuris sp., Calodium sp., Eucoleus sp., Nematodirus sp., Oesophagostomum sp. (Nematoda), Monoecocestus sp. (Cestoda) and Eimeria macusaniensis (Coccidia) were recovered from faecal samples. The results obtained from th...

To estimate the reliability of ultrasound for the detection of colonic wall pathology induced by the intestinal parasitic helminth O. bifurcum, three studies to assess the intraand inter-observer variation of the technique were performed. In the endemic area of northern Ghana, 181 people from a low prevalence village and 62 people from a high prevalence village were examined twice by the same o...

Natural habitat fragmentation and reducing habitat quality have resulted in an increased appearance of Japanese macaques, Macaca fuscata (Gray, 1870), in suburban areas in Japan. To investigate the risk of zoonotic infections, a coprological survey of helminth eggs passed by wild Japanese macaques was carried out in 2009 and 2010 in Shiga Prefecture, Japan. Microscopic examination found helmint...

Faecal samples were collected from fifty three freshly captured monkeys which were kept at the Barbados Primate Research Centre and Wildlife Reserve (BPRCWR). Examination of these samples for gastrointestinal helminths using the zinc sulphate floatation method revealed an overall infection rate of 88.7%. The parasites observed included Strongyloides (62.4%), Physaloptera (58.5%), Trichuris (52....

To determine association of grassland with parasitic diseases of livestock in Bangladesh, the 'Tracer' animals (two cow calves and two goats) were released for a month in a grassland used for communal grazing of livestock near school premise in Kanthal, Trishal, Mymensingh, Bangladesh. After slaughtering of the tracer animals, their gastrointestinal tract examination revealed six species of nem...
