The aim of this study was to investigate various helminth infections of laboratory mice, musk rats as well as in wild rats which were trapped from various areas of Aizawl. The study showed that the laboratory mice were infected with mostly two species of cestodes and one species of nematode. The musk rats were found to be infected with one species of cestode namely Rodenolepis microstoma and one species of nematode, Capillaria hepatica. However, Trichinella sp larvae could be recovered from muscle of wild rats. The prevalence of helminthic infection in laboratory mice were Hymenolepis diminuta (30%), Hymenolepis nana,(20%), Cysticercus fasciolaris (5%) and Syphaciamuris (10%), respectively. In musk rats, Rodenolepes microstoma (5%), Capillaria hepatica(5%) andin wild rats Trichinellasplarvae(1%) were recorded. Since most of the helminths found in rodents are of zoonotic importance, the results suggest that rats either domestic or wild may be acted as a source of helminth transmission to human in this region of India.

This study reports the results of a copro-parasitological investigation undertaken in seven cities located in the South-East of Côte d’Ivoire from 1996 to 2001. The stools of 2551 pupils aged from 4 to 15 years old including 1351 male subjects and 1200 female subjects were subjected to a direct examination, of the Kato and Baermann techniques. Moreover, the research of oxyure eggs was done by the Graham scotch anal test. The study revealed that 41,5 % of the pupils were mono or poly parasited with a statistically significant difference between the two genders. The most affected age group range is the one between 10 to 15. The most affected cities were Grand-bassam (59,70 %), Abidjan (51,42 %), Divo (47,50 %). Trichocephalosis, ascaridiosis and ankylostomosis represented respectively 18,57 %, 11,53 % et 9,94 % of the intestinal helminthosis found. The other worm infestations were rare.
