Nematode parasite infections of domestic pigs in a sub-tropical and high-rainfall area of India.
Fourteen hundred and ninety-six domestic pigs, Sus scrofa domestica L., from a sub-tropical and high-rainfall area of India were examined over a period of 18 months to ascertain their nematode parasite spectrum. The eleven species recovered, arranged in descending order of prevalence, are as follows: Ascaris suum, Oesophagostomum dentatum, Bourgelatia diducta, Stephanurus dentatus, Globocephalus connorfilii, Physocephalus sexalutus, Ascarops dentata, A. strongylina, Pseudocruzia orientalis, Setaria bernardi and Gnathostoma hispidum. This is also the first report of the occurrence of Setaria bernardi in pigs in India. A. Suum, the most prevalent species (51.67%) found in the pigs of the region, is presumably of zoonotic importance. Another species of public health significance that was encountered in the survey was Gnathostoma hispidum. The overall infection rate was considerably higher (76.42%) in the low-altitude region than in the high-altitude one (62.50%). The highest level of infection (73.2%) was observed during autumn and the lowest (63.0%) in winter.
