Situation on gastrointestinal nematode and gnathostoma infection in pigs in Lai Chau province

Abstract

A total of 1,212 fecal samples of pigs at all age groups collecting in 3 districts (Tam Duong, Tan Uyen and Than Uyen districts) in Lai Chau province were tested by Fülleborn method for determining the gastrointestinal nematode and gnathostoma infection rate and intensity in pigs. The testing results showed that there were 5 species of gastrointestinal nematode and 1
Gnathostoma species found in pigs, namely Macracanthorhynchus hirudinaceus, Ascaris suum, Trichocephalus suis, Strongyloides rasomi and Oesophagostomum dentatum, respectively. The overall infection rate of pigs with gastrointestinal nematode and gnathostoma species was 71.62%, vacillating from 60.89% to 79.46%. Of which, the highest rate of pigs infected with nematode and gnathostoma was in Tam Duong district (79.46%) and the lowest rate was in Than Uyen district (60.89%). The infection intensity mainly occurred in the mild and moderate levels (49.08% and 30.53%, respectively). The infection rate of pigs with gastrointestinal nematode and gnathostoma gradually increased from 2 months old to 6 months old. The factors including location, seasons and husbandry method significantly affected to the incidence of
gastrointestinal nematode and gnathostoma in pigs with P < 0.05.
