The Status of Intestinal Nematode Infectionin Dogs in Nghe An Province

Abstract

Of Autopsy was carried out to investigate intestinal nematode infection in dogs in Nghe An province. A total of 128 dogs from different sites representative of mountainous, lowland and coastal areas of the province were examined. It was found that there were 7 species of intestinal nematodes parasite in the dogs, which were Ancylostoma caninum, Uncinaria stenocephala, A. braziliense, Toxocara canis, Toxocaris leonine,  Spirocerca lupi, and Trichuris vulpis. The total prevalence of intestinal nematodes parasite in the dogs was 70.31%. The prevalence of hookworms varied from 54.84% to 61.11%. In addition to autopsy, 128 faecal samples were examined by Fülleborn method. Results showed that the total prevalence of intestinal nematodes parasite in the dogs was 71.90%. The prevalence of hookworm infection varied from 59.62% to 65.15%. The dogs were least infected with Trichuiris vulpis (5.77%). The highest prevalence of nematodes was recorded in dogs of 2 - 6 months of age. The prevalence of Trichuris vulpis and Spirocerca lupi increased with the age of dogs, while the prevalence of Toxocara canis decreased with the age of dogs. Results also indicated that dogs of all ages were highly affected with Ancylostomatidae
