A Clinical Report on thePrevalence of Gastro-Intestinal ParasiticInfection in Buffalo of Noakhali, Bangladesh

Abstract

Parasite is one of the major obstacles to the way of maximum production in dairy industry of all over the world. This investigation was conducted to measure the prevalence of GI parasites of buffalo in Noakhali, Bangladesh and its associated risk factors (age, sex, nutrition status and deworming history). Total 100 fecal samples were collected from February 2022 to April 2022. A well-structured questionnaire was used to collect the information relevant to the objectives of the study. Then these samples were examined through flotation and sedimentation technique to pick up the positive samples. The overall prevalence found was 56%. About 13 species of parasite were found in these tests, among which 8 nematode, 3 trematode and 2 protozoa were found. The highest amount of egg found was of Toxocara vitulorum, nearly 32%. The calves tested more vulnerable to the helminths infection than young and adult animals. The prevalence was 72.2% in calves, 65.76% in young and 54.48% in adult buffaloes. Also, the males have higher prevalence than the female animals. Male buffaloes were 1.25 times more prone to GI parasitic infection than the female buffaloes. Moreover, the poor health animal also seems to be more prone to infection compared to moderate and good health animal. A significant difference was noticed in the prevalence of GI parasite in poor health and good health buffaloes. Further work can be done to confirm molecular identification of the helminth species and also the economic effect of parasitic infection in buffalo
