A cross-sectional survey was undertaken to identify risk factors and clinical signs associated with parasitic helminth infections of cattle in Mymensignh district of Bangladesh. A non-random convenience sampling method was used to select 138 animals from 40 farmers/herds. The eggs per gram of faeces (epg) for nematodes and trematodes were determined by McMaster and Stoll’s methods respectively. Animal-level and herd-level data were recorded by means of a questionnaire. Multicollinearity amongst explanatory variables were assessed using 2×2 X2 test and one variable in a pair was dropped if P?0.05 for multiple logistic regression models. Association study between outcomdels. explanatory variables was conducted using classification tree, random forests and multiple logistic regression. A positive epg was considered as infected. Analyses were performed using STATA??, version 8.0/Intercrmled and R??, Version 2.3.0. Seventy eight percent (78%) of the cattle were found to be infected with at least one type of helminth. Twenty four (24) pairs of combinations of explanatory variables showed significant associations. Mon animals (OR=3. inp=.006, 95% CI=1.4, 7.7) were associated with significantly increasednpssion modeof nematode infection. Female cattle of the study area are mostly cross-breed, kept indrme, fe. elatively good diet and not used for draught purpose. Mon s are used for draught purpose thereby more exposed to nematode infective stage and provided with Aelatively prme diet. So stressed male cattle may become more susceptible to nematode infection. All of the three statistical techniques selected gender and rumen motility as most important variables in association with nematode infection in cattle. The result of this survey can only be extrapolated to the periurban cattle population of traditional management system.
