S. M. Z. H. Chowdhury, M. F. Mian, N. C. Debnath
Rectal fecal samples from zebu cattle (Bos indicus) at Savar, Dhaka, were collected in every two months of the year from March, 1987 to February, 1988 and were examined using Stoll`s dilution technique. Out of a total of 737 fecal samples examined in six periods, 589 (79.9%) samples were found to be positive for one or more helminthes. Overall prevalences for fasciola, paramphistome, schistosome, strongylids, ascaris, strongyloides, trichuris and capillaria infestations were respectively 19.5%, 48.0%, 5.9%, 52.2%, 1.5%, 2.5%, 5.5% and 12.7%. Prevalences of fasciola, paramphistome and schistosome infestations were significantly (p<0.01) higher from middle of August to December. Strogylids, trichuris and capillaria infestations were significantly (p<0.01) higher from July to October, although strongylids infestation also increased during Kanuary-February. Significantly (p<0.01) higher fasciola and paramphistome infestations were observed in animals after one year of age, whereas strongylids, ascaris, strongyloides and trichuris infestations were significantly (p<0.01) higher in cattle upto one year of age. Fasciola infestation was significantly (p<0.01) higher in female cattle and significantly (p<0.05) higher strongylids infestation was found in males.
