Keywords:Anthelmintic, Gastrointestinal nematodes, In vitro, Prevalence, Medicinal plants
The prevalence of natural gastrointestinal nematodes was observed in cattle during the period from June, 2004 to May, 2005 in Sadar upazila of Mymensingh district. The prevalence of gastrointestinal nematodes was 84.1% (rainy seasons-97%, summer-85.5% and winter seasons-69.8%). The prevalence of strongyles (Haemonchus sp., Trichostrongylus sp., Oesophagostomum sp. and Mecistocirrus sp.), Bunostomum sp., Strongyloides sp., Trichuris sp. and Capillaria sp. were 63.9%, 26.3%, 21.5%, 17.3% and 24.5%, respectively.
