To ascertain the larvae (L3) of Strongyle species in cattle and buffalo present in and around Guwahati, Assam, a total of 3597 fecal samples of cattle (2339) and buffalo (1258) were screened for one calendar year from August 2012 to July 2013. The study period was divided into four seasons viz. pre-monsoon, monsoon, post-monsoon and winter. The selected animals
were categorized according to age viz. calves (<1 year), heifer (1-3 years) and adult (>3 years). Fecal samples found positive for Strongyle group of parasites was subjected to coproculture for obtaining third stage infective larvae (L3). The coproculture of cattle fecal samples revealed presence of Haemonchus (88.02%), Cooperia (3.52%), Oesophagostomum (3.15%), Trichostrongylus (2.94%) and Mecistocirrus (2.38%) larvae in calves; larvae of Haemonchus (58.27%), Oesophagostomum (17.48%), Cooperia (10.54%), Trichostrongylus (10.17%) and Mecistocirrus (3.54%) in heifer and larvae of Haemonchus (86.96%), Trichostrongylus (6.56%), Oesophagostomum (3.52%), Cooperia (2.04%), Pelodera strongyloides (0.75%) and Mecistocirrus (0.17%) in adult cattle. However, in buffalo calves
percent larval composition of L3 revealed highest prevalence of Haemonchus (98.5%) followed by Cooperia (0.92%) and Oesophagostomum (0.42%). In buffalo heifer, larvae of Haemonchus (90-98.5%), Oesophagostomum (2.25-2.5%), Trichostrongylus (1-1.75%) and Cooperia (1%) were observed while in adults buffalo, larvae of Haemonchus (>95%) was predominant followed by Trichostrongylus (1-2%), Oesophagostomum (1-1.33%) and
Cooperia (1.25%). Seasonwise Haemonchus was the predominant L3 in all the four seasons and in cattle the percentage of larvae ranges from 84.66-91.67% while in buffalo it was >98%.
