Abstract

The present investigation has been undertaken to study the Molecular newlinecharacterization of Fasciola species in sheep and goats of Andhra Pradesh, India . newlineSlaughter/ necropsy examination of 5192 sheep and 2070 goats livers revealed 124 newline(2.38%) and 29 (1.40%) positive for Fasciola spp. with an overall prevalence rate of newline2.10%. Higher prevalence was recorded in female sheep (3.50%) and goats (1.70%) newlinethan males of sheep (2.10%) and goats (1.24%), respectively. Highest prevalence was newlinerevealed in youngs (2.61% and 1.62%) than in adults (1.86% and 1.25% in 1-3 yrs and newline2.11% and 1.22% in more than 3 years age) in sheep and goats, respectively. Highest newlineinfection rate was recorded in summer (2.89% and 1.53%) followed by winter (2.35% and newline1.51%) and rainy seasons (1.19% and 0.91%) in sheep and goats, respectively. Present newlineinvestigation also revealed that the prevalence of Fasciola spp. was the highest in April newline(6.05%) in sheep and in March (4.13%) for goats.
