The prevalence of paramphislome infection in sheep slaughtered at Maiduguri abattoir, Nigeria was studied. Of the 100 slaughtered sheep examined, 28.0% were infected, with an overall worm burden of 203. Of 39 males, 23.1% were infested with a worn burden of 63, while of the 61 females examined, 31.1% were infested with a worm burden of 140. Also of the 91 adult sheep, 28.6% were infested with a worm burden of 189, while out of the 9 young sheep, 22.2% were infested, with a worm burden of 14. Among breeds, 50 Balami were examined with 32.0% infested, and a worm burden of 112, while of the 49 and 1 Udda and Yankassa sheep examined 24.5% and 0.0% were infested, respectively. However, the differences in the prevalence of paramphistomes between sexes, age groups and breeds of sheep were non significant. Identification of the parampluistomes of sheep based on their size and predilection site showed Paramhistome cervi to inhabit the rumen with a mean size of 8.5 x 3.5 mm, while Gastrothylax cruminefer inhabited also the rumen but of the size 13 x 5 mm. The distribution of paramphistome species based on the sex, age and breed of sheep examined showed that more females were infested with P. cervi (52.6%) than the males (33.3%), while more males were infested with G. crumenifer (66.7%) than the females (47.4%).
