Abstract Paramphistomosis (or amphistomosis) is a snail born disease of wild and domestic ruminants, has economic losses as the infected animals showed digestive disturbance and losses in body condition. The present study was conducted on 689 animals (446 buffaloes, 185 cattle, 33 sheep and 25 goats) of various age and sex in four localities at Sharkia and Daqahlia provinces, in Egypt (Zagazig, Diarb Negm, Ibrahimia and El-Senbellawein abattoirs), during a period extended from October 2012 to March 2014 to determine the prevalence of paramphistomes species and their seasonal prevalence, age and sex susceptibility of these animals to the infection, identification of the examined flukes and molecular studies of Paramphistomum cervi by using ITS2 depending on species specific primer to this species. Concerning the overall prevalence of paramphistomes species among slaughtered buffaloes, cattle, sheep and goats was 12.6% (87/689). The prevalence rate of paramphistomes was higher in buffales (14.6%) than in cattle (1l.9 %) while, No paramphistlomes infection were detected in sheep and goats. The result showed that, the collected flukes from rumen and reticulum of freshly slaughtered buffaloes and cattle were identified as Paramphistomum cervi (1l.7%), Paramphistomum ,- microbothrium (1.6%) and Cotylophoron cotylophorum (1.3 % ) in buffaloes; while in cattle was 9.2%, l.1 % and l.6% respectively .The morphological description of the collected flukes was discussed. |
