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.
