ABSTRACT
This research was
carried out at the Yelwa-Shendam abattoir, to isolate trematodes from the liver
of sheep and goats slaughtered at the abattoir. 130 animals (70 sheep and 60
goats) were observed prior to their slaughter and their livers inspected for
trematodes (flukes) after the slaughter (post-mortem). 99 animals (56 sheep and
43 goats) had no diarrhoea while 31 (14 sheep and 17 goats) had diarrhoea. 41
(31.54%) and 89 (68.46%) parasitized and not parasitized by the trematodes
respectively. Presence of mucus (running nostrils) was another parameter used.
99 of the animals were without mucus running their nostrils while 31 had
running nostrils with percentage of parasites as 31 (23.33%) with the trematodes and 99 (76.15%)
without the trematodes. It was also discovered that the liver of highly
infested animals were badly damaged by the trematodes which reduced the market
value of such products.
INTRODUCTION
Trematodes
(flukes) are parasitic flatworms that infect the blood vessels,
gastrointestinal tract (GIT), lungs or liver, fore stomach or blood vessels of
most ruminants. They are often categorized according to the organ system they
invade (Ferreras-Estrad et al 2007).
They are among the flatworms under the phylum Platyhelminthese, class Trematoda
and sub-classesAspidogastrea and Digenea.Read more>>>>
