Abstract
Aim:
The main objectives of this study were to determine the incidence
of
Sarcocystis
sp. infection in cattle and buffalo carcasses slaughtered at El-Kharga
abattoir, New Valley Governorate, Egypt.
Materials and Methods:
The slaughtered animals were daily inspected for
Sarcocystis
macrocysts through a year (2015). Macroscopic
Sarcocystis
was detected from a total of 2120 cattle and buffalo carcasses. In
addition, 100 meat samples were collected from female cattle and
buffalo (50 each) and were examined microscopically for
sarcocystosis.
Results:
The overall incidence of
Sarcocystis
macrocyst among bovine carcasses was 159/2120 (7.5%). Total
incidence in cattle was 149/2000 (7.45%), whereas it was 10/120
(8.33%) in buffalo carcasses. Concerning gender, the overall
prevalence of
Sarcocystis
infection was 127/1790 (7.09%) in male and 32/330 (9.69%) in
females bovine carcasses. The highest detection rate of
Sarcocystis
lesions was from the esophagus (76.3%) followed by throat muscles
(35.3%), tongue (33.8%), and diaphragm muscles (18.71%).
Macrocysts from cattle were identified to
Sarcocystis hirsuta,
whereas
Sarcocystis fusiformis
was identified from buffalo carcasses. By microscopic examination,
18 (36%) of 50 female cattle carcasses harbor
Sarcocystis
sp., whereas 11 (22%) of buffalo carcasses were harbored
Sarcocystis
microcysts.
Conclusion:
A
high incidence of
Sarcocystis
infection was detected among slaughtered bovines in El-Kharga
abattoir, Egypt.
Sarcocystis
macrocysts were a higher incidence in female elder animals
macrocysts were identified to
S. hirsuta
in cattle and
S. fusiformis
in buffaloes. Sarcocystosis constitute a major cause of economic
losses at El-Kharga abattoir. Beef meat may carry health risks to
consumers.
