Studies on renal bacterial affections in sheep in matrouh governorate [electronic resource]

Includes bibliographic reference.

Urine and tissues samples were collected for bacteriological examination from 50 apparently
diseased sheep of different ages and sexes which were clinically suspected suffering from
renal infection and from slaughtered animals. We were collected samples from many
locations at Matrouh Governorate and sent for laboratory. Post mortem examination of the
renal system of affected cases revealed different investigations. kidneys appeared swollen, its
surface was mottled red. Some kidneys were pale and greatly enlarged. Cut section of the
kidney showed areas of hemorrhage and abscess formation. The results indicated that 80%
(40) sheep were positive for bacterial infection however 10 show negative results of bacterial
renal infection. Bacteriological investigations revealed that the isolated organisms were:
Escherichia coli (20%), Staphyolcoccus aureus (25%), Pseudomonas aeruginosa (5.0%),
Streptococcus spp. (7.5%), Enterococcus faeclis (7.5%), Corynebaeterium spp. (17.5%),
Klebseilla pneumoniae (2.5%). and. Listeria monocytogene (2.5%). Moreover, mixed
infection found in 12.5% of the examined samples. A total of eight isolates of E coli from
renal examined samples were serologically positive to O111, O104, O26, O113, O91, O103
and O126. PCR results showed that two strains for Listeria isolates were Listeria
monocytogenes and some of them have InI B gene.
Antibiogram was applied upon the isolated bacterial pathogens and found that Garamycine
was the drug of choice for treatment of infected animals.
