Abstract
The present study was carried out on 70 genital samples (especially uteri and fallopian tubes) of slaughtered buffalo-cows. These samples were collected from different slaughter-houses of kalioubia, Monofia and cairo provinces, 10 of them were apparently normal. All samples (especially uteri and fallopian tubes) were subjected to gross, bacteriological and histopathological studies.
The gross examination revealed the presence of pathological affections in both uteri and fallopian tubes. The apparent pathological affection in the uteri were endometritis (38.571%), pyometra (7.142%), endometrial cyst (7.142%) and serosal cyste (4.285%). While apparent pathological affection in the fallopian tubes were salpingitis, hydrosalpinx, pyosalpinx, para-ovarian cyst and bursal adhesion with incidene of 57.142%, 8.571%, 12.857%, 2.857% and 4.285%, respectively.
The microbiological studies revealed that the most predominant Grain positive bacteri isolated from apparently normal uterus were Staphylococcus epideruidis (3.289%), Streptococcus faecalis and Corynebacterium renale (1.973% for each), Coryrebacterium bovis, Micrococcus variance and Anthracoids (1.315% for each). While E.coli (4.761%), Enterobacter aerogenes and Klebsiella pheumoniae (3.968% for each) and Citrobacter diversus (2.380%) were the most prevalent Gram negative bacteria. The predominent Gram positive micro-organisms isolated from affected uterus were Corynebacterium pyogenes (17.763%), Staphylococcus aureus (17.763), Streptococcus pyogene (11.184%), Corynebacterium bovis (10.526%) and Staphylococcus epidermidis (9.210). While the most prevalent Gram negative bacteria.
Conclusion : from the present study I would sure say that endometritis may be lead to salpingitis due to spreading of the causative organisn from the uterus to fallopian tube, consequently decrease in the fertility and/or sterility. This mainly cause a large economic losses due to decrease in animal reproduction. So I could advice all farmers and veterinarians to pay attention about sanitary measurments during parturition and early puerperium to avoid the infection and consequent infertility problems.
