الملخص: A total of 98 cows and 61 buffaloes showing pyometra were examined for bacterial infection. 51 strain of different types of family enterobaceriaceae recovered from cows suffering from pyometra represented 5 different species. Members of the genera streptococcus and coorynebacterium represented 10.21% and 25.51% respectively. Haemophillu somnus and Listeria monocytogenes were associated with clinical syndromes of pyometra in cows. All specimens obtained from buffaloes with pyometra showing different types of micro- organisms.
Different micro- organisms were isolated from 94.92% and87.14% of endometritis in cows and buffaloes respectively. E. Coli (12.50%) then proteus species (9.82%) salmonella species (8.48%), Morganella morganll (4.91%) and klebsiella species (5.34%) were the most prevalent members of family enterobacteriaceae isolated from cows showing endometrits . Brucella abortus (biovar 7), H somnus, L. monocytogenes , streptococcus pyogenes streptococcus bovis, streptococcus uberis C. pyogenes streptococcus bovis, streptococcus uberis, c. pyogene and c. haemolyticum were alsi recoovred in order other frequency. Members of family enterobacteriacea and other organisms obtained from buffaloes wit endometritis were discussed in details.
Microbial agents isolated from examined retained placenta in both cows (64 cases) and buffaloes (42 cases) and its incidence were observed . Br. Abortus (biovar 7), klebsiella oxytoca and salmonella Alamo were only found in cows suffering from retained placenta but not from buffaloes. The predominant organisms recoverd from retained placenta were: E. Coli, citrobacter freundii c. pyogenes St. pyogenes, proteus vulgaris and L. monocytogenes.
Bacteriological examination of 288 samples of the abomasal contents, liver, spleen, lungs, kidneys and braing of the cows foeti collected from 48 aborted dead foeti revealed the isolation of many pathogens including Br. Abortus (biovar 7 and 3), campylobacter fetus subspecies venerealis, s. abortus bovis, L. monocytogenes, Kl. Oxytoca and others in order of their frequency. It was found that the brain tissue was the most common seat for the isolation of listeria monocytagenes similar to abomasal contents. The seat organs infected with the different pathogens recovered from examined aborted cow’s foeti were discussed in details. The micro-organisms recovered during the early stage of gestation or in the late stage of pregnancy were identified in details.
Established abortifacient organisms isolated from aborted buffaloes were Br. Abortus (34.88%), campylobacter fetus subspecies venerealis (13.95%), s. abortus bovis (13.9%) , s. typhimurium and E. coli as a mixed infection (9.30%). Organisms involved from early as compared to the late months of aborted buffalo- foeti were described. Occurrence of early abortion in relation to the involvement of bacteria was less than that of the late abortion in buffaloes.
The sensitivity of Br. Abortus ( 46 strains), listeria monocytogenes (36), H. Somnus (31), s. abortus bovis (24 ), s. typhmurium (21), s. alamo (14) to seventeen various chemotherapeutic agents were discussed in details.
The incidences of E. Coli infection of genital tracts was more in cows (17.49%) than in buffaloes (15.74%), serological techniques have been used to detect the serovars. E. coli serovars 026:B6, 086:B7 and O126:B7 showed a higher isolation rate from diseased buffaloes than in diseased cows. 055:B5 gave the higher recovery rate in cows than in buffaloes particularly in animals showing endometritis. Also, o119 B14 (5.13%). O126:B16 (2.56%) and O127:B8 (11.83%) were recovered from cows but not present in buffaloes.
The recovery of salmonellae from cows showing retained placenta was considerably lower (0.22%) than that found in cows showing pyometra, endometritis and aborted foeti (9.87%) but the rate was considerably higher in diseased buffaloes (11.89%). The incidence of s. Alamo, s. abortus bovis, s. typhimurium and unidentified salmonella from cows with genital disorders were 2.02%, 4.04%, 1.8% and 2.02% respectively. The serovars associated with diseased buffaloes suffering from genital disorders were s.
