Out of the total examined samples,2 buffaloes samples (6.9>0) preyed to be bacteriologicnllysterile. While all cows samples preved to bo bacteriol-ogically positive.(2) A variet y of micro-organisms were isolated from non-pregnant buffaloes and cows samples, the most importantof which were: StaQh. aureus, Str. bovis, S-[;r. pYQ&enes,Str. zymogenesp C. bovis~ unclassified corynebacteria?E .• coliand aerobacter species in their order of f’r-e qu-ency.(3) The results revealed the fact that;during the oestrusphase, the percentage of bacteria is~~ted was muchlower than that obtained during c.lioestrus in buffaloesand cattle.It was also preved that animals suffering from in--active ovaries showed bigh percentage of the isolatedbacteria than those affected with follicular cyst.
