Abstract
Milk samples were randomly collected from apparently healthy udders of 1034 milking Friesian cattle for bacteriological examination. 122 atrains were isolated with a recovery rate of 11.8% of the samples. Microorganisms secured were coagulae-positive Staphylococci (60.66%), Streptococci (31.14%) including Str. agalactiae (16.3%), Str. dysgalactiae (11.4%) and Str. uberis (3.2%). In addition, E. coli and C. pyogenes were recovered with an incidence of 4.9% and 3.2% respectively while the recovery rate of double infection was 51.2%.
The secured organisms were sensitive to the following sntibiotics in a descending order: Kanamycin, Erythromycin, Polymyxin, Strepto mycin and Penicillin.
