| Summary: | The study included 82 clinical mastitic cows (328 quarters) in two dairy
cattle stations, 15 cows in the first station in Baghdad and 67 cows in the
second station in Babel, Clinical inspection was conducted on cows and it’s
udder, milk samples were collected under sterile condition and subjected for
physical, chemical & bacteriological examination with antibiotic sensitivity
test of the isolated pathogens.
The mastitic cows in each station were divided into two groups, the 1st
(Treated group) in which cows treated by us and the 2nd (control group) in
which cows were treated by the staff of station. After treatment all cows
were examined clinically and bacteriologly four times (once 10 days). Swaps
from milker’s hands and milking machine were also taken.
The results revealed that out of 328examined quarters, 212 quarters were
infected (55 quarter in the 1st station and 157 quarter in the 2nd station). The
acute form of mastitis represent high percent and the occurance of the
disease increased with the advance age. The hind quarters were more
frequently affected than fore ones.
Staph.aureus was the only isolate from the 1st station, while 14 type of
bacteria was isolated from the 2nd station .Staph. aureus & Staph.epidermidis
were isolated from milker’s hand,where as Bacillus cereus, Klebsiella
pneumoniae . & Pseudomonas aeruginosa & Pasteurella spp. were isolated
from teat cups. |
