Clinical and Bacteriological Study of Subcutaneous abscesses caused by gram positive bacteria in cow and sheep in Al-Qadissiyia province

Abstract

In spite of the fact that subcutaneous abscesses is occur in sporadical cases and cause low morbidity, A total of 79 (56 and 23) abscesses of cattle and sheep respectively were examined during 12 month from November 2010 to October 2011 for determined an anatomical distribution of subcutaneous abscesses with identification of clinical features and isolation of causative agents that cause these abscesses in cow and sheep in Al-Qadissiyia province. The head was most commonly affected, followed by (glutcal &neck) and chest regions at percentages 80.36%,10.71% and 8.92% respectively in cattle, and 82.6%, 13.03%, and 4.34% respectively in sheep. Also the results demonstrated that there are four types of subcutaneous abscesses vary in size (from a nutmeg fruit size up to a muskmelon).Fifty four samples out 56 abscesses samples of cattle were demonstrated gram positive bacteria only which presented by Staphylococcus aureus, S. epidermidis, S. hycus, Arcanobacterium pyogenes, and Corynebacterium pseudotuberculosis at percentage (33.9 %), (17.8%), (12.6%), (23.2%) and (7.1%) as well as one sample (1.8%) revealed undifferentiated bacteria, the rest two samples (3.6%) don't showed any bacterial growth during culture. In sheep the 23 samples the result showed that Staphylococcus aureus was predominant bacterial isolates followed by Arcanobacterium pyogenes ,and Corynebacterium pseudotuberculosis , S. epidermidis, at percentage (30.4%), (26%), (21.7%) and (17.4%) as well as one sample (4.4%) didn’t revealed any growth.
