Adnan M. AL- Rodhan
Fifty liver and lung samples (25 for each) were examend for the presence of Staphylococcus aureus . The rate of S. aureus isolates were 60 and 56% in livers and lungs respectively. Identification of S. aureus isolates were performed by studying, it's cultural characteristics on mannitol salt agar and testing their pathogenicity factors (Coagulase, haemolysis and B-lactmase production), 72.4% of isolates were coagulase positive, 58.6% were β-lactamase producer, 62.1% were β-haemolytic and 37.9% were α-haemolytic. There was a difference in the ablity of S. aureus isolates to produce B-lactamase concerning the time of decolourization when iodometric assay was used.
