| Abstract | ||
| 344 samples were collectd from respiratory tract infections, from March 2006 to January 2007 .Thebacterial isolates where identified basd on colony morphology, biochemical reactions and confirmed using API-NH identification system. 60 isolates(17.4%) identified as a Moraxella catarrhalis, isolated from sputum ,ear, nose, bronchial and tonsillitis swabs in (12.5 ,30 ,27.6 ,11.7 and 6.7)% respectively . 31 (16.3%) isolates were recovered from males samples versus 29 (18.8%) isolates from females. Some virulence factors of Moraxella catarrhalis were studied ,the results revealed that 58 (96.7%) isolates have adhesion factors to humans epithelial cells. 22 (36.7%) isolates have ability to produced protease enzyme . Versus , 54 (90%) isolates produced lipase . however no isolates have ability to produced heamolysin. As well as no isolates produced capsule | ||
