Abstract

Staph.aurous and staph.epidermidis were commonest gram posit ive bacteria, whilst p.aeruginosa wa s mo s t commonest gram negat ive in all samples, and it was has occupied first ranked in the six s t u d y groups, where urine sample have more presence of these bacteria as well as urine sample are more sample which isolated bacteria from it, frequency of isolated isolate was greater in male. Aim of study: To determine the most common types of bacteria affecting different sites of infections. Results: cultures were collected from urine, wound, burn,blood,sputum and Ear swabs. Out of 721 samples collected from different site of infection 54.8% were male except in UTI samples were Females more than males. The most common microorganisms which affect the patients were of gram –ve types (58%) except in ear swab it was found that gram +ve were more than gram-ve (47.7%). The most common type of g+ve was Staphylococcus aureusi 40.4% and Staphylococcus epidermidis, 37.5%, while Pseudomonas aeruginosa and Klebsiella spp were the Most prevalent types of g-ve bacteria. On conclusion most of infections occur in the body were due to g-ve bacteria this turn the mind to the type of antimicrobial drugs to be choosen for treatment.
