Determination of bacteria causing bacterimia in infants with unknown origin of pyrexia

Abstract EN

The research deals with Isolation and Identification of pathogenic bacterial species from pyrexia of unknown origin cases in infants and determination pattern of antibiotic profile of the most common isolating bacterial species.(150)blood samples were taken from infants below 36 months who were referred to Ibn-Sina Hospital in Mosul city suffering from pyrexia ,then the biochemical, morphological and cultural tests were done on the samples.

The results showed positive blood culture for only (50) samples and the following bacteria were isolated: Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, viridians group Streptococci, Pseudomonas aeruginosa in percentage 68%, 16%, 10%, 4%, 2% respectively.

Antibiotic sensitivity test performed for Staph.aureus as a high ratio isolated bacteria and the results showed that Gentamycin and Amoxiclav has great activity against Staph.aureuseus, the percentage of sensitivity were 82.35%, 73.52%, respectively.

The strains showed high resistence against Ampicillin, and Co-trimoxazole, While it showed sensitivity against vanconycin at 32.35%.-
