Abstract :

 The study was done for 100 blood samples received in the laboratory from patients suffering from haematological cancers solid tumours.The specimens were processed using BACTEC® 9050 (Becton Deckinson Systems) culture systems. A total of 22 (22%) positive cultures were studied. Gram– positive, Gram negative isolates were 9 (9 %), 13 (13%) respectively. Staphylococcus aureus showed 100% sensitivity towards Gentamycin, Amikacin, Netromycine, Amoxyclave. Coagulase Negative Staphylococcus (CONS) showed 100% sensitivity towards Ampicillin and Vancomycin and 100% resistance towards Tetracycline, Ceptoxime, Ofloxacin. Enterococci showed 100% sensitivity towards Ampicillin, Ciprofloxacin, Tetracycline, Bacitracin, Vancomycin, Ceftizoxamine and Amoxyclave whereas 100% resistant towards most of the antibiotics studied. Escherichia coli was 100% resistant to Ceptoxime and 80% resistant to all the other antibiotics tested, Salmonella typhi was found tob be 100% sensitive towards Ciprofloxacin only. Klebsiella showed 100% sensitivity towards Amikacin only. Pseudomonas aeruginosa was 100% sensitive for Pefloxacin , Cefoperazone only.
