Isolation, characterization and prevention of various microbial strains in NIC unit and PIC unit

Abstract

The health of the hospital associated persons, particularly those dealing directly with insertion of devices, are serious cause of concern for hospitals. In this study, the most prevalent organism on the surface of medical devices in PICU were CoNS (16.66%) and Staphylococcus aureus (16.66%), while in NICU the most prevalent organism was Klebsiella spp. (11.25%) among Entero-bacteriaceae group followed by Acinetobacter baumannii (10%), Escherichia coli (2.5%), CoNS (6.25%), S. aureus (6.25%) and Enterococcus faecalis (6.25%). The most common species identified from blood specimen of clinical samples shows the maximum presence of Candida sp. (60/135) followed by A. baumannii (21/135), Klebsiella Pneumoniae (20/135), Enterococci (12/135), Burkholderia cepacia complex (8/135), S. aureus (6/135), E. coli (5/135), Pseudomonas aeruginosa (3/135). Different antibiotics have been used against these micro-organisms; but Cotrimoxazole, Vancomycin have been found more effective against CoNS bacteria, Clindamycin, Tetracycline for S. aureus, Nitofurantoin for Acinetobacter, and for E. faecalis, A. baumanii, and Klebsiella, erythromycin, Colistin, and Ceftriaxone have been found more effective respectively.
