INTRODUCTION: Gram negative bacilli are the important causes of common clinical infections. Carbapenem resistant Enterobacteriaceae are considered as important public health threat and is classified as urgent by the Centers of Disease Control and Prevention because of their progressive geographic dissemination and limited therapeutic alternatives. This study was done to find out the resistance pattern of Carbapenem among Enterobacteriaceae.
METHODS: The descriptive cross-sectional study was carried out in Clinical Microbiology laboratory from February 2018 to May 2018 after ethical approval. Organism was identified on the basis of its microscopic observation by performing Gram's stain and by identification of morphology after its growth in culture media followed by its biochemical reactions. Antibiotic sensitivity test of isolated pathogens was done using Muller Hinton Agar by the standard disk diffusion technique of Kirby-Bauer method.
RESULTS: In our study, total 1055 sample belongs to the family Enterobacteriaceae. From the family Enterobactericeae, 348 (27%) of the bacilli were found to be Carbapenem resistant. Among which most common bacteria was Klebsiella pneumoniae followed by Escherichia coli. All strains of Carbapenem resistant Enterobacteriaceae were sensitive to Colistin, Polymyxin B and Tigecycline.
CONCLUSIONS: Among Enterobacteriaceae, around one-third of the bacterial isolates were Carbapenem resistant. However, to reduce drug resistance antimicrobial stewardship programme and proper infection control measures is required.
