Aim: To assess the prevalence of enterobacterales in hospital acquired infections and hospital environment. Material and Methods: Enterobacteriaceae from patient isolates and high touch surfaces in the hospital environment were identified using conventional and automated methods in the bacteriology laboratory. The antibiogram of both patient and hospital isolates was compared for possible correlation. Result: 147 patients were diagnosed with nosocomial infections according to the CDC-NHSN criteria. The prevalence of enterobacteriaceae as nosocomial pathogens was found to be 45.57%. The most common hospital acquired infection was revealed to be urinary tract infection(61%), followed by ventilator associated pneumonia(19%). As far as the patient isolates are concerned, the most predominant bacteria was Klebsiella pneumoniae(61%) followed by Escherichia coli(34%).In the hospital environment, the predominant organism was Klebsiella pneumoniae(58%), followed by Enterobacter cloacae(25%) and Escherichia coli(17%). The tap was found to be a source of multidrug resistant Klebsiella pneumoniae. Conclusion: The hospital environment is a major source of multidrug resistant enterobacteriaceae.
Keywords: nosocomial infections, enterobacterales, high touch surfaces, hospital acquired, antibiogram, multidrug resistant organism.
