Background: Enterobacter cloacae is a rod-shaped, gram-negative bacillus, from the family of Enterobacteriaceae. It is an opportunistic pathogen and causes disease in plants and humans (premature and immunocompromised persons of all age groups). The goal of this study was to isolate and determine antimicrobial susceptibility pattern of Enterobacter cloacae strains isolated from consumed powdered infant formula (PIF) milk in Neonatal Intensive Care Unit (NICU) ward. Material and Methods: In this cross-sectional study, a total of 125 consumed powdered infant formula milk in NICU ward were surveyed. Isolation and Identification of microorganisms was carried out according to FDA method. Antimicrobial susceptibility test was performed using the standard disc diffusion method based on CLSI (2011) recommendations. Results: Enterobacter cloacae was isolated from 2 (1.6%) of 125 PIF milk samples. The results showed that isolated strains are sensitive to most antibiotics. All isolates were resistant to amoxicillin. Conclusion: Since the infant formula (PIF) samples are unsterile products and contamination could occure during different steps, it is imperative to prepare the infant formula milk foods according to the manufacturer’s instruction and in an aseptic condition. Contamination of PIF only could be reduced or prevented by monitoring the critical control points and taking appropriate action during the processing.

Keywords: Neonatal Intensive Care Unit (NICU), powdered infant formula milk, Enterobacter cloacae, antimicrobial susceptibility.
