Isolation and determination antimicrobial susceptibility pattern of enterobacter amnigenus biogroup 1 strains isolated from consumed powdered infant formula milk in NICU ward
Background: Enterobacter amnigenus biogroup 1 is a non-sporeforming, rod-shaped, gram-negative bacterium, within the Enterobacteriaceae family. It is opportunistic pathogen and cause disease humans, especially in premature and immunocompromised persons. The aim of this study was to isolation and det...

It is opportunistic pathogen and cause disease humans, especially in premature and immunocompromised persons. The aim of this study was to isolation and determination antimicrobial susceptibility pattern of Enterobacter amnigenus biogroup 1 strains isolated from consumed powdered infant formula (PIF) milk in Neonatal Intensive Care Unit (NICU) ward. Materials and Methods : In this cross-sectional study, total 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 by using the standard disc diffusion method based on CLSI (2011) recommendations. Results: In this study, Enterobacter amnigenus biogroup 1 was isolated from 2 (1.6%) of 125 powdered infant formula milk samples. The results showed that isolated strains are sensitive to most antibiotics. All isolates were resistant to amoxicillin and carbenicillin. Conclusion: Contamination of powdered infant formula (PIF) samples could have occurred during different steps. It is imperative to prepare the powdered infant formula milk foods according to the manufacturer’s instruction and in an aseptic condition. Contamination of powdered infant formula only could be reduced or prevented by monitoring the critical control points and taking appropriate action during the processing.http://ismj.bpums.ac.ir/browse.php?a_code=A-10-3-560&slc_lang=en&sid=1Neonatal Intensive Care Unit (NICU) Powdered infant formula milk Enterobacter amnigenus biogroup 1 Antibiotical susceptibility. |
