Antimicrobial resistance of bacteria isolated from powdered infant formulas (pif)‎

Abstract EN

A total of 65 samples of powdered infant formula (PIF) and dried infant cereals were collected at random from different specialties that are available in Hilla city /Iraq, during a 3-month period from October to December 2006.

The morphological and physiological characterization of bacterial isolates and antimicrobial susceptibility testing were performed.

Bacterial isolates were cultured from 53.8 % of 65 milk substitute infant formulas.

The concentration did not exceed a level of 10 CFU/g in any product.

The most commonly identified isolates were Bacillus subtilize Staphylococcus aurous, Klebsiella pneumoniae, Enterobacter cloacae, and Citrobacter freundii.One isolate of Enterobacter sakazaki, was also detected.

Antimicrobial susceptibility testing showed significant resistance rates, particularly to ampicillin, amoxicillin /clavulanic acid, cefotatxime, and gentamicin, but they were highly sensitive to ciprofloxacin and Refampin.
