Hypothesis
The study aims to identify and characterize Cronobacter isolated from dried milk and related products available in an Egyptian food market.
Conclusion
The study identified the presence of Cronobacter in dried milk and related products sourced from the Nile-Delta region of Egypt, with some strains showing antibiotic resistance.
Supporting Evidence
- Sixteen Cronobacter strains were isolated from 152 dairy-based products.
- Three strains showed resistance to trimethoprim and/or neomycin.
- Pulsed-field gel electrophoresis identified 8 PFGE types among the strains.
Takeaway
Researchers found a type of bacteria called Cronobacter in dried milk products, which can make babies very sick. Some of these bacteria were resistant to antibiotics.
Methodology
The study involved isolating and characterizing Cronobacter strains from 152 dairy-based products using phenotyping, genotyping, and antibiotic susceptibility tests.
Limitations
The study focused only on dried milk and related products from a specific region, which may not represent the prevalence of Cronobacter in other food sources.
