Hypothesis
What are the antimicrobial resistance patterns of Salmonella Enteritidis isolates in southern Italy from 1990 to 1998?
Conclusion
A small proportion of Salmonella Enteritidis strains showed resistance to antibiotics, with some strains producing extended-spectrum beta-lactamases.
Supporting Evidence
- From 1990 to 1998, 1,889 strains of Salmonella Enteritidis were analyzed.
- 2.2% of the strains tested were resistant to at least one antibiotic.
- Resistance to ampicillin and tetracycline was commonly encountered.
- Six ESBL-producing isolates were identified from community-acquired enteritis cases.
- Resistance patterns were similar to those found in other European countries.
- Active monitoring of resistance is crucial for public health.
Takeaway
This study looked at how some germs that make people sick are becoming harder to treat with medicine. They found a few germs that can resist medicine, which is a problem.
Methodology
A retrospective study analyzing antimicrobial resistance patterns of Salmonella Enteritidis isolates from various sources over nine years.
Limitations
The study did not investigate temporal trends or associations with sources due to the rarity of resistant strains.
Participant Demographics
86% of the strains were of human origin, with the remainder from animals, sewage, and food.
