Summary
Poultry-associated Gram-negative bacteria exhibit significant antibiotic resistance. Over 70% of Salmonella, Escherichia, Pseudomonas, and Klebsiella strains showed resistance to common antibiotics, highlighting a critical public health concern.
Area of Science:
- Microbiology
- Veterinary Science
- Public Health
Background:
- Gram-negative bacteria are common pathogens in poultry.
- Antibiotic resistance in bacteria poses a significant threat to public health.
- Poultry can serve as a reservoir for antibiotic-resistant bacteria.
Purpose of the Study:
- To screen Gram-negative bacteria isolated from poultry for antibiotic resistance.
- To determine the prevalence of resistance to commonly used antibiotics in these bacteria.
Main Methods:
- Isolation and identification of Gram-negative bacteria (Salmonella, Escherichia, Pseudomonas, Klebsiella) from poultry.
- Screening bacterial isolates for resistance to ampicillin, chloramphenicol, gentamycin, kanamycin, neomycin, polymyxin B, streptomycin, and tetracycline at 50 µg/ml.
Main Results:
- Out of 500 bacterial isolates screened, 351 (70.2%) demonstrated resistance to at least one antibiotic.
- Multiple resistance patterns were observed among the resistant strains.
Conclusions:
- A high prevalence of antibiotic resistance exists in Gram-negative bacteria isolated from poultry.
- These findings underscore the need for monitoring antibiotic resistance in food-producing animals to mitigate public health risks.
