Abstract
- Avian pathogenic Escherichia coli (APEC) represents a major challenge for the poultry industry, causing significant economic losses. This problem is exacerbated by the misuse use of antibiotics in Veterinary Medicine, leading to the emergence of resistant strains and thus creating a significant risk to Public Health. This study, carried out on 38 poultry farms in Algeria, involved the collection of 200 samples for the isolation of E. coli strains. The resistance of these strains to frequently used antibiotics was assessed using the agar diffusion method. Multiple Correspondence Analysis (MCA) was used to determine potential risk factors. The obtained results revealed that E. coli was present in 30% of samples. Alarming levels of resistance were observed against Tetracycline (81.6%), Ampicillin (78.3%), Ciprofloxacin (68.3%) and Nalidixic acid (60%). Stressful environmental conditions in poultry houses, such as temperature variations, high humidity, poor ventilation and stocking density were identified as key factors in the development of avian colibacillosis. In conclusion, the current study highlights the urgent need to strictly monitor and regulate the use of antibiotics in Veterinary Medicine and improve animal welfare in order to minimize the risk it pose to Public Health originated in the farms. In addition, it is essential that farmers maintain optimal environmental conditions in chicken rearing.
