Staphylococcus aureus en pollos de crianza en un criadero de Jadán -Ecuador diciembre 2022 - febrero 2023

Abstract

Introduction: The poultry industry, particularly poultry breeding, has witnessed exponential growth alongside the implementation of animal care practices that can potentially lead to cross-contamination with pathogenic microorganisms. One such microorganism is Staphylococcus aureus, a bacterium responsible for numerous diseases. Objective: This study aims to determine the frequency and antimicrobial susceptibility of Staphylococcus aureus isolated from the nares of broiler chickens in Jadan, Ecuador, between December 2022 and February 2023, using microbiological methods. Methodology: This is an observational, descriptive, cross-sectional study. The study population consists of isolates obtained from the nares of broiler chickens from a hatchery in Jadan, Ecuador. A non-probabilistic convenience sampling method was employed, resulting in 60 samples. Results: Biochemical tests identified twelve positive samples of S. aureus among the 60 isolated obtained from broiler breeding chicken nostrils. Furthermore, a high percentage of sensitivity to clindamycin, erythromycin, cefoxitin, and penicillin antibiotics was observed. Conclusion: The prevalence of S. aureus in broilers is relatively low (20%). Adequate antibiotic management practices are in place, leading to low resistance. Hygiene and cleanliness regulations are followed diligently to prevent bacterial spread.
