Objective: Staphylococcus aureus and Escherichia coli are the most common opportunistic patho¬gens frequently associated with respiratory tract infection (RTI) in different animals. This cross-sec¬tional study aimed to identify occurrence of S. E. goats RTI, analyze antimicrobial resistance patterns, explore potential risk factors contributing RTI. Materials Methods: A total 120 nasal swab samples were collected from goats, stan¬dard classical bacteriological methods performed isolate coli. Subsequently, disc diffusion method was employed evaluate sensitivity test. logistic regression model used Results: About 13.3% (N = 16; N 120) isolates confirmed as aureus, 6.67% 8; All resistant ampicillin, all amoxicillin penicillin. Among isolated organisms, 43.7% 7; 16) 62.5% 5; 8) found be multidrug-resistant (resistant ≥3 classes antimicrobials). Multivariable analysis revealed that female [(odds ratio) OR: 4.2; 95% confidence intervals (CI): 0.8–20.8; p 0.074] poor health condition (OR: 3.8; CI: 0.7–19.3; 0.100) more prone RTI caused by aureus. Besides, not dewormed 4.8; 1–23.6; 0.051) those reared semi-intensive conditions 2.7; 0.8–8.7; 0.092) at higher aureus-mediated Conclusion: The findings highlight importance implementing improved farm management practices efficient control approaches minimize infections reduce burden antibiotic goats.
