Abstract Background: This study aimed to detect the frequency of class1 and 2 and 3 integrons in vancomycin-resistant enterococcus (VRE) and aminoglycoside resistance strains isolated from burn patients in Taleghani burn hospital, AhvazResults: Out of the 129 Enterococcus species 42% were E. faecalis and 57% isolated were E. faecium. 34% were resistant to vancomycin. In the E. faecium isolates, 21% were XDR and 67%) were MDR. In the E. faecalis isolates, 74% were MDR isolates. Among 129 Enterococci spp. Isolates 45% E. faecium and 20% E. faecalis isolates were positive for the presence of vanA genes. In addition, 20% E. faecium and 0.04% E. faecalis isolates were positive for the presence of vanB genes. Thirty-one E Enterococci spp including E. faecium 79% and E. faecium 58% isolates carried int 1. In VRE E. faecalis 57.1% isolates positive for the presence of int 1and 57.1% isolates positive for the presence of int 1. Conclusion: we showed a detailed resistance pattern of clinically isolated Enterococci species to common antibiotics. Accordingly, the results confirmed the association between simultaneous resistance to vancomycin. These results can guide antibiotic prescriptions against Enterococci infections.

Conventional swine production evolved to routinely use antimicrobials, and common occurrence of antimicrobial-resistant Salmonella has been reported. There is a paucity of information on the antimicrobial resistance of Salmonella in swine production in the absence of antimicrobial selective pressure. Therefore, we compared the prevalence and antimicrobial resistance of Salmonella isolated from antimicrobial-free and conventional production systems. A total of 889 pigs and 743 carcasses were sampled in the study. Salmonella prevalence was significantly higher among the antimicrobial-free systems (15.2%) than the conventional systems (4.2%) (odds ratio [OR] = 4.23; P < 0.05). Antimicrobial resistance was detected against 10 of the 12 antimicrobials tested. The highest frequency of resistance was found against tetracycline (80%), followed by streptomycin (43.4%) and sulfamethoxazole (36%). Frequency of resistance to most classes of antimicrobials (except tetracycline) was significantly higher among conventional farms than antimicrobial-free farms, with ORs ranging from 2.84 for chloramphenicol to 23.22 for kanamycin at the on-farm level. A total of 28 antimicrobial resistance patterns were detected. A resistance pattern with streptomycin, sulfamethoxazole, and tetracycline (n = 130) was the most common multidrug resistance pattern. There was no significant difference in the proportion of isolates with this pattern between the conventional (19.5%) and the antimicrobial-free systems (18%) (OR = 1.8; P > 0.05). A pentaresistance pattern with ampicillin, chloramphenicol, streptomycin, sulfamethoxazole, and tetracycline was strongly associated with antimicrobial-free groups (OR = 5.4; P = 0.01). While showing the higher likelihood of finding antimicrobial resistance among conventional herds, this study also implies that specific multidrug-resistant strains may occur on antimicrobial-free farms. A longitudinal study with a representative sample size is needed to reach more conclusive results of the associations detected in this study.
