Antibiotic Resistance and Occurrence of Class 1 Integrons in Clinical Isolates of Salmonella enterica

Abstract

Screening of non-typhoidal Salmonella enterica clinical isolates (n=20) by PCR revealed the high prevalence of class 1 integrons (45%). Multidrug-resistant (MDR) phenotypes were observed in all integron-positive isolates, regardless of the serotype. A significant correlation was found between the MDR phenotype and the presence of class 1 integrons in the isolates, especially in S. Typhimurium.

The Relationship Between Class I and II Integrons and Antibiotic Resistance Among Escherichia coli Isolates From Urinary Tract Infections

“…14 In this study, class II integron was detected in 21% of the isolates. Previous data confirmed that this class had a lower prevalence.…”
