Background: Multidrug resistance (MDR) in Enterobacter spp. has created therapeutic challenges all over the world. The present study was conducted for evaluating the prevalence of class I integron, determining the gene cassettes and antimicrobial resistance profile of Enterobacter spp. isolates from clinical samples in Babol, North of Iran.
Methods: During a 13-month period, 30 Enterobacter spp. isolates were collected from Ayatollah Rouhani Hospital, Babol, Iran. Various types of antimicrobial agents were used to determine the resistance pattern. Class I integron and associated gene cassettes were detected by PCR assay.
Results: The resistance rates to AP, CPM, CTX, TM, NI, IMI, AK, CIP and GM antimicrobials were 100%, 93.3%, 33.3%, 33.3%, 30%, 20%, 20%, 20% and 13.3%, respectively. The distribution results of int genes showed that 63.3% of isolates carried the intI genes. Also, the prevalence of aadB, dfrA1, blaOXA30 and blaPSE1 genes were estimated at 36.6%%, 33.3%, 6.6% and 0%, respectively.
Conclusion: Our results showed that class I integrons have a widespread distribution among the Enterobacter spp. isolates and have clinical relevance to MDR isolates. The results confirmed the necessity for uninterrupted monitoring to prevent distribution of multidrug resistance among Enterobacter spp. strains in Iran |
