Background: This research aimed to estimate the prevalence of extended-spectrum b-lactamase-producing Enterobacteriaceae (ESBL-PE) in stool samples of patients with different types of cancer. Materials and Methods: Stool samples or deep rectal swabs were collected from cancer cases from January 2017 to December 2018. After species identification, in order to detect ESBL-PE, double-disk synergy test (DD test) was used. Disk diffusion procedure was conducted to determine the susceptibility of bacteria to antimicrobials. Lastly, antibiotic resistance genes including bla genes were characterized via polymerase chain reaction (PCR). Findings: Among 100 patients enrolled in this study, 50 (50%) were ESBL carriers. Escherichia coli was the most prevalent bacterium isolated (85%). Genotyping of EBSL-PE encoding genes using PCR showed that the prevalence rates of bla CTX-M and bla CTX-M-15 genes were 94 (47 of 50) and 90% (45 of 50), respectively, which were higher than those of bla TEM (80%, 40 of 50) and bla SHV genes (34%, 17of 50). There was no significant association between ESBL-PE fecal carriage and age (p= .68), sex (p = .49), time of diagnosis (p= .21), antibiotic therapy for the past three months (p= .77), and history of chemotherapy (p= .49). Finally, it was determined that cancer type was an associated risk factor for ESBL-PE fecal carriage in cancer patients. Conclusion: This research emphasizes regular bacterial monitoring, and that antibiotic stewardship plans ought to be performed among cancer patients to prohibit further spread of ESBL-PE with confined therapeutic options.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
