Prevalence and drug resistance pattern of Listeria monocytogenes among pregnant women in Tigray region, Northern Ethiopia: a cross-sectional study

Abstract

Abstract Objective The aim of this study was to determine the prevalence and antimicrobial susceptibility test of Listeria monocytogenes among pregnant women in Tigray region, Ethiopia. Results The overall prevalence of L. monocytogenes among pregnant women was found to be (8.5%; 12/141). With regard to the socio-demographic characteristics, a high prevalence of L. monocytogenes was observed in the age group of 20–24 years (18.6%; 8/43), rural dwellers (10%; 3/30), secondary school (9.6%; 5/52), and housewives (11.4%;10/88). A high drug resistance rate was observed to penicillin G (66.7%), clindamycin (66.7%), amoxicillin (50%) and vancomycin (50%). However, isolates were relatively sensitive to ciprofloxacin (75%), erythromycin (75%), trimethoprim/sulphamethaxazole (66.7%) and chloramphenicol (60%).
