Abstract
The presence of antimicrobial-resistance genes (ARGs) in mobile genetic elements (MGEs) facilitates the rapid development and dissemination of multidrug-resistant bacteria, which represents a serious problem for human health. This is a One Health study which aims to investigate the co-occurrence of antimicrobial resistance determinants among clinical and environmental isolates of
K. pneumoniae
and
E. coli
. Various bioinformatics tools were used to elucidate the bacterial strains’ ID, resistome, virulome, MGEs, and phylogeny for 42 isolates obtained from hospitalized patients (
n
= 20) and environmental sites (including fresh vegetables, fruits, and drinking water) (
n
= 22). The multilocus sequence typing (MLST) showed that
K. pneumoniae
belonged to ten sequence types (STs) while the
E. coli
belonged to seventeen STs. Multidrug-resistant isolates harbored β-lactam, aminoglycoside resistance determinants, and MGE were detected circulating in the environment (drinking water, fresh vegetables, and fruits) and in patients hospitalized with postoperative infections, neonatal sepsis, and urinary tract infection. Four
K. pneumoniae
environmental isolates (7E, 16EE, 1KE, and 19KE) were multidrug-resistant and were positive for different beta-lactam and aminoglycoside resistance determinants.

CTX-M-15
in brackets of ISEc 9 and Tn 3 transposases was detected in isolates circulating in the pediatrics unit of Soba hospital and the environment. This study documented the presence of bacterial isolates harboring a similar pattern of antimicrobial resistance determinants circulating in hospitals and environments. A rapid response is needed from stakeholders to initiate a program for infection prevention and control measures to detect such clones disseminated in the communities and hospitals.
