ABSTRACT

Background and Aim: Bats are a reservoir for the pathogenic bacteria Klebsiella pneumoniae and can spread it through feces that fall in nests/caves, carried, and dropped while they fly near human settlements, and from their saliva. The emergence and spread of multidrug resistance (MDR) strains of K. pneumoniae indicate that resistant to antibiotics, especially extended-spectrum beta-lactamase (ESBL), is considered an important global health threat. The aim of this study was to determine the presence of the gene encoding extended beta-lactamase in K. pneumoniae isolated from fresh bat feces collected from the Tanjung Ringgit bat cave, East Lombok.

Materials and Methods: In this study, 150 fresh fecal samples were analyzed using standard microbiological techniques for the presence of K. pneumoniae. K. pneumoniae-positive isolates were subjected to antibiotic sensitivity testing, followed by molecular detection using polymerase chain reaction.

Results: This study showed that 14 (9.3%) of 150 samples were positive for K. pneumoniae. Ten of the 14 samples (71.4%) were MDR isolates and 6 (42.9%) had the blaSHV gene identified.

Conclusion: The presence of K. pneumoniae isolated from fresh bat feces, which is MDR and has the blaSHV gene encoding ESBL indicates that bats can be a reservoir for the transmission of MDR and ESBL bacteria has an impact on public health in the study area.
