Healthcare-associated infections (HAIs) are infections that occur while receiving health care, develop in a hospital or other healthcare facility, and first appear 48 hours or more after hospital admission, or within 30 days after having received health care. HAIs are linked to high mortality rates, prolonged stays, increased hospital overhead costs, and financial burdens on patients. Bacterial transmission from medical personnel or the environment, or patient-to-patient contact are all potential causes of these infections. A molecular epidemiology approach is needed to examine the contribution of risk factors and the distribution of "ESKAPE" pathogens within the hospital environment. In this study, we conducted a comprehensive analysis of the distribution of ESKAPE bacterial pathogens in the environment of pediatric intensive care units over a 30-day time interval using shotgun metagenomics. We collected samples from handwashing sinks, the floor around patients, and ventilator screens and tubes in the pediatric intensive care unit (PICU) of General Hospital, Yogyakarta, Indonesia in March 2022. We determine taxonomic profiles and also detect resistome, and virulome distribution of ESKAPE pathogens on various environmental surfaces through shotgun metagenomic sequencing. The microbiomes of the floor, sink, and mechanical ventilator exhibit a diverse composition of microbial communities, featuring significant species richness based on Shannon and Simpson’s index. These microbiomes encompass a wide array of microbial species, including ESKAPE bacterial pathogens, as well as profiles related to resistome and virulome. ESKAPE pathogens, especially Acinetobacter baumannii, predominated in the PICU environment. Most virulome have been associated with metabolism/nutrition and adhesion. Noteworthy findings include resistome genes characterized by mechanisms like efflux pumps (MDR) and alterations in antibiotic targets. |
