Detección de bacterias patógenas Gram positivas presentes en los cubículos pertenecientes a los docentes de la facultad de ciencias de salud y facultad de ciencias exactas

Abstract

Abstract: Inanimate surfaces act as reservoirs for a variety of pathogenic microorganisms, facilitating the transmission of infections at the community and hospital levels. Furthermore, antimicrobial resistance has become a current public health problem. Objective: To identify the presence of Gram-positive pathogenic microorganisms in the cubicles used by faculty members of the Faculty of Health Sciences and Exact Sciences. Materials and methods: 155 samples were collected from inanimate surfaces by swabbing, and phenotypic and antibiotic susceptibility tests were performed. Results: From 155 sampled surfaces, 125 Gram-positive isolates were obtained, predominantly from the genus Staphylococcus (38.6%), with antibiotic susceptibility profiles resistant to Clarithromycin (27.9%), Cefoxitin (24.4%), Clindamycin (17.8%), Gentamicin (13.7%), Ampicillin (5.6%), Tetracycline (4.1%), Ciprofloxacin (3.6%), and Linezolid (3.0%). Conclusions. The results show the presence of Bacilli, Staphylococci, Streptococci, and Enterococci on the desks of faculty members belonging to the Faculty of Health Sciences, Exact and Natural Sciences of the Universidad Técnica Particular de Loja, with a higher pattern of moderate resistance to Clarithromycin, Cefoxitin, and Gentamicin, suggesting the need to implement more rigorous hygiene measures and practices.
