Las Unidades Móviles Quirúrgicas (UMQ) son empleadas para procedimientos quirúrgicos de esterilización canina y felina en zonas vulnerables de la ciudad de Bogotá, Colombia, ampliando el acceso a estos servicios quirúrgicos veterinarios. Staphylococcus aureus meticilino-resistente (MRSA) es un patógeno de importancia en medicina veterinaria por su capacidad de causar morbilidad y mortalidad en animales, además de su potencial zoonótico. Este estudio buscó determinar la prevalencia de MRSA en guantes de cirujanos de las UMQ durante las jornadas de esterilización en Bogotá durante mayo de 2024. Se diligenció una encuesta y se obtuvieron hisopados de la porción interna (palma) e interdigital a los guantes de los cirujanos cada 5 animales intervenidos en 10 jornadas de esterilización de diferentes localidades de Bogotá. Las muestras se procesaron microbiológicamente utilizando medios enriquecidos, selectivos y diferenciales como
el CHROMagar MRSA. Los datos se registraron en una base de datos en Excel y se realizó un análisis estadístico de chi-cuadrado por medio del programa RSTUDIO, el cual permitió evaluar la asociación entre la presencia de MRSA y factores como tipo de población (canina o felina), estrato socioeconómico, sexo del cirujano y cambio de guantes entre procedimientos. Los resultados indicaron una prevalencia de MRSA del 20% en la población analizada. No se evidenciaron correlaciones significativas entre la presencia de MRSA y las variables estudiadas.
Mobile Surgical Units (MSUs) facilitate canine and feline sterilization in vulnerable areas of Bogotá, Colombia, expanding access to veterinary surgical services. Methicillinresistant Staphylococcus aureus (MRSA) is a significant veterinary pathogen due to its role in animal morbidity and mortality, as well as its zoonotic potential. This study aimed to determine MRSA prevalence on surgeons’ gloves during MSU sterilization campaigns in Bogotá in May 2024. A survey was administered, and swab samples were collected from the internal (palmar) and interdigital glove surfaces after every five animals treated across 10 sterilization campaigns in different Bogotá localities. Samples were microbiologically processed using enriched, selective, and differential media, including CHROMagar MRSA. Data were recorded in an Excel database and analyzed using a chi-square test in RStudio to assess associations between MRSA presence and factors such as animal type (canine or feline), socioeconomic stratum, surgeon’s sex, and glove changes between procedures. The results indicated a 20% MRSA prevalence, with no significant correlations observed between MRSA presence and the studied variables.
