The objective of this research work was to identify the main bacteria with pathogenic potential isolated from the stethoscopes of veterinarians in the district of Trujillo and to identify the factors associated with the presence of these pathogens, by means of microbiological analysis and the application of a questionnaire. Fifty-nine stethoscopes (ear tips and chest pieces) from veterinary centers were sampled, and the veterinary doctors who used the stethoscopes and agreed to participate in the research work were surveyed, excluding those veterinary centers that did not have a stethoscope at the time of the visit or that did not have one at the time of the visit or that were found to be useless. The method used for sample collection, preservation and transport was adapted from the Technical Guide on Criteria and Procedures for the Microbiological Examination of Inert Surfaces, written by the General Directorate of Health (2006). On the other hand, for the isolation and identification of bacteria, standard bacteriological diagnostic procedures were adapted from the National Institute of Health (2005). The statistical analysis of the data was performed by applying Fisher's exact test of the SPSS version 25 software to determine the association between the independent variables and the presence of pathogenic bacteria in the sampled stethoscopes. As a result, of the 59 stethoscopes sampled, 88% were found to be contaminated, obtaining a total of 100 isolates, of which Staphylococcus aureus (35%) was the most isolated bacterial species, followed by Coagulase Negative Staphylococcus (34%), Pseudomonas spp. (18%) and others (13%). On the other hand, the surface with the highest frequency of bacteria was the thoracic piece with 71% (42/59). Of a total of 18 stethoscopes disinfected, 83% used 70° alcohol. Regarding the associated factors, a statistical association was determined between the variable disinfection and bacterial presence (p<0.05), and it was also demonstrated that non-disinfection is a risk factor for the presence of bacteria with pathogenic potential (OR= 1.636; 95%CI=1.132-2.366). Based on the above, it was concluded that Staphylococcus aureus is the bacterial agent with the highest prevalence in the thoracic part of the stethoscopes.
