Prevalencia de staphylococcus aureus meticilino resistente y determinación de antibiótipo, en un periodo de tiempo comprendido entre Enero de 2010 y Octubre de 2017 en una institución pública de alta complejidad

In the last 10 years there has been an increase in the resistance of Staphylococcus aureus, which in turn endangers the effectiveness of antibiotic treatment thus becoming a public health problem. It has been described in the literature that this microorganism is the main cause of acquired bacteremia in the hospital environment as well as associated with the community and there are several risk factors that predispose patients to acquire such infection, such as hemodialysis, systemic infections. On the other hand, different methods are used to identify the resistance, among them the antibiogram, which takes as a parameter the minimum inhibitory concentration and the interpretation of this varies between sensitive, intermediate or resistant according to the points established by CSLI international standards. In the present study, the data provided by the microbiology laboratory of El Tunal Hospital were used, which were analyzed using the WHONET ® 5.6 software. According to this analysis of 1375 isolates from 2010 to 2017, it is evident that the highest prevalence of methicillin-resistant Staphylococcus aureus occurs in 2012 with a percentage of 52.1%. Regarding the antibiotics to which this microorganism is resistant, it was evidenced that the percentage of resistance to clindamycin is much higher compared to Trimethoprim / Sulfamethoxazole, with the highest percentages being 43.3% and 13.2% respectively. Another significant finding is the evidence of resistance to vancomycin in this group of patients, with a percentage of 5.9% in 2017, this being the highest.
