Patrones de resistencia bacteriana en Staphylococcus spp de Medilab-Medihospital, Loja 2018- 2020

Bacterial resistance to antibiotics is one of the biggest public health problems worldwide, which makes it difficult to control infectious diseases caused by bacterial microorganisms since it generates therapeutic failure, lengthens treatments and increases costs in health care. The microorganism Staphylococcus spp, is one the of the most studied bacterial groups due to its clinical importance and the high rates of resistance it presents to antibiotics. The most important specie is Staphylococcus aureus, which is considered the most pathogenic, followed by coagulase-negative staphylococci that act as opportunistic pathogens. The following study is descriptive and cross-sectional, its objective is to determine bacterial resistance patterns of Staphylococcus spp from the antibiogram records carried out in the Medilab-Medihospital Clinical Laboratory from 2018 to 2020. In addition, 86 positive cultures were isolated for Staphylococcus spp, the studied showed that Staphylococcus aureus and Staphylococcus epidermidis are the most frequent in the outpatient area with 71.43% and 78.40% respectively with predominance in secretion samples with 77.6% and 67.6%. The resistance profile of Staphylococcus aureus against the antibiotics tested in the microbiology laboratory are the following: penicillin (87%), oxacillin (81.50%) and erythromycin (64.6%); while that of Staphylococcus epidermidis was: penicillin (75%), oxacillin (66.7%), erythromycin (62.9%), and clindamycin (52.8%). It is concluded that in both groups of microorganisms they express phenotypes of resistance to oxacillin, penicillin and erythromycin, besides sensitivity to vancomycin and linezolid and variable susceptibility to the rest of the antibiotics evaluated.
