Bacterial resistance status in a level 2 hospital in Northwest Mexico in 2016

Abstract

Bacterial infections can be serious and require antibiotic treatment. However, the overuse of antibiotics has led to the development of antibacterial resistance, which can make infections more difficult to treat. This is a serious problem in Mexico, where published research on antibiotic resistance is limited. This study aimed to estimate the prevalence of antibiotic resistance in bacterial infections at the Hospital General del Estado in Hermosillo, Mexico. Information was collected from 2,205 biological samples registered in logs belonging to the hospital microbiology area, on bacterial cultures with antibiograms from patient samples. These data were obtained from the VITEK system, which provided information for the identification of the bacteria, their resistance, and sensitivity to antibiotics. Escherichia coli (28.8 %), Staphylococcus aureus (11.5 %), and Pseudomonas aeruginosa (9.8 %) were the most isolated bacteria. The highest prevalence of resistance was found against beta-lactam antibiotics. This study revealed that antibiotic resistance is a serious problem at the Hospital General del Estado. These findings highlight the need for further research and publishing information on antibiotic resistance in Mexico to design or redesign strategies to prevent and control this problem.
