GUERRERO-ENCINAS, Ildefonso et al. Bacterial resistance status at a level 2 hospital in Northwest Mexico in 2016. Biotecnia [online]. 2023, vol.25, n.3, pp.93-104.  Epub 27-Mayo-2024. ISSN 1665-1456.  https://doi.org/10.18633/biotecnia.v25i3.2046.

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 dangerous. 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 (HGE), Mexico so that it can be compared with future information and look for strategies to mitigate this problem. Information was collected from logs registered at the hospital microbiology area in 2016, on bacterial cultures with antibiograms from 2,205 biological samples. These data were obtained from the VITEK® system, which provided information on the bacteria spp., their antibiotic resistance, and the type of antibiotics to which were resistant. 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 HGE. These findings highlight the need for further research on antibiotic resistance in Mexico to design national prevention strategies.
