Active Surveillance of Antimicrobial Resistance and Carbapenemase-Encoding Genes According to Sites of Care and Age Groups in Mexico: Results from the INVIFAR Network.

We analyzed the antimicrobial resistance (AMR) data of 6519 clinical isolates of ( = 3985), ( = 775), ( = 163), ( = 781), ( = 124), and ( = 691) from 43 centers in Mexico. AMR assays were performed using commercial microdilution systems (37/43) and the disk diffusion susceptibility method (6/43). The presence of carbapenemase-encoding genes was assessed using PCR.

Drug resistance phenotypes and genotypes in Mexico in representative gram-negative species: Results from the infivar network.

Aim: This report presents phenotypic and genetic data on the prevalence and characteristics of extended-spectrum β-lactamases (ESBLs) and representative carbapenemases-producing Gram-negative species in Mexico.

Material And Methods: A total of 52 centers participated, 43 hospital-based laboratories and 9 external laboratories. The distribution of antimicrobial resistance data for Escherichia coli, Klebsiella pneumoniae, Enterobacter cloacae complex, Acinetobacter baumannii complex, and Pseudomonas aeruginosa in selected clinical specimens from January 1 to March 31, 2020 was analyzed using the WHONET 5.

Influenza challenging the diagnosis and management of pulmonary coccidioidomycosis.

Lower respiratory infections are the most important cause of death due to a transmissible disease. We present a case of severe influenza and coccidioidomycosis lung coinfection in a 65-year-old Mexican migrant. This case highlights the challenges that respiratory viruses impose on the diagnosis of fungal infections and on the multidisciplinary management of these infections.

The Evolution of Antimicrobial Resistance in Mexico During the Last Decade: Results from the INVIFAR Group.

Surveillance of antimicrobial resistance (AMR) requires an international approach with national and local strategies. Our aim was to summarize a retrospective 10-year report of antibiotic resistance of gram-positive and gram-negative bacteria in Mexico. A total of 46 centers from 22 states of Mexico participated.
