Unveiling the resistance: comparative genomic analysis of two novel cefiderocol-resistant Stenotrophomonas species from a Referral Hospital in Mexico City.

Background: Stenotrophomonas maltophilia is the species most frequently identified by clinical microbiology laboratories due to its presence in the main identification systems databases. Phenotypic identification methods are widely used in laboratories, and the misidentification of Stenotrophomonas spp. is highly probable due to the presence of cryptic species.

-Defensin conventional markers of inflammation in periprosthetic joint infection: a retrospective study.

Background: Diagnosing periprosthetic joint infection (PJI) remains a significant challenge for healthcare professionals. Commonly utilized inflammatory markers include erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and white blood cells (WBC). Human -defensin 1 (-defensin) is an antimicrobial peptide elevated in infection, yet its diagnostic value for PJI has not been explored.

Assessment of airborne bacteria from a public health institution in Mexico City.

In this work, the composition of the bacterial community in the air of a hospital in Mexico City was evaluated using metabarcoding and proteomics approaches, along with the assessment of environmental factors such as temperature, humidity, and suspended particles. Two types of aerobiological samplers were used: Andersen One-Stage Viable Particle Sampler (AVPS) and Coriolis μ sampler (CμS-Sampler). Sampling was performed in four areas of the hospital: Floor 1 (F1), Floor 2 (F2), and Emergency Unit (EU), as well as outdoors (OH).

Myroides species, pathogenic spectrum and clinical microbiology sight in Mexican isolates.

Introduction: Myroides is a bacterial genus of opportunistic bacteria responsible for diverse infections including in the skin and soft tissues, urinary tract, cardiovascular system, and bacteremia, although the incidence of its reported infections is low, it is increasing, likely due the use of better bacterial identification methods, but also perhaps due an increase in its prevalence. In addition, their pathogenic role is limited in terms of reporting their microbial physiology, so the present work provides information in this regard in addition to the information that is available in the international literature.

Objective: To describe the microbiological and genetic characteristics of seven different Myroides spp.

Inside-out, antimicrobial resistance mediated by efflux pumps in clinical strains of Acinetobacter baumannii isolated from burn wound infections.

Acinetobacter baumannii belongs to the ESKAPE group. It is classified as a critical priority group by the World Health Organization and a global concern on account of its capacity to acquire and develop resistance mechanisms to multiple antibiotics. Data from the United States indicates 500 deaths annually.

Acquired and Carbapenemase-Encoding Genes in : A Seven-Year Survey Highlighting an Increasing Epidemiological Threat.

(1) Background: is a Gram-negative bacterium with several intrinsic and acquired antimicrobial resistance mechanisms. The spread of carbapenemase-encoding genes, an acquired mechanism, enables carbapenem resistance in clinical settings. Detection of the carbapenemase-producer strains is urgent.

Comparison of Lateral Flow Immunochromatography and Phenotypic Assays to PCR for the Detection of Carbapenemase-Producing Gram-Negative Bacteria, a Multicenter Experience in Mexico.

The identification of carbapenemase-producing Enterobacterales and is important for treating and controlling hospital infections. The recommended methods for their identification require a long waiting time, technical training, and expertise. Lateral flow immunoassays such as NG-Test CARBA 5 overcome these needs.
