Introduction: SARS-CoV2 pandemic marks the need to pay attention bacterial pathogens that can complicate hospital stay of patients in intensive care unit (ICU). ESKAPE bacteria which includes Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter cloacae are considered most important, because their close relationship with development ventilator-associated pneumonia (VAP). The aim this work was identify...

Pyogenic liver abscesses (PLAs) are serious infections in which doctors often fail identifying the causative agent due to microbiological limitations. These limitations detecting uncommon pathogens complicate treatment and recovery. Molecular techniques, like massive sequencing, enable detection of highlight shortcomings traditional cultures. The aim this work was characterise bacterial composition PLAs through sequencing V3-V4 hypervariable region 16S rRNA gene cases where conventional...

Infertility, both primary and secondary, is strongly influenced by microbiological factors, with the vaginal microbiota playing a key role in reproductive health. The aim of this study was to characterize 136 Mexican women diagnosed infertility-primary (n = 58) secondary 78)-by evaluating presence pathogenic bacterial species their associations infertility conditions. Samples were obtained through cervical swabs, microorganism identification performed using qPCR techniques. Analysis revealed...

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has resulted in high mortality among hospitalized patients; thus, identifying markers treating these patients is essential. To evaluate the association between viral load and serum biomarkers with COVID-19. MATERIALS AND METHODS: A retrospective cohort study was conducted 198 inpatient records from a tertiary hospital Mexico City January April 2021. severe acute respiratory syndrome 2 (SARS-CoV-2) death due to COVID-19 assessed...

Manifestations of COVID-19 are diverse and range from asymptomatic to severe, critical illness death. Cases requiring hospital care (in severe illnesses) associated with comorbidities hyperactivation the immune system. Therefore, in this exploratory observational study, we analyzed which parameters mortality. We evaluated: demographic characteristics (age, sex comorbidities), laboratory data (albumin, leukocytes, lymphocytes, platelets, ferritin), days stay, interleukins (IL-2, IL-6, IL-7,...

One of the priority lines action to contain SARS-CoV-2 pandemic was vaccination programs for healthcare workers. However, with emergence highly contagious strains, such as Omicron variant, it necessary know serological status health personnel make decisions application reinforcements. The aim this work determine seroprevalence against in workers a Mexican hospital after six months administration Pfizer-BioNTech vaccine (two doses, 4 weeks apart) and investigate association between...

Introduction: Infections acquired in hospitals are the cause of high morbidity and mortality with emergence resistant bacteria, problem is greater. The aim this work was to determine genetic characteristics timeline Klebsiella pneumoniae blaNDM-1 carrying a class 1 integron involved an intrahospital outbreak.
 Methodology: Investigation made from first detection K. blaNDM-1, strain “466”, last clone “423”. 16S rRNA gene analysis showed that 466 clones were related pneumoniae....

ETV6::RUNX1 is a genetic rearrangement of good prognosis in children with acute lymphoblastic leukemia (ALL). In Mexico, its prevalence low comparison Caucasian populations. We developed novel TaqMan one-step RT-qPCR approach to assess the four rearrangements cohort Hispanic ALL from Mexico City. The common fusion gene transcripts was as follows: TCF3::PBX1 7.7%; BCR::ABL1p190 3.3%; and KMT2A::AFF1 2.8%, ETV6::RUNX1was observed (10.5%) that reported for countries. This consistent previous...

Background: The causative primary agent of urinary tract infections (UTI) is uropathogenic Escherichia coli (UPEC); however, commensal (CEC) has been also implicated in the development UTI. Due to recent emergence virulent and resistant strains, it necessary have evidence demonstrate that UPEC CEC are isolated from patients with UTI subsequently they genes be considered pathogenic. Objectives: To determine distribution resistance virulence strains (hospitalized ambulatory). Methods: One...

The course of kidney function and outcomes severe malaria infection in pregnant women is poorly understood. indications for renal replacement therapy patients with AKI are similar to the general population. This case a patient Plasmodium falciparum that caused cerebral malaria, acute injury (AKI) who required biopsy during her hospitalization. A 29-year-old woman from Equatorial Guinea was admitted hospital haemolytic anaemia, hyperbilirubinaemia thrombocytopenia. During hospitalization,...

Background: The current economic and social crisis in Latin America has caused migration to the USA, bringing with it Public Health challenges due importation of various infectious diseases. Migrants, particularly those chronic conditions, such as HIV infection other sexually transmitted infections (STI), are at greater risk pharmacological interruption access medical care, so timely detection diseases acquired during their migration, malaria, is crucial avoid health complications....

Brachybacterium conglomeratum, traditionally considered an environmental bacterium, has recently garnered attention for its potential involvement in human health. While prior research hinted at pathogenic role humans, our study aims to determine prevalence and associations diverse clinical contexts. We examined vaginal swabs from three distinct patient groups: patients with low-grade squamous intraepithelial lesions (LSIL), cervicovaginal infections, a history of precancerous undergoing...
