The wide range of symptoms the coronavirus disease 2019 (COVID-19) makes it challenging to predict evolution using a single parameter. Therefore, describe pathophysiological response SARS-CoV-2 infection in hospitalized patients with severe COVID-19, we compared according survival or death, sociodemographic and clinical characteristics, biochemical immunological attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectra from saliva samples their correlation chemometric...
Background: Drug-resistant tuberculosis (TB) is associated with higher mortality rates in patients human immunodeficiency virus (HIV). In Mexico, the number of deaths due to TB among HIV-positive population has tripled recent years. Methods: Ninety-three Mycobacterium strains isolated from same HIV-infected treated a public hospital Mexico City were studied determine drug resistance first- and second-line anti-TB drugs identify mutations resistance. Results: Of 93 patients, 82.7% new cases,...
This study aimed to determine the bacteriological quality and presence of diarrheagenic Escherichia coli pathotypes (DEP) nontuberculous mycobacteria (NTM) species in 85 packaged ice samples from 12 different states central Mexico. Three had a pH 9.8 therefore fell outside acceptable range for pH. All were positive aerobic-mesophilic bacteria, with limits ranging 1 3.47 log CFU/mL. In total, 35, 11, 3 total coliforms (TC), fecal (FC), E. coli, respectively. samples, TC concentration ranged...
Abstract There is a growing trend in using saliva for SARS-CoV-2 detection with reasonable accuracy. We have studied the responses of IgA, IgG, and IgM human by directly comparing disease control analyzing two-trace two-dimensional correlation spectra (2T2D-COS) employing Fourier transform infrared (FTIR) spectra. The findings show decrease IgG salivary antibodies 50, 60, 65, 75-years samples. Among various COVID-19 populations studied, female 30 years group reveal defence mechanisms...
There has been very limited investigation regarding the genetic diversity of
The exponential increase in the number of cases COVID-19 and technical difficulties to obtain an RT-PCR result for SARS-CoV-2, according Berlin protocol, enabled migration manual PCR assay, validated by Instituto de Diagnóstico y Referencia Epidemiológicos (InDRE), BD Max system utilizing use reagents from open system. A total 48 clinical samples were taken patients who went emergency room with COVID features; 46 % (22/48) positive SARS-CoV-2. sensitivity automated MAX assay was 92% (20/22),...
Although the incidence of HIV-associated lung infections has changed due to use antiretrovirals, and knowledge contributions respiratory viruses, including subtypes seasonal human coronavirus (HCoV) increased, studies analyze compare prognosis risk factors between HIV-positive negative individuals with HCoV are scarce. Patients HIV at a higher getting infected various pathogens, therefore, it is important comprehend epidemiology these infections. This study aimed expose epidemiological...
