ESKAPE and Beyond: The Burden of Coinfections in the COVID-19 Pandemic. Pathogens 2023; 12:pathogens12050743. [PMID: 37242413 DOI: 10.3390/pathogens12050743] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Revised: 05/15/2023] [Accepted: 05/18/2023] [Indexed: 05/28/2023] Open
Abstract
The ESKAPE group constitute a threat to public health, since these microorganisms are associated with severe infections in hospitals and have a direct relationship with high mortality rates. The presence of these bacteria in hospitals had a direct impact on the incidence of healthcare-associated coinfections in the SARS-CoV-2 pandemic. In recent years, these pathogens have shown resistance to multiple antibiotic families. The presence of high-risk clones within this group of bacteria contributes to the spread of resistance mechanisms worldwide. In the pandemic, these pathogens were implicated in coinfections in severely ill COVID-19 patients. The aim of this review is to describe the main microorganisms of the ESKAPE group involved in coinfections in COVID-19 patients, addressing mainly antimicrobial resistance mechanisms, epidemiology, and high-risk clones.

Detection of capsular genotypes of methicillin-resistant Staphylococcus aureus and clonal distribution of the cap5 and cap8 genes in clinical isolates. Arch Microbiol 2022; 204:186. [PMID: 35192046 PMCID: PMC8861481 DOI: 10.1007/s00203-022-02793-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2022] [Revised: 01/22/2022] [Accepted: 02/03/2022] [Indexed: 11/29/2022]
Abstract
Up until now, the capsular polysaccharides of Staphylococcus aureus have been classified into 11 types, of which only 2 types 5 and 8; (encoded by the genes cap5 and cap8, respectively) are present in 80–90% of clinically significant strains. The aim of the present study was to detect the capsular genotypes of methicillin-resistant S. aureus (MRSA) clinical isolates and determined their clonal distribution. A total of 262 MRSA clinical isolates from different hospitals in Mexico were analyzed by PCR to determine the genetic characteristics of their capsule expression. Pulsed-field gel electrophoresis and multilocus sequence typing were used to characterize the isolates. The analysis of the capsular genotypes among MRSA isolates showed that 245 isolates (93.5%) contained the cap5 gene, and that the remaining 17 (6.5%) encoded the cap8 gene. The MRSA isolates were grouped into four clonal groups. The identification of the capsular genotypes of clinical isolates of MRSA is important information because potential vaccine formulations against S. aureus involve capsular polysaccharides.

Abstract
This study evaluated the antimicrobial activity of Estericide(®) QX (super oxidized solution) in 524 bacterial clinical isolates causing nosocomial infections. The minimum inhibitory concentration (MIC) was determined by the serial broth microdilution method. The bacterial viability of the isolates and control strains was tested. The bactericidal effect of the disinfectant was determined according to the European Standards (EN) Test Methods-1040 guidelines. Assay of stability in Estericide QX after 1 year of storage was performed. The microdilution assays showed that the isolates were inhibited at concentrations of 10-40 parts per million (ppm). For gram-positive bacteria, the MIC values 20 and 40 ppm were more predominant (95%), whereas for gram-negative bacteria, the MIC values 10 and 20 ppm had the highest percentage (91.7%). The difference between the two groups was statistically significant (p<0.001). The results of the assay of bactericidal activity showed that all tested bacteria (99.999%) were killed within 30 sec of contact time. The stability test showed that Estericide QX maintained its disinfectant action over time. In conclusion, the results of the present study showed that the super oxidized solution of Estericide QX provides a high antibacterial activity on both gram-positive and gram-negative bacteria. Based on these results and under the conditions of the present study, we believe that Estericide QX can be used efficiently against multiresistant nosocomial bacteria, providing an opportunity for new disinfection alternatives.

Surveillance of methicillin-resistant Staphylococcus aureus causing nosocomial infections in five medical centers of Monterrey, Nuevo León, México from 2005-2009. Arch Med Res 2013; 44:570-4. [PMID: 24051038 DOI: 10.1016/j.arcmed.2013.09.001] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2013] [Accepted: 08/23/2013] [Indexed: 11/23/2022]
Abstract
BACKGROUND AND AIMS Staphylococcus aureus is a principal cause of human bacterial infection worldwide. The dissemination of antibiotic resistance among S. aureus strains is very import in the treatment of Staphylococcal infections. We undertook this study to identify methicillin-resistant Staphylococcus aureus (MRSA) clones responsible for nosocomial infection in five medical centers in Monterrey, Nuevo León (N.L.), México from 2005-2009. METHODS One hundred ninety MRSA strains collected from 2005-2009 from five hospitals affiliated with the Instituto Mexicano del Seguro Social (IMSS) in Monterrey, N.L., México were characterized by antimicrobial susceptibility, pulsed field gel electrophoresis (PFGE) and Staphylococcal Cassette Chromosome mec (SCCmec) typing. RESULTS Only one clone was present in the five hospitals (clone C); this clone is strongly associated with the New York-Japan clone (SCCmec II) with a broad resistance profile. CONCLUSIONS This study clearly documented the high ability for dissemination and the persistence of the New York-Japan clone in these centers.
