Deciphering mechanisms of < em > bla < /em > < sub > NDM < /sub > gene transmission between human and animals: a genomics study of bacterial isolates from various sources in China, 2015 to 2017
ConclusionThis study in a Chinese context suggests that cross-species transmission of certain STs of E. coli harbouring bla NDM on mobile elements, may facilitate the spread of carbapenem-resistant Enterobacteriaceae. Stringent monitoring of bla NDM-bearing E. coli in ecosystems is important.PMID:37707983 | DOI:10.2807/1560-7917.ES.2023.28.37.2200925

One-tube RPA-CRISPR Cas12a/Cas13a rapid detection of methicillin-resistant Staphylococcus aureus
Anal Chim Acta. 2023 Oct 16;1278:341757. doi: 10.1016/j.aca.2023.341757. Epub 2023 Aug 26.ABSTRACTAt present, methicillin-resistant Staphylococcus aureus (MRSA) has caused a serious impact on a global scale. The infection and carrier rate of MRSA in the community is increasing year by year, but there is still no convenient detection system for on-site rapid detection. It is very important to select a rapid detection system to accurately and quickly detect patients infected with MRSA. We have developed a high-efficient single-tube detection platform based on RPA and CRISPR reaction system to detect the genes of mecA and clf...

Photo-Electro-Biochemical H2 Production Using the Carbon Material-Based Cathode Combined with Genetically Engineered Escherichia coli Whole-Cell Biocatalysis
This study constructed a H2-forming biocathode based on a carbon material combined with whole-cell biocatalysis of genetically-engineered-hydrogenase-overproducing Escherichia coli for the photoelectrochemical water splitting for clean H2 production. Low-cost and abundant carbon materials are generally not suitable for H2-forming cathode due to their high overpotential for proton reduction; however, the combination of the reduction of an organic electron mediator on the carbon electrode and the H2 formation with the reduced mediator by the redox enzyme hydrogenase provides a H2-forming cathodic reaction comparable to that ...

Time evolution of electrical impedance spectra of Staphylococcus aureus and Escherichia coli bacteria
Bioelectrochemistry. 2023 Sep 9;155:108557. doi: 10.1016/j.bioelechem.2023.108557. Online ahead of print.ABSTRACTThis research work reports the time evolution of the electrical properties of gram-positive and gram-negative bacteria in aqueous suspensions with methyl violet and Lugol; measurements of galvanostatic electrical impedance spectra were made in a frequency range of 10Hz to 100kHz. The magnitude of the impedance as a function of frequency for methicillin-resistant strains, Staphylococcus aureus (gram-positive), and Escherichia coli O157: H7 (gram-negative) in the presence of methyl violet and Lugol, showed that bo...

Phenotypic and genotypic characterizations of bacteria isolated from the respiratory microbiota of healthy turkeys with potential for probiotic composition
AbstractDesirable characteristics ofStaphylococcus sp.,Streptococcus sp.,Bacillus sp.,Klebsiella sp.,Escherichia coli, andPseudomonas pseudoalcaligenes isolated from the trachea of healthy turkeys were evaluated as probiotic candidates in the search for new alternatives to solve antimicrobial resistance issues in poultry. In current study phenotypic and genotypic capacity to produce bacteriocin-like substances, efficacy to inhibit the growth of avian pathogens, susceptibility to antimicrobials of bacteria isolated from the respiratory microbiota of healthy turkeys, and the presence of virulence-associated genes (VAGs) pred...

Dissemination of IncI plasmid encoding < em > bla < /em > < sub > CTX-M-1 < /sub > is not hampered by its fitness cost in the pig's gut
Antimicrob Agents Chemother. 2023 Sep 13:e0011123. doi: 10.1128/aac.00111-23. Online ahead of print.ABSTRACTMultiresistance plasmids belonging to the IncI incompatibility group have become one of the most pervasive plasmid types in extended-spectrum beta-lactamase-producing Escherichia coli of animal origin. The extent of the burden imposed on the bacterial cell by these plasmids seems to modulate the emergence of "epidemic" plasmids. However, in vivo data in the natural environment of the strains are scarce. Here, we investigated the cost of a blaCTX-M-1-IncI1 epidemic plasmid in a commensal E. coli animal strain, UB12-RC...

Effectiveness of cefmetazole versus meropenem for invasive urinary tract infections caused by extended-spectrum β-lactamase-producing < em > Escherichia coli < /em >
Antimicrob Agents Chemother. 2023 Sep 13:e0051023. doi: 10.1128/aac.00510-23. Online ahead of print.ABSTRACTCefmetazole is active against extended-spectrum β-lactamase-producing Escherichia coli (ESBLEC) and is a potential candidate for carbapenem-sparing therapy. This multicenter, observational study included patients hospitalized for invasive urinary tract infection due to ESBLEC between March 2020 and November 2021 at 10 facilities in Japan, for whom either cefmetazole or meropenem was initiated as a definitive therapy within 96 h of culture collection and continued for at least 3 d. Outcomes included clinical and micr...
