Characterization of Multiple Resistance Genes of Escherichia coli Strains Isolated from Food and Clinical Samples
Cell Mol Biol (Noisy-le-grand). 2023 Jul 31;69(7):118-126. doi: 10.14715/cmb/2023.69.7.19.ABSTRACTMulti-drug resistance (MDR), which is formed by the development of antimicrobial resistance, which is one of the defense mechanisms in bacteria, has pushed human beings to constantly seek new antimicrobial agents in the fight against these microorganisms. Speed and precision are very important in identifying resistance in strains with MDR that reach humans in an open system through the consumption of contaminated food or water. The main aim of this study was the molecular characterization of ESBL gene variants (blaTEM, blaOXA,...

Vaginal Microbiota Profile in first-trimester miscarriages cases
In this study, 435 vaginal swabs were collected from aborted women in Maternity Teaching Hospitals in Erbil and Shahid Dr. Khalid Hospital in Koya. We characterized the vaginal microbiota diversity and composition in first-trimester abortion and investigated the association between bacterial vaginosis and abortion before 12 weeks. Cultural, morphological, and biochemical characteristics for each bacterial genus were discovered, and VITEK-2 system was used to identify isolated bacteria. Samples from each type of bacteria were selected for sequencing utilizing 16 rRNA genes examining V4-V8 region for bacterial profiles. Bact...

Changes of Gut Microbiota in Maintenance Hemodialysis Patients and Their Impact on Patient's Microinflammation Status
In conclusion, patients with maintenance hemodialysis for CKD commonly exhibit gut microbiota dysbiosis and varying degrees of low-grade inflammation. Compared to healthy individuals, maintenance hemodialysis patients with CKD have lower levels of Bifidobacterium and Lactobacillus and higher levels of Escherichia coli and Enterococcus in their gut. Bifidobacterium, Lactobacillus, Escherichia coli, and Enterococcus all have a certain impact on the low-grade inflammation status of patients with maintenance hemodialysis for CKD.PMID:37715414 | DOI:10.14715/cmb/2023.69.8.15

High-throughput sequencing analysis of the characteristics of the gut microbiota in aged patients with sarcopenia
CONCLUSIONS: In this study, we have identified changes in the gut microbiota of sarcopenic individuals, which were linked to the loss of muscle mass and function. Escherichia-Shigella is a conditional pathogen of sarcopenic patients, and its levels are found to have a significant negative correlation with muscle mass.PMID:37716483 | DOI:10.1016/j.exger.2023.112287

Recent advances in the metabolic engineering and physiological opportunities for microbial synthesis of L-aspartic acid family amino acids: A review
Int J Biol Macromol. 2023 Sep 14:126916. doi: 10.1016/j.ijbiomac.2023.126916. Online ahead of print.ABSTRACTL-aspartic acid, L-threonine, L-isoleucine, l-lysine, and L-methionine constitute the l-aspartate amino acids (AFAAs). Except for L-aspartic acid, these are essential amino acids that cannot be synthesized by humans or animals themselves. E. coli and C. glutamicum are the main model organisms for AFAA production. It is necessary to reconstitute microbial cell factories and the physiological state of industrial fermentation cells for in-depth research into strains with higher AFAA production levels and optimal growth ...

The influence of Leucidal - eco-preservative from radish - on model lipid membranes and selected pathogenic bacteria
Chem Phys Lipids. 2023 Sep 14:105338. doi: 10.1016/j.chemphyslip.2023.105338. Online ahead of print.ABSTRACTIn this work the effect of Leucidal - a natural preservative from radish dedicated to be used in cosmetics - on bacteria cells and model bacteria membranes was investigated. To get insight into the mechanism of action of this formulation the lipid Langmuir monolayers imitating Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) membranes were prepared. Then, the influence of Leucidal on model systems was investigated by means of the surface pressure/area measurements, penetration studies and Brewster Ang...

A Campylobacteriosis Outbreak Caused by One Asymptomatic Food Handler Carrier
Biomed Environ Sci. 2023 Aug 20;36(8):779-782. doi: 10.3967/bes2023.105.ABSTRACTIn August 2021, three students with diarrhea from the same school visited a local hospital in the S district of Beijing. An epidemic investigation showed that there were more students with diarrhea in the same school and they had one meal together. Campylobacter jejuni was isolated from both patients with diarrhea and asymptomatic food handlers; however, the latter also carried Campylobacter coli. Phylogenomic analysis showed that there was a campylobacteriosis outbreak among the students, and the asymptomatic food handler may have been the sou...
