Anti-Helicobacter pylori Activity of Quinolone Alkaloids from Evodiae Fructus.
, 1999 A biologically monitored fractionation of methanol extract of the fruit of Evodia rutaecarpa led to the isolation of six quinolone alkaloids, evocarpine (1), 1-methyl-2-[(4Z,7Z)-4,7-tridecadienyl]-4(1H)-quinolone (2), 1-methyl-2-[(6Z,9Z)-6,9 ...

How Host Phylogeny, Diet, and Habitat Affect Gut Microbial Diversity in Wild Snakes
Ecology and Evolution, Volume 16, Issue 7, July 2026.Gut microbiota plays critical roles in host digestion, immune regulation, neurochemical signaling, and metabolic homeostasis. Based on wild snakes (73 individuals from 23 species) from China, we explored the composition, characteristics, and functions of gut microbes across different groups using fecal metagenomic samples; further we explored the ...

Advances in immunoassay methods for quinolones
Shipin yu jixieQuinolones (QNs) are highly favored for their broad-spectrum antibacterial effects. However, the overuse of QNs in animal feed can lead to their residues entering the food chain, thus posing potential hazards to the environment and human health.

Trends in Enterobacteriaceae Resistance Patterns: A Nine‐Year Retrospective Study From North Lebanon
Health Science Reports, Volume 9, Issue 7, July 2026.ABSTRACT Background and Aims Antimicrobial resistance (AMR) in Enterobacteriaceae poses a critical threat to global health, particularly in regions where antibiotic misuse and limited surveillance prevail. Intensive care units (ICUs) act as focal points for resistance emergence and dissemination. This study aimed to evaluate long‐term resistance trends

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.The graphical abstract outlines that samples from milk, faeces and soil were tested for Enterococcus avium using culture, PCR and genome sequencing.2. Overall, prevalence of E. avium was 56.3%, and 93.5% of isolates were multidrug‐resistant.3. Genomic analysis revealed six ARGs, 43–45 VFGs and 4–6 bacteriocins.4.

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.Multidrug‐resistant Salmonella was detected in 13.5% of the raw meat samples in Chattogram, with resistance to multiple antibiotics and a high prevalence of the blaTEM gene. These findings highlight significant foodborne AMR risks and underscore the need for urgent One Health interventions to protect public health.
