As the globe faces a rise in antibiotic-resistant bacteria – making traditional antibiotics ineffective – specific viruses could offer a solution. Viruses called bacteriophages, or phages, target bacteria but can’t infect humans or other higher organisms. Phages inject their DNA into the…
Researchers from Zhejiang University, et al. have conducted a study entitled “Diversified antibiotic resistance and sensitivity patterns induced by quaternary ammonium compounds”. This study was published in Frontiers of Environmental Science & Engineering, Volume 19, Issue 8. Diversified Antibiotic Resistance and Sensitivity Patterns…
The findings, published Oct. 29 in Nature Microbiology, are a major milestone for the field of virology and redefine picobirnaviruses as only the third known family of bacteria-infecting RNA viruses ever discovered. This discovery changes our understanding of the gut ecosystem.
Worldwide, antibiotic resistance is associated with millions of deaths every year, and the World Health Organization warns that the number of resistant infections is rising. Amino acid restores power to last-resort antibiotics Worldwide, antibiotic resistance is associated with millions of…
The bactericide zhongshengmycin, used in Xinjiang for more than 30 years to control bacterial plant diseases, currently faces a low resistance risk from Erwinia amylovora, the pathogen behind pear fire blight. Fire blight is one of the most destructive bacterial diseases…
A systematic review of 27 studies maps how Gram-positive and Gram-negative bacteria use enzymes, thiols, metal homeostasis, and biofilm matrices to survive oxidative stress. Article Title: A systematic review of antioxidant defense mechanisms in bacteria species News Source: Drew Townsend. (October…
Researchers purified a heat-stable, proteinaceous antibacterial compound called PAM3-2 from a marine-derived Acinetobacter pittii strain, finding the strongest activity against Salmonella Paratyphi B. A proteinaceous antibacterial substance produced by a marine-derived strain of Acinetobacter pittii has been isolated and characterized in a…
The team profiled the vaginal microbiomes of pregnant ewes vaccinated with attenuated strains of Brucella melitensis, using 16S rRNA amplicon sequencing of the V3–V4 region. This approach reads the genetic barcodes of bacteria present in vaginal samples, allowing researchers to track both…
A new review reports that bacteria in biofilms can resist antibiotics up to 1,000 times more than planktonic cells, driving persistent infections that current antimicrobial strategies often fail to clear.
A Burkholderia strain isolated from Delhi's Yamuna River removed 68.9 percent of amoxicillin in a minimal medium within 14 days, with negligible loss in bacteria-free controls.
Superbugs and the fight against them: how antibiotic resistance spreads, resistance genes, the search for new antibiotics, and alternatives such as phages and antimicrobial peptides.
