Antibacterial nanoagents with broad-spectrum antibacterial activities have emerged as an evolution of antibiotics. However, their bacteria-capturing capability and bacteria-killing efficiency remain insufficient for commercial implementation. Inspired by the hunting behavior spiders, here, a novel spiderweb-like nanoagent based on silver-adenine nanowires is designed to achieve high-efficiency ...

Antibiotic-resistant (ABR) bacteria develop when bacteria are exposed to antibiotics either during treatments in humans or animals or through environmental sources contaminated with antibiotic residues. Resistant bacteria selected by medical, agricultural, and industrial use spread globally through international travel, the export of animals and retail products, and the environment. It is essen...

Antimicrobials are heavily used in Chilean salmon aquaculture. We previously found significant differences in antimicrobial-resistant bacteria between sediments from an aquaculture and a non-aquaculture site. We now show that levels of antimicrobial resistance genes (ARG) are significantly higher in antimicrobial-selected marine bacteria than in unselected bacteria from these sites. While ARG i...

Abstract The emergence of colistin resistance is one the most serious future issues since it a last‐resort antibiotic used to treat infections caused by multidrug‐resistant (MDR) gram‐negative bacteria, particularly those resistant carbapenems. aquatic environment acts as reservoir for and spread pathogens. transmission plasmid mediated mcr gene important mechanism in gram negative bacteria. Se...

Objective: Isolation and identification of antibiotics resistant bacteria in raw milk. Methods: Luria-Bertani plates containing ampicillin (32 μg/mL), clindamycin (4 μg/mL), or chloramphenicol (32 μg/mL) were used in isolating the antibiotics resistant bacteria from samples; 16S rRNA analysis method was used to identify the isolates; blood agar plates were used in hemolysis assay; K-B disk diff...

The quotation above has led to the commonly held view that all bacteria will eventually become resistant to any antibiotic given enough time and exposure. However not all bacteria develop resistance to antibiotics at the same rate (and perhaps some species of bacteria may never develop resistance to certain antibiotics). And some bacteria that have been labeled “resistant” are not, in any clini...
