Genetic and species rearrangements in microbial consortia impact biodegradation potential.

Genomic reorganisation between species and horizontal gene transfer have been considered the most important mechanism of biological adaptation under selective pressure. Still, the impact of mobile genes in microbial ecology is far from being completely understood. Here we present the collection and characterisation of microbial consortia enriched from environments contaminated with emerging pollutants, such as non-steroidal anti-inflammatory drugs.

Antimicrobial Residues in Poultry Litter: Assessing the Association of Antimicrobial Persistence with Resistant Strains.

: We set out to evaluate the persistence of sulfachloropyridazine, oxytetracycline, and enrofloxacin in broiler chicken litter following therapeutic oral treatment and its association with the isolation of resistant to these antimicrobials. : Forty broiler chickens were raised under controlled conditions and divided into three experimental groups, each treated with a different antimicrobial, in addition to an untreated/control group. Litter samples were collected post treatment, analyzed by UPLC-MS/MS, and processed for the isolation of .

Susceptibility to organophosphate insecticides in Aedes aegypti (Diptera: Culicidae) from northern Colombia and associated resistance mechanisms.

Background: Aedes aegypti is the primary vector of dengue, chikungunya, and Zika viruses in Colombia. Various insecticides, including pyrethroid, organophosphate, and carbamate insecticides; growth regulators; and biological insecticides, such as Bacillus thuringiensis var. israelensis, have been used to control Ae.

Impact of Surreptitious Glucocorticoids in Over-the-Counter Arthritis Supplements.

Adrenal dysfunction due to over-the-counter (OTC) health supplements containing unlabeled glucocorticoids has been previously reported. Here, we present a case series of 12 patients at an urban safety net medical center evaluated by endocrinology for iatrogenic adrenal dysfunction, Cushing syndrome (CS) and/or adrenal insufficiency (AI), associated with use of OTC arthritis supplements surreptitiously containing glucocorticoids. There were 12 patients using OTC arthritis supplements (Artri King [n = 8], Ardosons [n = 3], Ajo Rey [n = 1]) included.
