Bacterial communities in residential wastewater treatment plants are physiologically adapted to high concentrations of quaternary ammonium compounds
(2023-08-28)
Benzalkonium chloride (BAC) is a quaternary ammonium compound (QAC) widely used
as the active ingredient of disinfectants. Its excessive discharge into wastewater is
constant and in high concentrations, likely affecting ...
ClC-1 Chloride channel: Inputs on the structure–function relationship of myotonia congenita-causing mutations
(2023)
Myotonia congenita is a hereditary muscle disease mainly characterized by muscle hyperexcitability, which leads to a sustained burst of discharges that correlates with the magnitude and
duration of involuntary aftercontractions, ...
Emergence of Clostridium difficile NAP1 in Latin America
(2010-02)
The NAP1 and NAP2 strains of Clostridium difficile have been linked to nosocomial outbreaks of antibiotic-associated diarrhea (AAD) and pseudomembranous colitis in North American and European countries (4, 5). We found ...
A Novel Green Chemistry Method for Nonaqueous Extraction and High-Performance Liquid Chromatography Detection of First-, Second-, and Third-Generation Tetracyclines, 4-Epitetracycline, and Tylosin in Animal Feeds
(2012-06)
Although tetracyclines and macrolides are common additives for animal nutrition, methods for their simultaneous determination in animal feeds are nonexistent. By coupling an organic extraction and solid-phase extraction ...
Generation and implementation of reporter BHK-21 cells for live imaging of flavivirus infection
(2021-03-05)
The genus Flavivirus within the family Flaviviridae includes many viral species of medical
importance, such as yellow fever virus (YFV), Zika virus (ZIKV), and dengue virus (DENV), among
others. Presently, the identification ...
A geographical sampling method for surveys of mosquito larvae in an urban area using high-resolution satellite imagery
(2008-06-01)
Entomological surveys in urban areas are often biased by selecting houses or locations with known high vector densities. A sampling strategy was developed for Puntarenas, Costa Rica, using high-resolution satellite imagery. ...
Neotropical bats that co-habit with humans function as dead-end hosts for dengue virus
(2017-05-18)
Several studies have shown Dengue Virus (DENV) nucleic acids and/or antibodies present in Neotropical wildlife including bats, suggesting that some bat species may be susceptible to DENV infection. Here we aim to elucidate ...
