Identification of glycoproteins in mucous cells of the gill epithelium of Colossoma macropomum after exposure to organophosphate

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia
The use of organophosphates has been recommended for fish, especially the trichlorfon to control parasites. Colossoma macropomum were exposed to trichlorfon during 96 hours and of total number of mucous cells decreased in the number of cells when ...

Development of a quantum dot-labelled biomimetic fluorescence immunoassay for the simultaneous determination of three organophosphorus pesticide residues in agricultural products

open access: yesFood and Agricultural Immunology, 2019
In this study, we used 2-(diethexyphosphoryl)acetic acid as a common template molecule and Fe3O4@SiO2 as support material to prepare a superparamagnetic core/shell molecular imprinting polymer (MIP), Fe3O4@SiO2@MIP, which has multiple recognition sites ...

Challenges and opportunities in mitigating sarcoptic mange in wild South American camelids

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 1, January 2026.
Wild South American camelids—vicuña and guanaco—face threats from sarcoptic mange, a contagious skin disease linked to severe population declines. Despite its impact, major gaps remain in understanding disease dynamics. This review summarizes current knowledge, identifies key data and management gaps, and outlines urgent actions for effective ...

The dose-response relationship of trichlorfon neurotoxicity in hens

open access: yesEcotoxicology and Environmental Safety, 1979
Abstract Trichlorfon [dimethyl 1-hydroxy-2,2,2-trichloroethyl phosphonate (Dipterex)], an organophosphorus pesticide, has been implicated in producing neuropathy in various species. Adult hens were given oral or subcutaneous doses ranging from 50 to 300 mg/kg.
