Horses fed meal contaminated with mycotoxins performing short-term exercises

Pesqui. vet. bras; 40 (9), 2020
This research was carried out to evaluate the effect of mycotoxins on the performance of horses through physiological parameters, and hematology and serum biochemistry analyses. The essay lasted 40 days, with 12 days for adaptation and 28 days of experimentation. In the experimental stage, the horses wer...

Incidência de aflatoxinas B1, B2, G1 e G2 em amendoins

Micotoxinas são substâncias tóxicas produzidas por fungos e encontradas nos alimentos. As micotoxinas mais tóxicas são as aflatoxinas, produzidas, principalmente por Aspergillus flavus. Estudos realizados no país demonstraram alta incidência dessas micotoxinas em produtos de amendoim, que r...

El factor de transcripción bZIP Afap1 afecta al estrés oxidativo y la biosíntesis de aflatoxinas en Aspergillus flavus
The bZIP transcription factor Afap1 mediates the oxidative stress response and aflatoxin biosynthesis in Aspergillus flavus

Rev. argent. microbiol; 51 (4), 2019
Abstract Aflatoxin is a carcinogenic secondary metabolite produced mainly by Aspergillus flavus and Aspergillus parasiticus, which can seriously endanger the health of humans and animals. Oxidative stress is a common defense response, and it is known that reactive oxygen species (ROS) can induce the synt...

Transcriptome and proteome analyses of resistant preharvest peanut seed coat in response to Aspergillus flavus infection

BACKGROUND: The infection of peanut (Arachis hypogaea L.) seed coat by the pathogenic fungus Aspergillus flavus has highly negative economic and health impacts. However, the molecular mechanism underlying such defense response remains poorly understood. This study aims to address this issue by profiling ...

The occurrence of aflatoxigenic Aspergillus spp. in dairy cattle feed in Southern Brazil

Braz. j. microbiol; 49 (4), 2018
ABSTRACT The presence of mycotoxins or related fungi in animal feed is a major problem for animal and human health. Silage and concentrated feed samples were collected from 21 dairy farms in the Western part of Paraná state in Southern Brazil. Water activity and pH of all samples were measured, and each...

Immunohistopathological and Biochemical Study of the Effects of Dead Nettle (Urtica Dioica) Extract on Preventing Liver Lesions Induced by Experimental Aflatoxicosis in Rats

West Indian med. j; 67 (3), 2018
ABSTRACT Objective: Aflatoxicosis is a mycotoxicosis infection with an acute or chronic course that forms due to aflatoxins (AFs) in humans and animals. Aflatoxins primarily affect the liver and can lead to histopathological necrosis, fibrosis and hepatocarcinogenesis of the organ. This paper studied th...

Surto de aflatoxicose aguda em cães no município de Pelotas/RS

Pesqui. vet. bras; 37 (11), 2017
As aflatoxinas pertencem ao grupo das micotoxinas e são substâncias sintetizadas durante a multiplicação de fungos que podem contaminar alimentos e rações animais, produzindo efeitos agudos ou crônicos naqueles que os consomem. Os cães são sensíveis aos efeitos tóxicos das aflatoxinas, havendo...
