Distribution of the stx1 and stx2 genes in Escherichia coli isolated from milk cattle according to season, age, and production scale in southwestern region of Goias, Brazil
(Arquivo Brasileiro Medicina Veterinaria Zootecnia, 2018-11-01)
This study determined the distribution of stx1 and stx2 genes in Escherichia coli isolated from dairy herds with regard to animal age, season, and farm production-scale, and analyzed the phylogenetic distribution of the ...
Análisis in silico de la capacidad de dos técnicas de PCR para la detección del gen stx.In silico analysis of the capability of two polimerase chain reaction techniques for stx gene detection
(Asociación Argentina de Microbiología, 2008-03)
Escherichia coli productor de toxina Shiga es un patógeno emergente cuyo principal factor de virulencia son las toxinas Shiga (Stx). Estas toxinas se clasifican en 6 tipos (1, 2, 2c, 2d, 2e y 2f) que agrupan a 22 variantes. ...
Comparable stx2a expression and phage production levels between Shiga toxin-producing Escherichia coli strains from human and bovine origin
(Wiley Blackwell Publishing, Inc, 2020-02)
Shiga toxin-producing Escherichia coli (STEC) can cause diarrhea and severe diseases in humans such as hemolytic uremic syndrome. Shiga toxins (Stx) are encoded in prophages which play an important role in STEC pathogenesis. ...
Carcaterização denotípica e genotípica de Escerichia coli produtora de toxina shiga (STEC) isoladas de bovinos de corte no Estado do Paraná
(Universidade Estadual Paulista (Unesp), 2008-01-29)
Escherichia coli produtoras de toxina Shiga (STEC) são reconhecidas como agentes causadores de infecções em humanos em todo o mundo. O principal reservatório é o bovino. Neste trabalho, cepas de STEC previamente isoladas ...
The effect of saxitoxin and non-saxitoxin extracts of Cylindrospermopsis raciborskii (Cyanobacteria) on cyanobacteria and green microalgae
(Springer, 2016-02-01)
The effect of saxitoxins (STX) on phytoplankton species is poorly understood. To date, no correlation between STX concentrations and phytoplankton physiology has been reported. We investigated the effect of STX (STX+, ...
