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 Goiás, Brazil

Arquivo Brasileiro de Medicina Veterinária e Zootecnia
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 groups A, B1, B2, and D of 276 ...

Virulence Properties of Shiga Toxin-Producing Escherichia coli Isolated from Cases of Bovine Mastitis in Brazil

Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 2004
Out of 528 milk samples obtained from dairy cows with mastitis, 31 (5.8%) had Escherichia coli strains, causative agent of mastitis. These strains were screened for the presence of Shiga toxin-producing (stx1 and stx2) and intimin (eae) genes. Twenty (64.

Binding of Stx1 and Stx2 to purified glycolipids and mixtures.

, 2013
Stx binding was assessed by ELISA at 10 nM for both Stx1 (white columns) and Stx2 (black columns) at 4°C. The RFU signal is the mean of three independent experiments and error bars indicate SD. Since different antibodies were used to detect Stx1 and Stx2,

Selective Evolution of Ligands by Exponential Enrichment to Identify RNA Aptamers against Shiga Toxins

Journal of Nucleic Acids, 2014
Infection with Shiga toxin- (Stx-) producing E. coli causes life threatening hemolytic uremic syndrome (HUS), a leading cause of acute renal failure in children. Of the two antigenically distinct toxins, Stx1 and Stx2, Stx2 is more firmly linked with the

Interaction between Shiga Toxin and Monoclonal Antibodies: Binding Characteristics and in Vitro Neutralizing Abilities

Toxins, 2012
Monoclonal antibodies (MAbs) have been employed either for diagnosis or treatment of infections caused by different pathogens. Specifically for Shiga toxin-producing Escherichia coli (STEC), numerous immunoassays have been developed for STEC diagnosis ...
