Identification of Potential Vaccine Strains of Escherichia coli Isolates From Diarrhoeic Calves
This study aimed to identify vaccine candidate Escherichia coli strains isolated from diarrheic calves. Faecal samples collected from 500 calves were analysed, and E. coli strains were isolated and characterized phenotypically and genotypically. Antibiotic resistance profiles, virulence‐associated genes and MLVA genotyping were used to select 20 ...

Factors released by LPS and Stx1-treated ASTs induce activation and migration of PMN through HUVECd.
PMN were stimulated with CM-Control, CM−LPS, CM−Stx1 or CM−LPS+Stx1. CD11b (A) or CD66b (B) expressions were evaluated by FACS at 40 or 90 min after stimulation, respectively. In (C), HUVECd seeded on the upper chamber of a transwell were stimulated with

Shiga toxin binding to glycolipids and glycans. [PDF]
Immunologically distinct forms of Shiga toxin (Stx1 and Stx2) display different potencies and disease outcomes, likely due to differences in host cell binding.

ABSTRACT Zoonotic bacterial pathogens are a major concern for food safety, yet information regarding their occurrence in game meat remains fragmented. This systematic review synthesizes available data on Salmonella spp., Shiga toxin‐producing Escherichia coli (STEC), Listeria spp., Yersinia spp., and Campylobacter spp.

Increased HUVECd toxicity induced by factors released by LPS and/or Stx1-treated ASTs.
HUVECd were stimulated for 72 h with CM-Control, CM-LPS, CM-Stx1 or CM-LPS+Stx1. Detached dead cells were washed away and the remaining cells were stained and counted by optical microscopy for toxicity evaluation.

Bovine bacterial abortion caused by Escherichia coli infection
Abstract A 3‐year‐old, 500 kg Holstein cow aborted at 7 months of gestation. On histological evaluation of the fetal lungs, abundant neutrophils infiltrated the alveolar spaces, bronchi and bronchioles with intralesional Gram‐negative bacteria, immunolabelled with Escherichia coli immunohistochemistry.

Antibodies against Stx2 and Stx1.
Representative immunoblot strips from HUS or healthy children plasma reactive to Stx2 (A) and Stx1 (B) are shown. A) Lane 1 shows a mouse-polyclonal plasma reactive against Stx2 A and B subunits; positive human plasma showed reactivity to either the A ...

Screening of ESBL‐, pAmpC‐ and carbapenemase‐producing Escherichia coli among Swedish wildlife demonstrated a low occurrence of antibiotic resistance in wild animals. Only two ESBL/pAmpC‐producers were detected in red foxes originating from highly populated areas.

HUVECd were stimulated with CM-Control, CM−LPS, CM−Stx1, CM−LPS+Stx1 or with 0.5 µg/ml de LPS (HUVECd+LPS) for 24 h. Then stimulus was removed and Stx1 was added for another 18 h.
