Veterinary microbiology.Vet Microbiol.2015 Nov 18;180(3-4):260-7. doi: 10.1016/j.vetmic.2015.08.017. Epub 2015 Sep 15.
The purpose of this study was to characterize the virulence potential and determine the molecular epidemiology of extended-spectrum β-lactamases (ESBLs) in CTX-M-producing Escherichia coli isolated from piglets with diarrhea in China. A total of 62 E. coli isolates were obtained among which 49 and

Pathological and bacteriological characterization of neonatal porcine diarrhoea of uncertain aetiology.

Larsson J1, Aspán A2, Lindberg R3, Grandon R3, Båverud V2, Fall N1, Jacobson M1.
Journal of medical microbiology.J Med Microbiol.2015 Aug;64(8):916-26. doi: 10.1099/jmm.0.000108.
Neonatal porcine diarrhoea of uncertain aetiology has been reported from a number of countries. This study investigated 50 diarrhoeic and 19 healthy piglets from 10 affected Swedish herds. The piglets were blood-sampled for analysis of serum γ-globulin and necropsied, and the intestines were sample

Assessment of Adhesins as an Indicator of Pathovar-Associated Virulence Factors in Bovine Escherichia coli.

Valat C1, Forest K2, Auvray F3, Métayer V2, Méheut T3, Polizzi C2, Gay E4, Haenni M2, Oswald E5, Madec JY2.
Applied and environmental microbiology.Appl Environ Microbiol.2014 Dec;80(23):7230-4. doi: 10.1128/AEM.02365-14. Epub 2014 Sep 12.
The CS31A, F17, and F5 adhesins are usually targeted by serology-based methods to detect pathogenic Escherichia coli associated with calf enteritis. However, the virulence traits of the selected isolates are still poorly described. Here, from a set of 349 diarrheagenic E. coli isolates from cattle,

… that does not have any diarrheagenic characteristics other than the EAEC heat-stable toxin 1 (EAST1) gene is defined as EASTEC. … Although EAST1 has not been widely accepted as a virulence factor, we focused our attention on EASTEC because outbreaks due to EASTEC O166:H15 have occurred in several cities since the first incident in Osaka, Japan, in 1996. … EAST1, like the heat-stable enterotoxins of ETEC, may mimic guanylin and cause diarrhea. …
