Failure to remove bluetongue serotype 8 virus (BTV-8) from in vitro produced and in vivo derived bovine embryos and subsequent transmission of BTV-8 to recipient cows after embryo transfer [PDF]

open access: yes, 2019
The behavior of BTV-8 in cattle is different from most other serotypes not only with regards to clinical signs but certainly with respect to virus transmission (transplacental, contact). Therefore, the possibility of virus transmission by means of embryo

Multi-Year Persistence of Verotoxigenic Escherichia coli (VTEC) in a Closed Canadian Beef Herd: A Cohort Study

open access: yesFrontiers in Microbiology, 2018
In this study, fecal samples were collected from a closed beef herd in Alberta, Canada from 2012 to 2015. To limit serotype bias, which was observed in enrichment broth cultures, Verotoxigenic Escherichia coli (VTEC) were isolated directly from samples ...

Antigenic and biochemical characterization of bovine rotavirus V1005, a new member of rotavirus serotype 10 [PDF]

open access: yes, 1990
Bovine rotavirus (BRV) V1005 is serologically distinct from rotavirus serotypes 1, 2, 3, 4, 5, 6, 8 and 9. BRV V1005 showed cross-reactions with BRV B223, the American prototype of serotype 10 rotavirus, and with BRV E4049, a British serotype 10 isolate.

Detection of G12 Human Rotaviruses in Nepal

open access: yesEmerging Infectious Diseases, 2007
Of 731 stool specimens collected from children with diarrhea in Kathmandu, Nepal, from August 2004 through July 2005, 170 (23.3%) tested positive for rotavirus. Reverse transcription–PCR, including a revised G12-specific primer set, identified 56 (32.9%)

Serotypes of sex pili [PDF]

open access: yesEpidemiology and Infection, 1970
SUMMARYThere are situations in which direct observation of the attachment of antibody molecules may be the simplest method of detecting antigen-antibody reactions. Applied to the study of the sex pili determined by a number of transmissible bacterial plasmids, the method has distinguished four serotypes in the F-like class and two in the I-like class ...

Characterization of Shiga toxin-producing Escherichia coli O130:H11 and O178:H19 isolated from dairy cows

open access: yesFrontiers in Cellular and Infection Microbiology, 2013
Shiga toxin-producing E. coli (STEC) are isolated from human patients with bloody diarrhea, hemorrhagic colitis and hemolytic uremic syndrome. In the last years, the infections with non-O157 serotypes are increasing their frequency of association with ...

Genetic and antigenic characterisation of serotype A FMD viruses from East Africa to select new vaccine strains [PDF]

open access: yes, 2014
Vaccine strain selection for emerging foot-and-mouth disease virus (FMDV) outbreaks in enzootic countries can be addressed through antigenic and genetic characterisation of recently circulating viruses.
