Field study of the safety, immunogenicity, and efficacy of an inactivated equine rotavirus vaccine.
Results suggest that the equine rotavirus vaccine is safe and immunogenic and that reasonable efficacy under field conditions can be expected.
Molecular epidemiology and genetic characterization of equine arteritis virus isolates associated with the 2006-2007 multi-state disease occurrence in the USA.
Full-length genomic sequence analysis of 18 sequential isolates of EAV made from eight carrier stallions established that the virus evolved genetically during persistent infection, and the rate of genetic change varied between individual animals and the period of virus shedding.
Outbreak of equine influenza among horses in Hong Kong during 1992
Equine-2 influenza virus A (H3N8) infection occurred among vaccinated thoroughbred horses in Hong Kong during November and December 1992, and vaccination did not prevent 75 per cent of the population from becoming infected, and half the infected horses developed clinical signs.
Analysis of serotypes and electropherotypes of equine rotaviruses isolated in the United States
A serologic survey of 184 mares in Kentucky, which was done to determine the incidence of H-1 and H-2 infections, showed geometric mean serum neutralizing titers to theH-2 strain of equine rotavirus to be significantly higher than those to the H- 1 strain.
Isolation of the contagious equine metritis organism from colts and fillies in the United Kingdom and Ireland
The findings emphasise the need for a thorough examination of the genital tract of colts and fillies as recommended in the code of practice for the control of CEM when they begin their breeding career.

Equine infectious anaemia (EIA) is a persistent viral infection of equids that remains viraemic carriers for life and, with very rare exceptions, yield a positive serological test result.
Rapid diagnosis of equine influenza by the Directigen FLU-A enzyme immunoassay
The Directigen FLU-A enzyme immunoassay was tested for its ability to detect equine-2 influenza viruses in nasopharyngeal fluids from horses and ponies and appeared to be more sensitive than haemagglutination for the detection of low levels of virus in embryonated egg cultures.
