Summary
This summary is machine-generated.

Equine viral arteritis (EVA) is present in Germany, detected in stallion semen and 3.8% of horse sera. Seroprevalence increased from 1.8% to 6.8% between 1987-1989, necessitating a new control program.

Area of Science:

  • Veterinary Virology
  • Equine Infectious Diseases
  • Epidemiology

Background:

  • Equine viral arteritis (EVA), caused by the equine arteritis virus (EAV), is a significant concern in horse populations.
  • EAV has been isolated from seminal plasma of stallions in Germany, indicating viral shedding.
  • Previous serological data suggested a low prevalence, but recent findings indicate a potential increase.

Purpose of the Study:

  • To report the isolation of EAV from stallions in Germany.
  • To determine the seroprevalence of EVA in the German horse population.
  • To highlight the increasing trend of EVA seropositivity and propose control measures.

Main Methods:

  • Virological isolation of EAV from seminal plasma of stallions.
  • Serological screening of 739 horse sera for EAV-specific antibodies.

  • Comparison of current seroprevalence data with historical data from 1987-1988.

    • Main Results:

    • EAV was isolated from the seminal plasma of two stallions.
    • EVA virus-specific antibodies were detected in 3.8% (28/739) of tested horse sera.
    • Seroprevalence increased significantly from 1.8% in 1987-1988 to 6.8% in 1989.

    Conclusions:

    • EVA infection is prevalent in the German horse population, often without acute clinical signs.
    • The observed increase in seroprevalence underscores the need for enhanced surveillance.
    • A voluntary prophylactic program utilizing virological and serological testing is recommended to curb further spread.
