Evolution Of Equine Arteritis Virus During Persistent Infection In The Reproductive Tract Of The Stallion And The Male Donkey, Bora Nam
Theses and Dissertations--Veterinary Science
Equine arteritis virus (EAV) establishes persistent infection in the stallion reproductive tract, and the carrier stallion continues to shed virus in semen for weeks to years or lifelong. The objective of this study was to elucidate the intra-host evolution of EAV during persistent infection in stallions. Seven EAV seronegative stallions were experimentally infected with EAV KY84 strain and followed for 726 days post-infection, and sequential clinical samples including semen were collected for virus isolation and next-generation sequencing (NGS). In addition, archived sequential semen samples from two stallions that were naturally infected with EAV KY84 for a long-period (up to 10 …

Equine arteritis virus (EAV) is the causal agent of equine viral arteritis (EVA), a disease of equids. Following EAV infection, up to 70% of stallions may become carriers and continuously shed the virus in their semen for varying time periods. The long-term carrier stallion has an important role in the transmission and maintenance of EAV in horse populations. Recently, it has been demonstrated a correlation between in vitro susceptibility of CD3+ T lymphocytes to EAV infection and establishment of long-term persistent infection among stallions following natural infections. In this study, we investigated whether stallions with in vitro EAV susceptible …
