Abstract
|
|
|
|
Viral respiratory infections are common in horses, notably equine herpesvirus infection and equine influenza, which primarily initiate secondary bacterial respiratory infections such as strangles caused by Streptococcus equi equi. A decline in the production of stallions has been associated with these respiratory diseases leading to adverse financial implications. This study investigated the antibody responses against respiratory diseases in horses from Jeju Island a year after vaccination. A low level of equine herpesvirus type 1 (EHV-1) (11.36%) antibodies was detected from stallions, however a high level of EHV-4 (95.84%) antibodies was detected from horses without vaccination against this infection suggesting that EHV-4 is ubiquitous in this horse population. In case of equine influenza, ranch stallions showed low positive rate (12.06%) whereas stallions from Subtropical Livestock Research Institute displayed higher positive rate (81.32%). Antibody responses against equine influenza and strangles revealed positive rates of 26.32% and 55.12%, respectively. These findings may draw attention towards the importance of developing an improved disease prevention and/or immunization program that will effectively control respiratory diseases in horses.
