“…Numerous epidemiological studies have identified viruses as causes of disease, including respiratory tract disease, in horses (Powell et al 1974a,b;Rose et al 1974;Horner et al 1976;Thomson et al 1977;Mumford and Thomson 1978;Fu et al 1986;Matsumura et al 1986Matsumura et al , 1992Sugiura et al 1987Sugiura et al , 1988aCarman et al 1997;Dunowska et al 1999;Mumford et al 1998). However, there are several differences between the approach taken in these studies, and that of the current study and the study by Burrell et al (1996), which may account for the different findings.…”

Summary In order to investigate the role of infectious agents in the aetiology of lower respiratory tract disease in Thoroughbred racehorses, a matched case‐control study was conducted. Cases were identified by the presence of coughing, and were compared to a control population matched on time of sample collection and location within the same training establishment. Tracheal wash samples were collected from 100 cases and 148 controls. Case horses were more likely than controls to have endoscopic and cytological evidence of airway inflammation. There was no significant association between serological evidence of infection by commonly implicated respiratory viruses and coughing. Similarly, mycoplasma were rarely isolated and were not associated with disease. In contrast, there was a strong association between isolation of greater than a total of 103 colony‐forming units/ml of tracheal wash and coughing. Individual bacterial species associated with disease included Streptococcus zooepidemicus, Streptococcus pneumoniae, Streptococcus suis, Streptococcus sanguis, Pasteurella spp and Bordetella bronchiseptica. This study provides evidence of the role of bacterial infection in the aetiology of lower respiratory tract inflammation in racehorses. However, in 58% of cases, few or no bacteria were isolated. Hence, at the time of identification of disease, there was no evidence of viral, bacterial or mycoplasmal infection in the majority of coughing horses. The aetiology of the signs observed in these horses requires further investigation.

“…Equine herpesvirus 2 (EHV-2) is a slowly growing, cell-associated gamma-herpesvirus. This virus is widespread throughout the equine population and has been isolated from horses of different countries like United Kingdom [ 1 ], Japan [ 2 ], Australia [ 3 ], New Zealand [ 4 ], Switzerland [ 5 ], Germany [ 6 , 7 ], United States [ 8 , 9 ], Canada [ 10 ], Hungary [ 11 ] and more recently, from Poland [ 12 ]. Although its role as a pathogen is controversial, some authors have reported its association with upper respiratory tract disease, inappetance, lymphadenopathy, immunosuppression, keratoconjunctivitis, general malaise and poor performance [ 8 , 13 , 7 , 16 ].…”

Equine herpesvirus 2 (EHV-2) infection in thoroughbred horses in Argentina

Background: Equine herpesvirus 2 is a gamma-herpesvirus that infects horses worldwide. Although EHV-2 has been implicated in immunosuppression in foals, upper respiratory tract disease, conjunctivitis, general malaise and poor performance, its precise role as a pathogen remains uncertain. The purpose of the present study was to analyse the incidence of EHV-2 in an Argentinean horse population and correlate it with age and clinical status of the animals.
