Age-dependent prevalence of equid herpesvirus 5 infection.
Abstract: Equid herpesvirus 5 (EHV-5) infection was detected in a farm in Italy by the use of a semi-nested polymerase chain reaction (PCR) targeting glycoprotein B of EHV-5 on nasal swabs and blood samples of clinically healthy and randomly selected Lipizzaner horses (n = 55). Twenty-five horses at the age of 4-17 years and 30 at an age of 1-3 years were sampled once. The association of the infection with these age-groups and the gender of the horses was investigated. The apparent prevalence of EHV-5 infection was significantly different between age-cohorts: it was higher in the younger group of horses with 73,3% and 80% positives in nasal swabs and blood respectively, compared to 40% of nasal swabs and 20% of blood in the older horses. An age-dependence therefore was observed: the young age is more frequently associated with EHV-5 infection.

The research study investigates the prevalence of Equid herpesvirus 5 (EHV-5) infection in horses, specifically Lipizzaner horses in Italy, finding a higher rate of infection in younger horses compared to their older counterparts.
Objective and Methodology
- The researchers aimed to understand the prevalence and age-dependent factors relating to EHV-5 infection in Lipizzaner horses in Italy.
- To investigate this, the researchers conducted a semi-nested Polymerase Chain Reaction (PCR) test, targeting the glycoprotein B of EHV-5 in nasal swabs and blood samples from clinically healthy and randomly selected horses.
- A total of 55 horses were included in the study, with 25 horses aged between 4-17 years and 30 horses aged between 1-3 years sampled once.
Findings
- The study found a significant difference in the prevalence of EHV-5 infection between the two age cohorts: younger and older horses.
- In the younger group of horses (1-3 years old), 73.3% positive infection was observed in nasal swabs and a higher rate at 80% was seen in blood samples.
- On the other hand, in the older group of horses (4-17 years old), the infection prevalence was significantly lower with only 40% of nasal swabs and 20% of blood samples showing positive results.
Conclusion
- The research suggests there is an age-dependence factor associated with EHV-5 infection in horses, with younger horses more prone to the infection.
- This highlights the importance of age as a risk factor in considering prevention and treatment strategies for EHV-5 infections in horses.
- The study does not mention the association of infection with gender, suggesting that further investigation into this factor might be needed.
