Rhodococcus Equi Infection And Interferon-Gamma Regulation In Foals, Lingshuang Sun

Theses and Dissertations--Veterinary Science

Rhodococcus equi (R. equi) is one of the most serious causes of pneumonia in young foals. The clinical disease is of great concern to breeding farms worldwide due to the impact of mortality on economic losses. While adult horses are resistant to R. equi, foals exhibit a distinct age-associated susceptibility. The mechanism underlying this susceptibility in foals is not well understood. Interferon-gamma (IFNg) plays an important role in the clearance of R. equi, but its expression is impaired in neonatal foals. Moreover, the regulation of this age-related IFNg expression in foals remains unknown. In humans, IFNg …
