Etiologic and epidemiologic analysis of bacterial infectious upper respiratory disease in Thoroughbred horses at the Seoul Race Park.

Ryu SH, Koo HC, Lee YW, Park YH, Lee CW - J. Vet. Sci. (2011)

Bottom Line: Infectious upper respiratory disease (IURD) of Thoroughbred racehorses has been a frequent problem (29.6% of incidence) at the Seoul Race Park (Korea).Risk factors for IURD include the season with a high transfer rate (summer and fall), the stabling period (≤ 3 months), and age (2 to 3 years old), suggesting that the movement and new environment may have depressed the immune system of the horses and decreased their ability to respond properly to pathogens.The bacterial strains (n = 98) isolated from IURD horses included Pseudomonas spp., Escherichia coli, Staphylococcus spp., Streptococcus equi subsp. equi and zooepidemicus.

ABSTRACT
Infectious upper respiratory disease (IURD) of Thoroughbred racehorses has been a frequent problem (29.6% of incidence) at the Seoul Race Park (Korea). Risk factors for IURD include the season with a high transfer rate (summer and fall), the stabling period (≤ 3 months), and age (2 to 3 years old), suggesting that the movement and new environment may have depressed the immune system of the horses and decreased their ability to respond properly to pathogens. The bacterial strains (n = 98) isolated from IURD horses included Pseudomonas spp., Escherichia coli, Staphylococcus spp., Streptococcus equi subsp. equi and zooepidemicus.

Comparison of seasonal population turnover rates (A) and seasonal incidence rates of infectious upper respiratory disease (IURD) (B) at the Seoul Race Park (2001~2005). (A-B) a-dLetters indicate statistical differences (p < 0.01). The main populations of newly stabled horses (A) as well as IURD patients (B) were 2 and 3 years old (yr).

Figure 1: Comparison of seasonal population turnover rates (A) and seasonal incidence rates of infectious upper respiratory disease (IURD) (B) at the Seoul Race Park (2001~2005). (A-B) a-dLetters indicate statistical differences (p < 0.01). The main populations of newly stabled horses (A) as well as IURD patients (B) were 2 and 3 years old (yr).

Mentions: A number of risk factors for IURD occurrence were identified in this study including the frequent stabling seasons, the stabling period, and age of the horses. There was frequent movement of horses in and out of the Park in the spring, summer, and fall and the least amount of movement in winter (Fig. 1A, p < 0.05). The IURD incidence rate (Fig. 1B) was significantly higher in the summer and fall (p < 0.05). The main populations of newly stabled horses and IURD patients were 2 to 3 years old. The incidence rate of IURD in the 2 and 3 years old group (Table 2) was significantly higher than in other age groups (p < 0.05). The IURD incidence rate in horses stabled for less than 3 months (Table 2) was significantly higher than that for horses stabled for other periods of time (p < 0.05).
