چکیده انگلیسی
In recent years, Texas has seen a dramatic increase in the number of clinical cases of Corynebacterium pseudotuberculosis (pigeon fever) infection in horses. Equine pigeon fever cases at Texas Veterinary Medical Diagnostic Laboratories (TVMDL) were analyzed with the objectives of investigating the spatiotemporal distribution and seasonal and annual trends of pigeon fever infection in horses in Texas between 2005 and 2011 and identifying high-risk areas and create a risk map for pigeon fever in horses in Texas. The study population consisted of horses culture-positive for C. pseudotuberculosis between January 1, 2005, and December 31, 2011 at TVMDL. The Poisson model of scan statistics was fitted to identify disease clusters. Empirical Bayesian smoothing was performed with the crude incidence estimates, followed by the geostatistical method of kriging to delineate high-risk areas. Cases increased 10-fold between 2005 and 2011. The annual cumulative incidence ranged from 9.3 to 99.5 per 100,000 horses at risk. Two seasonal peaks in the number of cases were observed in June and in December. Scan statistics identified a primary cluster in central Texas in 2011 (P < .0001 and relative risk of 9.2). Isopleth risk mapping also delineated a high-risk area in central Texas. High-risk areas were also detected in the panhandle and northern Texas. The epidemiological investigation supported anecdotal reports that pigeon fever is re-emerging in the Texas horse population. This study provides a baseline for future investigations of pigeon fever in the Texas horse population and serves as a reference for the disease distribution for veterinarians and horse owners.
