Effects of nonsteroidal anti-inflammatorydrug on prevalence of helicobacter like organisms in gastric mucosa of thoroughbreds horses

ABSTRACT

The aim of this study was describe effects of NonsteroidalAnti-inflammatory drug on prevalence of Helicobacter LikeOrganisms in gastric mucosa of Thoroughbreds horses. Werestudied 54 Thoroughbred horses in the national race Track“La Rinconada” Caracas-Venezuela. All equine were treatedby seven days with phenylbutazone at an intravenous doseof 4.4 mg/kg. All horses presented Equine gastric ulcer syndromeacute superficial gastritis (25/54), chronic gastritis witherosion focal (16/54), chronic gastritis with erosion focal andulcers (14/54) in the gastric in both regions mucosa squamousregion and glandular regions (fundus). Helicobacter Like Organismsinfection in the stomach was confirmed by Warthin-Starry (38/54). Gastric mucosa revealed numerous spiralshapedbacteria morphologically resembling Helicobacter LikeOrganisms in squamous regions, margo plicatus (20/38) andnumerous spiral-shaped bacteria in fundic glands (18/54). Inconclusion, we detected high presence of Helicobacter LikeOrganisms in the gastric mucosa of Thoroughbred horse’streatment with phenylbutazone.
