Abstract
Examination of histological slides of the urinary bladder from rats used in an experimental surgery revealed the presence of sections of the nematode, Trichosomoides crassicauda within the transitional epithelium. The parasite was surrounded by area of epithelial degeneration and necrosis, and area of mild to moderate epithelial hyperplasia. Inflammatory reactions were not remarkable as only a mild inflammatory process and edema in the submucosa which included eosinophils, mast cells and lymphocytes were observed in some of the slides. There was presence of embryonated eggs in female worms. This article reports the presence of this nematode parasite in laboratory rats used for research and recommends strict management and sanitary measures in laboratory animal houses.
