Experimental candidiasis in Japanese quail: pathological changes.
|
| Abstract |
Candidiasis was experimentally produced in young Japanese quail by oral administration of Candida albicans cells. Lesions were confined to upper digestive tract with most characteristic changes occurring on the mucosa of crop. No lesions were observed in other tissues of the body. The initial changes in the crop were characterized by thickening and yellowish-white necrotic plaques on the mucosa. From 10th day onwards, there was marked thickening and corrugations of the crop mucosa giving it a typical 'turkish towel' appearance. Varying degree of mucosal swelling was also observed in the oesophagus and proventriculus. Two of the infected birds also revealed yellowish-white necrotic plaques on the tongue at 7th and 10th day post-infection. The prominent microscopic lesions in the crop and tongue consisted of hyperkeratosis and parakeratosis with congestion of the subepithelial tissues. Varying degree of parakeratosis and epithelial hyperplasia coupled with subepithelial oedema and hypertrophy of glands was observed in the oesophagus. The proventriculus and small intestine revealed congestion, oedema, mild to marked goblet cell hyperplasia and focal epithelial sloughing. Fungal elements could be demonstrated in the sections of tongue up to 10 days while in crop up to 14 days post-infection. Reisolation of the fungus was consistently achieved from the crop of infected birds throughout the duration of the experiment.
