A 5-year-old Mangalarga mare was referred to the Veterinary Teaching Hospital of the Veterinary Medical School in Botucatu with a complaint of a persistent 2-month ovarian follicle which had grown progressively to 20 cm in diameter. Ultrasonography showed a circular, cystic structure in the right ovary, whose wall was thickened and interior was filled with anechoic content. Ovarian neoplasia was suspected, and a unilateral ovariectomy was performed through the paralumbar fossa, using general anesthesia through inhalation. Histopathological evaluation concluded that the ovarian enlargement was caused by a fibrothecoma. The present report describes features of fibrothecoma, which is extremely rare in the equine species. 相似文献

Dynamic computed tomography (CT) of the pituitary gland was performed in 55 dogs with pituitary-dependent hyperadrenocorticism (PDH) that underwent transsphenoidal hypophysectomy. On routine contrast-enhanced CT images, microadenomas of the pituitary gland often are indistinguishable from nontumorous pituitary tissue because of isoattenuation. Dynamic CT may allow visualization of these adenomas. The changes in the contrast-enhancement pattern of the pituitary during dynamic CT in 55 dogs with PDH were correlated with surgical and histopathologic findings. In 36 dogs, dynamic CT identified distinct contrast enhancement of the neurohypophysis (pituitary flush). In 24 dogs, this pituitary flush was displaced, which indicated the presence of an adenoma. This observation was confirmed surgically and histopathologically in 18 of the 24 dogs. In 19 dogs, there was a diffusely abnormal contrast-enhancement pattern. CT findings agreed with surgical findings in 13 of these dogs and with histopathologic findings in all 19 dogs. It is concluded that a dynamic series of scans should be included in the CT protocol of the pituitary gland in dogs with PDH because it allows for identification of an adenoma or a diffusely abnormal pituitary gland. 相似文献

Parasites of the genus Mammomonogamus affect the respiratory tract of domestic animals. The present study was carried out to determine the presence of Mammomonogamus laryngeus infection and to analyze its lesions in infected buffaloes in Rio Grande do Sul, Brazil, between April and November 1999. The infection rate was 30.5%. In 32 infected buffaloes, the worm pairs collected per animal did not exceed 20. The microscopic diagnosis showed intense polypoid to intramucosal proliferation at the entrance to the pharynx, to which the parasites had adhered, with foci of multifocal hydropic degeneration of the epithelium or individual degeneration of epithelial cells with mild intraepithelial inflammatory infiltrate. The submucosa revealed intense lymphocyte infiltrate extending into the salivary glands. The submucosa also showed formation of structures that resemble lymphoid follicles. 相似文献

桑天牛幼虫感染白僵菌后的组织病理学研究 总被引:2,自引:2,他引:0
桑天牛(Apriona germari)幼虫被球孢白僵菌(Beauveria bassiana)Bb00菌株感染后,虫体颜色及外部形态发生相应的变化。组织切片观察表明:白僵菌Bb00菌株处理后24 h,分生孢子即可以附着于桑天牛幼虫体表,48 h即可以萌发并侵入幼虫体表,使内表皮分解;菌丝进入血腔后开始增殖并向侵入点附近的脂肪、肌肉、气管等组织入侵。随着菌丝在幼虫体内的增殖,各组织器官遭到不同程度的破坏,4 d后感染幼虫死亡,5 d后菌丝突破体表在虫体外形成菌丝层并有分生孢子产生。 相似文献

300 goat serum samples from an export-oriented abattoir were tested for contagious caprine pleuropneumonia antibodies by the
complement fixation test. The disease prevalence was 31% with no significant differences (P > 0.05) between the regions “Borena”,
“Bale”, “Afar” and “Jinka” or the age of the goats (P > 0.05). Gross pathology and histopathology of the lung primary lesions
were indicative of pleuropneumonia caused by Mycoplasma capricolum subsp. capripneumoniae. 相似文献

Background: In the investigations of dogs with chronic small intestinal diarrhea collection of ileal biopsies lengthens procedural time and has been of uncertain value.
Objectives: To evaluate whether there was agreement between histologic changes present in samples of duodenal and ileal mucosa, and hence to provide initial information in the process of determining whether collection of ileal biopsies is clinically justified.
Animals: 40 dogs with chronic small and large intestinal diarrhea from which endoscopic (in 30 cases) or surgical (in 10 cases) duodenal and ileal biopsies had been collected.
Methods: Samples were reviewed concurrently by two observers (MJD and MDW) using the scoring system developed by the World Small Animal Veterinary Association (WSAVA) Gastrointestinal Standardization Group. Comparisons were made by kappa analysis.
Results: Microscopic pathology was observed in 30 cases. Only eight out of this 30 (27%) had the same histopathologic diagnosis in both the duodenum and the ileum. This dropped to 3 out of 30 (10%) if different disease severity was also considered as disagreement. Microscopic pathology would have been found in 60% and 80% of the 30 cases, if only duodenal or ileal biopsies respectively, had been available.
Conclusions and clinical importance: There was poor agreement between histopathological findings from duodenal versus ileal biopsies with abnormalities sometimes being more readily detected in the ileum. Routine collection of ileal plus duodenal samples appears warranted when concurrent small and large intestinal diarrhea is present. 相似文献
