| A two-month-old lamb showing signs of severe neurological disease characterized by muscular tremors, hypermetria, and motor incoordination was submitted to the Veterinary Pathology Laboratory - Universidade Federal do Rio Grande do Sul, Brazil. At necropsy, the major findings were a marked reduction of the size of the cerebellum and bilateral dilatation of the lateral ventricles. Microscopically, areas of cellular disorganization in the cerebellar cortex, reduction of the granular layer of cerebellum associated with decreased density of cells, and the presence of large cytoplasmic vacuoles in the molecular layer were observed. Neurons of the gray matter of the brain and macrophages of the mesenteric lymph nodes stained positively by the... |

| ABSTRACT: This study discusses the causes of bird deaths recorded in a small aviary dedicated to the breeding of a few exotic, wild bird species. Findings from 28 birds were examined over a period of five years. About 40% of the deaths occurred in the first two weeks after hatching in the two most numerous species in the flock and such losses were mainly a result of starvation caused by inadequate nutritional management. Additionally, 28% of the cases affected recently introduced birds. Despite frequent treatment with anthelmintics; a total of 21% of the deaths in the flock could be attributed to parasitic diseases, most of them in recently acquired birds. Only three of the deaths could be associated with advanced age, all of the further cases were also... |

| In a commercial herd of 1250 wild boars, 56 animals were affected by anorexia, diarrhea, and wasting. Enlargement of mesenteric lymph nodes, thickening of ileal wall, and a white-yellowish ileal content were observed in two of the four animals necropsied. Microscopically, ileal crypts showed epithelial hyperplasia, moderate decrease in goblet cell density, lymphohistiocytic infiltrate in the lamina propria, and moderate depletion with histiocytic infiltrate in Peyer's patches. Curved rod-shaped organisms within the apical cytoplasm of enterocytes were observed in both Warthin-Starry and Lawsonia intracellularis-immunostained sections. PCV2 antigen was observed in ileal Peyer's patches of 3 wild pigs. Trichuris suis nematodes were found in the cecum of the... |
