Diagnóstico microbiológico e histopatológico de mortalidade em avestruzes (Stru...

Several young ostrich, including nestlings, with lassitude and inappetence followed by death or victim of sudden death were immediately brought to diagnosis at an Animal Health Laboratory. At necropsy, animals presented hemorrhage and altered content of the vitelline sac, and necrotic foci in the small intestine; one animal showed necrotic pleuropneumonia with psammomatosus bodies in the lung parenchyma. The cu...

Comparison of serum hormone levels of captive and free-living maned wolves Chry...

Serum hormone levels were compared between captive and free-living maned wolves and seasonal variations of sex hormones were studied. Blood samples were collected from 16 male and 26 female adult animals from Brazilian zoos, and from 30 male and 24 female free-living adults to determine serum progesterone and testosterone by radioimmunoassay. Serum testosterone concentrations varied (P < 0.05) across seasons fo...

Mercury toxicity in the Amazon: contrast sensitivity and color discrimination o...

We measured visual performance in achromatic and chromatic spatial tasks of mercury-exposed subjects and compared the results with norms obtained from healthy individuals of similar age. Data were obtained for a group of 28 mercury-exposed subjects, comprising 20 Amazonian gold miners, 2 inhabitants of Amazonian riverside communities, and 6 laboratory technicians, who asked for medical care. Statistical norms w...

Bovine demodicosis: a case report

Tissues samples collected at necropsy from a 9 year-old Holstein cow were fixed in buffered 10% formalin for histological examination. Macroscopic finding did not reveal typical nodular cutaneous lesions. Vulvar microscopic sections of cutaneous tegument showed mites (Demodex bovis), alone and grouped in hair follicles and sebaceous glands.

Density, proportion, and dendritic coverage of retinal ganglion cells of the co...

We performed a quantitative analysis of M and P cell mosaics of the common-marmoset retina. Ganglion cells were labeled retrogradely from optic nerve deposits of Biocytin. The labeling was visualized using horseradish peroxidase (HRP) histochemistry and 3-3'diaminobenzidine as chromogen. M and P cells were morphologically similar to those found in Old- and New-World primates. Measurements were performed on well...
