Molecular detection of Toxoplasma gondii and Neospora caninum in seabirds collected along the coast of Santa Catarina, Brazil.

Toxoplasma gondii and Neospora caninum are two closely related protozoans that infect a wide range of animals, including birds. However, the occurrence of N. caninum and T.

Applying different morphometric intestinal mucosa methods and the correlation with broilers performance under Eimeria challenge.

The intestinal wall has on its surface, protrusions called villi that are responsible for the absorption of nutrients. Commonly, these structures have their dimensions measured to related more area surface with better absorption. However, the measurement of these villi neglects the inflammation and the presence of immature cells that increase the surface area but affect negatively the absorption and compromise the animal performance.

Molecular characterization of Sarcocystis spp. in seabirds from southern Brazil.

Sarcocystis spp. are cyst forming apicomplexan parasites that infect many vertebrates including birds. Sarcocystis spp.

Detection of Neospora spp. and Sarcocystis neurona in amniotic fluid and placentas from mares.

The closely related apicomplexa protozoa, Toxoplasma gondii, Neospora spp., and Sarcocystis neurona, have all been associated with neurological and reproductive diseases in horses. However, there is limited data regarding the presence of these three parasites in equine placental tissues and amniotic fluid.

Basal and Infectious Enteritis in Broilers Under the I See Inside Methodology: A Chronological Evaluation.

Recently, the inflammation of the intestinal mucosa has been related to many diseases in humans and animals. The concept of Microscopic Enteritis (ME) used in human pathology through the Marsh classification system has no counter-part in veterinary medicine. In poultry science, the I See Inside (ISI) methodology, unlike the current linear measures of villi and crypts, generates possibilities to describe and understand the avian ME.

Applying I see inside histological methodology to evaluate gut health in broilers challenged with .

The present study evaluated the effects of coccidiosis on histological parameters and performance of broilers submitted to a mild challenge with sp. A total of 132 broilers were randomly divided into two groups with 6 replicates of 11 birds each: negative control (NC) - birds uninfected and challenge (CH) - birds infected by gavage at day-one with 10x the manufacturer recommended dose of Bio-Coccivet R live vaccine by Biovet, with strains of and . From 1 to 28 d of age, weekly the zootechnical performance was evaluated and samples of the liver, duodenum, jejunum and ileum were collected and submitted to histological analysis by the I See Inside methodology (ISI).

Multicentric lymphoma in a giant anteater (Myrmecophaga tridactyla).

Neoplastic disease is not well documented in giant anteaters. This report describes a disseminated lymphoma in an adult male giant anteater (Myrmecophaga tridactyla) from the City Zoo of Curitiba, State of Paraná, Brazil. No clinical signs were noticed before its death, except for a slight inappetence.
