Development of an ex vivo model to assess the impact of fumonisin B on swine intestinal morphology.

This study was conducted to assess the effects of fumonisin B (FB) on the jejunum of pigs using a novel ex vivo model conducted in parallel with an in vivo trial. For the in vivo model, twelve male 28 to 70-days-old pigs were subjected to two treatments of six animals each: the control group, fed a basal diet (BD), and the FB group, fed the BD + 50 mg/kg FB. At 70 days, the animals were slaughtered and one jejunal sample was collected from each pig for further histopathological analyses.

Pathological and etiological characterization of cases of bovine abortion due to sporadic bacterial and mycotic infections.

Opportunistic bacteria and fungi are commonly reported causes of bovine abortion in a small percentage of fetal losses of infectious etiology in cattle. The objective of this study was to characterize the pathological and etiological findings in fetuses aborted due to secondary bacterial and fungal infections submitted for postmortem examination between 2004 and 2019 in the State of Rio Grande do Sul, Brazil. Nineteen cases of bacterial etiology and five cases of fungal etiology were assessed.

Glial Fibrillary Acidic Protein and Ionized Calcium-Binding Adapter Molecule 1 Immunostaining Score for the Central Nervous System of Horses With Non-suppurative Encephalitis and Encephalopathies.

Like humans, horses are susceptible to neurotropic and neuroinvasive pathogens that are not always readily identified in histological sections. Instead, alterations in astrocytes and microglia cells can be used as pathological hallmarks of injured nervous tissue in a variety of infectious and degenerative diseases. On the other hand, equine glial cell alterations are poorly characterized in diseases.

Bovine Endometritis and the Inflammatory Peripheral Cholinergic System.

Endometritis is an inflammation of the endometrium associated with bacterial infection. The pathogenesis of endometritis in cows is still not completely understood. The combined analysis of the markers of inflammation and oxidative stress has contributed to a better understanding of disease mechanisms, but is still unexplored in uterine disorders.

Hydrallantois in cows naturally poisoned by in Brazil.

is a small subshrub that is distributed throughout Brazil and is responsible for lysosomal storage disease and occasional reproductive problems in cattle, goats, equids, sheep, and deer. We describe herein the clinical, epidemiologic, and pathologic features of hydrallantois in 3 cows naturally poisoned by in Rio Grande do Sul State, Brazil. Clinically, all cows had marked abdominal distension and mild ataxia.
