The aims of the study were to evaluate a new PCR protocol designed to detect Aeromonas salmonicida in fish tissues and to develop a non-destructive method for the diagnosis of furunculosis. A set of primers (Fer3, Fer4), flanking a fragment of the fstA gene (coding for the ferric-siderophore receptor) was designed, showing to be sensitive and specific. When(More)
Sheep develop clinical diseases after 3-5 years after infection with Mycobacterium avium subsp. paratuberculosis (MAP). Clinical symptoms of paratuberculosis include persistent diarrhea and weight loss due to a chronic inflammation of the small intestine. Tissue alterations in the areas of the ileo-cecal junction are often observed. Here, we investigate the(More)
BACKGROUND The tissue growth necessary to achieve a complete or partial restitution ad integrum as a result of injury to soft tissue and/or hard times in reptiles is variable and often needs long time in relation to the species, to the habitat and to their intrinsic physiological characteristics. The purpose of this work was to see if the tissue(More)
The aim of this study was to investigate the carbohydrate composition of mucosubstances in the equine guttural pouches using conventional histochemical tests in conjunction with glycolytic digestion to degrade different classes of glycosoaminoglycans. In the goblet cells, the mucopolysaccharides contained chondroitin sulfate B, heparin, heparan sulfate and(More)
An adult discus (Symphisodon aequifasciatus) with a history of buphthalmia and anorexia was referred, from an aquarium, for clinical examination. Surgery was performed to enucleate the eye and obtain a definitive diagnosis. Macroscopic examination revealed a yellowish mass that affected the eye. Histologic examination of the mass revealed a poorly(More)
A case of an ovarian tumor is reported in an 8-yr-old South American sea lion (Otaria flavescens) kept in a marine park in Malta (35.57 degrees N, 14.25 degrees E). The neoplasm was a solid mass of dense sheets and nests of round to polyhedral, irregularly shaped cells with abundant, finely vacuolated cytoplasm. The nuclei were uniformly small and round to(More)
