Mixed Infection of , , and Gram-Negative Bacteria as a Cause of Death in a Brown Caiman : A Case Report.

This paper describes a fatal case of nontuberculosis mycobacteriosis in a four-year-old brown caiman kept in captivity. Although the clinical signs were asymptomatic, severe gross lesions were observed, namely necrotic inflammation of the intestines and granulomatous hepatitis. Microbiological and histopathological examination performed on the tissues collected postmortem revealed a mixed infection of and , secondarily mimicked with , , , and .

Genetic Relationship of Isolates Found in Subcutaneous Abscesses in Leopard Geckos .

Introduction: The article describes the occurrence and phylogenetic relationship of isolates found in subcutaneous abscesses of leopard geckos. The aim of the study was to determine the cause of the abscesses and to characterise isolated strains.

Material And Methods: Samples of abscesses from five animals and internal organs (lungs, liver, and gut) of three of them were tested for according to the PN-EN ISO 6579:2002/A1:2007 standard.

Complex bacterial flora of imported pet tortoises deceased during quarantine: Another zoonotic threat?

Turtoises are a great puzzle when it comes to their bacterial flora, the composition and structure of which are still unknown in details. Its component which has been best described so far is Salmonella spp., presumably due to the threat of reptile-associated salmonellosis in humans.

Reptilian transferrins: evolution of disulphide bridges and conservation of iron-binding center.

Transferrins, found in invertebrates and vertebrates, form a physiologically important family of proteins playing a major role in iron acquisition and transport, defense against microbial pathogens, growth and differentiation. These proteins are bilobal in structure and each lobe is composed of two domains divided by a cleft harboring an iron atom. Vertebrate transferrins comprise of serotransferrins, lactoferrins and ovotransferrins.
