Objective: This work aimed to describe the trachea of the Magellanic Penguin (Spheniscus magellanicus) through descriptive and morphometric approaches. Methods: ten adult male Spheniscus magellanicus were used, which were collected, fixed, and kept immersed in an aqueous solution of 10% formaldehyde. Res...
Uric acid is the main form of excretion of nitrogenous components in birds. The assessment verification samples, control, check of uric acid concentrations is widely used to detect kidney disease. High concentrations (up to five times) of uric acid in plasma can lead to the p...
Abstract The fidelity of the genomes is defended by mechanism known as Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) systems. Three Type II CRISPR systems (CRISPR1- cas, CRISPR2 and CRISPR3-cas) have been identified in enterococci isolates from clinical and environmental samples. Th...

Abstract Even today, an effective diagnostic test for aspergillosis in penguins is unknown, being the gold standard post-mortem examinations. The fungal antigen galactomannan (GM) has been used as a biomarker of disease in humans and is detected by the Platelia Aspergillus EIA (BioRad)®, a commercial k...
Abstract Avian malaria is one of the most important diseases of captive penguins. We employed morphometric techniques to evaluate hepatic hemosiderosis in rehabilitating wild Magellanic penguins (Spheniscus magellanicus) that were negative (n = 9) or naturally infected by different subgenera of Plasmodi...

Los pingüinos de Magallanes son entre las aves marinas, la especie más afectada por la contaminación con petróleo en Chubut y Santa Cruz. Una de las consecuencias adversas de la exposición a hidrocarburos y otros contaminantes es el aumento de los niveles celulares de especies reactivas del oxígeno...
Este trabalho apresenta valores hematológicos e bioquímicos de pinguins-de-Magalhães (Spheniscus magellanicus) juvenis que arribaram no Espírito Santo e Rio de Janeiro, litoral sudeste do Brasil, e foram encaminhados a reabilitação. Os valores médios obtidos foram: eritrócitos 2.55±0.54 milhões...
Chronic oiling affects seabirds, with short (individual survival) and long-term (dynamics of population) effects. Magellanic penguin is the most affected species in Argentina. The aim was to evaluate the use of blood biochemical-molecular biomarkers (MT and TBARs) to assess health status of Magellanic pe...
During the austral winter the appearance of the Magellanic penguin (Spheniscus magellanicus) is common on the southern coast of Brazil. The oil pollution constitutes a major cause of death of these birds. The monitoring of the weight and blood variables is important to make decisions during the rehabilit...
Magellanic penguins (Spheniscus magellanicus) usually arrive in poor body conditions at Brazilian beaches during the winter. Hematology provides valuable information about clinical and immunity status of the animals. The aims of this study were to determine the hematologic, total plasma protein (TPP) and...
