Thermoregulatory responses of the peruvian penguin, Spheniscus humboldti

Comparative Biochemistry and Physiology Part A: Physiology, 1971
Abstract 1. 1. Gullet temperature, a better measure of core conditions than cloacal temperature in the Peruvian penguin, usually averaged 39·0°C. 2. 2. Basal metabolic rate averaged 196 kcal/day for three penguins of mean weight 3·87 kg, and was thus within 1 per cent of the prediction for the resting phase of the diurnal cycle. 3.

Homeopathic Treatment of Pododermatitis in Magellanic Penguins (Spheniscus magellanicus)

Homeopathy, 2020
Abstract Background Problems with the feet are common in penguins, with a particular predisposition to pododermatitis. This condition usually occurs due to the changes in normal activity that result from being held captive, but its precise pathogenesis is still undetermined.

Disseminated Toxoplasmosis in Black-Footed Penguins (Spheniscus demersus)

Avian Diseases Digest, 2011
Three 1- to 3-mo-old black-footed penguins (Spheniscus Demersus) died within 24 hr of showing central nervous signs such as ataxia. The birds were housed in a baby penguin crèche. At necropsy, peritonitis, pneumonia, hepatomegaly, splenomegaly, and renomegaly were evident.

Vision of the Humboldt penguin (Spheniscus humboldti) in air and water

Proceedings of the Royal Society of London. Series B. Biological Sciences, 1987
Abstract Refractive states measured by retinoscopy and photorefraction indicate that the eyes of the Humboldt penguin, Spheniscus humboldti, are approximately emmetropic in air and water. Extensive myopia in air, as predicted by earlier authors and by a recent anatomical study, is non-existent.

Diversity of MHC class I alleles in Spheniscus humboldti

Immunogenetics, 2016
The major histocompatibility complex locus (MHC) is a gene region related to immune response and exhibits a remarkably great diversity. We deduced that polymorphisms in MHC genes would help to solve several issues on penguins, including classification, phylogenetic relationship, and conservation.

Systemic Aspergillosis in an Oiled Magallanic Penguin (Spheniscus magellanicus)

Journal of Veterinary Medicine Series B, 2001
This report describes a case of fatal aspergillosis caused by A. fumigatus during the recovery of an oiled Magallanic penguin. The possible role of aspergillosis as a possible complication responsible for the mortality of penguins surviving the first days of treatment for oil is emphasized.
