Amphibians are commonly kept in laboratory and zoological facilities and are becoming more frequent as pets. However, many amphibian species are declining in the wild owing to a variety of infectious and noninfectious diseases. This article reviews the current state of knowledge of mycobacteriosis in amphibian species, including pathogenesis, clinical signs, appropriate diagnostics, treatment options, and zoonotic potential and prevention. It is hoped this review will provide clinical veterinarians and scientists the tools they need to provide better care for amphibian species suffering mycobacteriosis, as well as serve to stimulate additional research into amphibians affected by mycobacterosis.

Dermatologic disease is a common problem in pet rodents. This article describes the case of a pet golden hamster (Mesocricetus auratus) with dermatologic and other clinical signs (polyuria, polydypsia) similar to those found in other mammalian species with hyperadrenocorticism. Among other diagnostic tests, the urine cortisol/creatinine ratio was measured and was found to be increased, which appeared to support the diagnosis. Treatment with ketoconazole was initiated, without apparent success.

Dystocia is a common problem in guinea pigs, usually associated with complete fusion of the public symphysis. In this article, a less common problem, ectopic pregnancy, is described.
