Complex adnexal masses are common and often present as a diagnostic dilemma. Many of these complex adnexal masses require timely recognition and treatment. Therefore, it is important to have a good differential diagnostic approach to these lesions. The classic differential for complex adnexal mass is the mnemonic "CHEETAH." This mnemonic may be a helpful memory device for residents, especially ...

Matrix population models are a common tool for evaluating different management strategies. In general, under deterministic analyses, management strategies are recommended that improve those matrix transitions that are most sensitive or elastic with respect to the asymptotic population growth rate, k. These recommendations usually ignore the biological limit for these transitions. In this paper ...

Many ecological theories and species conservation programmes rely on accurate estimates of population density. Accurate density estimation, especially for species facing rapid declines, requires the application of rigorous field and analytical methods. However, obtaining accurate density estimates of carnivores can be challenging as carnivores naturally exist at relatively low densities and are...

Muscle samples were taken from the gluteus, semitendinosus and longissimus muscles of a captive cheetah immediately after euthanasia. Fibres were 'skinned' to remove all membranes, leaving the contractile filament array intact and functional. Segments of skinned fibres from these cheetah muscles and from rabbit psoas muscle were activated at 20°C by a temperature-jump protocol. Step and ramp le...

This case report describes a multicentric lymphoma in a 4 yr old female wildborn captive cheetah (Acinonyx jubatus) in Namibia after being housed in an enclosure adjacent to a feline leukemia virus (FeLV) infected cheetah that had previously been in contact with domestic cats. The year prior to the onset of clinical signs, the wild-born cheetah was FeLV antigen negative. The cheetah subsequentl...

The cheetah ranks among the more vocal felids, and is above all a prominent purrer. However, the cheetah also produces a wide variety of other sounds, and this paper takes a closer look at a category of sounds produced by wild cheetahs, agonistic vocalizations, that can be divided into moaning, growling, hissing and spitting sounds.

The following case report describes a 1-year-old female cheetah (Acinonyx jubatus) with bilateral blindness and unresponsive pupils. For comparison, a second healthy 2.5-year-old male cheetah without visual deficits was also examined. Clinical examination of both animals included biomicroscopy, indirect ophthalmoscopy, tonometry, and electroretinography. The young female cheetah showed no menac...

INTRODUCTION Cryptococcus neoformans is a saprophytic yeast that is normally found in the environment associated with organic material such a pigeon droppings and leaf litter. However, C. neoformans is a potential pathogen of both humans and animals. The infectious particle, the basidiospore, is adapted for air dispersal and has properties that allow it to adhere to and penetrate the respirator...
