Intestinal Smooth Muscle Hyperplasia in a Rhea (Rhea americana)
Avian Diseases, 1995Smooth muscle hyperplasia of the small intestine occurred in an 18-month-old rhea (Rhea americana). The mucosal thickening was 2-3 mm, and the enlarged muscle layers averaged 5 mm thick. The intestinal villi were lengthened, pleated, and expanded by smooth muscle hyperplasia within the lamina propria.

SUCCESSFUL TREATMENT OF SUSPECTED EXERTIONAL MYOPATHY IN A RHEA (RHEA AMERICANA)
Journal of Zoo and Wildlife Medicine, 2005A 7-yr-old, adult, female greater rhea (Rhea americana) from the National Zoological Park presented with a 24-hr history of severe left leg lameness that progressed to an inability to stand. Blood work revealed creatine phosphokinase (CPK) above 50,000 U/L and elevated lactate dehydrogenase. The bird's condition deteriorated over the next week.

Identification of the swine pathogen Serpulina hyodysenteriae in rheas (Rhea americana)
Veterinary Microbiology, 1996Recently intestinal spirochetes were isolated from rheas in Ohio and Iowa with a necrotizing typhlocolitis. These intestinal spirochetes, strains R1 and NIV-1, were characterized and compared with other intestinal spirochetes, including strains of S. hyodysenteriae. Both rhea spirochetes were indole positive, strongly beta-hemolytic, grew under a 1% O2:

The inner ear of the common rhea (Rhea americana L.).
Brain, behavior and evolution, 1989The morphology of the inner ear in rheas was examined by light and electron microscopy. The shape is typically bird-like with very long semicircular canals. The anterior and posterior cristae have small septa cruciata. The vestibular sensory epithelia contain two main types of hair cell innervation; bouton-innervated hair cells and calyceal hair cells ...

The given article deals with preliminary results of studying the helminthofauna of Rhea americana L. acclimatized in the Askaniya-Nova reservation. All four investigated nestlings at the age of 2???2.5 months proved to be infected with helminths. Three species of helminths are detected, two of which ???

Multiple Intussusceptions in a Juvenile Rhea (Rhea americana) with Proventricular Impaction
Avian Diseases, 1997Multiple intussusceptions of the small intestine were identified in a 4-mo-old rhea (Rhea americana) that died acutely after chronically poor growth. The chick was one of a group of 12 chicks that exhibited musculoskeletal deformities, poor growth, and subsequent death.

Parasitology Research, 2019
The ciliate species Balantioides coli can be cross-transmitted between humans and several animal species. Usually harmless, sometimes it can be pathogenic and cause the death of the host. In birds, B. coli has been confirmed in ostriches by genetic analysis, but the identification from South American greater rheas (Rhea americana) and lesser rheas ...

Ontogeny of feeding and drinking in the greater rhea (Rhea americana)
Behavioural Processes, 1978Feeding and drinking movements of the greater rhea chick are analyzed. Feeding consists of five movements in the following sequence: orientation, pecking thrust, head lift, forward head jerk and swallow. Drinking is less complex, consisting of a downward movement followed by an upward movement.
