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.

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:

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.

Pulmonary aspergillosis in the threatened lesser rhea (Rhea pennata)
Comparative Clinical Pathology, 2013Two captive lesser rheas (Rhea pennata), a 4-year old and an 11-month old, died in captivity at the Vesty Pakos Zoo in La Paz, Bolivia. Clinical signs were similar in both of the individuals and included lethargy, incoordination, progressive weakness, and loss of appetite.

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.

Gonadal morphogenesis and sexual differentiation in rhea (Rhea americana)
Reproductive BiologyThe rhea (Rhea americana) is a docile and highly adaptable ratite with notable zootechnical potential for the production of meat, eggs, feathers, and leather. Beyond its economic relevance, captive breeding plays an important role in conservation. However, information on its embryonic and gonadal development remains limited-knowledge that is essential ...
