Tuberculosis in Farmed Rheas (Rhea americana)
Avian Diseases, 1994Avian tuberculosis was diagnosed in two mature rheas on different ratite farms over a 2-year period. Both birds had died after progressively losing body condition. Caseonecrotic granulomas were scattered throughout the liver and spleen in both birds. Similar granulomas were in the lung of one bird and bilaterally in the subcutis cranial to the shoulder

Chlamydiosis in Commercial Rheas (Rhea americana)
Avian Diseases, 1994Mild to marked splenomegaly was observed in three of four rheas that died acutely in three unrelated commercial ratite facilities in Southeastern Louisiana. Mortalities occurred within a 5-week period in birds ranging from 2 months to 3 years of age. Multifocal hepatic and splenic necrosis with mononuclear cell infiltrates, typical of chlamydiosis in ...

Hemoglobinuric Nephrosis in a Rhea (Rhea americana)
Avian Diseases, 1995An eighteen-month-old female rhea (Rhea americana) was presented dead for necropsy. The owner reported having observed blood in the droppings. Gross examination revealed a rhea in good body condition with a copious amount of frank blood in the cloaca. Large masses of matted fescue grass (Festuca spp.) distended the ventriculus and jejunum.

Pulmonary Aspergillosis in a Great Rhea (Rhea americana)
Avian Diseases, 2002A 5-mo-old great rhea (Rhea americana) gradually became emaciated over a 1-wk period and died. Necropsy revealed several small yellow nodules in the lungs. Microscopically, the nodules consisted of granulomas containing numerous thin, 4-microm-diameter, septate, branching fungal hyphae.

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 ...

The karyotypes were prepared from feather pulp of specimens obtained from the Como Zoo, St. Paul, Minnesota. Takagi et al. describe a slightly hetromorphic acrocentric pair (Z and W) which they assign to size six position.

Abstract Large flightless birds with long legs and three toes, the hallux being absent. They have no clavicle and the tibia is ,without a bony bridge. There are no tail feathers. The caecae of the alimentary canal are large and the syrinx has only one pair of syringeal muscles.

Chronic fascioliasis in farmed and wild greater rheas (Rhea americana)
Veterinary Parasitology, 2007From 50 farmed Rhea americana slaughtered for human consumption, adult forms and eggs of Fasciola hepatica were found in 4. The other three livers were free of flukes but did show lesions caused by larval fluke migration. Histological lesions were similar to those caused by flukes in cattle and sheep.

THIAFENTANIL-DEXMEDETOMIDINE-TELAZOL ANESTHESIA IN GREATER RHEAS (RHEA AMERICANA)
Journal of Zoo and Wildlife Medicine, 2012Ratite anesthetic events are often dangerous because these birds use their powerful legs and clawed feet as a defense, and physical restraint can result in self-trauma or injury to handlers. Although various combinations of opioids, alpha-2 adrenergic agonists, and dissociative agents have been employed in ratites, few effective chemical immobilization

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.
