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.

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.

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 ...

The Inner Ear of the Common Rhea (Rhea americanaL.)
Brain, Behavior and Evolution, 2008The 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 ...

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 ...

Necrotizing Typhlocolitis Associated with a Spirochete in Rheas (Rhea americana)
Avian Diseases, 1992Necrotizing typhlocolitis was diagnosed in 13 juvenile common rheas (Rhea americana) from three separate of geographically isolated Ohio flocks, with mortality ranging from 25% to 80%. At postmortem examination, a diphtheritic membrane covered ulcerated cecal mucosa.

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.

Development of spermatozoa in the rhea
The Anatomical Record, 1989AbstractWe have examined the ultrastructural changes that take place during spermiogenesis in the rhea. Spermatozoa are characterized by a curved head a midpiece. A thin rod extends from the anterior tip of the spermatozoon through the center of the nucleus. A 3‐μ‐long distal centriole occupies the entire midpiece.

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.
