Pulmonary Aspergillosis in a Great Rhea (Rhea americana)

Avian Diseases, 2002
A 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.

Tuberculosis in Farmed Rheas (Rhea americana)

Avian Diseases, 1994
Avian 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

Hemoglobinuric Nephrosis in a Rhea (Rhea americana)

Avian Diseases, 1995
An 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.

Chlamydiosis in Commercial Rheas (Rhea americana)

Avian Diseases, 1994
Mild 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 ...

Genetic identification of the ciliates from greater rheas (Rhea americana) and lesser rheas (Rhea pennata) as Balantioides coli

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 Inner Ear of the Common Rhea (Rhea americanaL.)

Brain, Behavior and Evolution, 2008
The 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 ...

Acute aflatoxicosis outbreak in rheas (Rhea americana) in Brazil: Case report

Toxicon, 2022
Aflatoxins are mycotoxins capable of contaminating food, and can cause toxic effects, teratogenicity, mutagenicity, carcinogenicity, and immune system depression. The presence of fungi which produce this metabolite in ingredients that compose the animal feed increased the risk of the emergence of aflatoxicosis. The objective of this study was to report

Necrotizing Typhlocolitis Associated with a Spirochete in Rheas (Rhea americana)

Avian Diseases, 1992
Necrotizing 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.
