Morphometry of the heart of greater rhea (Rhea americana americana, Linnaeus, 1758)

Anatomia, Histologia, Embryologia, 2020
AbstractHeart diseases in birds are frequent and generate significant production disorders. Morphometry is a valuable tool to provide fundamental information about heart conditions. Few studies have addressed morphological aspects of the heart of ratite birds, such as the Greater rhea.

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.

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

THIAFENTANIL-DEXMEDETOMIDINE-TELAZOL ANESTHESIA IN GREATER RHEAS (RHEA AMERICANA)

Journal of Zoo and Wildlife Medicine, 2012
Ratite 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

Chronic fascioliasis in farmed and wild greater rheas (Rhea americana)

Veterinary Parasitology, 2007
From 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.

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.

Microbial contamination of artificially incubated Greater Rhea (Rhea americana) eggs

British Poultry Science, 2003
1. This paper is a report of biological agents that contaminate Greater Rhea (Rhea americana) eggs during artificial incubation. 2. The cleanliness of eggs when collected, and the period of storage prior to incubation, were investigated to assess their effects on microbial contamination and hatchability. 3.
