Genetic diversity among capybara (Hydrochaeris hydrochaeris) isolates of Toxoplasma gondii from Brazil

Veterinary Parasitology, 2009
Recent studies indicate that Toxoplasma gondii isolates of many domestic hosts from Brazil are genetically and biologically different from T. gondii isolates from USA and Europe. However, little is known about genetics of T. gondii isolates from wild mammals in Brazil. In this study, genotypes of 36 T.

Experimental Leptospirosis in Capybaras (Hydrochaeris hydrochaeris) Infected with Leptospira interrogans Serovar Pomona

Journal of Zoo and Wildlife Medicine, 2009
Capybara (Hydrochaeris hydrochaeris), the largest rodent in the world, is widely distributed in South America. These animals live in areas with abundant water, which makes them a potential reservoir for Leptospira. The objective of this study was to investigate seroconversion, leptospiremia, and leptospiruria in capybaras experimentally infected with a

Isolation of Toxoplasma gondii from Capybaras (Hydrochaeris hydrochaeris) from São Paulo State, Brazil

Journal of Parasitology, 2008
The capybara (Hydrochaeris hydrochaeris) is a large rodent used for human consumption in certain areas of South America. In the present study, viable Toxoplasma gondii was isolated for the first time from this host. Antibodies to T. gondii were assayed in the sera of 64 capybaras from 6 counties of São Paulo State, Brazil, using the modified ...

Capybara (Hydrochaeris hydrochaeris rodentia: Hydrochaeridae): A mammalian seagrass herbivore

Estuaries, 2004
This note reports an unknown trophic interaction between a mammalian herbivore, the capybara (Hydrochaeris hydrochaeris), and the seagrassRuppia maritima (wigeongrass) and compares the feeding behavior of capybaras to other seagrass grazers. Observations were made in Spring 2002 in the Barra Grande, a small, shallow, moderately stratified, bar-built ...

A note on the cecotrophy behavior in capybara (Hydrochaeris hydrochaeris)

Applied Animal Behaviour Science, 2000
Abstract The capybara is a species that is bred for its meat in Brazil due to its elevated reproductive potential and because, being a herbivore, it does not compete directly with humans. Controversies exist regarding cecotrophy behavior in this animal.

Morphological Aspects of the Capybara Stomach (Hydrochaeris hydrochaeris): Gross and Microscopic Structure

Anatomia, Histologia, Embryologia, 2002
SummaryThe digestive system of the capybara has been investigated because of its coprofagia habits, important for their absorptive activity. These species present differences in terms of gastrointestinal morphological characters when compared with other rodents. Macroscopiclly, the stomach of the capybara is constituted of the following parts: cardiac,

Toxoplasma gondii in Capybara (Hydrochaeris hydrochaeris) antibodies and DNA detected by IFAT and PCR

Parasitology Research, 2010
Toxoplasmosis is considered nowadays as one of the most important foodborne diseases in the world. One of the emerging risks in acquiring infection with Toxoplasma gondii is the increasing popularity of wild animals and game meat. Capybara (Hydrochaeris hydrochaeris) is the world's largest extant rodent and is used for human consumption in many areas ...

Detection of Virulence Factors and Molecular Typing of Pathogenic Leptospira from Capybara (Hydrochaeris hydrochaeris)

Current Microbiology, 2012
Leptospirosis is a globally prevalent zoonosis caused by pathogenic Leptospira spp.; several serologic variants have reservoirs in synanthropic rodents. The capybara is the largest living rodent in the world, and it has a wide geographical distribution in Central and South America.
