Determination of the causes of infanticide in capybara (Hydrochaeris hydrochaeris) groups in captivity

Applied Animal Behaviour Science, 1999
Abstract The capybara ( Hydrochaeris hydrochaeris ) is a wild rodent of great economical interest, which are easily domesticated. Breeding these animals in captivity constitutes a great problem due to the high rate of offspring mortality caused by infanticide.

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 ...

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,

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 ...

Differential Distribution of Gonadotropin-Releasing Hormone Variants in the Brain of Hydrochaeris hydrochaeris (Mammalia, Rodentia)

Cellular and Molecular Neurobiology, 1999
1. In a previous paper we reported evidence for the presence of mGnRH- and sGnRH-like peptides in the preoptic-hypothalamic region of the capybara Hydrochaeris hydrochaeris (Montaner et al., 1998). In that study, the presence of a cGnRH-II like molecule in olfactory bulb extracts was suggested. 2.

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.

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.

Size of Testes and Scent Glands in Capybaras, Hydrochaeris hydrochaeris (Rodentia: Caviomorpha)

Journal of Mammalogy, 1992
The volume of the morrillo (snout scent-gland) of adult capybara ( Hydrochaeris hydrochaeris ) males was found to correlate significantly with testes mass ( r = 0.359, d.f. = 110, P < 0.0001). This was independent of body size. Males in better condition did not have larger testes or morrillos, whereas age did correlate with size of the morrillo and ...

BRUCELLA SPP. FROM THE CAPYBARA (HYDROCHAERIS HYDROCHAERIS) IN VENEZUELA: SEROLOGIC STUDIES AND METABOLIC CHARACTERIZATION OF ISOLATES

Journal of Wildlife Diseases, 1983
A bacteriological and serological study of 201 wild capybara from the llanos, State of Apure, Venezuela was made to isolate Brucella from spleen and lymph node tissues and determine the role of this rodent as a reservoir of this bacteria. Twenty-three isolations were made, eight were identified as B. abortus and 15 as B.

Gross anatomic organization of the capybara's (Hydrochaeris hydrochaeris) brachial plexus.

2003
The innervation of the capybara thoracic limb was characterized. The following nerves were observed constituting the right and left brachial plexus: n. dorsalis scapulae (C4 and C5; C4, C5 and C6) which innervates the m. serratus ventralis cervicis and m. rhomboideus; n. suprascapularis (C4, C5 and C6; C5, C6 and C7) supplying the m.
