In cooperation with HistoryThe carcass of a 14-month-old 18.5-kg female capybara (Hydrochoerus hydrochaeris) with a history of hind limb lameness for several days prior to sudden death was presented for necropsy. The capybara was born and raised at a privately owned petting zoo that housed a small herd of capybaras along with several other exotic species, including Patagonian maras, emus, and alpacas. The owner reported feeding the capybaras a diet of pelleted horse feed, a commercial macropod food, dog food, corn on the cob, lettuce, timothy hay, Bermuda grass, and various fruits and vegetables. The owner also reported that this capybara was small for its age and that several other capybaras in the herd had not grown to full size. This capybara had been found dead approximately 24 hours prior to necropsy.

“…Capybaras have been shown to have a wide range of endoparasites, but they appear largely resistant to their effects and show only a few signs of ill health [86]. The capybaras, being the largest rodents on earth, have been given a lot of attention.…”

In this review, information was summarized on endoparasites found in six non-domesticated neotropical animals. These mammals have the potential to be domesticated. The animals included three rodents, agouti (Dasyprocta leporina), lappe (Agouti paca), and capybara (Hydrochoerus hydrochaeris); a marsupial, manicou (Didelphis marsupialis insularis); and an artiodactyl, the collared peccary (Tayassu tajacu/Peccari tajacu) and a ruminant (the red brocket deer, Mazama americana). While there are many descriptions of the parasites present, the majority of publications failed to note the effect of them on the animals. Most information is available on endoparasites of capybara, while the endoparasites of the red brocket deer were the least reported. The manicou was reported to have had the most number of endoparasites, 44 species of parasites were reported, while there were only 24 endoparasites reported in the lappe. The most common parasites found in these neotropical animals were Paraspidodera uncinata, Strongyloides spp., Eimeria spp., Moniezia benedeni, Trichuris spp., Physocephalus spp., and Giardia spp. A large majority of the studies concluded that these animals were reservoirs for parasites that could affect domesticated livestock. Endoparasites of zoonotic significance were Echinoccocus spp., Trichuris spp., Giardia spp., and Cryptosporidium spp.

“…The effects of blood parasites, such as the protozoon Trypanosoma evansi, are little known. T. evansi is transmitted mechanically by biting flies of the Tabanidae family and there are reports that it causes a disease called "derrengadera", which appears to paralyze the hindquarters of capybaras, but this is rarely seen in the wild (Cueto, 2012; pers. obs.).…”

Parasites play a crucial role in the ecology of animals. They also appear to be important in mechanisms underlying sexual selection processes. In this article we study the prevalence, effect and potential role in sexual selection of the protozoon Trypanosoma evansi in capybaras, Hydrochoerus hydrochaeris. We collected our samples from the annual capybara cull of a ranch in Venezuela, using the volume of the snout scent gland as an indicator of dominance; the residuals of body weight as indicators of condition; and the residuals of the spleen mass as indicators of immune function. Overall prevalence was 30.9 % (N= 97) with no difference between males and females, and no relation between infection with T. evansi and condition. However, we found that infected animals had larger spleens (residuals), indicating an immunological cost of the infection. Furthermore, males with larger snout scent glands (more dominant) were less likely to be infected than males with smaller glands (less dominant), suggesting that by choosing males with a large glands, females may be using the gland as an indicator of health, which is consistent with the "good genes" view of sexual selection. Rev. Biol. Trop. Parasites are important factors in the dynamics of their host's populations (Pedersen & Greives, 2008) by affecting their survival, reproduction (Albon et al., 2002) and behavior (Berdoy, Webster, & Macdonald, 2000). However, suspected parasites can often be commensals or even mutualistic symbionts (Ewald, 1987). Even when clear phenotypic effects of a parasitic infection are not apparent, an infection can carry a significant immunological cost (Lochmiller & Deerenberg, 2000). Parasites have also been hypothesized as central role players in the process of sexual selection. Thus, Hamilton and Zuk (1982) have argued -and presented evidence-that it is advantageous for a male bird to advertise his lack of parasites by developing and showing off bright coloration in his plumage. Such a display, being costly, would be an honest signal of condition which females could use to choose good quality males (Grafen, 1990;Keyser & Hill, 2000). In mammals, other features such as antlers or manes may play the same role as do colors in birds. In particular, the development of a scent gland and scent marking behavior may be subject to sexual selection (e.g. bats, Voigt et al., 2008; review by Penn & Potts, 1998) and may function as honest signals of health (Zala, Potts, & Penn, 2004).Capybaras, Hydrochoerus hydrochaeris (Linnaeus, 1758), large (50 kg), grazing rodents, are common in the savannahs and wetlands of tropical and subtropical South America (Ojasti, 1973), where they live in stable social groups composed of both males and females, with an average of 3-4 male and 6-7 female adults per group (Herrera & Macdonald, 1987;Herrera, Salas, Congdon, Corriale, & Tang-Martínez, 2011). In these groups, a clear-cut and long-lasting dominance hierarchy is evident among the males: the dominant male is usually able to win all encounters against m...
