capybaras in an anthropogenic habitat in southeastern brazil.capybaras (hydrochoerus hydrochaeris) are widely distributed in the neotropics, living in both natural and anthropogenic habitats. in the present study, we monitored the fluctuating capybara population at the campus "luiz de queiroz", university of são paulo, in piracicaba, southeastern brazil from 1998 to 2000. to assess population fluctuation and growth rates, we used an abundance index based on direct weekly daylight counts. population monitoring was carried out in an anthropogenic wetland as ...200616710529
natural infection with zoonotic subtype of cryptosporidium parvum in capybara (hydrochoerus hydrochaeris) from brazil.a total of 145 capybara (hydrochoerus hydrochaeris) fecal samples from the state of são paulo, brazil, were screened for cryptosporidium spp. oocysts using the malachite green method. eight samples (5.52%) showed positive results and were further submitted to nested pcr reaction for amplification of fragments of 18s rrna gene and 60-kda glycoprotein gene for determination of species, alleles and subtypes of cryptosporidium. sequencing of the pcr products of the 18s rrna gene fragments and 60-kda ...200717467175
rickettsial infection in capybaras (hydrochoerus hydrochaeris) from são paulo, brazil: serological evidence for infection by rickettsia bellii and rickettsia parkeri.in brazil, capybaras (hydrochoerus hydrochaeris) are important hosts for amblyomma ticks, which in turn can transmit rickettsiae to humans and animals. therefore, capybaras are potential sentinels for rickettsial infection.200718320102
prevalence of antibodies to trypanosoma cruzi, leishmania infantum, encephalitozoon cuniculi, sarcocystis neurona, and neospora caninum in capybara, hydrochoerus hydrochaeris, from são paulo state, brazil.little is known about the importance of capybara, hydrochoerus hydrochaeris, as reservoirs for parasites of zoonotic or veterinary importance. sera from 63 capybaras, from 6 counties in the state of são paulo, brazil, were examined for antibodies to trypanosoma cruzi, leishmania infantum, encephalitozoon cuniculi, sarcocystis neurona, and neospora caninum using an indirect immunofluorescent antibody test. five (8%) of the 63 capybaras had antibodies to t. cruzi epimastigotes. none of the samples ...201020020808
characterization of leptospira santarosai serogroup grippotyphosa serovar bananal isolated from capybara ( hydrochaeris hydrochaeris ) in brazil.leptospirosis is a widespread zoonosis caused by bacteria of the genus leptospira. rodents appear to be the most important reservoirs of infection. they contaminate the environment and food and can transmit the pathogen when they are consumed by carnivores. capybara ( hydrochaeris hydrochaeris ) are efficient reservoirs of leptospira, and because they are in close contact with farm animals and are found in semiurban areas, they represent a risk to public health. we isolated five leptospira strai ...201627258408
