| risk factors associated with sero-positivity to toxoplasma gondii in captive neotropical felids from brazil. | from september 1995 to february 2001, blood samples were collected from 865 neotropical felids belonging to 8 different species. these animals were housed in 86 institutions located in 78 cities of 20 brazilian states. our goal was to identify the risk factors associated with sero-positivity to toxoplasma gondii in captive neotropical felids from brazil. all serum samples were tested by the modified agglutination test (mat), using formalin-fixed whole tachyzoites and mercaptoethanol. for each an ... | 2007 | 17140683 |
| serologic survey of domestic felids in the petén region of guatemala. | blood samples were analyzed from 30 domestic cats (felis domesticus) from the petén region of guatemala to determine the seroprevalence of common pathogens that may pose a potential risk to native wild felids. eight of the cats had been vaccinated previously; however, owners were unable to fully describe the type of vaccine and date of administration. in addition, blood samples were obtained from two captive margays (leopardus wiedii). samples were tested for antibodies to feline immunodeficienc ... | 2005 | 17315469 |
| serological survey of toxoplasma gondii in captive neotropical felids from southern brazil. | toxoplasma gondii is the causative intracellular protozoan of toxoplasmosis in human being and animals. members of the felidae family are considered the single definitive host for the infection; both wild and domestic cats are able to excrete oocysts in the environment. wild cats maintained in captivity may serve as source of infection for other clinically susceptible animals in the same environment. the aim of this study was to determine the frequency of t. gondii igg antibodies in 57 neotropic ... | 2010 | 20472340 |
| seroprevalence of toxoplasma gondii in captive neotropical felids from brazil. | seroprevalence of toxoplasma gondii was determined in 865 captive neotropical felids from 20 states from brazil, sampled from september 1995 to april 1997. sera were tested by the modified agglutination test (mat) using formalin-fixed whole tachyzoites and mercaptoethanol. antibodies (mat> or =1:20) to t. gondii were found in 472 of 865 (54.6%) cats: in 45 of 99 (45.9%) jaguarundis (herpailurus yagouaroundi), in 97 of 168 (57.7%) ocelots (leopardus pardalis), in 68 of 131 (51.9%) oncillas (l. ti ... | 2001 | 11777601 |
| toxoplasma gondii in free-ranging wild small felids from brazil: molecular detection and genotypic characterization. | brazil harbors the largest number of wild neotropical felid species, with ten of the twelve species recorded in the american continent. although these animals are considered to be definitive hosts for toxoplasma gondii, there are few descriptions of the parasite in these species. here, we performed a molecular detection of t. gondii by amplification of the marker its-1 from tissue samples obtained from 90 free-ranging wild small neotropical felids from rio grande do sul - brazil. of the sampled ... | 2013 | 23932730 |
