| 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 |
| 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 |
| [toxoplasmosis in french guiana. atypical (neo-)tropical features of a cosmopolitan parasitosis]. | toxoplasmosis, a typical cosmopolitan parasitosis, is a major health problem in french guiana. three factors account for this situation, i.e., (1) severity of toxoplasmosis in patients with hiv infection that is particularly prevalent in the area, (2) high risk of congenital transmission as shown by the steadily increasing prevalence of seropositivity in function of age in most of the guianese population and (3) recent identification of severe primary toxoplasmosis infection in immunocompetent p ... | 2006 | 17201300 |
| atypical toxoplasma gondii strain from a free-living jaguar (panthera onca) in french guiana. | like domestic cats, wild felids are involved in the complete infective cycle of toxoplasma gondii because they can host in their gastrointestinal tract sexually mature parasites and shed infective oocysts in their feces. we report, to our knowledge, the first isolation and molecular characterization of a t. gondii strain from the heart tissue of a free-living jaguar (panthera onca) in french guiana. sequencing at six polymorphic markers indicated that the jaguar isolate had an atypical genotype, ... | 2008 | 18256411 |
| seroepidemiology of toxoplasma gondii in zoo animals in selected zoos in the midwestern united states. | toxoplasma gondii infections in zoo animals are of interest because many captive animals die of clinical toxoplasmosis and because of the potential risk of exposure of children and elderly to t. gondii oocysts excreted by cats in the zoos. seroprevalence of t. gondii antibodies in wild zoo felids, highly susceptible zoo species, and feral cats from 8 zoos of the midwestern united states was determined by using the modified agglutination test (mat). a titer of 1:25 was considered indicative of t. ... | 2008 | 18605803 |
| serosurvey of smooth brucella, leptospira spp. and toxoplasma gondii in free-ranging jaguars (panthera onca) and domestic animals from brazil. | this study investigated the exposure of jaguar populations and domestic animals to smooth brucella, leptospira spp. and toxoplasma gondii in the cerrado, pantanal and amazon biomes of brazil. between february 2000 and january 2010, serum samples from 31 jaguars (panthera onca), 1,245 cattle (bos taurus), 168 domestic dogs (canis lupus familiaris) and 29 domestic cats (felis catus) were collected and analysed by rose bengal test for smooth brucella, microscopic agglutination test for leptospira s ... | 2015 | 26605787 |
| exposure of free-living jaguars to toxoplasma gondii, neospora caninum and sarcocystis neurona in the brazilian pantanal. | toxoplasma gondii, neospora caninum and sarcocystis neurona are related apicomplexan parasites that cause reproductive and neurological disorders in a wide range of domestic and wild animals. in the present study, the immunofluorescence antibody test (ifat) was used to investigate the presence of antibodies against t. gondii, n. caninum and s. neurona in the sera of 11 free-living jaguars (panthera onca) in two protected areas in the pantanal region of mato grosso state, brazil. ten jaguars (90. ... | 2017 | 25517539 |
| a coprological survey of parasites of wild neotropical felidae. | in conjunction with an ecological study of jaguars in the cockscomb basin of belize, central america, fecal samples from jaguars (panthera onca), jaguarundis (felis yagouaroundi), ocelots (felix pardalis), and pumas (felix concolor) were examined for parasite products (eggs, larvae, and oocysts). of the 45 samples examined, 39 (86.7%) were positive for parasite products, 23 of 25 (92%) jaguar samples were positive, as were all of the puma (4/4) and ocelot (8/8) samples. four of 6 samples from un ... | 1986 | 3783346 |
| seroprevalence of toxoplasma gondii infection in captive mammals in three zoos in mexico city, mexico. | antibodies to toxoplasma gondii were determined in 167 mammals in three zoos in mexico city, mexico, using the modified agglutination test (mat). overall, antibodies to t. gondii were found in 89 (53.3%) of the 167 animals tested. antibodies were found in 35 of 43 wild felidae: 2 of 2 bobcats (lynx rufus); 4 of 4 cougars (puma concolor); 10 of 13 jaguars (panthera onca); 5 of 5 leopards (panthera pardus); 7 of 7 lions (panthera leo); 2 of 3 tigers (panthera tigris); 2 of 3 ocelots (leopardus par ... | 2013 | 24063119 |
