| seroprevalence of toxoplasma gondii in llamas (lama glama) in the northwest usa. | serum samples from 283 llamas (lama glama) from oregon, washington state and idaho were tested for antibodies to toxoplasma gondii using the modified agglutination test. antibodies were found in 95 (33.5%) llamas. percent seropositivity in serum dilutions of 1:25, 1:50, 1:500, and 1:5000 was 9.5%, 18.3%, 4.9%, and 0.7%, respectively. | 1992 | 1466137 |
| clinical and serologic evaluation of two llamas (lama glama) infected with toxoplasma gondii during gestation. | two pregnant llamas (lama glama) infected with toxoplasma gondii and their offspring were evaluated clinically and serologically. llama 1 was inoculated orally with 1,000 infective occysts of the p89 strain of t. gondii at 82 days of gestation (dog). llama 2 became naturally infected with t. gondii between 26 and 119 dog. both llamas remained clinically normal and delivered healthy offspring. sera collected from both llamas during pregnancy and from their offspring before and after colostral ing ... | 1999 | 10207383 |
| detection of specific antibodies to neospora caninum and toxoplasma gondii in naturally infected alpacas (lama pacos), llamas (lama glama) and vicunas (lama vicugna) from peru and germany. | sera of an experimentally neospora caninum infected llama and a non-infected control llama were used to establish an immunoblot, an elisa and an ifat to detect antibodies against n. caninum tachyzoites. subsequently, serum samples collected from a total of 871 south american camelids (sac: lama glama, lama pacos, lama vicugna) of two farms in peru and from 32 sac of a farm in central germany were examined for antibodies against n. caninum and toxoplasma gondii. based on the recognition of specif ... | 2005 | 15893073 |
| toxoplasma gondii infection in adult llamas (lama glama) and vicunas (vicugnavicugna) in the peruvian andean region. | the present study was designed to investigate toxoplasma gondii infection in adult llamas (lama glama) and vicunas (vicugna vicugna) in the peruvian andean region, for which to date no information has been available. serum samples from 43 llamas (l. glama) and 200 vicunas were tested by ifat detecting titres of 1:50 or higher in 55.8% (33.9-70.9%) and 5.5% (2.8-9.6%), respectively. ifat titres ranged from 1:50 to 1:6400. in order to avoid cross reactions with closely related coccidian parasites ... | 2005 | 15893075 |
| evaluation of neospora caninum and toxoplasma gondii infections in alpaca (vicugna pacos) and llama (lama glama) aborted foetuses from peru. | the aim of this study was to investigate the participation of neospora caninum and toxoplasma gondii in abortion cases of peruvian llamas and alpacas. fifteen aborted foetuses were recovered from two main rearing areas of camelids in peru (central or south andean region). foetal histopathology was used to detect the presence of protozoal-associated lesions in target organs. n. caninum and t. gondii infections were confirmed by immunohistochemistry (ihc) combined with pcr and by pcr alone, respec ... | 2007 | 17931783 |
| seroprevalence of neospora caninum, toxoplasma gondii and sarcocystis sp. in llamas (lama glama) from jujuy, argentina. | llamas (lama glama) are south american camelids described as intermediate hosts of neospora caninum, toxoplasma gondii and sarcocystis aucheniae. due to the potential role of these protozoan infections as a cause of economic losses, the aim of this study was to determine the seroprevalence for t. gondii, n. caninum and sarcocystis sp. in llamas from argentina. serum samples from 308 llamas (>2 years old) were collected between 2005 and 2007. a total of 55 farms located in six departments of juju ... | 2008 | 18495344 |
