| prevalence of neospora caninum and toxoplasma gondii antibodies in sera from camels (camelus dromedarius) in riyadh province, saudi arabia. | from april to december 2010, blood samples were collected from 412 healthy camels in riyadh province, saudi arabia and used to evaluate serological screening for neospora caninum and toxoplasma gondii infection by an indirect fluorescent antibody test (ifat). of the 412 camels, antibodies to n. caninum were found in sixteen in titers of 1:20 and in seven in titers of 1:40 using whole n. caninum tachyzoites as ifat slide (vmrd inc., pullman, wa 99163, usa). antibodies to t. gondii were found in n ... | 2011 | 21980764 |
| antibodies against toxoplasma in commensal rodents trapped in riyadh region, saudi arabia. | toxoplasma gondii, that protozoal parasite which causes toxoplasmosis, pays no respect to boundaries of zoology and geography. it has been reported in a large number of birds and mammals including man from nearly all over the world. in saudi arabia, the incidence of human infection ranges between 21% and 49.3%. in this paper, the level of antibodies against toxoplasma in sera of different species of rodents was measured by the indirect haemagglutination tests (iha). the seropositivities ranged b ... | 1994 | 8077747 |
| serological survey of toxoplasmosis in riyadh, saudi arabia, using the indirect haemagglutination test. | randomly selected sera from 1169 patients with no history indicative of toxoplasmosis were examined by the indirect haemagglutination test (iht) for toxoplasma gondii antibodies. twenty-one percent were positive with titres of 1:64 or greater. no significant difference was demonstrated between the sexes. the antibody rate increased with age and the highest geometric mean of reciprocal titres was observed between the ages of 40 and 59 years. among 63 patients with a history of symptoms suggestive ... | 1982 | 7080184 |

| prevalence of antibodies to toxoplasma gondii in horses in riyadh province , saudi arabia. | abstract the aim of the present study was to determine the seroprevalence of toxoplasma gondii in horses for sporting purposes in the province of riyadh, saudi arabia. in total, 266 serum samples from clinically healthy horses were analyzed for anti-t. gondii antibodies using the sabin-feldman dye test. antibodies to t. gondii were found in 84 (31.6%) horses, with specific titers of 1:16 (78 with a prevalence of 29.3%), 1:64 (4 with a prevalence of 1.5%), and 1:256 (2 with a prevalence of 0.8%). ... | 2011 | 21506811 |
| determination of seropositivity for toxoplasma gondii in sheep, goats and camels slaughtered for food and human consumptions in riyadh municipal abattoirs, saudi arabia. | serum samples from 891 sheep, 555 goats and 182 camels slaughtered for food and human consumption from three main municipal abattoirs in riyadh city, saudi arabia were tested for antibodies to toxoplasma gondii by the an indirect fluorescent antibody test (ifat). antibodies to t. gondii were found in 36.4% (325/891) sheep and 35.3% (196/555) goats and 23.6% (43/182) camels, at a dilution of 1:32 or more for goats and sheep and 1:64 or more for camels. there was no significant difference in infec ... | 2013 | 24640857 |
| the pattern of infection of the nervous system in riyadh: a review of 121 cases. | analysis of 121 consecutive cases with infection of the nervous system showed that the majority were the granulomatous infections, tuberculosis and brucellosis (53 cases (44 per cent)). thirty-nine patients had tuberculosis and 14 had brucellosis. the clinical and microbiological pattern of infection differs from that frequently reported from western countries. tuberculosis lesions presented with features of intracranial space occupying lesions (14), spinal cord compression (13) and lumbosacral ... | 1988 | 3252303 |
| genotyping of toxoplasma gondii from rats (rattus rattus) in riyadh, saudi arabia. | toxoplasma 3 main clonal lineages are designated as type i, ii, and iii; however, atypical and mixed genotypes were also reported. this study was conducted for detection of toxoplasma gondii genotypes in rats (rattus rattus) in riyadh region, saudi arabia. pcr test on t. gondii b1 gene was conducted on elisa igm positive samples for confirmation of the infection. however, genetic analysis of the sag2 locus was performed to determine t. gondii genotypes using pcr-rflp technique. pcr test on t. go ... | 2014 | 25031465 |
