| seroprevalence of toxoplasma gondii infection in stray and household cats in tehran. | the prevalence of anti-toxoplasma gondii specific igg in stray and household cats in tehran was determined by indirect fluorescent antibody test (ifat) on serum samples from 100 cats (50 stray and 50 households). overall infection rate was 63%. the infection rate in stray cats (90%) was significantly higher (p<0.001) than that of household cats (36%). last serum positive dilutions varied from 1: 32 to 1: 512 titres in which the highest percentage (27%) was for 1:256 and the least (4.8%) was at 1 ... | 2006 | 16529863 |
| isolation and molecular characterization of toxoplasma gondii strains from different hosts in iran. | toxoplasma gondii is one of the most prevalent protozoan parasites in iran. this study was aimed to isolate t. gondii from a variety of hosts and to genetically analyze the parasite isolates. the prevalence of t. gondii in different animal hosts was assessed in two provinces of iran, tehran and mazandaran in the central and northern parts, respectively. the latex agglutination (la) test was carried out, and antibodies were found in 24 out of 105 sheep, 5 out of 35 goats, 23 out of 45 free-rangin ... | 2007 | 17333278 |
| sensorineural hearing loss due to toxoplasma gondii in children: a case-control study. | sensorineural hearing loss (snhl) can follow congenital toxoplasmosis. treatment in the first year of life is associated with diminished occurrence of this sequel. in various parts of iran, the prevalence of antibodies to toxoplasma gondii ranges from 24% to 57.7%. we evaluate the possible role of toxoplasma gondii infection on the occurrence of snhl in children. | 2008 | 18559038 |
| a serological study on toxoplasma gondii infection among people in south of tehran, iran. | although toxoplasma gondii infection generally shows subclinical courses in adults, it may have severe pathologic effects on the fetus. for a survey of toxoplasmosis in shahr-e-rey area, south of tehran, iran, we conducted a serological study on 1,187 general populations using indirect fluorescent antibody (ifa) test. in this cross sectional study, cases were selected randomly by a local primary health care (phc) system. blood samples were collected in microcapillary tubes and sera were examined ... | 2009 | 19290094 |
| toxoplasmosis-associated abortion and stillbirth in tehran, iran. | this study was aimed to evaluate the role of toxoplasmosis in etiology of abortion and stillbirth based on molecular and serological techniques. | 2016 | 25564725 |
| the prevalence of toxoplasmosis in imam reza hospital blood bank samples, tehran, iran. | the prevalence of toxoplasma gondii (t.g) infection in blood donors has been poorly studied. the aim of this study was to assess the prevalence of acute and chronic toxoplasmosis in blood products. | 2014 | 25219635 |
| igg avidity elisa test for diagnosis of acute toxoplasmosis in humans. | serum samples, 100 in the total number, were collected from different laboratories in tehran, iran and tested for anti-toxoplasma specific igg and igm antibodies using indirect immunofluorescent antibody test (ifat). using the igg (chronic) and igm (acute) positive samples, the igg avidity test was performed by elisa in duplicate rows of 96-well microtiter plates. one row was washed with 6 m urea and the other with pbs (ph 7.2), then the avidity index (ai) was calculated. sixteen out of 18 (88.9 ... | 2012 | 22711919 |
