| a maternal screening program for congenital toxoplasmosis in quindio, colombia and application of mathematical models to estimate incidences using age-stratified data. | we studied 937 pregnant women from quindio, colombia for the presence of specific anti-toxoplasma gondii igg antibodies using the indirect immunofluorescence antibody technique (ifat-igg). specific anti-t. gondii igm antibodies detected using the immunosorbent agglutination assay (isaga-igm) were investigated in patients with high titers in the ifat-igg (dilutions > or = 1:1,024). we used mathematical models based on the age prevalence results of the ifat-igg to estimate the number of seroconver ... | 1997 | 9288813 |
| detection by pcr of pathogenic protozoa in raw and drinkable water samples in colombia. | we evaluated the presence of dna of giardia, toxoplasma, and cryptosporidium by pcr, and of giardia and cryptosporidium genera by immunofluorescence antibody test (ifat), in water samples, before, during, and after plant treatment for drinkable water. we applied this method in 38 samples of 10 l of water taken from each of the water treatment steps and in 8 samples taken at home (only for toxoplasma pcr) in quindio region in colombia. there were 8 positive samples for cryptosporidium parvum (21 ... | 2016 | 26779921 |
| [molecular and biological characterization of the cibmuq/hdc strain, a reference strain for colombian toxoplasma gondii]. | there are few reports about characterization strains of toxoplasma gondii that analyze the differences between isolates from europe or united states with those obtained in south america. the current study analyzes virulence data from the mouse model, the gene sag2 polymorphism by pcr-rflp and microsatellite analysis in a single colombian isolate. the strain was isolated from blood of a child with congenital toxoplasmosis, living in armenia, colombia. analysis of virulence in the mouse showed tha ... | 2004 | 15551880 |
