The study determined the sensitivity and specificity of the indirect fluorescent antibody test (IFAT) and modified agglutination test (MAT) for anti-Toxoplasma gondii antibody detection by analyzing sera from 46 experimentally infected pigs. Values for sensitivity were 95.7% (confidence interval 95%: 84.0-99.2%) and for specificity 97.8% (confidence interval 95%: 87.0-99.9%) in both tests. There was an optimum agreement of results between IFAT and MAT evidenced by a Kappa test of 0.86. These results validate these tests for the detection of T. gondii infection in pigs. IFAT and MAT despite methodologies with different characteristics and readings have similar accuracy in pig serum samples.

Results obtained in an enzyme-linked immunosorbent assay (ELISA), an indirect fluorescent antibody test (IFA), and a modified direct agglutination test (MAT) for Toxoplasma gondii antibodies from examination of fetal fluids from 377 aborted ovine fetuses were compared. Sixty-seven samples were positive by MAT (titers 1:16 to > 1:65,536), 58 were positive by ELISA, and 62 were positive by immunoglobulin G-IFA. The MAT was preferred because it required less time, labor, and special equipment. It was simple to run, could be done on serum from any species without modification, and it was more effective than the IFA for detecting toxoplasma antibodies in severely autolyzed fetuses. No advantage was found in determining immunoglobulin M antibodies in ovine fetal sera.

Antibodies to Neospora caninum were analyzed by an indirect fluorescent antibody test (IFAT), in stray and domiciled dogs from urban, periurban and rural areas from Curitiba, Paraná State, Brazil. Of the total of 556 dogs, 18.17% (101) were positive for N. caninum (titer 50). Frequency of antibody was 12.71 in urban, 15.73 in periurban, and 25.38% in rural dogs. Rural dogs had a significantly higher frequency of antibodies than urban dogs (P< 0.05). There were no significant differences between the frequencies of antibodies in urban and periurban dogs (P>0.05), and between dogs from periurban and rural areas (P>0.05). Antibodies to N. caninum were detected in 34 of 233 domiciled dogs (14.59%) and in 17 of 126 stray dogs (13.49%). No statistical differences were observed considering life-style and geographic location of origin (P>0.05). Neospora caninum is widespread among dogs from urban, periurban and rural areas of the municipal district of Curitiba, Paraná, Brazil.

Toxoplasma Gondii Infection

This report aimed to assess the seroprevalence of Toxoplasma gondii infection in 708 swine matrices in Nova Mutum and Diamantino in the state of Mato Grosso, Central-West Brazil. Serum samples were examined by indirect fluorescent antibody test (IFAT). It was found a seroprevalence of 12.8%, considering titers >64. Therefore, the data reinforce the need for appropriate management of swine raising to minimize the risk of infection of pigs with T. gondii.

AbstractToxoplasma gondii infections in free-range (FR) chickens (Gallus domesticus) are potential public health risks. Antibodies for T. gondii were found in 194 out of 303 serum samples (64.03%) from FR chickens in Thailand tested by the indirect fluorescent antibody test (IFAT, 1:16). To verify the validity of serologic data in this survey, sera from chickens experimentally infected with the RH strain of T. gondii were tested by the IFAT. Antibodies against T. gondii were detected as early as 7 days p.i., peaked at 2 weeks, and then declined by 10 weeks p.i.

Mycobacterium Smegmatis Atcc 607

Using the agglutination test and the indirect fluorescent antibody test it was demonstrated that lysogenization of the rough variant of Mycobacterium smegmatis ATCC 607 by mycobacteriophages D29 and B4 was accompanied by the appearance of new bacterial antigens. Each phage mediated a different bacterial antigen. That the new bacterial antigens were phage mediated was demonstrated by the loss of the new antigens when the bacterial culture was "cured" of the prophage.
