Abstract in English:
ABSTRACT.- Aguiar D.M, Gennari S.M., Cavalcante G.T., Labruna M.B., Vasconcellos S.A., Rodrigues A.A.R., Moraes Z.M. & Camargo L.M.A. 2006. Seroprevalence of Leptospira spp in cattle from Monte Negro municipality, western Amazon. Pesquisa Veterinária Brasileira 26(2):102-104. Department of Preventive Veterinary Medicine and Animal Health, Faculty of Veterinary Medicine and Animal Production, University of São Paulo, Av. Prof. Orlando Marques de Paiva 87, São Paulo, SP 05508-900, Brazil. E-mail: danmoura@aptaregional.sp.gov.br
The prevalence of anti-Leptospira spp antibodies was investigated in 2,109 female cattle from 86 herds of Monte Negro municipality, Rondônia, Brazil. Sera samples were evaluated by Microscopic Agglutination Test against 24 leptospira serovars. Titers =100 for at least one of 24 leptospira serovars were detected in 1,114 cows (52.8%) from 82 (95.3%) herds. The adjusted overall prevalence for Monte Negro municipality was 53.9% (49-58.7%; CI: 95%). The most prevalent serovars were Hardjo (14.5%), Wolffi (12.3%), Shermani (10.8%), Patoc (7.9%), and Hebdomadis (6.1%). Other serovars worldwidely reported like Bratislava, Pomona and Grippotyphosa were detected in low levels.

#12 - Evaluation of the indirect fluorescent antibody test and modified agglutination test for detection of antibodies against Toxoplasma gondii in experimentally infected pigs
Abstract in English:
Minho A.P., Navarro I.T., Freire R.L., Vidotto O., Gennari S.M., Marana E.M. & Garcia J.L. 2004. Evaluation of the indirect fluorescent antibody test and modified agglutination test for detection of antibodies against Toxoplasma gondii in experimentally infected pigs. Pesquisa Veterinária Brasileira 24(4):199-202. Depto Medicina Veterinária Preventiva, Universidade Estadual de Londrina, Cx. Postal 6001, Londrina, PR 86050-970, Brazil. E-mail: italmar@uel.br
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.
