Freqüência de aglutininas anti-Leptospira interrogans em eqüídeos, em Minas Gerais, 2003 a 2004 Arq. Bras. Med. Vet. Zootec.
Chiareli,D.; Moreira,E.C.; Gutiérrez,H.O.D.; Rodrigues,R.O.; Marcelino,A.P.; Meneses,J.N.C.; Almeida,V.M.A..
The goal of this research was to find the frequency and spatial distribution of infection caused by Leptospira interrogans in equidae in Minas Gerais State from September 2003 to March 2004. Samples of blood serum (6,475) were analyzed by microscopic agglutination test. From the total, 381 samples were positive (5.9 %), with title equal or superior to 1:200 for one or more serovars of leptospira. The most frequent serovars were Hardjo (Norma), Pomona, Bratislava, and Batavie. The higher frequency of equidae reagents were recorded at the North and Northeast region of Minas Gerais, followed by Triângulo Mineiro and Alto Paranaíba, then Central, West, Metropolitan area of Belo Horizonte, and South/Southwest.

Prevalence and spatial analysis of antileptospiral agglutinins in dairy cattle - Microregion of Sete Lagoas, Minas Gerais, 2009/2010 Arq. Bras. Med. Vet. Zootec.
Nicolino,R.R.; Lopes,L.B.; Rodrigues,R.O.; Teixeira,J.F.B.; Haddad,J.P.A..
The aim of this study was to evaluate the seroprevalence of leptospirosis in the dairy herds from Minas Gerais, Brazil, during the years 2009 and 2010. A total of 2,915 serum samples were collected from the lactating cows of 151 properties in eleven municipalities located in the Sete Lagoas region. The Microscopic Agglutination Test was used to detect antileptospiral agglutinins. An individual animal prevalence of 20.7% (95% CI = 17.1% - 24.3%) and a herd prevalence of 80.8% (95% CI = 73.8% = 87.7%) were determined. The most prevalent serovars were hardjoprajitno at 19.4%; hardjoprajitnostrain Norma at 17.4%; and hardjo-bovis at 17.4%. These results show the significance of the hardjo serovar in bovine leptospirosis cases in Minas Gerais.
