Isolation and characterization of Leptospira interrogans from pigs slaughtered in São Paulo State, Brazil

Abstract: With the aim of isolating Leptospira spp., blood serum, kidney, liver and genital tract of 137 female swine (40 sows and 97 gilts) and also urine samples from 22 sows were collected in a slaughterhouse in the State of São Paulo, from April 2003 to August 2004. Four isolates were obtained from animals that presented microagglutination test (MAT) titers ≥ 100 for the serovar Pomona and one was obtained from an animal negative by MAT in which Leptospira was isolated from the liver and reproductive tract. The pres… Show more

“…Isolates GR5, GR6, KR9, KF10 and KR11 were first described by Miraglia et al [14]. The L. interrogans serogroup Pomona serovar Pomona reference strain 13A (1937, Australia) and L. interrogans serogroup Pomona serovar Kennewicki reference strain LPF (1985, Brazil) were used in this study as internal and quality controls.…”

“…O presente estudo obteve isolados de L. interrogans sorogrupo Pomona, e resultado semelhante ao encontrado, mas em suínos, foi descrito por Miraglia et al (2008), os quais realizaram a caracterização molecular dos isolados pela análise Multiple Locus Variable Number Tandem Repeat Analysis (MLVA), a qual também revelou padrão semelhante ao de L. interrogans sorogrupo Pomona sorovar Pomona estirpe GR6.…”

“…De fato, como o procedimento de tipificação das estirpes isoladas empregado só identificou a espécie das quatro estirpes e o sorogrupo de duas, não foram identificados os sorovares das mesmas, sendo necessário o emprego dos procedimentos clás-sicos para a identificação dos antígenos de superfície de natureza lipopolissacarídica, tais como a prova de absorção cruzada de aglutininas ou conjuntos de anticorpos monoclonais como já foi realizado em diversas localidades do Brasil, identificando em algumas ocasiões sorovares autóctones, só registrados até o presente unicamente no Brasil (SANTA ROSA; SULZER; CASTRO, 1972;VASCONCELLOS et al, 2001;DEL-BEM et al, 2002;MARVULO et al, 2002;CORRÊA et al, 2004;FREITAS et al, 2004;OLIVEIRA et al, 2005;AHMED et al, 2006;FAGUNDES et al, 2008;MIRAGLIA et al, 2008;ZACARIAS et al, 2008).…”
