Mm. Pereira et al., A clonal subpopulation of Leptospira interrogans sensu stricto is the major cause of leptospirosis outbreaks in Brazil, J CLIN MICR, 38(1), 2000, pp. 450-452
Leptospira is a highly diverse genus comprising many species and serogroups
in Brazil as well as all over the world. However, a study by arbitrarily p
rimed PCR of 44 leptospiral strains isolated from humans during three diffe
rent outbreaks in Brazilian urban centers reveals that 43 of 44 isolates ex
hibit very similar fingerprints, Analysis of these isolates indicates that
ther belong to a clonal subpopulation of Leptospira interrogans sensu stric
to.
