Molecular typing of, and distribution of genetic markers among, Burkholderia cepacia complex isolates from Brazil.

ABSTRACT: PCR tests were used to assign genomovar status to 39 non-cystic fibrosis (non-CF) and 11 CF Burkholderia cepacia complex isolates from patients in hospitals in Recife, Brazil. Non-CF isolates were assigned to genomovar IIIA (71.8%), genomovar I (15.4%), B. vietnamiensis (7.7%), and B. multivorans (5.1%). CF isolates were assigned to genomovar IIIA (18.2%), B. vietnamiensis (18.2%), and genomovar I (9.1%). Six CF isolates sharing recA PCR-restriction fragment length polymorphism (RFLP) and randomly amplified polymorphic DNA (RAPD) patterns could not be assigned to a genomovar. 16S rDNA sequence obtained from these isolates indicated a closest relationship to B. anthina, but the recA sequence was equally divergent from several genomovars. PCR screening indicated the presence of cblA in only
