title: Cloning of an Enterococcus faecalis endocarditis antigen: homology with adhesins from some oral streptococci.
abstract: Serum from a patient with Enterococcus faecalis endocarditis was used to identify the gene efaA cloned in Lambda ZapII in Escherichia coli. Nucleotide sequence analysis revealed a 924-bp open reading frame encoding a protein with a predicted molecular weight of 34,768. The amino acid sequence of EfaA shows 55 to 60% homology to a group of streptococcal proteins, FimA from Streptococcus parasanguis, SsaB from Streptococcus sanguis, ScaA from Streptococcus gordonii, and PsaA from Streptococcus pneumoniae. Members of this group have been shown to be adhesins, and we hypothesize that EfaA may function as an adhesin in endocarditis.
