Three strains isolated from Apodemus spp. were similar to Bartonella specie
s on the basis of phenotypic characteristics. Futhermore, genotypic analysi
s based on sequence analysis of the 16S rRNA and gltA genes and on DNA-DNA
hybridization showed that the three isolates represented a distinct and new
species of Bartonella. The name Bartonella birtlesii is proposed for the n
ew species. The type strain of B. birtlesii sp, nov. is IBS 325(T) (= CIP 1
06294(T) = CCUG 44360(T)).
