Bartonella species can be differentiated by
microimmunofluorescence assay, sodium dodecyl sulfate polyacrylamide
gel electrophoresis (SDS-PAGE), and immunoblotting with murine
polyclonal antisera to Bartonella henselae, B. quintana, B. elizabethae, and B. bacilliformis. A pairwise comparison on the basis of SDS-PAGE
protein profiles demonstrated similarity values for proteins of
different Bartonella species ranging from 28.6 to 86.4%.
Antigenic relationships revealed by immunoblotting with murine antisera
were equivalent to those of proteins observed by SDS-PAGE. A dendrogram
obtained on the basis of protein bands of SDS-polyacrylamide gels
showed that Bartonella species could be divided into three
groups. B. bacilliformis was distinct from all other
Bartonella species; B. grahamii, B. taylorii, B. doshiae, and B. vinsonii
formed a cluster, as did B. henselae, B. quintana, B. elizabethae, and B. clarridgeiae. These relationships were consistent with those
revealed by parsimony trees derived from 16S rRNA and gltA
gene sequencing. SDS-PAGE analysis showed that 120-, 104-, 85-, 71-, 54-, 47-, 40-, 33-, 30-, and 19-kDa proteins were present in all
species, with the 54-kDa protein being the most dominant. Proteins with
a molecular mass of less than 54 kDa allow the differentiation of
species and are a possible target for future species-specific
antibodies and antigens.
