Echinococcus granulosus antigen B gene family: further studies of strain polymorphism at the genomic and transcriptional levels.

Echinococcus granulosus AgB gene family is constituted by five gene loci. In a previous study, we analyzed the strain variation of EgAgB2/B4 sequences. Here, we have analyzed, by SSCP and sequencing, 250 genomic clones of EgAgB1/B3/B5 gene cluster from five E.
