title: Occurrence of the G3 Indian buffalo strain of Echinococcus granulosus in cattle.
abstract: During a survey carried out to define the occurrence of Echinococcus granulosus in cattle bred in the province of Rieti (Central Italy), molecular diagnostics (PCR amplification and sequencing of a partial region of the mitochondrial CO1 gene) showed that 6/10 positive bovines harboured hydatid cysts (No.=16) genetically identical (95.8-100%) to the Indian buffalo genotype G3. As far the location of the 16 cysts, 11 of them were found in the lungs of three animals, whereas 5 cysts were in the liver of three parasitized hosts. The occurrence of genotype G3 in 60% of parasitized bovines living in an area never studied before provides more definite evidence about the existence of the strain in this region, and proves that cattle have to be considered a non-accidental host.
