Investigations were undertaken to determine the genotypes of the parasite Echinococcus granulosus that were present in livestock animals on the island of Sardinia. Liver, lung, and spleen samples were obtained from 770 sheep, 229 cattle, and 277 pigs slaughtered in Sardinia between January 2003 and April 2005, and the number and fertility of hydatid cysts were determined. Protoscoleces and/or germinal layer were collected from individual cysts, DNA was extracted from 91 samples, and polymerase chain reaction (PCR) and PCR-restriction fragment length polymorphism (RFLP) methods were used for identification of the strain genotype for each sample (G1, G5, G6/G7). Fragments of the mitochondrial ..
