First genetic characterization of human cystic echinococcosis in Uruguay.

ABSTRACT: Cystic echinococcosis is endemic and hyperendemic in Uruguay. The objective of this study was to determine the species and genotype of Echinococcus granulosus sensu lato in symptomatic patients with cystic echinococcosis who underwent surgery, together with the location and stage of the cysts. The study included 13 patients aged between 6 and 57 years old. Samples of cysts from these cases were analyzed using DNA extraction, polymerase chain reaction amplification and sequencing. The results revealed the presence of E. granulosus sensu stricto in all cases, with 12 samples belonging to the G1 genotype and 1 to the G3 genotype, suggesting that disease persistence might be related to the dog-sheep cycle. However, other intermediate hosts, such as cattle, could also be involved.
