FRISON DE COSTAS, Silvia et al. Diagnosis of cystic echinococcosis in faeces scattered in areas of Puna and Quebrada. Province of Jujuy, Argentina. Rev. argent. microbiol. [online]. 2014, vol.46, n.2, pp.80-84. ISSN 0325-7541.

Echinococcosis is a parasitic disease common in livestock, caused by the cestode Echinococcus granulosus, the dog being the principal definitive host. The province of Jujuy is an endemic area located in the Northwest of Argentina. Due to the restricted ecological conditions of Quebrada and Puna, the most important activity of the population is formal cattle pastoralism and transhumance, especially of sheep and camelids. The dog acquires the double function of company and shepherd in these communities. The objective of the present study was to conduct a diagnosis of the situation in areas of La Quebrada and Puna where the circulation of E. granulosus is suspected. Five hundred and twenty three (523) samples of canine fecal material scattered in the environment were collected from 2002 to 2012. Prevalence varied from 2% in Susques to 27.7% in Humahuaca, the largest in the province. In Tumbaya, prevalence was 21% in the year 2007, reaching 0% in the year 2010 but increasing again to 10.5% in the year 2011. These results may be related to health education on preventive measures and mass deworming held prior to sample taking in the year 2010. A prevalence between 19.4% and 2% was observed in the rest of the regions studied, suggesting that a lack of strategies for echinococcosis control has allowed the spread of the disease.
