Echinococcus granulosus genotype G1 dominated in cattle and sheep during 2003-2006 in Buenos Aires province, an endemic area for cystic echinococcosis in Argentina
Cystic echinococcosis (hydatidosis) is a severe and widespread disease, caused by the larval stage of the tapeworm Echinococcus granulosus; it affects large numbers of humans and farm animals annually, causing serious health and economic problems. Molecular studies have identified large genetic vari...
