^aFour owned dogs were detected mixed infection of E. multilocularis and E. shiquicus
^bTen unleashed dog fecal samples were detected with mixed infection of E. multilocularis and E. shiquicus
^cOne unleashed dog fecal sample was detected with mixed infection of E. granulosus, E. multilocularis and E. shiquicus
Note: Data are presented as follows: prevalence (95% CI) in % (number of positive fecal samples/ total number of fecal samples examined)
