Estudo retrospectivo e comparativo da prevalência de Giardia sp. em cães, gatos e pequenos ruminantes em áreas endêmicas em diferentes estados brasileiros / Retrospective and comparative study of Giardia sp. prevalence in dogs, cats, and small ruminants in endemic areas in different Brazilian states
During 2011 to 2017, 2,698 fecal samples of dogs, 359 fecal samples of cats and 320 fecalsamples of goats and sheep were analyzed. A total of 18.9% of the dogs, 24.8% of the cats, and 6.6% of the goats and sheep werepositive for Giardia sp. Only previous studies that used the zinc sulphate centrifugal flotation (Faust technique) were includedfor comparation of prevalence. The prevalence of Giardia sp. in samples of centrifugation-fluctuation in zinc sulfate was similarin dogs, higher in cats and lower for small ruminants when compared to previous investigations. 4.4% and 6.7% of the positivesamples from dogs and cats, respectively, were associated with some co-infection. Co-infections by Cystoisospora spp., Ancylostoma spp. and/ or Toxocara spp. were the most common for dogs and cats.
