Background: Giardia, an intestinal parasite of asexual reproduction, is an important etiologic agent of diarrhea in animals andhumans, transmitted by orofecal route. The disease caused by this agent, giardiasis, is endemic in the world and representingan important public health problem. The aim of the present study was do a retrospective study to determine the prevalence ofGiardia sp. in fecal samples from dogs, cats, sheep and goats (small ruminants) evaluated at FMVZ Unesp, Botucatu, SP. Inaddition, this study presents a review of the literature on the prevalence of this protozoan in dogs, cats and small ruminants indifferent states of Brazil, according to the environmental of these animals.Materials, Methods & Results: 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.Discussion: This study reveals the presence of Giardia sp. in different animal species...(AU)
