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...

Em bovinos, as enfermidades parasitárias causam prejuízos econômicos e produtivos significativos. Além disso, comprometem a saúde e o bem-estar animal. Tratando-se mais especificamente dos endoparasitas, um fator agravante é a apresentação insidiosa da doença, e assim, são subdiagnosticados e/ou negligenciados. Por isso, a realização de estudos epidemiológicos de parasitas são ferramentas úteis para a identificação das espécies de helmintos, bem como para avaliar as suas prevalências e os graus de infecção nos animais. Com base nessas informações, medidas de profilaxia e prevenção podem ser mais bem delineadas. Apesar da relevância destes tipos de estudos, há escassez de resultados recentes e atualizados sobre a situação de rebanhos bovinos frente ao parasitismo. Desta maneira, objetivou-se realizar um levantamento retrospectivo de estudos epidemiológicos versando sobre endoparasitas nas diferentes regiões do Brasil, bem como de outros países de clima semelhante ao do Brasil, que foram categorizadas de acordo com seus climas tropical, subtropical e temperado.(AU)
In bovines, parasitic diseases cause significant economic and productivity damage. Furthermore, they compromise animal health and well-being. In the more specific case of endoparasites, one aggravating factor is the insidious presentation of the disease that renders it underdiagnosed and/or neglected. For this reason, epidemiological studies of parasites serve as useful tools for the identification of species of helminths, and for evaluating their prevalences and degrees of infection in animals. These data enable better delineation of preventive and prophylactic measures. Despite the relevance of these types of studies, recent updated results on the situation of bovine herds exposed to parasitism are scarce. Thus, the present work aimed to perform a retrospective survey of epidemiological studies examining endoparasites in different regions of Brazil, which also included international data, with countries categorized according to climates (tropical, subtropical and temperate).(AU)
