“…The presence of G . duodenalis is rarely analyzed in goats, but in two recent studies in Brazil, prevalence of the parasite ranged between 22.6% and 29.3% and the dominant genotype was genetic assemblage E [ 56 , 57 ]. A similar scenario is observed for studies with sheep.…”

Giardiasis as a neglected disease in Brazil: Systematic review of 20 years of publications

et al. 2017

IntroductionGiardiasis is an intestinal infection that affects more than two hundred million people annually worldwide; it is caused by the flagellated protozoan Giardia duodenalis. In tropical countries and in low or middle-income settings, like Brazil, its prevalence can be high. There is currently no systematic review on the presence of G. duodenalis in patients, animals or water sources in Brazil.MethodsThis systematic review was performed according to recommendations established by Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). As databases for our searches, we have used PubMed, Embase, Scopus and the Brazilian database SciELO using the keywords Giardia* and Brazil.ResultsThis systematic review identified research studies related to G. duodenalis in water, giardiasis in animals, prevalence of giardiasis across Brazilian regions, genotyping of strains isolated in humans, and giardiasis in indigenous populations. We also propose a network of G. duodenalis transmission in Brazil based on genotypes analyses.ConclusionThis is the first time within the last twenty years that a review is being published on the occurrence of G. duodenalis in Brazil, addressing relevant issues such as prevalence, molecular epidemiology and analytical methods for parasite detection.

“…Ruminants such as cattle and sheep are common hosts of uninucleate cyst-producing Entamoebae (Noble and Noble, 1952;Jacob et al, 1990;Hampton et al, 2006;Skirnisson and Hansson, 2006;Kanyari et al, 2009;Stensvold et al, 2010;Stensvold et al, 2011) and unidentified Entamoeba species have been reported in goats in Kenya (Kanyari et al, 2009), Thailand (Sangvaranond et al, 2010), Tanzania (Mhoma et al, 2011), Cameroon (Ntonifor et al, 2013) and Brazil (Radavelli et al, 2014).…”

This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. Until recently, the detection, identification and assignment of Entamoeba organisms to species relied mainly on morphology and the host in which parasites were identified (Stensvold et al., 2010;Stensvold et al., 2011). However, morphology is not a reliable tool for delimiting Entamoeba species as cyst morphology varies substantially within as well as between uninucleated cyst-producing species from different ruminant hosts (Noble and Noble, 1952;Pillai and Kain, 1999;Stensvold et al., 2010). The use of molecular tools is therefore essential to resolve the identification, taxonomy, epidemiology and clinical significance of Entamoeba species without reliance on parasite cultures or experimental infections (Stensvold et al., 2011; Jacob et al., 2016).Rangeland goats are an introduced animal species in Australia. They can be legally trapped and reared by licensed operators (goat depots) for the domestic and export meat markets, which was worth approximately $AUS242 million in 2014 (MLA, 2015). Few 4 studies have conducted genetic characterisation of Entamoeba species from ruminants (Stensvold et al., 2010; Jacob et al., 2016), which is important for understanding their evolutionary and taxonomic relationships. In the present study, uninucleate Entamoeba cysts were identified in the faeces of Rangeland goats in Western Australia by microscopy and were characterised at the 18S ribosomal RNA (rRNA) and actin loci. Materials and methodsFaecal samples were collected by rectal palpation from 125 male AustralianRangeland goats (Capra hircus) on arrival at a commercial goat depot near Geraldton, Western Australia, after capture and transport from a sheep and cattle extensive rangeland grazing property, North Wooramel station, located 78 km east of Denham and 113 km south east of Carnarvon in the Gascoyne region of Western Australia. On arrival, the goats weighed on average 30.7 ± 0.3 kg (±SEM), and the estimated age of the goats, based on dentition, was between 9 -12 months. Faecal samples were immediately placed on ice until transported to the lab, where microscopy work was performed on the same day of collection and then stored in the refrigerator (4.0°C) until DNA extraction was performed. All sample collection methods used were approved by the Murdoch University Animal Ethics Committee (approval number R2617/13).Direct microscopic examination of faecal suspensions in saline and wet mounted with 0.9% saline and Lugol's iodine was conducted. Entamoeba cysts were concentrated using zinc-sulfate gradient floatation (Faust's method) (Ramos et al., 2005) and observed ...

“…The lack of programs to control gastrointestinal parasites render animals more susceptible to infection by helminths and protozoa, worsening the condition of giardiasis in these animals, as observed by RADAVELLI et al (2014), in which 91.6% of the producers raised goats without parasitic control in the herd, and the owners reported constant mortality of goats due to diarrhea.…”
