“…Very few studies were conducted in other regions, likely reflecting the social disparities existing throughout the country. Two studies [ 27 , 28 ] were conducted in Pernambuco (a state in the Northeast region). The first study found a prevalence of 50.0% for Giardia cysts in samples from the Beberibe River which suffers anthropogenic and animal contamination as demonstrated by high levels of E .…”

“…The first study found a prevalence of 50.0% for Giardia cysts in samples from the Beberibe River which suffers anthropogenic and animal contamination as demonstrated by high levels of E . coli found in its water (from 50,000 to ≥ 160,000 NMP/100mL) [ 27 ]. The second study investigated bacterial and parasite contamination of rainwater stored in tanks and clay pots, in a semi-arid region of Northeast Brazil.…”

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.

“…The occurrence of C. parvum oocysts in water is also ubiquitous in surface water (An et al., 2011; Bautista et al., 2018; Chuah et al., 2016; Damiani et al., 2013; de Freitas et al., 2015; Imre et al., 2017; L.

Studies investigating the occurrence of C. parvum oocysts in environmental compartments established their presence in soil (Balderrama‐Carmona et al., 2014; Barwick et al., 2003; Boyer & Kuczynska, 2010; Hong et al., 2014; Zopp et al., 2016).…”

A series of laboratory experiments was performed to investigate the transport and retention of viable C. parvum oocysts in soil columns homogeneously packed with loamy sand soils (Lewiston and Greenson series) and sandy loam soils (Sparta and Gilford series), and under hydrologic conditions involving the presence of an anionic surfactant—Aerosol 22 in artificial rainfall. To characterize the effect of surfactant on the mobility of C. parvum oocysts in the soils used in this study, these results were compared with previous laboratory‐scale column experiments of a previous study using soils contaminated with oocysts, under conditions identical to those described here except for the absence of the surfactant in the percolating water. Quantitative polymerase chain reaction was used for the detection and quantification of C. parvum oocysts in soil leachates to assess their breakthrough and in soil matrices to characterize their spatial distribution. Alterations in the rate and extent of transport of C. parvum oocysts were discerned per the physicochemical parameters analyzed—soil types, soil chemistry, and surfactant—and resulted in either the enhancement or hinderance of C. parvum oocysts adsorption to surfaces, and their movement in soils. In the case of loamy sand soils, the transport of C. parvum oocysts through the soil matrices increased with the application of surfactant for Sparta series and remained at a similar level for Gilford series. Regarding sandy loam soils, the movement of C. parvum oocysts through the soil matrices increased for Greenson series and decreased for Lewiston series with the application of surfactant.

“…Sites F3, F4 and F5 are located in an area of dense urbanization and receive a signi cant load of domestic sewage, which results in a considerable increase in the level of pollution in this river (Veras et al, 2016;Veras et al, 2019), aggravated by the direct disposal of waste from small industries in its surroundings. Previous studies have detected the presence of intestinal parasites (mainly protozoa and helminths) (Freitas et al, 2015) and pharmaceutical products (diclofenac and paracetamol) (Veras et al, 2019) in water samples from the Beberibe River, indicating it is the direct destination of untreated domestic waste in the river. Although the Beberibe River is considered one of the most polluted rivers in the region, it supplies water to about 100,000 people (Freitas et al, 2015).…”

Tropical rivers are the main destinations for tailings from urban, industrial and agricultural activities. The present study aimed to investigate if early stages of zebra sh (Danio rerio) development is a viable biological model to assess the toxicity of surface waters of tropical rivers, and whether that toxicity could be correlated to standard water quality indexes. Embryos were exposed to samples from 55 sites from 10 hydrographic basins of rivers in Pernambuco State, northeastern Brazil. Lethality rates, sublethal toxicity based on the general morphology score (GMS) and frequencies of abnormalities were analyzed. Signi cant mortality was observed in samples of 7 basins. The GMS indicated signi cant delay in embryo-larval development in 50% of the samples. Highest toxicity was detected in basins within Recife metropolitan area, where 61% of the samples caused sublethal toxicity. Most frequent developmental abnormalities included non-in ation of the swim bladder, delayed hatching and blood stasis. Highest frequencies of blood stasis were detected in samples with highest NH 3 concentrations, corroborated by a positive correlation suggesting the existence of a causal relationship. A signi cant correlation was detected between water quality indexes and GMS with a greater toxic effect being observed in samples collected in areas of greater urban density and greater contamination by domestic sewage. This study demonstrates that the early stages of the zebra sh is a viable ecotoxicological model to assess the toxicity of surface waters and can contribute to a better understanding between the chemical composition and the adverse effects suffered by sh early life stages in tropical rivers.
