[human hydatidosis in rio grande do sul (brazil): an estimate of its significance for the public health of the country].by means of data collected through personal visits to hospitals and clinics in the 24 counties of rio grande do sul held to be endemic for echinococcus granulosus an assessment of the importance of this disease is attempted. (barring new developments, these data reflect the situation in the country as a whole). the surgical incidence for 1990 was found to be 5.5 cases per 100 thousand inhabitants, far less than the rates for the neighboring countries. as concerns prevalence, in the absence of ad ...19921342124
echinococcosis in southern brazil: efforts toward implementation of a control program in santana do livramento, rio grande do sul.this investigation aimed to design a strategy for echinococcosis control in santana do livramento county, an endemic area in state of rio grande do sul (brazil). fecal samples from 65 dogs were obtained from urban, suburban and rural areas. purging with arecoline bromhidrate (ab) was done to visualize echinococcus granulosus, and enzyme linked immunosorbent assay (elisa) was performed to detect parasite coproantigen. samples were obtained at the beginning and at the end of treatment with praziqu ...200415286819
echinococcus granulosus sensu stricto, echinococcus canadensis (g7), and echinococcus ortleppi in fertile hydatid cysts isolated from cattle in southern brazil.echinococcosis is a cosmopolitan zoonotic infection that affects humans and animals. the aim of this study was to identify and characterize the fertile hydatid cysts from bovine viscera in order to verify different species and/or genotypes present in southern brazil. firstly, cysts were collected from a slaughterhouse, which received animals from different regions of rio grande do sul state (rs), considered an important area of occurrence of cystic echinococcosis. in total, 2396 cysts were analy ...201627554941
infection of humans and animals with echinococcus granulosus (g1 and g3 strains) and e. ortleppi in southern brazil.the rio grande do sul state, in southern brazil, is one of the foci of human cystic echinococcosis (ce). the sheep strain (g1) of echinococcus granulosus and echinococcus ortleppi (also known as cattle strain g5) have been reported before to infect livestock. however, up to the present, no molecular data are available on isolates of the e. granulosus complex from humans and dogs. the present study analyzed hydatid cysts from 6 ce patients and adult worms from 12 dogs. sequencing of the mitochond ...201021273000
the action of albendazole on hydatid cysts in sheep experimentally infected with eggs of echinococcus granulosus.according to the brazilian agricultural ministry, the prevalence of cystic echinococcosis in the state of rio grande do sul, brazil has decreased between 1990 and 1998, possibly due to the common use of albendazole to control parasites in sheep. therefore, albendazole (abz) action was tested on hydatid cysts of sheep experimentally infected with eggs of echinococcus granulosus in uruguaiana county (rs) with the aim of evaluating the observed changes in the parasite's prevalence. the sheep were d ...200818199387
echinococcus canadensis (g7) and echinococcus granulosus sensu stricto (g1) in swine of southern brazil.the cystic echinococcosis (ce) is an important zoonotic disease caused by the parasite echinococcus spp. in brazil, this parasite is present in rio grande do sul (rs) state, border with argentina and uruguay, causing several damages to human and animal health. this study aimed to identify echinococcus spp. in hydatid cysts of swine and evaluate the similarity of the genotypes through the phylogenetic analysis. a total of 3,101,992 swine were slaughtered in the central/northern region of rs/brazi ...201424566128
echinococcus granulosus sensu lato and taenia hydatigena in pig in southern brazil.this study aimed to identify the parasitical etiologic agents of visceral cysts in pigs from the central/northern region of rio grande do sul state, brazil. fifty-eight cysts were found in livers during veterinary inspection of swine slaughtered from january 2008 to 2012. collected samples were submitted to macroscopic and molecular analyzes. polymerase chain reaction (pcr), dna sequencing and blast alignment of sequences was used to molecular characterization of the samples. by pcr 10.3% (6/58) ...201526154965
echinococcus ortleppi (g5) and echinococcus granulosus sensu stricto (g1) loads in cattle from southern brazil.echinococcus granulosus sensu stricto (g1) and echinococcus ortleppi (g5) are haplotypes of the parasite formerly known as echinococcus granulosus sensu lato, which in its larval stage causes cystic hydatid disease, endemic in southern brazil. epidemiological and molecular knowledge about the haplotypes occurring in a region is essential to control the spread of the disease. the aim of this work was to analyze the haplotype frequency and fertility of hydatid cysts in cattle from the state of rio ...201222571833
