“…), consistent with epidemiological studies of canids in China [46] and Iran [47]. Thirdly, one E. vogeli -positive sample was collected from the municipality of Sena Madureira, where clinical cases and seroreactivity to polycystic echinococcosis have been described in urban and rural areas [48, 49]. Fourthly, dogs fed infected raw viscera were found to be an important risk factor in the epidemiology of echinococcosis [8, 14, 50].…”

Background Echinococcus granulosus (sensu lato) (s.l.) and Echinococcus vogeli are causative agents of chronic zoonotic diseases such as cystic and polycystic echinococcosis, respectively. In Brazil, polycystic echinococcosis has a restricted geographical distribution in the North Region, while cystic echinococcosis is observed in the South Region. Domestic dogs (Canis familiaris) fed with raw viscera represent a risk factor for E. granulosus (s.l.) infection in the South Region. Although this practice is frequent, it remains unclear whether domestic dogs are infected with E. vogeli in the state of Acre, located in the Amazon basin in the North Region of Brazil. The aim of this study was to investigate this gap in the polycystic echinococcosis epidemiology.MethodsSixty-five fecal samples were collected from the ground in five municipalities (Sena Madureira, n = 14; Rio Branco, n = 06; Bujari, n = 06; Xapuri, n = 30; and Epitaciolândia, n = 09) located in the state of Acre, northern Brazil. The samples were screened for parasites by copro-PCR using the cox1 gene associated with automated sequencing.Results Echinococcus vogeli was molecularly confirmed in a sample from Sena Madureira and E. granulosus (sensu stricto) (s.s.) (G1) in a sample from Rio Branco.ConclusionsThese findings indicate that molecular assays are useful in typing Echinococcus taxa from fecal samples of dogs in northern Brazil. The present study is the first molecular record of E. vogeli in domestic dogs found in the state of Acre, reinforcing their role as a source of infection for humans. Because E. granulosus (s.s.) (G1) was detected for the first time in the North Region, from the epidemiological standpoint this finding is highly relevant, because it expands the known geographical distribution, which was previously restricted to the South Region of Brazil.

“…Doenças parasitárias de cunho zoonótico são endêmicas em grande parte do mundo e possuem sua transmissão continuada em virtude de diversos fatores como condições climáticas favoráveis, falta de hábitos de higiene da população (Paiva et al, 2014), descarte incorreto de vísceras de animais e manejo inadequado com dejetos dos mesmos (Pastore et al, 2003). Os cães são portadores de diversos parasitos internos como, Toxocara spp., Ancylostoma spp., Trichuris vulpis (Anaya et al, 2015), Dipylidium caninum, Echinococcus granulosus e Toxascaris sp.…”

As parasitoses zoonóticas transmitidas por animais de companhia possuem um caráter de agressão nos próprios animais e em seres humanos em alguns casos e ainda tem pouca divulgação junto à comunidade. O objetivo deste trabalho foi estimar a prevalência de parasitos zoonóticos em quatro bairros do município de Pelotas-RS. Foram realizadas coletas de amostras de fezes de caninos em vias públicas referente aos bairros Bom Jesus, Simões Lopes, Navegantes e Barro Duro, processadas pela técnica de Willis-Mollay (1921). Os parasitos zoonóticos encontrados foram o Ancylostoma spp. no intervalo de prevalência de 50% a 76,39%, Toxocara spp. entre 7,38% a 53%, Trichuris vulpis entre 18,06% a 25,26% e outros dois em menores prevalências como Toxascaris (0,48%) e Cestódeos (1,22%). Estes dados demonstraram a importância e o cuidado que se deve ter com animais de estimação preferencialmente os domiciliados e animais comunitários, bem como a importância que estes possuem na disseminação e continuidade de doenças zoonóticas as quais a população está frequentemente exposta.

New Aspects of Neotropical Polycystic ( Echinococcus vogeli ) and Unicystic ( Echinococcus oligarthrus ) Echinococcosis

SUMMARY Of the four species of the genus Echinococcus (Cestoda) distinguished by biological and morphological characteristics, two species, E. vogeli and E. oligarthrus, occur widely in the Neotropics. Approximately 200 cases of polycystic echinococcosis (PE) have been recorded from 12 countries in South America. Following early proliferation of E. vogeli in the human host, typically in the liver, the metacestode usually spreads in the peritoneal and pleural cavities, and numerous organs may be invaded. The clinical characteristics of PE in 81 patients with sufficient information are reviewed. Type I disease consists of polycysts in the liver and abdominal cavity (37% of the patients had this characteristic); type II is similar to type I but also includes hepatic insufficiency (26%); type III consists of cysts in liver and chest (14%); type IV consists of cysts only in the mesenteries (16%); and type V consists of cysts calcified in liver and lung (4%). The percentage of patients with polycysts in the liver was 81%, and the percentage of patients with polycysts in the chest was 14%. PE is most ready diagnosed by geographic origin of the patient and by means of ultrasound or computerized tomography scanning showing cysts and calcifications. The highest mortality was for patients with type II disease, due to hepatic failure and its complications. There were five patients who died due to surgical accidents, whereas 35 cases had uncomplicated surgery. Twenty-three patients died of PE, making the total mortality 29% (23 of 78 cases). None of the 13 patients treated only with albendazole, the most efficacious treatment, was completely cured. PE represents a severe medical problem in South America. A reevaluation of the characteristics of the metacestode of E. oligarthrus indicated that it is unicystic. Only three human cases are known (two with infection in the orbit and one with infection in the heart). The metacestode of E. oligarthrus, in contrast with that of E. vogeli, consists of a spherical, fluid-filled vesicle that enlarges concentrically and is not known to undergo exogenous proliferation.
