| diagnosis of cystic echinococcosis on sheep farms in the south of argentina: areas with a control program. | in 2000 guarnera et al. proposed using elisa in canine faeces collected from the ground to detect dogs infected with echinococcus granulosus, thus determining sheep farms with active transmission. the objective was to evaluate the prevalence of e. granulosus infection in sheep farms of the patagonia. sheep farms were randomly selected in the provinces of río negro, chubut, neuquén, santa cruz and tierra del fuego (areas with control programs) and la pampa (comparison area). from one to three sam ... | 2004 | 15725535 |
| molecular characterization of echinococcus isolates indicates goats as reservoir for echinococcus canadensis g6 genotype in neuquén, patagonia argentina. | human cystic echinococcosis is a highly endemic zoonotic disease in the province of neuquén, patagonia argentina, although a hydatid control programme has been carried out since 1970. human infection due to echinococcus canadensis (g6 genotype) is frequent in neuquén. however, the reservoir for this species remains undetermined in a region where camels are absent. we investigated the fertility, viability and molecular epidemiology of hydatid cysts obtained from local goats, pigs and sheep in ord ... | 2010 | 20667482 |
| usefulness and validation of a coproantigen test for dog echinococcosis screening in the consolidation phase of hydatid control in neuquén, argentina. | hydatidosis is endemic in neuquén, patagonia, argentina, even though sanitary authorities have been performing a control programme since 1970. at present, the programme is in consolidation phase, and dogs have being evaluated by arecoline purgation. the aims of this study were to evaluate diagnostic performance of a coproantigen (cag) elisa test developed "in house" and to assess cag detection in prepatent period. we examined 8 dogs experimentally infected with echinococcus granulosus and 403 ru ... | 2010 | 20546931 |
| heterogeneous distribution of human cystic echinococcosis after a long-term control program in neuquén, patagonia argentina. | the present study is the first comprehensive analysis of human cystic echinococcosis (ce) epidemiological data carried out in the province of neuquén, patagonia argentina, after 34 years of uninterrupted control program. a retrospective study of all the official records of confirmed human ce cases between 1995 and 2004 was carried out. a total of 1107 cases were reported. the overall mean annual incidence (mai) was 24.4 per 100,000 inhabitants for the total population and 9.7/100,000 in the 0-14 ... | 2007 | 17317277 |
| cystic echinococcosis in argentina: evolution of metacestode and clinical expression in various echinococcus granulosus strains. | echinococcus granulosus hydatid cysts were examined in 41 patients from neuquén and tucumán provinces in argentina. sequencing of the mitochondrial cytochrome c oxidase subunit 1 (co1) revealed in 19 patients common sheep strain (g1), in 6 patients tasmania sheep strain (g2), in 1 patient cattle strain (g5), and in 15 patients camel strain (g6). in argentina the only known is the domestic cycle that affects dogs and herbivorous, including ovine, swine, cattle and goats. these strains produced a ... | 2004 | 15350868 |
| immunodiagnosis of human hydatid disease: applications and contributions to a control program in argentina. | the sequential development of the hydatid immunodiagnostic activities of the control program of the province of neuquén, argentina is described. test results were used to obtain immunological confirmation of clinical cases and to detect asymptomatic cyst carriers amongst residents of rural endemic areas. the information was also valuable for improving the accuracy of prevalence estimates of human hydatidosis and the quality of surveillance data in different areas of the province, characterized b ... | 1983 | 6414320 |
