| genetic variation and epidemiology of echinococcus granulosus in argentina. | polymerase chain reaction-ribosomal its-1 dna (rdna) restriction fragment length polymorphism (pcr-rflp) analysis and sequencing of the mitochondrial cytochrome c oxidase subunit 1 (co1) and nadh dehydrogenase 1 (nd1) genes were used to characterize 33 echinococcus granulosus isolates collected from different regions and hosts in argentina, and to determine which genotypes occurred in humans with cystic hydatid disease. the results of the study demonstrated the presence of at least 4 distinct ge ... | 1999 | 10363285 |
| a case-control study of the risk factors for cystic echinococcosis among the children of rio negro province, argentina. | in 1984 the prevalence of cystic echinococcosis (ce) in rio negro province in central argentina reached alarming levels, with almost 6% of children aged 7-13 years infected with the causative agent, echinococcus granulosus. although the control activities developed between 1980-2000 have now lowered the prevalence of infection in this age-group to 1.1%, transmission of e. granulosus has clearly not ceased. the aim of the present study was to identify possible flaws in the control programme and t ... | 2002 | 11989533 |
| 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 |
