| 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 |
| 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 |
| presence and persistence of intestinal parasites in canine fecal material collected from the environment in the province of chubut, argentine patagonia. | we investigated the presence of intestinal parasites in canine feces collected from public squares in comodoro rivadavia, chubut, argentina (45 degrees s, 68 degrees w) and determined the persistence of echinococcus granulosus eggs in those droppings under natural environmental conditions in that region. in the first experiment, we analyzed 163 fecal samples collected from urban squares during 8 months time and found parasitic elements in 46.6%. the presence of parasites was independent of the c ... | 2003 | 14637028 |
