| 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 |
| 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 |
| pcr-dgge analysis for the identification of microbial populations from argentinean dry fermented sausages. | different pcr-dgge protocols were evaluated to monitor fermentation process and to investigate bacterial communities developed in two artisanal argentinean fermented sausages. bacterial universal primers frequently used in pcr-denaturing gradient gel electrophoresis (dgge) were evaluated. lactic acid bacteria (lab) and staphylococci species isolated from tucumán sausages were used to determine the experimental conditions for pcr amplification and dgge differentiation. total microbial dna extract ... | 2005 | 15893830 |
