| immunological response mounted by aboriginal australians living in the northern territory of australia against streptococcus pyogenes serum opacity factor. | streptococcus pyogenes (group a streptococcus) interacts with host fibronectin via a number of distinct surface components. the streptococcal serum opacity factor (sof) is a cell-surface protein of s. pyogenes which causes opalescence of human serum and mediates bacterial binding to fibronectin. in this study, hexahistidyl-tagged fusion proteins encompassing full-length sof, and domains of sof encompassing opacity factor activity and fibronectin-binding regions, were used in the characterization ... | 2002 | 11782509 |
| genetically distinct dog-derived and human-derived sarcoptes scabiei in scabies-endemic communities in northern australia. | overcrowding is a significant factor contributing to endemic infection with sarcoptes scabiei in human and animal populations. however, since scabies mites from different host species are indistinguishable morphologically, it is unclear whether people can be infected from scabies-infested animals. molecular fingerprinting was done using three s. scabiei-specific single locus hypervariable microsatellite markers, with a combined total of 70 known alleles. multilocus analysis of 712 scabies mites ... | 1999 | 10548286 |
