Paepalanthus rectifolius, a new name in Eriocaulaceae (Poales)

A careful analysis reveals that this variety has dimerous flowers, free petals of the pistillate flower and bifid stigmatic branches. It is therefore misplaced in Syngonanthus Ruhland (1900). We transfer it to Paepalanthus Mart. (1834) at the species level, as it is distinct from morph...

Clinical and Molecular Epidemiology of Staphylococcus argenteus Infections in Thailand

Molecular typing of 246 Staphylococcus aureus isolates from unselected patients in Thailand showed that 10 (4.1%) were actually Staphylococcus argenteus. Contrary to the suggestion that S. argenteus is less virulent than S. aureus, we demonstrated comparable rates of morbidity, death, and health care-associated infection in patients infected with either of these two species.
