We examined risk factors associated with Necator americanus infection among persons aged > or =50 years in Hainan Province, People's Republic of China. Age and sex made the most important contributions to the variation in infection intensity (28%-30%), with age alone responsible for 27% of this variation. When stratified by 20-year age intervals, the influence of shared residence was 23% for pe...

One genus and species are synonymized in the tribe Empoascini of the subfamily Typhlocybinae. Bhatasca Dworakowska, 1995is a junior synonym of Alebrasca Hayashi & Okada, 1994, Bhatasca rectangulata Qin & Zhang, 2011is a junior synonym of Alebrasca actinidiae Hayashi & Okada, 1994. Furthermore, Bhatasca expansa is (necessarily) transferred to the genus Alebrasca.

The main objective of the present study is to assess and improve fermentation conditions produce polyhydroxyalkanoates (PHAs), such as homopolymer poly(3-hydroxybutyrate) (PHB) copolymer poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), from renewable inexpensive industrial waste by wild type Cupriavidus necator. Untreated residual glycerol, a byproduct generated biodiesel industry, was used...

A powdery mildew was found associated with the coastal wattle, Acacia sophorae, at Tullymorgan, in northern New South Wales, Australia. Morphological characterisation identified it as belonging to genus Erysiphe, while internal transcribed spacer (ITS) sequencing and phylogenetic analysis confirmed Erysiphe quercicola, a pathogen worldwide distribution broad host range. This is first record of ...
