Karst landscapes—regions characterized by sinkholes, caves, springs, underground rivers, and slowly dissolving bedrock— constitute about 25% of the world’s land surface (1). Although some karst landscapes are attractive and of aesthetic value, most of them are recognized as fragile zones unsuitable as human habitats— mainly due to extremely poor soil cover, or a complete lack of soil, and rapid...

Saccharum spontaneum is the most variable wild relative of sugarcane with potential for use in sugarcane improvement programs. In order to help preserve and exploit this species, 152 accessions from eight major geographical regions in China, including Hainan, Guangdong, Guangxi, Yunnan, Sichuan, Guizhou, Fujian, and Jiangxi provinces, were investigated by analyzing 20 simple sequence repeats (S...
BACKGROUND Hepatitis E virus (HEV) and caliciviruses are enteric pathogens of humans and animals, and pigs have been considered an important reservoir of these viruses. OBJECTIVES The aim of this study is to determine the infection rates of HEV and caliciviruses (sapovirus [SaV] and norovirus [NoV]) in different age groups of pigs in Guizhou province, China, and characterize the strains that ...
A new genus and species, Bambusimukaria quinquepunctata gen. & sp. n., feeding on bamboo in Guizhou and Fujian, China, are described and illustrated. The characters of crown, frontoclypeus, forewing venations and male genitalia place the new genus in the tribe Mukariini.
Two new species of Rhopalopsole Klapálek from China are described: Rhopalopsole exiguspina Du & Qian, sp. n. and Rhopalopsole ampulla Du & Qian, sp. n., which were collected in Guizhou province, China.
Shigella flexneri is one of the major etiologic causes of shigellosis in Guizhou Province, China. However, the genetic characteristics of circulating isolates are unknown. Phenotypic and molecular profiles of 60 S. flexneri isolates recovered in Guizhou between 1972 to 1982 and 2008 to 2010 were determined. Nine serotypes (1a, 2a, 3a, 1b, 2b, X, Y, 4av and Yv) were identified. Multi-locus seque...
