Dramatic crustal deformation and river incision in Southwest China induced by the Indo-Asian collision have long been argued to contribute to the complicated landscapes, heterogeneous environment and abundant biodiversity in this region. However, biological impacts in promoting intraspecific phylogeographical subdivision and divergence along the Red River Fault zone (RRF) remain poorly understo...

Duck beak atrophy and dwarfism syndrome (BADS) is a newly emerged disease in China since 2015. In October 2017, an unidentified disease occurred in Cherry Valley ducks, Chongqing municipality, the southwest of China. The affected birds showed short beak and growth retardation clinical signs. The disease caused approximately 20.00% morbidity and serious weight loss due to retarded growth. In ord...

Population migrations in Southwest and South China have played an important role in the formation of East Asian populations and led to a high degree of cultural diversity among ethnic minorities living in these areas. To explore the genetic relationships of these ethnic minorities, we systematically surveyed the variation of 10 autosomal STR markers of 1,538 individuals from 30 populations of 2...

BACKGROUND The changing pattern of hepatitis C virus (HCV) infection could have a significant impact on future medical prevention practices and therapies. OBJECTIVES The purpose of this study was to describe the changing pattern of HCV infection in southwest China using clinical epidemiology, and to assess the association between the genotypes distribution and certain potential risk factors. ...

OBJECTIVE To study the human migration inhibitory factor (MIF) level in tuberculosis (TB) patients, and the relationship between MIF-794CATT microsatellite polymorphism and susceptibility of TB in Southwest China. METHODS TB patients (n=151) and healthy unrelated controls (n=149) were recruited for this study. Genomic DNA was extracted, and then amplified by polymerase chain reaction (PCR). M...

Fifty-five wild accessions of bermudagrass (Cynodon dactylon) were collected from southwest China (Sichuan, Chongqing, Yunnan, Guizhou, and Tibet), and their genetic diversity was analyzed using simple sequence repeat markers. A total of 267 polymorphic bands were detected with 18 primer combinations. The genetic similarity among the accessions ranged from 0.688 to 0.894 with an average of 0.79...
