Hemolysin III drives neuroinvasion and meningitis while impacting desiccation resilience in .

Unlabelled: is an emerging pathogen associated with severe neonatal diseases, including meningitis. Its ability to cross the blood-brain barrier (BBB) is critical for meningitis development, yet the underlying mechanisms remain unclear. This study investigates the role of Hemolysin III (Hly III), encoded by the , in neuroinvasion and environmental resilience.

Biological characteristics and conjugated antigens of ClfA A-FnBPA and CP5 in .

To obtain immunogenic conjugate antigens, adipic acid dihydrazide (ADH), as a bridge, and 1-ethyl-3-(3-dimethylaminopropyl) carbodiimidehydrochloride (EDAC), as a coupling agent, were used to conjugate the purified fusion protein, clumping factor A-fibronectin binding protein ClfA A-FnBPA, and type 5 capsular polysaccharide (CP5). The conjugates were mixed with an adjuvant, and mice were immunized 3 times and challenged with 1 week later. Antibody titers were determined by indirect enzyme-linked immunosorbent assay (ELISA).

Updated incidence rates and risk factors of esophageal cancer in Nan'ao Island, a coastal high-risk area in southern China.

Esophageal cancer (EC) is one of the most common cancers in China. The purpose of this study was to investigate the updated incidence rates and risk factors of EC in Nan'ao Island, where the EC incidence rate was chronically the highest in southern China. To calculate the annual incidence rate, data on 338 EC cases from Nan'ao Cancer Registry system diagnosed during 2005-2011 were collected.
