[Investigation of two blood parasitic protozoa infection in farmed in Guangxi Zhuang Autonomous Region].

Objective: To investigate the infection situation of blood parasitic protozoa in farmed in an animal breeding ground in Nanning, Guangxi Zhuang Autonomous Region, so as to provide the evidence for the prevention and control of human blood parasitic protozoa.

Methods: A total of 993 blood samples from farmed were collected and stored on FTA cards. Among them, 550 thin blood smears were made.

Oral respiratory syncytial virus (RSV) DNA vaccine expressing RSV F protein delivered by attenuated Salmonella typhimurium.

Human respiratory syncytial virus (RSV) is a major viral pathogen of the lower respiratory tract of infants and young children worldwide. No effective prevention measure is available. Attenuated Salmonella strains expressing heterologous antigens can be delivered by the oral route, triggering efficient antigen-specific humoral, cellular, and mucosal immunity.
