2009 H1N1 Influenza Virus Seroepidemiology

Influenza A virus among the hospitalized young children with acute respiratory infection. Is influenza A co infected with respiratory syncytial virus?

Background: Both influenza A virus (IAV) and respiratory syncytial virus (RSV) cause acute respiratory infection (ARI) in infants and young children. This study was conducted to determine Influenza A virus and its co infection with RSV among the hospitalized children with ARI. Methods: A total of 153 throat samples of the hospitalized young children aged between below one year and 5 years with...

Influenza virus nucleoprotein interacts with influenza virus polymerase proteins.

Influenza virus nucleoprotein (NP) is a critical factor in the viral infectious cycle in switching influenza virus RNA synthesis from transcription mode to replication mode. In this study, we investigated the interaction of NP with the viral polymerase protein complex. Using coimmunoprecipitation with monospecific or monoclonal antibodies, we observed that NP interacted with the RNP-free polyme...

Analytical sensitivity of rapid influenza antigen detection tests for swine-origin influenza virus (H1N1).

BACKGROUND A novel swine origin influenza virus (S-OIV) (H1N1) is spreading worldwide and threatens to become pandemic. OBJECTIVES Determine analytical sensitivity of selected commercially available rapid influenza antigen detection tests in detecting S-OIV H1N1. STUDY DESIGN Serial dilutions of two S-OIV isolates, one seasonal influenza A (H1N1) isolate and a nasopharyngeal aspirate from a...
