Introduction: Influenza A virus causes unpredictable epidemics and pandemics by creating antigenic variations. With the appearance of each new strain, rapid emergency countermeasures are taken against this new strain. Hence, designing an applicable and cross protective strategy to counter this virus is of great importance. To achieve this, choosing conserved antigenic regions in influenza virus...
Introduction: Avian influenza viruses are considered as a serious threat to human and animal health. An increase in expression of proinflammatory cytokines and type I IFN genes, as well as host cell death responses contribute to the pathogenesis of influenza infection. Hence, this study aimed to evaluate the growth dynamics of subacute avian influenza virus in human respiratory alveolar epithel...
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 ...
BACKGROUND Influenza data gaps in sub-Saharan Africa include incidence, case fatality, seasonal patterns, and associations with prevalent disorders. METHODS Nasopharyngeal samples from children aged <12 years who were admitted to Kilifi District Hospital during 2007-2010 with severe or very severe pneumonia and resided in the local demographic surveillance system were screened for influenza A...
L-ascorbic acid (vitamin C) is one of the well-known anti-viral agents, especially to influenza virus. Since the in vivo anti-viral effect is still controversial, we investigated whether vitamin C could regulate influenza virus infection in vivo by using Gulo (-/-) mice, which cannot synthesize vitamin C like humans. First, we found that vitamin C-insufficient Gulo (-/-) mice expired within 1 w...
The spread of influenza viruses in multiple bird and mammalian species is a worldwide serious threat to human and animal populations' health and raise major concern for ongoing pandemic in humans. Direct transmission of the avian viruses which have sialic acid specific receptors similar to human influenza viruses are a warning to the emergence of a new mutant strain that is likely to share mole...
Background and Aims: Influenza is an acute respiratory illness that is caused by a virus belonging to Orthomyxoviridae family. This virus spreads rapidly every year in cold season and leads to morbidities and mortalities especially in adults and children, which causes billions of dollars of economic losses. Accordingly, development of a rapid, sensitive and inexpensive laboratory diagnosis base...
Ouinea pigs exposed by the respiratory route to sublethal doses of influenza virus, PR8 strain, resisted subsequent challenge with a lethal doso of Coxiella burnetti administered by the same route. This note describes this interference phenomenon. PRECEDING PAGE BLANK 5 INTERFERENCE WITH COXIELIA BURNETII INFECTIONS OF GUINEA PIGS BY INFLUENZA A VIRUS Guinea pigs* exposed by the respiratory rou...
Human coronavirus OC43 and bovine coronavirus elute from agglutinated chicken erythrocytes when incubated at 37 degrees C, suggesting the presence of a receptor-destroying enzyme. Moreover, bovine coronavirus exhibits an acetylesterase activity in vitro using bovine submaxillary mucin as substrate similar to the enzymatic activity found in influenza C viruses. Furthermore, pretreatment of eryth...
