Swine Influenza Virus: Zoonotic Potential and Vaccination Strategies for the Control of Avian and Swine Influenzas

Read the veterinary literature on swine flu and you get a strong sense of what might be called vaccination treadmill: the hog industry is literally scrambling to generate new vaccines for the rapidly evolving flu strains that sweep through CAFOs. Writing in the Journal of Infectious Diseases [PDF] in 2008, Eileen Thacker and Bruce Janke of Iowa State University paint a stark picture: “A number of genetically diverse viruses are circulating in swine herds throughout the world and are a major cause of concern to the swine industry,” they write. “Influenza virus infections in swine and poultry are potential sources of viruses for the next pandemic among humans.”

Irving Nachamkin, a professor of pathology and laboratory medicine at the University of Pennsylvania, examined some 1976 vaccine that had been saved by a scientist in Texas. In a paper published last year in The Journal of Infectious Diseases, he and colleagues reported that mice given the vaccine made antibodies that reacted with gangliosides, which are components of nerve cells. An antibody attack on gangliosides is part of the disease mechanism of Guillain-Barré.

Last year researchers from Iowa State University in Ames warned that pigs located in industrial-scale farms were being subjected to influenza infections from farm poultry, wild birds and their human handlers. Writing in The Journal of Infectious Diseases, Eileen Thacker and Bruce Janke said, "As a result of the constantly changing genetic makeup of individual influenza viruses in pigs, the U.S. swine industry is continually scrambling to respond to the influenza viruses circulating within individual production systems."

Background.Severe anemia (hemoglobin level, <50 g/L) is a major cause of death among young children, and it arises from multiple factors, including malaria and iron deficiency. We sought to determine whether infection with parvovirus B19 (B19), which causes the cessation of erythropoiesis for 3–7 days, might precipitate some cases of severe anemia.

Methods.Archival blood samples collected in the Wosera District of Papua New Guinea, from 169 children 6 months–5 years old with severe anemia and from 169 control subjects matched for age, sex, and time were tested for B19 immunoglobulin M (IgM) by enzyme immunoassay and for B19 DNA by nested polymerase chain reaction (PCR). A total of 168 separate samples from children in the Wosera District were tested for B19 IgG.

Results.A strong association between acute B19 infection (positive by both IgM and PCR) and severe anemia was found (adjusted odds ratio, 5.61 [95% confidence interval, 1.93–16.3]). The prevalence of parvovirus B19 IgG reached >90% in 6‐year‐olds.

Conclusions.B19 infections play a significant role in the etiology of severe anemia in this area of malarial endemicity. Given the high levels of morbidity and mortality associated with severe anemia in such regions, the prevention of B19 infection with a vaccine might be a highly effective public health intervention.
