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.”

Anti‐Ganglioside Antibody Induction by Swine (A/NJ/1976/H1N1) and Other Influenza Vaccines: Insights into Vaccine‐Associated Guillain‐Barré Syndrome

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.

The vaccine Mittal created for the bird flu worked on three different strains isolated over a seven-year period and was described in papers for the Journal of Infectious Diseases and the journal Clinical Pharmacology and Therapeutics.

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

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."

Oxidative stress contributes to hepatitis C virus (HCV)–induced liver damage. The activity of antioxidant glutathione S‐transferases (GSTs) T1 and M1 is polymorphic. The GSTT1 and GSTM1 genotypes were identified in 139 HCV‐infected patients and in 329 healthy individuals. Among patients, there was an excess of GSTT1 (odds ratio [OR], 2.76 [95% confidence interval {CI}, 1.77–4.30]; ) and GSTM1 (OR, 1.54 [95% CI, 1.02–2.35]; ) null genotypes and of double‐null haplotypes (OR, 3.65 [95% CI, 1.98–6.75]; ). The GSTT1 null genotype, particularly if associated with the GSTM1 null genotype, may facilitate HCV infection becoming chronic.
