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."

Herpes simplex virus type 2 (HSV‐2) resistance to antiviral drugs has been described primarily in immunocompromised patients. We report an apparently immunocompetent, human immunodeficiency virus–negative male patient who has experienced repeated HSV‐2 genital outbreaks despite receiving antiviral prophylaxis with several different drugs. Several of the HSV‐2 genital isolates from this patient have been confirmed as resistant to acyclovir and penciclovir. Antiviral resistance occurred in the setting of long‐term prednisone treatment and intermittent acyclovir prophylaxis at suboptimal doses and persisted despite the cessation of oral steroid treatment. The patient’s genital herpes outbreaks were not controlled by high‐dose prophylaxis with acyclovir, valacyclovir, and famciclovir. Cessation of antiviral prophylaxis resulted in reversion of this patient’s HSV‐2 isolates to acyclovir and penciclovir sensitivity, although resistant virus reappeared when antiviral prophylaxis was resumed. Transmission of a sensitive HSV‐2 strain from this patient to a female sex partner was observed. These observations confirm previous reports that resistance to acyclovir may develop during prophylactic therapy in an otherwise well, immunocompetent patient. These findings support the conclusion that both drug‐sensitive and drug‐resistant HSV‐2 strains established latency in this patient and that both strains are capable of frequent reactivation.
