Experts with links to drugs industry 'hyped swine flu'
Conclusion This was a well-conducted study, albeit based on a small sample of articles. The finding that academics with ties to the drugs industry were more likely to make a higher assessment of risk from swine flu, and those promoting the use of antiviral drugs were more likely to have industry links, is worrying. The general issue of academics with undisclosed links to the pharmaceutical industry being interviewed by journalists is of concern. That said, the study does not prove that media coverage either fuelled public anxiety about swine flu or the policy decisions made about drug or vaccine funding. Similarly, the...

The Genetics of Life and Death: Virus-Host Interactions Underpinning Resistance to African Swine Fever, a Viral Hemorrhagic Disease
Conclusion and Future Perspectives The mechanisms which result in reduced viral replication and lack of disease in African wild suids after ASFV infection are largely unknown. The data so far indicate that this is not due to an intrinsic difference in the ability of the virus to replicate in macrophages from these hosts. A more likely explanation is that the innate immune system of these hosts is better able to control virus replication resulting in a reduced systemic infection and reduced pathogenesis. This may involve a balance between virus and host factors which has evolved over long term infections of these hosts. Se...

Swine flu jab narcolepsy risk is very small
Conclusion This study confirms that the Pandemrix vaccine against swine flu is associated with a very small risk of narcolepsy in children and young people. As the authors point out, this risk may have been overestimated if children with narcolepsy who had been vaccinated were more rapidly referred than others because of increased awareness of the link. The methods used were practical for a rapid assessment of risk, but as this was essentially a case series analysis they are limited by a number of factors: The rates calculated are dependent on the accurate diagnosis and identification of the cases of narcolepsy. By usin...

Recombinant Proteins of the Swine Hepatitis E Virus and Their Uses as a Vaccine and Diagnostic Reagents for Medical and Veterinary Applications
This invention is based on the discovery of the swine hepatitis E virus (swine HEV), the first animal strain of HEV identified and characterized, and its ability to infect across species. The inventors have found that the swine HEV is widespread in the general pig population in the United States and other countries and that swine HEV can infect non-human primates. The inventors have amplified and sequenced the complete genome of swine HEV. The capsid gene (ORF2) of swine HEV has been cloned and expressed in a baculovirus expression system.The possibility that swine HEV may infect humans raises a potential public health con...

Live poultry market workers are susceptible to both avian and swine influenza viruses, Guangdong Province, China
Publication date: Available online 25 September 2015 Source:Veterinary Microbiology Author(s): Jidang Chen, Jun Ma, Sarah K. White, Zhenpeng Cao, Yun Zhen, Shuyi He, Wanjun Zhu, Changwen Ke, Yongbiao Zhang, Shuo Su, Guihong Zhang Guangdong Province is recognized for dense populations of humans, pigs, poultry and pets. In order to evaluate the threat of viral infection faced by those working with animals, a cross-sectional, sero-epidemiological study was conducted in Guangdong between December 2013 and January 2014. Individuals working with swine, at poultry farms, or live poultry markets (LPM), and veterinaria...

Serological study of influenza viruses in veterinarians working with swine in Mexico
AbstractHumans and swine are both affected by influenza viruses, and swine are considered a potential source of new influenza viruses. Transmission of influenza viruses across species is well documented. The aim of this study was to evaluate the seroprevalence of different influenza virus subtypes in veterinarians working for the Mexican swine industry, using a hemagglutination inhibition test. All sera tested were collected in July 2011. The data were analysed using a generalized linear model and a linear model to study the possible association of seroprevalence with the age of the veterinarian, vaccination status, and bi...

Insulated Isothermal Reverse Transcriptase PCR (iiRT‐PCR) for Rapid and Sensitive Detection of Classical Swine Fever Virus
In this study, we describe validation of a new probe‐based insulated isothermal reverse transcriptase PCR (iiRT‐PCR) assay for rapid detection of classical swine fever virus (CSFV) on a compact, user‐friendly device (POCKIT™ Nucleic Acid Analyzer) that does not need data interpretation by the user. The assay accurately detected CSFV RNA from a diverse panel of 33 CSFV strains representing all three genotypes plus an additional in vitro‐transcribed RNA from cloned sequences representing a vaccine strain. No cross‐reactivity was observed with a panel of 18 viruses associated with livestock including eight other ...

Serological Evidence and Risk Factors for Swine Influenza Infections among Chinese Swine Workers in Guangdong Province
by Mengmeng Ma, Benjamin D. Anderson, Tao Wang, Yingan Chen, Dingmei Zhang, Gregory C. Gray, Jiahai Lu During July to September 2014, we performed a controlled, cross-sectional, seroepidemiologic study among 203 swine workers and 115 control subjects in Guangdong Province. Sera were tested using a hemagglutination inhibition assay against locally-isolated swine H3N2 and H1N1 viruses and commercially-obtained human influenza viral antigens. We found swine workers had a greater prevalence and odds of seropositivity against the swine H3N2 virus (17.3% vs. 7.0%; adjusted OR, 3.4; 95% CI, 1.1 -10.7). Younger age, self-report o...

Flu Season Now As Bad As 2009 Swine Flu
NEW YORK (AP) — The flu has further tightened its grip on the U.S. This season is now as bad as the swine flu epidemic nine years ago. A government report out Friday shows 1 of every 13 visits to the doctor last week was for fever, cough and other symptoms of the flu. That ties the highest level seen in the U.S. during swine flu in 2009. And it surpasses every winter flu season since 2003, when the government changed the way it measures flu. “I wish that there were better news this week, but almost everything we’re looking at is bad news,” said Dr. Anne Schuchat, acting director of the Centers for Disea...

Classical swine fever: challenges for the emerging swine sector in Bhutan
AbstractGiven the importance of pork in the Bhutanese diet and to enhance food security, the Government of Bhutan has generated policies to promote development of the swine sector in the country. One of the main threats to swine farming is classical swine fever (CSF), a transboundary disease of wild and domestic swine thought to be enzootic in the country. In 2018, three outbreaks of CSF were notified in Bhutan. The type of animals, their vaccine status, and the aftermath of these outbreaks highlight the interplay of epidemiological and context-specific factors that may result in CSF undermining the emerging Bhutanese swin...

C-reactive protein, haptoglobin, serum amyloid A and pig major acute phase protein response in pigs simultaneously infected with H1N1 swine influenza virus and Pasteurella multocida
Conclusions: The results of current study confirmed that monitoring of APP may revealed ongoing infection, and in this way may be useful in selecting clinically healthy pigs (i.e. before integration into an uninfected herd). Present results corroborated our previous findings that SAA could be a potentially useful indicator in experimental infection studies (e.g. vaccine efficiency investigations) or as a marker for disease severity, because of correlation observed between its concentration in serum and disease severity (lung scores, clinical scores).

The role of noncoding regions of classical swine fever virus C-strain in its adaptation to the rabbit.
Abstract Classical swine fever (CSF) is a devastating disease of swine caused by classical swine fever virus (CSFV). C-strain, a modified live vaccine against CSF, was developed through hundreds of passages of a highly virulent CSFV in the rabbit in China in the mid-1950s. To identify the role of noncoding regions (NCRs) of C-strain in its adaptation to the rabbit, we generated and evaluated a series of chimeric viruses derived from C-strain and the highly virulent Shimen strain. The results demonstrated that the NCRs of the C-strain were essential for its fever induction in rabbits and the coding region but not N...
