A model for emergence of high pathogenicity avian influenza virus from outbreaks with low pathogenicity avian influenza virus
In this article, we establish a mathematical model for emergence of high pathogenicity avian influenza (HPAI) viruses from outbreaks of low pathogenicity avian influenza (LPAI) A viruses (H5N2). The model is based on traditional mathematical epidemiology models and experiment evidences. It contains several submodels which are traditional SEIR models or SIR models. The experiments in [25] provid...
متن کاملSuper-Sentinel Chickens and Detection of Low-Pathogenicity Influenza Virus
Chicken interferon-alpha administered perorally in drinking water acts on the oropharyngeal mucosal system as an adjuvant that causes chickens to rapidly seroconvert after natural infection by low-pathogenicity Influenza virus. These chickens, termed super sentinels, can serve as sensitive early detectors of clinically inapparent infections.
متن کاملThe onset of virus shedding and clinical signs in chickens infected with high-pathogenicity and low-pathogenicity avian influenza viruses.
Some avian influenza viruses may be transmissible to mammals by ingestion. Cats and dogs have been infected by H5N1 avian influenza viruses when they ate raw poultry, and two human H5N1 infections were linked to the ingestion of uncooked duck blood. The possibility of zoonotic influenza from exposure to raw poultry products raises concerns about flocks with unrecognized infections. The present ...
متن کاملGenetically Diverse Low Pathogenicity Avian Influenza A Virus Subtypes Co-Circulate among Poultry in Bangladesh
Influenza virus surveillance, poultry outbreak investigations and genomic sequencing were assessed to understand the ecology and evolution of low pathogenicity avian influenza (LPAI) A viruses in Bangladesh from 2007 to 2013. We analyzed 506 avian specimens collected from poultry in live bird markets and backyard flocks to identify influenza A viruses. Virus isolation-positive specimens (n = 50...
متن کاملProlonged excretion of a low-pathogenicity H5N2 avian influenza virus strain in the Pekin duck
H5N2 strains of low-pathogenicity avian influenza virus (LPAIV) have been circulating for at least 17 years in some Mexican chicken farms. We measured the rate and duration of viral excretion from Pekin ducks that were experimentally inoculated with an H5N2 LPAIV that causes death in embryonated chicken eggs (A/chicken/Mexico/2007). Leghorn chickens were used as susceptible host controls. The d...
