VETERINARY MEDICINE: Dogs can be a potential risk for future influenza pandemic.

VETERINARY MEDICINE: Dogs can be a potential risk for future influenza pandemic. Dogs are a potential reservoir for a future influenza pandemic, according to a new study. The study demonstrated that influenza virus can jump from pigs into canines and that influenza is becoming increasingly diverse in canines. Influenza can jump among animal reservoirs where many different strains are located; these reservoirs serve as mixing bowls for the genetic diversity of strains. Pandemic influenza occurs when viruses jump from animal reservoirs to humans; with no prior exposure to the virus, most people do not have immunity to these viruses. The main animal hosts for influenza are wild birds, poultry and other domestic birds in a species pack; swine; and horses. Fifteen years ago, researchers documented an influenza virus in a horse jumping into a dog, and this created the first circulating canine influenza viruses. Five years ago, researchers identified an avian-origin H3N2 canine influenza virus circulating in farmed dogs in Guangdong, China.

Pandemic influenza occurs when viruses jump from animal reservoirs to humans; with no prior exposure to the virus, most people do not have immunity to these viruses. The main animal hosts for influenza are wild birds, poultry and other domestic birds in a species pack; swine; and horses. Some of the viral genes from the 2009 pandemic H1N1 virus originated in birds, from an avian virus that jumped to pigs, exchanged some of its genes with previously circulating swine viruses and then jumped from pigs into humans. Birds and swine are major reservoirs of viral genetic diversity, whereas equines and canines have historically been restricted to one or two stable influenza A viruses lineages with no or very limited transmission to humans.

EQUINE INFLUENZA UPDATE!!!

Equine influenza: Changing nature of cases!!! Cases are more common even in well-vaccinated horses, so what is the problem? The case of vaccine failure or vaccine break? Data from research on recent equine influenza virus (EIV) outbreaks show a noticeable change in the horses being affected by the virus.While naïve, young horses are still commonly affected, there has been a marked increase in EIV outbreaks among well vaccinated horses. This increase among well vaccinated horses is surprising and means we're seeing a lack of vaccine effectiveness," says Dr. Nicola Pusterla, professor of equine internal medicine at the University of California, Davis, School of Veterinary Medicine. "The recommendation here is for vaccines to include the most current influenza strain." To help keep EIV from affecting your horse's health, rely on a vaccine that has been updated to include the most relevant flu strains. Only Vetera® vaccines contain both the Florida Clade I and Clade II equine influenza strains as recommended by the OIE, a global panel that monitors circulating equine influenza strains, to protect against the strains most likely to infect horses today.

INFLUENZA IN HORSES.

Influenza caused by myxovirus,causing a respiratory disease that is severe in horses.All age groups are susceptible but foals are more susceptible,and its highly contagious. The mode of transmission is aerosol,usually from horse to horse. The common signs are fever,inappetence, watery nasal discharge,harsh dry cough.The disease is prevented by vaccination, isolate new horses and sick horses.
