Project Wildlife proactive towards Newcastle and WNV
By Jane E. Meier, DMV
West Nile Virus-West Nile virus (WNV) is a viral disease spread by
mosquitoes that bite and infect humans and other animals. It has been
spreading from the East Coast toward California over the last few
years. West Nile virus can cause serious disease and death in wildlife
and may have a significant impact on our rehabilitation efforts. In
preparing for its arrival Project Wildlife is participating in WNV
surveillance.
Project Wildlife asks volunteers with any dying or deceased crows,
ravens, jays, raptors, blackbirds, finches, sparrows, or cowbirds immediately
to report the birds to the California WNV hotline 1-877-WNVBIRD
(1-877-968-2473). Time is of the utmost importance in recovering
the virus, so call the toll free number as soon as possible. Do not delay
calling, and submit all eligible birds. Birds dead more that 24 hours
(gross decomposition, maggots, desiccated eyes or body) cannot be
used. Do not call the hotline for these birds or birds that die over the
weekend. The virus will not be detectable.
The target species of birds (crows, ravens, jays, raptors, blackbirds,
finches, sparrows, or cowbirds) can have high levels of WNV in their
bloodstream. These species should be handled with gloves. Blood from
a potentially infected bird should not come in contact with your skin.
You may have scrapes and cuts which might be an avenue of infection.
Wash your hands frequently in addition to wearing gloves.
Mammals are considered "dead end hosts". Mammals can be infected
by mosquitoes, but they do not transmit the virus to others. Project
Wildlife is planning to vaccinate our education animals for WNV this
spring when the mosquito population starts to rise. We will be using
the WNV vaccine developed for use in horses. Several zoos and wildlife
groups are testing the vaccine on their animals. Project Wildlife is
going to see if there are any ill effects from the vaccine before we use
it on our animals. Even if the vaccine has no side effects, no one
knows if the vaccine will provide protection to non-equine
species.
Newcastle Disease - An outbreak of Newcastle disease at a
chicken ranch in eastern Ramona has been diagnosed. At this
point, 73,000 chickens have been euthanized. It is most likely
that the ranch in Ramona was infected by incompletely sanitized
egg handling equipment from an infected ranch in the Los
Angeles area. San Diego County is now under a Newcastle
disease quarantine.
Newcastle disease is a highly contagious viral disease of all
species of birds. It is spread by direct contact with bodily fluids
from infected birds and can be carried on shoes, clothing,
equipment, etc. It can cause a variety of signs and kills many of
the birds that are infected. There is a vaccine for Newcastle
disease, but it is only safe in poultry.
The disease is not native to the United States and because of
its potential harm to the poultry industry, infected birds are euthanized. The chances of Newcastle disease becoming established
in the wild bird population is EXTREMELY low. In the last
outbreak in San Diego in 1978, it did not spread to any wild
birds.
To ensure the safety of Project Wildlife's education birds, PW
has instituted several precautionary measures. Until further
notice, we will not hold any education programs within the
Ramona area nor attend any education events if other birds will
be present. We are eliminating avenues of contact between
education birds and rehab birds. This means that the caretakers
of our bird ambassadors will not accept birds for rehabilitation.
Further we are keeping education bird enclosures protected
from wildlife visitors.
