Under experimental conditions, close to 100 percent of healthy chickens vaccinated with available commercial NDV vaccines can survive an infection with virulent
The new disease, downy mildew of aquilegias, is very virulent
and with no chemical control it is killing plants.
The lab, based in Wuhan, capital city of central Hubei Province, will be used to study class four pathogens (P4), which refers to the most virulent
viruses that pose a high risk of aerosoltransmitted persontoperson infections, Xinhua reported.
So a highly virulent
disease runs the risk of killing or debilitating its hosts before they get a chance to pass the bug along.
As they explained that the strain is a previously unseen variant of the bacterium and one that is more virulent
than before, US scientists, in opposition to Europeans, are now warning that the new strain appears to be resistant to common antibiotics.
The question is whether it's still virulent
enough to cause serious listeriosis infections, as its uninjured counterparts can.
strain of Clostridium difficile (C diff) has been detected in Australia for the first time.
The hyper virulent
strain of Clostridium difficile has been identified in Australia, after Epworth Healthcare in Richmond, Victoria, reported it had managed three patients diagnosed with the strain since February this year.
Fast-tracking of the vaccine before the bug becomes more virulent
should see everyone protected by next year.
Experts are already drawing up a priority list of patients to be given immunity before the bug becomes more virulent
The disease is virulent
systemic feline calicivirus (VS-FCV), a highly contagious and potentially fatal mutation of traditional calicivirus.
Extensive molecular research showed that this isolate belonged to the highly virulent
AFLP genotype 6A (VGIIa) of Cryptococcus gattii, which is the major genotype involved in the Vancouver Island C.
