Pat Nuttall laboratory reagent, a result that was published in "Nature" in 1977. She then worked with ornithologist Chris Perrins trying to identify the virus responsible for puffinosis, a disease that affects the Manx shearwater ("Puffinus puffinus") sea bird. During this research, Nuttall visited sea-bird colonies and became interested in ticks, arthropods that often infest sea birds as well as other vertebrates, and can act as vectors for disease. In the early 1980s, Nuttall started to study viruses transmitted by ticks, initially focusing on orbiviruses, nairoviruses and thogotoviruses. While performing experiments designed to explore whether "Thogoto virus", an influenza-like virus, can be
Bird extinction which results to the downfall of extinction. The most common disease affecting birds is Salmonellosis, which originates from the Latin name of salmonella. Infected birds pass bacteria in their fecal droppings. Other birds then become ill when they eat food contaminated by the droppings. Bird extinction Out of the approximately 10,400 known bird species, about 1,300 (13%) are classified as threatened with extinction, 9% as near threatened and of the remaining 78% many populations are declining. There is a general consensus among scientists who study these trends that if human impact on the environment continues as it has one-third of
