Samples collected from bird droppings in Central Park are examined for pathogens like bird flu and avian paramyxovirus - a virus that only affects poultry, and researchers recently detected avian ...
Hypersensitivity pneumonitis (HP) or extrinsic allergic alveolitis (EAA) is a syndrome caused by the repetitive inhalation of antigens from the environment in susceptible or sensitized people. [1] [2] Common antigens include molds, bacteria, bird droppings, bird feathers, agricultural dusts, bioaerosols and chemicals from paints or plastics. [3]
After the current strain of bird flu, H5N1, reached the U.S. in 2022, more than 148 million birds have been euthanized. What is the outbreak's potential impacts on humans, the poultry industry ...
