[2] [3] Symptoms of this infection vary greatly, but the disease affects primarily the lungs. [4] Occasionally, other organs are affected; called disseminated histoplasmosis, it can be fatal if left untreated. H. capsulatum is found in soil, often associated with decaying bat guano or bird droppings. Disruption of soil from excavation or ...
Histoplasma capsulatum is a species of dimorphic fungus.Its sexual form is called Ajellomyces capsulatus.It can cause pulmonary and disseminated histoplasmosis.. Histoplasma capsulatum is "distributed worldwide, except in Antarctica, but most often associated with river valleys" [1] and occurs chiefly in the "Central and Eastern United States" [2] followed by "Central and South America, and ...
BFL is caused by an immune response to inhaled allergens from birds, [3] which induce a type III hypersensitivity reaction through the formation of immune complexes within the lung parenchyma. [5] This may be the dry dust of droppings, or feathers. These antigens can come from any bird. [1] BFL may be caused by allergens from pigeons.
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]
There are two primary types of dust exposure in agriculture: inorganic and organic. Often the cause of allergy illnesses like asthma, organic dusts come from both plant and animal sources. Inorganic dust illnesses are non-allergic lung reactions that originate in the soil. [4] Asthma-like symptoms are linked to inorganic dust syndrome.
Birds are infected once they ingest the eggs of the nematode in soil, or sometimes through earthworms which had ingested the egg-contaminated soil. Outbreak can occur rapidly from the heavily infected bird in a flock readily through normal contact between uninfected and infected birds and their droppings in the total absence of cecal worms .

Psittacosis—also known as parrot fever, and ornithosis—is a zoonotic infectious disease in humans caused by a bacterium called Chlamydia psittaci and contracted from infected parrots, such as macaws, cockatiels, and budgerigars, and from pigeons, sparrows, ducks, hens, gulls and many other species of birds. The incidence of infection in ...
Sporotrichosis, also known as rose handler's disease, [2] is a fungal infection that may be localised to skin, lungs, bone and joint, or become systemic. [2] [4] It presents with firm painless nodules that later ulcerate. [3] Following initial exposure to Sporothrix schenckii, the disease typically progresses over a period of a week to several ...
