context_page_description: Arthroconidia are a type of fungal spore typically produced by segmentation of pre-existing fungal hyphae.
  These spores are asexual and are generally not as durable and environmentally persistent as, for instance, bacterial endospores or chlamydospores. Some medically significant pathogens, such as Coccidioides immitis, and Coccidioides posadasii, both causative agents of coccidioidomycosis, are transmitted through airborne arthroconidia. The small size of the arthroconidia, 3 to 5 µm, allow them to lodge themselves into the terminal bronchioles of the lung. There, they develop into a thick-walled spherule filled with endospores that cause a pyogenic inflammation.

Some medically significant pathogens, such as Coccidioides immitis, and Coccidioides posadasii, both causative agents of coccidioidomycosis (also known as San Joaquin Valley fever), are transmitted through airborne arthroconidia. The small size of the arthroconidia, 3 to 5 µm, allow them to lodge themselves into the terminal bronchioles of the lung. There, they develop into a thick-walled spherule filled with endospores that cause a pyogenic (pus-causing) inflammation.
