Giardia protects its growth by reducing the formation of the gas nitric oxide by consuming all local arginine, which is the amino acid necessary to make nitric oxide. [7] Arginine starvation is known to be a cause of programmed cell death, and local removal is a strong apoptotic agent. [24]
Giardia (/ dʒ iː ˈ ɑːr d i ə / or / ˈ dʒ ɑːr d i ə /) is a genus of anaerobic flagellated protozoan parasites of the phylum Metamonada that colonise and reproduce in the small intestines of several vertebrates, causing the disease giardiasis.

If the cause is unknown, it is specified and called "simple pulmonary eosinophilia".

The cause of eosinopenia in COVID-19 infection is also unknown at this time. Some proposed contributory mechanisms include increased movement of eosinophils out of the blood into tissue, decreased generation or output of eosinophils from the bone barrow, and shorter lifespan within the blood. [ 3 ]
