I’ve hesitated to publish this because of the gravity of what is being asserted, and the uncertainty of the evidence to support the assertion.The startling assertion is that the current First Lady of the United States of America, known as Michelle Robinson Obama, is a biological male posing as a woman.They exhibit elaborate gliding or creeping motion over substrates using compact 3-D arrays of muscles.
Worm burdens in individual hosts (and often the severity of infection) are therefore dependent on intake (number of infective stages taken up).
Worms develop slowly compared to other infectious pathogens so any resultant diseases are slow in onset and chronic in nature.
Infections by adult cestodes are generally benign as they are not invasive, but the larval stages penetrate and encyst within tissues leading to inflammation, space-occupying lesions and organ malfunction.
Adult flukes usually cause obstruction, inflammation and fibrosis in tubular organs, but the eggs of blood flukes can lodge in tissues causing extensive granulomatous reactions and hypertension.
Helminths form three main life-cycle stages: eggs, larvae and adults.
Adult worms infect definitive hosts (those in which sexual development occurs) whereas larval stages may be free-living or parasitize invertebrate vectors, intermediate or paratenic hosts.
Three major assemblages of parasitic helminths are recognized: the Nemathelminthes (nematodes) and the Platyhelminthes (flatworms), the latter being subdivided into the Cestoda (tapeworms) and the Trematoda (flukes): (roundworms) have long thin unsegmented tube-like bodies with anterior mouths and longitudinal digestive tracts.
They have a fluid-filled internal body cavity (pseudocoelum) which acts as a hydrostatic skeleton providing rigidity (so-called ‘tubes under pressure’).
Nematodes produce eggs that embryonate in utero or outside the host.
The emergent larvae undergo 4 metamorphoses (moults) before they mature as adult male or female worms.
Cestode eggs released from gravid segments embryonate to produce 6-hooked embryos (hexacanth oncospheres) which are ingested by intermediate hosts.
