'Pinworms are in the family Oxiuridae. Oxyurids are noted for their close coevolution
with their hosts and their high degree of host specificity. Thus, oxyurid species tend to be
restricted in the number of hosts they infect and oxyruid phylogeny parellels the phylogeny of host
organisms. The life cycle of the human pinworm, E. vermicularis, is unique among
pinworms in its capacity for aerosol transmission. Aerosol transmission is achieved by the
desiccation and bursting of nocturanlly active females. Pinworm females exit the anus at night
and lay their eggs on the perianal folds. During this period, the females are subject to desiccation
due to air contact. The drying bodies of the females contract and eventually burst, showering
eggs into the air. Thus, pinworm females literally explode to dessiminate their eggs. The eggs E.
vermicularis are also highly evolved such that they are light and float in the air. The eggs are
nearly embryonated at the time of release.'
