S. flexneri (types

dysenteriae are the most common organisms causing
problems in primates. Humans are considered their main
dysentery is often mistaken as EIEC (enteroinvasive
E. coli). Five
recognized classes of enterovirulent
(collectively referred to as the EEC group) cause
gastroenteritis in humans. Although
E. coli is
considered part of the normal intestinal flora of humans and
other primates, a minority of
E. coli strains are
capable of causing illness in human and primates by several
different mechanisms. Among these are the enteroinvasive (EIEC)
Shigella and EIEC
are transmitted through the fecal-oral route, through
contaminated food or water or by direct contact, aerosol, or
mechanical vectors such as flies. The organisms are shed from
both clinically ill and asymptomatic humans and primates. Even
minimal contact is adequate for transmission.
primates by these bacteria usually results in a subclinical
carrier state, but disease may then be induced by stress. Signs
include watery to bloody diarrhea, weakness, and edema of the
face and neck. Rectal prolapse is common. High mortality can
result from Shigellosis in primates. Recovered animals are often
carriers and can act as a reservoir of infection.
blood culture with selective media is sometimes used to identify
Shigella and enteroinvasive
E. coli. However, microbiological culture is slow and not
very sensitive. Molecular detection of these bacteria is highly
sensitive and specific, and is also highly tolerant of
suboptimal specimen shipping and handling conditions that would
invalidate other testing methods.
