EAZWV Transmissible Disease Fact Sheet Sheet No. 124
Fact sheet compiled by
Last update
Manfred Brack, formerly German Primate Center, Göttingen / Germany.
Susceptible animal groups
Mainly Old World nonhuman primates, man.
Causative organism
Strongyloides stercoralis, S.fülleborni, S.cebus.
Zoonotic potential
World- wide, preferentially in subtropical and tropical regions.
Percutaneously. The adult Strongyloides females live in the large intestines of the host animals (or man!),
produce embryonated eggs, which in S.fülleborni and S.cebus are faecally excreted as such, whereas in
the larvae may hatch already in the original hosts large intestine, thus causing autoinfections.
In the other Strongyloides spp. the larvae hatch in the environment, proceed through 2 molts to reach the
infective filariform larval stage or to develop into free-living male and female adults, which start one or more
new external larval cycles. Both the directly and the indirectly generated filariform larvae penetrate the skin,
or at being swallowed, the epithelia of the upper digestive tract. Subsequently they migrate via the circulation
to the lung, burrow through the alveolar capillaries and alveolar walls, migrate actively up to the larynx and
pharynx, are swallowed and ,on reaching the small intestine of the new host become again adult
embryonated eggs producing females. Migrating larvae may cross the placental tissues, thus leading to
infections already od newborn apes. That migration stage, regardless of the Strongyloides- species involved,
applies to only a precentage of infecting larvae. The others convert to a resting stage somewhere in the new
hosts tissues after epithelial penetration, surviving there for decades and eventually becoming reactivated
after stress (pregnancy, social stress etc.).
Incubation period
Prepatent period: 11 – 18 days.
Clinical symptoms
The skin-penetrating larvae cause itching sensations, and eventually urticaria, those burrowing through the
lung dyspnea, cough or even pneumonia. The adults living in the small intestine cause haemorrhagic-mucoid
diarrhea, anorexia, vomitus, depression, weight loss and occasionally paralytic ileus.
Post mortem findings
Multifocal or diffuse pulmonary haemorrhages, catarrhal to haemorrhagic- necrotic enterocolitis. In
hyperinfections subacute eosinophilic interstitial pneumonia, eosinophilic vasculitis and perivasculitis.
Repeated ovodiagnosis in S. fülleborni/S. cebus infestations, repeated larval demonstrations in S.stercoralis
infestations of great apes and man, using Baerman Wetzel funnels. In necropsies of great apes larval
emigration tests from the duodenal tissues and histological examination of the duodenum are advisable

When Doing Everything We Know is Not Enough At three, Sam drank kerosene from a used “Mountain Dew” can. As a toddler he had his clothes stapled to the floor as a means of control or cruelty or deranged parenting. At four, Sam is expelled from kindergarten for a host of reasons including wiping feces on school bus windows. He was the youngest of five siblings and the sex toy for older yo
