parenchyma of the liver, and the lung and
several were in fibrous capsulesattached to the
mesentery.
Closer examination on the dissecting microscope revealed 20 pronounced annulations on
each of the organisms and an oral orifice was
located on the ventral surface close to the anterior tip, flanked laterally by a pair of recurved
hooks. These organisms were identified as
“ymphs of Armillifer

from its

since none of the other
3 chimpanzees
living in the same cage with the
deceased one showed any sign of infection.
The public health importance
of this pentastome cari be significant
especially in localities
where apes are eaten by humans.
This finding in a zoo chimpanzee
adds yet another host on record in the West of Africa.
Although
A. armillatus
has not yet been
reported
in chimpanzee,
its occurrence
in this
host is not unexpected
considering
its wide
host range.
SUMMARY
Nymphal staga of Armill~~er armillatus
were found encapsulated in the
organs of a captive chnnpanree from the Kane St& Zoo. The Chimpanzee is
recorded as a new host in this region.
