Abstract
Tongue and diaphragm samples were collected from a
total of 620 pigs slaughtered at different locations in
Kaduna State of Nigeria, and 240 randomly trapped brown
field rats (Arvicanthus niloticus). between August,
1987 and Nay, 1989. All samples were separately
subjected to the artificial enzymatic digestion
technique (using 1% acid pepsin). In addition,
carcasses were grossly examined for the presence of
cystic lesions. Records of striated muscle biopsies
done between 1975 and 1987 at Ahmadu Bello University
Teaching Hospital (ABUTH) Zaria, were also reviewed for
cases of Trichinella spiral is infection.
L- spiral is larvae were recorded in three (0.57.)
of the 620 pigs sampled. In all positive cases, larvae
were recovered only from the diaphragm and none from
the tongue. Less than one larva per gram of
musculature was recovered. Gross examination of swine
carcasses revealed Cysticercus eellulosae cysts in
13(2.1"/.) of the pigs. Such cysts were distributed in
various parts of the body including the tongue (23.17.),
thigh muscle (23.17.), masticatory muscle (23.17.),
diaphragm (15.47.) and heart (15.47.).a
All the tissues of the brown, field rats examined
were negative for T. spiralis larvae. Also records of
the human muscle biopsies reviewed did net reveal any
case of trichinosis being diagnosed. However, the
potential for human infections does exist.
