Abstract
A serological and parasitological survey of
toxoplasmosis was conducted on some food animals
(cattle sheep, goats and swine) in Kano and Kaduna
States of Nigeria to determine prevalence of T. gondii
infection.
A combination of Indirect Haemagglutination (IHA)
and Indirect Fluorescent Antibody (IFA) tests were the
serological methods used for cattle, goats and sheep
serum samples while the IHA and the Sabin-Feldman (SF)
dye tests were used for the swine serum samples.
Attempts were made to isolate T. gondii from
seropositive animals by the mouse inoculation technique,
A total of 762 animals were sampled comprising
200 each of cattle, goats, sheep and 162 swine. Serum
samples were collected prior to slaughter while
tissue samples of the same animals were collected after
slaughter at various abattoirs in these two States.
Results show that 3, 4,5, 9 and 6.8 per cent
respectively of cattle, goats, sheep and swine were
positive by the Indirect Haemagglutination te3t while
3, A, 9.5 per cent of cattle, goats and sheep were
positive by the Indirect Fluorescent Antibody Test and
8 per cent of swine by the Sabin-Feldman (SF) dye test.
There was no statistical significant difference
in the results based on age, sex, breed and
geographical location P<0.0.05(chi square). Attempt
to isolate Toxoplasma gondii from the tissues of the
serologically positive animals was unsuccessful.
It is concluded, based on the present study, that
meat of commonly slaughtered animals in Northern
Nigeria present minimal public health hazard as far as
T. gondii is concerned.
