Faecal specimens were collected from different animal species
(puppies, Guinea fowl, chicken and pigs) at different farm
locations in Lagos (Inner City - Central urban area;
peripheral City – rural/farming houses; Rural - a farming
and agricultural zone, where people raised their own
domestic animals). In all, 200 animals were sampled out of
which twenty (14%) were positive for Campylobacter,
seventeen (17) of these (60.7) were positive for animals
from peripheral zone, nine (9)(32.1%) were found positive
for animals from the rural zone and two (2)(7.1%) were
positive for animals obtained from the inner zone of Lagos
metropolis. The trend of infection by Campylobacter
as exemplified in this study was pig, two samples (7.1%);
chicken, 7 samples (25%); sheep, two samples (7.1%);
puppies, 0 (0.0%), and guinea fowl, 17 samples (60.7). The
peripheral zone had more incidence of Campylobacter
with an incidence rate in the order peripheral zone (8.5%»
rural zone (4.5%) > inner zone (1.0%). The results of
biochemical tests reveal that three (3) samples were
positive for Campylobacter coli biotype II, seventeen
(17) samples were positive for Campylobacter coli
biotype I and one (1) sample for Campylobacter jejuni
biotype I. These results are indicative that the epidemic of
Campylobacter infection is possible amongst handlers
of these farm animals.
