Abstract
Faecal samples from 168 goats belonging to eight urban establishments and representing three commonly encountered
management systems were screened for Campylobacter spp. Goats which were kept isolated from other farm animals with or
without good management systems were negative for Campylobacter spp., although in one of these units 2/9 chickens were
consistently positive for C. coli. However, 3 out of 20 goats confined in an enclosed area but in contact with C. coli positive pigs
(3/10) and chickens (2/8) were infected with C. coli. Furthermore, 24 milk samples tested on three different occasions were
negative. This study indicates that goats are not natural hosts of C. coli or C. jejuni and that pigs and poultry act as a source of
infection.

1. Introduction
Tanzania is estimated to have an indigenous goat
population of around 8 million and most are owned by
pastoralists (FAO, 1992). For the past two decades,
goats have become increasingly popular in urban and
semi-urban areas as a supply for protein requirements.
In addition, small ruminants provide a subsidiary
source of income and a safeguard against crop failures
and crop prices (Das and Sendalo, 1991; Seyoum,
1992). With growing human population and concom-
itant pressure on traditional grazing lands, small rumi-
nant production in urban and semi-urban areas is set to
increase. Tanzanian meat goats are hardy animals
requiring fewer resources (Anon, 1984; Wiktorsson,
1992). These goats are often kept in combination with

cattle, sheep, pigs and poultry, where veterinary inputs
are usually low or absent and hygiene poor. Con-
versely, milk goats are kept by governmental organi-
zations and privately owned progressive farms, where
hygiene is good and veterinary inputs satisfactory (Eik
et al., 1988). The presence of Campylobacterjejuni
among healthy and diseased farm animals has been
reported in many countries (Prescott and Bruin-Mosch,
1981; Olubumni and Adeniran, 1986). Jiwa and Ish-
engoma (1985) reported the presence of C.jejuni and
C. coli in a number of animals including goats on the
Sokoine University of Agriculture Farm, Morogoro,
Tanzania. The objectives were to study occurrences of
Campylobacter in urban goats and other domesticated
animals, and the question of which species serve as
natural host of the natural infection. Parts of this study
have been reported by Jiwa (1991).
