Arcobacter butzleri strains from poultry abattoir effluent in Nigeria [corrected].
OBJECTIVE
To investigate the prevalence, species distribution and genetic diversity of zoonotic Arcobacter species.


METHODS
Prospective study.


METHODS
Drainage system of a cosmopolitan chicken abattoir in Lagos, Nigeria.


METHODS
One hundred and fifty drainage water samples were enriched in a minimal antibiotics-containing medium at room temperature and bacteria then isolated by use of a membrane filtration method.


RESULTS
Twenty six (14%) of samples were positive for Arcobacter spp. Of these, 20 were examined by a comprehensive probabilistic identification scheme for Epsilobacteria and all strains identified as A. butzleri. AFLP analysis of these strains revealed considerable genetic diversity among the strains, with 12 genotypes defined at the 90% similarity level.


CONCLUSIONS
The prevalence of A. butzleri in Nigerian poultry abattoir effluent indicates this species may constitute a public health problem in this country. AFLP profiling could be a useful tool for molecular epidemiological and population genetic studies of this organism. This is the first known report of A. butzleri in Nigeria, and first application of AFLP analysis for genotyping the species.
