Abstract
ABSTRACT
Autoinducer molecules are utilized by gram-negative and gram-positive bacteria to regulate density-dependent gene expression by a mechanism known as quorum sensing. PCR and DNA sequencing results showed that
Campylobacter jejuni
and
Campylobacter coli
possessed
luxS
, which is responsible for autoinducer-2 (AI-2) production. Using a
Vibrio harveyi
luminescence assay, the production of AI-2 was observed in milk, chicken broth, and brucella broth by
C. coli
,
C. jejuni
,
Salmonella enterica
serovar Typhimurium, and
Escherichia coli
O157:H7 under different conditions.
