Campylobacter jejuni as a Primary Colonizing Biofilm Former

Abstract :

Campylobacter jejuni can be difficult in the environment and extremely fragile, therefore carry-over
between flocks has been difficult to explain. The aim of the study was to determine if the survival of C. jejuni
outside the host could be due to a capability to form biofilms. In these experiments, C. jejuni was cultured
under conditions of starvation, temperature variations, different cell concentrations, after passage through
a chick gastrointestinal tract or with a conditioning film. However, no evidence of attachment and biofilm
formation was found outside of growth conditions. Since growth conditions usually do not occur outside the
host, it may be concluded that C. jejuni is most likely not a primary biofilm colonizer outside the host. These
studies indicate that C. jejuni may utilize a strategy other than primary biofilm formation to survive outside
the host.
