Molecular methods have revealed that symbiotic systems involving bacteria are
mostly based on whole bacterial communities. Bacterial diversity in hoopoe
uropygial gland secretion is known to be mainly composed of certain strains of
enterococci, but this conclusion is based solely on culture-dependent techniques.
This study, by using culture-independent techniques (based on the 16S rDNA and
the ribosomal intergenic spacer region) shows that the bacterial community in the
uropygial gland secretion is more complex than previously thought and its
composition is affected by the living conditions of the bird. Besides the known
enterococci, the uropygial gland hosts other facultative anaerobic species and
several obligated anaerobic species (mostly clostridia). The bacterial assemblage
of this community was largely invariable among study individuals, although
differences were detected between captive and wild female hoopoes, with some
strains showing significantly higher prevalence in wild birds. These results
alter previous views on the hoopoe-bacteria symbiosis and open a new window to
further explore this system, delving into the possible sources of symbiotic
bacteria (e.g. nest environments, digestive tract, winter quarters) or the
possible functions of different bacterial groups in different contexts of
parasitism or predation of their hoopoe host.
