This thesis aimed to investigate whether supplementation with specific bacteria would alter
the metabolic composition of honey bee (Apis mellifera) gut and bodily tissue and whether …

Animals interact with a diverse array of both beneficial and detrimental microorganisms. In
insects, these symbioses in many cases allow feeding on nutritionally unbalanced diets. It is …

The gut microbiota can have profound effects on hosts, but the study of these relationships in
humans is challenging. The specialized gut microbial community of honey bees is similar to …

Background Obligate bacterial symbionts alter the diets of host animals in numerous ways,
but the ecological roles of facultative bacterial residents that colonize insect guts remain …

Bacterial symbionts of eukaryotes often give up generalist lifestyles to specialize to particular
hosts. The eusocial honey bees and bumble bees harbor two such specialized gut …

Most bacterial species encompass strains with vastly different gene content. Strain diversity
in microbial communities is therefore considered to be of functional importance. Yet little is …

Diverse bacteria can colonize the animal gut using dietary nutrients or by engaging in
microbial crossfeeding interactions. Less is known about the role of host-derived nutrients in …

Numerous honeybee (Apis mellifera) products, such as honey, propolis, and bee venom, are
used in traditional medicine to prevent illness and promote healing. Therefore, this insect …

Not all bacterial gut symbionts are necessarily beneficial to the host. Some of them may be
neutral while others can even have detrimental effects. Determining the impact of individual …

Microbial consortia accompanied to all eukaryotes can be inherited from ancestors,
environment, and/or from various food source. Gut microbiota study is an emerging …
