Bombella apis
Description and Significance
Bombella apis is a gram-negative bacteria that is rod-shaped. It is a non-motile aerobic bacteria. Bombella apis can be found in the midgut of honey bees. [1]
Genome Structure
The genome size of Bombella apis is 2.01 Mb. This microbe has a GC content of 59.56%.
Bombella apis has a genome that is 2,086,308 bp long and contains 1,975 protein-coding genes. [7]
Cell Structure, Metabolism and Life Cycle
B. apis is an acetic acid bacteria, that does oxidative fermentation. It acquires nitrogen from ammonia, carbon from glucose, and energy from sugars and amino acids. B. apis has also been found to thrive in 30% glucose content. [9]
Their cells are non-motile, aerobic, and Gram-negative rods that are 1.0–2.5 µm in length and 0.5–0.6 µm wide.
Ecology and Pathogenesis
Habitat; symbiosis; biogeochemical significance; contributions to environment.
If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
Bombella apis has been sequenced and found to be closely associated with nectar, developing honey bee larvae, and honey bee queens. Bombella apis is found in well-defined niches within the bee community. It is very rare to find it outside these niches. These locations include the queen's gut microbiome, nurse hypo pharyngeal glands, nurse crops, food stores, royal jelly, and worker jelly. [3][4]
Bombella apis has been found to be able to protect themselves against phages. [3]
