Infection traits and growth of "Candidatus Liberibacter asiaticus" inside microfluidic chambers

The bacterium ‘Candidatus Liberibacter asiaticus’ (LAS) is the suspected causal agent of the disease known as citrus greening (or huanglongbin), affecting citrus production worldwide, especially in Florida (US), Brazil, and China. Culturing LAS in the laboratory by traditional bacterial culture methods is extremely difficult. This has caused a knowledge deficit regarding LAS biology that inhibits the generation of well-informed ideas for pathogen control. We are starting a new project based on the use of a novel methodology which uses microfluidic chambers and microscopic observations to improve the culture conditions of LAS and confirm infection traits and nutritional requirements suggested by the recent full genome sequence.
