Bacterial fruit blotch (BFB) affects cucurbit plants around the world and can be a serious threat to farmers because it spreads through contaminated seed. BFB is the result of an infection by Gram-negative Acidovorax citrulli bacteria, which has only been recently studied in detail. Members of A. citrulli are Gram-negative rod shaped bacteria with the dimensions 0.5× 1.7 μm. They move via polar flagella. No known reliable sources of BFB resistance exist today, so seed hygiene and thorough testing of breeding facilities are the best way to control spreading. No known control methods, however, are extremely reliable for reducing BFB infection.
