Description and Significance
Chryseobacterium Nemaophagum is rod-shaped. The golden color on it was shown due to the production of a flexirubin- type pigment. It first isolated from Caenorhabditis briggsae nematodes in rotting apples in France. It has gliding motility. They are pathogens of nematodes. They represent a control agent for important nematode parasites.
Genome Structure
Chryseobacterium Nematophagum is a bacillus that is oxidase-positive,gram-negative rods that exhibit gelatinase activity. The genomes of JUb129 and JUb275 were predicted to encode 3738 and 3586 protein sequences. Grows optimally at 30 degrees Celsius on an agar plus 5% sheep's blood or a tryptone soy agar plus 5% sheep's blood.
Cell Structure, Metabolism and Life Cycle
Chryseobacterium nematophagous kills the environmental stages of a wide range of nematode parasites. After ingested by a nematode they attack it from the inside by breaking down its extracellular matrics and then kill it.
Ecology and Pathogenesis
This bacteria is mainly found in soil, water, and various environmental sources. But specifically more known for their interactions with nematodes. They effectively kill C. elegans (nematodes) in all different stages, leading to significant mortality. C.elegans are attracted to and eat these bacteria and within the first three hours of being digested, the bacilli degrade the anterior pharyngeal chitinous ling and enter the body cavity and then kill the host. These bacteria also infect and kill bacterivorous free-living stages of all parasitic nematodes.
