Klebsiella variicola At-22

Names Klebsiella variicola At-22
Accession numbers NC_013850
Background Bacteria of the genus Klebsiella are widely distributed in nature, in the soil and in water. They are also part of the normal flora of the human intestinal tract, but usually in low numbers compared with E. coli. Klebsiella variicola is a recently (2004) described species distributed both in plants and in clinical settings, representing less than 10% of the clinical Klebsiella isolates previously considered as K. pneumoniae.Amazonian leaf-cutter ants cut leaves and bring them to a fungal garden, which they use as a substrate to cultivate a fungus (family Lepiotaceae) for food. Additionally these ants engage in another association with Actinobacteria (genus Pseudonocardia), which produce antibiotics to help defend the fungus garden from parasites. It has now been discovered that N(2) fixation occurs in leaf-cutter ant fungus gardens and indicated the presence of N(2)-fixing bacteria within the garden matrix. It is estimated that a single mature leaf-cutter ant colony may contribute as much as 1.8 kg of fixed N per year into neotropical ecosystems (adapted from PMID 19965433). (HAMAP: KLEVT)
