Species

Listeria ivanovii

Description and significance

L. ivanovii is a non-spore forming, gram-positive, rod shaped bacteria. L. ivanovii is pathogenic, mainly infecting small ruminants and cattle, causing septicemic diease. Human cases of disease caused by L. ivanovii are extremely rare (1).

Genome Structure

L. ivanovii contain one circular chromosome of 2,928,879 base pairs with 143 open reading frames and has an average G+C content of 37.1%. L. ivanovii contains six complete rRNA operons, 2,782 protein coding-genes, and 67 tRNA genes. The L. ivanovii genome contains 86 pseudogenes, of which 37 are truncated and 53 are interrupted by frameshift mutations (1).
