Listeria Innocua

Listeria innocua is one of the six species included in the genus Listeria. Is mostly found in the environment (such as soil) and food resources. You can live in pH and temperature extremes and high salt concentrations. In terms of appearance, it is a rod-shaped Gram-positive bacteria. It is a spore-forming bacteria. Can a person live in a chain or other bacteria Listeria innocua. This is a mesophilic, operating at an optimum temperature of 30 to 37 degrees Celsius. Listeria innocua closely resembles that of family members, Listeria monocytogenes pathogenicity. Listeria innocua separately from meat through a technique called immunofluorescence, surface adherence. The meat samples inoculated with L. innocua and incubated at 30 ° C for 14-18 hours in the broth. The cells are separated from the flesh by the adhesion to the surface of polycarbonate membrane attached to glass microscope slides. After immunofluorescence microscopy was used to visualize the bacteria. Listeria innocua important because it is similar to foodborne L. monocytogenes pathogens, but non-pathogenic. This genome was sequenced to compare the genomes of L. monocytogenes pathogen to know why the past. Listeria Pregnancy

Listeria innocua is a circular chromosome of 3,011,209 base pairs with a G + C content of 37% Only the 2973 protein-coding genes in L. innocua, while the function can not be predicted 37% of the genes. Genome encodes a set of regulations, and the surface transport proteins. This explains why Listeria species can adapt and live in environments so different. Listeria innocua hatred found that less than 10 kb, a group of genes that lead to the pathogenicity of Listeria monocytogenes. This explains why L. innocua usually do not infect humans or animals. It also has a 81,905 base pair circular plasmid of unknown function.
