Lineage: Macrococcus caseolyticus; Macrococcus; Staphylococcaceae; Bacillales; Firmicutes; Bacteria
General Information: This methicillin-resistant strain was isolated from animal meat in a supermarket. This organism is a large gram positive coccus, related to the Staphylococcus, often associated meat and sheep, goat and cattle milk.
Subject: NC_003210:1904152 Listeria monocytogenes EGD-e, complete genome
Lineage: Listeria monocytogenes; Listeria; Listeriaceae; Bacillales; Firmicutes; Bacteria
General Information: This strain has numerous pathogenicity islands and genes as compared to the related non-pathogenic organism Listeria innocua. This organism, which causes listeriosis, is one of the leading causes of death from food-borne pathogens especially in pregnant women, newborns, the elderly, and immunocompromised individuals. It is found in environments such as decaying vegetable matter, sewage, water, and soil, and it can survive extremes of both temperatures (1-45 degrees C) and salt concentration marking it as an extremely dangerous food-born pathogen, especially on food that is not reheated. This organism is enteroinvasive, and utilizes an actin-based motility system by using a surface protein, ActA, that promotes actin polymerization, to spread intercellularly using the polymerized cytoskeletal protein as a "motor". There are 13 serovars associated with Listeria monocytogenes, and the serovar 4b strains are more commonly associated with invasive disease.
