What is the common name for Listeria monocytogenes?
Listeriosis
Listeriosis is a serious infection usually caused by eating food contaminated with the bacterium Listeria monocytogenes. An estimated 1,600 people get listeriosis each year, and about 260 die.
Is Listeria DNA or RNA?

Why is it called Listeria monocytogenes?
Listeria monocytogenes is a Gram-positive bacterium, in the division Firmicutes, named after Joseph Lister. Its ability to grow at temperatures as low as 0 °C permits multiplication at typical refrigeration temperatures, greatly increasing its ability to evade control in human foodstuffs.
What is the difference between Listeria spp and Listeria monocytogenes?
The key difference between Listeria monocytogenes and Listeria spp is that L. monocytogenes is a foodborne human pathogenic species of the genus Listeria while Listeria spp is a member of the Listeria genus that contains 21 species, including pathogenic L. monocytogenes and non-pathogenic Listeria innocua.
Who discovered Listeria monocytogenes?
The official discovery of Listeria microorganisms dates back to 1924, when E. G. D. Murray, R. A. Webb, and M. B. R. Swann isolated L. monocytogenes as the etiological agent of a septicemic disease affecting rabbits and guinea pigs in their laboratory at Cambridge in England (458).
What is Listeria Wikipedia?
Listeria is a genus of bacteria with about ten species. It is named after Joseph Lister. Listeria are very common, they occur almost everywhere. Two of the ten species are pathogens: they can cause a disease called listeriosis in decaying food.
What is special about Listeria monocytogenes?
Listeria monocytogenes is a ubiquitous microorganism responsible for listeriosis, a rare but severe disease in humans, who can become infected by ingesting contaminated food products, namely dairy, meat, fish, and vegetables.
How would you isolate and identify Listeria monocytogenes?
Identification of the L. monocytogenes was done according to the standard microbiological tests such as catalase, oxidase, β haemolysis, motility test at 25°C, the CAMP assay, and acid production from xylose and rhamnose (17).
What is the genus and species of Listeria monocytogenes?
ListeriaListeria monocytogenes / Genus
What shape is Listeria monocytogenes?
The genus Listeria includes different species of ubiquitary present gram-positive rod shaped bacteria. The species Listeria monocytogenes causes severe diseases like meningitis and meningoencephalitis in humans.
Which part of the name Listeria monocytogenes is the genus name?
How do you confirm Listeria?
A blood test is often the most effective way to determine whether you have a listeria infection. In some cases, samples of urine or spinal fluid will be tested as well.
What color is Listeria monocytogenes?
ivanovii appear blue, surrounded by a yellow halo (xylose-positive) whilst the colonies of L. monocytogenes are blue without the halo (xylose-negative) (Fig. 3). The colonies of other Listeria spp.
