Thekey differencebetweenListeria monocytogenesandListeria sppis thatL. monocytogenesis a foodborne human pathogenic species of the genusListeriawhileListeriaspp is a member of theListeriagenus thatcontains 21 species, including pathogenicL. monocytogenesand non-pathogenicListeria innocua.
The genusListeriabelongs to the classBacilliand the orderBacillales.BacillusandStaphylococcusalso belong to the same class and order. This genus was named after Joseph Lister. This genus contains 21 species as of 2021. Some of them areL. monocytogenes, L. innocua, L. ivanovii, L. marthii, L. aquatica, L. booriae, L. cornellensis, L. costaricensis, L. goaensis, L. SeeligeriandL. thailandensis. This genus has both pathogenic and non-pathogenic species. For example,L. monocytogenesis a pathogenic bacterium that causes listeriosis. On the other hand,L. innocuais generally not infectious.

What isListeria Monocytogenes?
Listeria Monocytogenesis a foodborne human pathogenic species of genusListeria,which is gram-positive, rod-shaped, andfacultatively anaerobic. They cause an infection called listeriosis. Listeriosis is a bacterial infection that can cause severe illness, including sepsis, meningitis, or encephalitis. Sometimes, it results in lifelong harm and even death. Specifically, the elderly, newborns and immunocompromised are at a greater risk of this infection.L. monocytogenesis identified as a foodborne pathogen. It is responsible for an estimated 1,600 illnesses and 260 deaths in the United States, annually. It grows at lower temperatures as 00C, which increases the potential risk of infection.L. monocytogenescontain virulent factors such as listeriolysin, phospholipases, internalin, and ActA protein. Lisetriolysin and phospholipases help bacteria to escape from the phagocytotic vacuole. The internalin mediates the bacterial adhesion and invasion of epithelial cells in the human. ActA protein increases cell mobility intracellularly.
Listeriaselective agar media, DNA probes, orELISAare used to detect this organism in the pathogenic environment. Penicillin, ampicillin, and trimethoprim-sulfamethoxazole have been shown effective againstListeriainfection.
What isListeriaSpp?
Listeriais a genus of are gram-positive, rod-shaped, facultatively anaerobic, intracellular pathogens in mammals. Listeria spp is any member of this genus. This genus contains 21 species, including pathogenic and non-pathogenic bacteria.Listeriaspecies are mainly found in soil, water, vegetation, effluents, and a broad range of food.
The twenty-one species that include this genus areL. monocytogenes, L. newyorkensis, L. riparia, L. rocourtiae, L. seeligeri, L. thailandensis, L. valentina, L. weihenstephanensis,L. welshimeri,L. innocua, L. ivanovii, L. marthii,L. aquatica, L. booriae, L. cornellensis, L. costaricensis, L. goaensis, L. fleischmannii, L. floridensis, L. GrandensisandL. grayi. CertainListeria sppcause severe listeriosis. Some of them areL. monocytogenes,L. ivanoviiandL. grayi. From 2011 to 2019, these bacteria caused outbreaks in the US, Europe, South Africa and Spain.
氨苄青霉素等抗生素,青霉素,amoxicillin, erythromycin, trimethoprim-sulfamethoxazole, vancomycin, and fluoroquinolones can be used for treatment. Some species of this genus are non-pathogenic.L. Innocuais an example of non-pathogenicListeria. The common methods that are used in the laboratories to detectListeriaare culture-based methods, PCR tests and ELISA. Researchers are now experimenting with the possibility of usingListeriaas a cancer vaccine. This is because of its ability to induce potent innate and adaptive immunity.
What are the Similarities BetweenListeria MonocytogenesandListeria Spp?
- Both are gram-positive, rod-shaped, facultative anaerobes.
- Both are intracellular.
- They cause human infections.
- Both of them can be identified through selective culture media, PCR or ELISA tests-based methods.
What is the Difference BetweenListeria MonocytogenesandListeria Spp?
Listeriamonocytogenesare a foodborne human pathogenic species of the genusListeria.Listeria sppis a member of the genusListeriathat contains 21 species, including pathogenicL. monocytogenesand non-pathogenicListeria innocua.Thus, this is the key difference betweenListeria monocytogenesandListeriaspp. Moreover,L. monocytogenescan be mainly found in contaminated food. In contrast,Listeria speciesare mainly found in soil, water, vegetation, effluents, and a broad range of foods.
The below infographic lists the differences betweenListeria monocytogenesandListeriaspp in tabular form.
Summary –Listeria MonocytogenesvsListeria Spp
Listeria monocytogenesis a species of genusListeriathat causes the infection listeriosis in human.Listeria sppare gram-positive, rod-shaped, facultative anaerobic bacteria belonging to theListeriaceaefamily and composed of 21 species.They includeListeria monocytogenes,which is pathogenic for humans (foodborne illness) and rarely for animals like ruminants. They also have species likeListeria ivanovii这是动物致病性但很少哼ans, and species likeL. innocua,which is non-pathogenic. Thus, this is the summary of the difference betweenListeria monocytogenesandListeriaspp.
