Listeria monocytogenes genome size

Monocytogenes Scott A GeneBank accession number AFGI000000001. Several others are currently being sequenced.

The main cause of listeriosis is consumption of food contaminated from sources in food processing environments.

Listeria monocytogenes genome size. Listeria monocytogenes is an opportunistic food-borne pathogen and the causative agent of listeriosis in animals and humans. We present the genome sequence of Listeria monocytogenes Scott A a widely distributed and frequently used serovar 4b clinical isolate from the 1983 listeriosis. Monocytogenes has a chromosome with a size of about 3 Mbp.

The EGD-e reference strain genome is of 2 944 528 bp with 39 GC Bécavin et al 2014. Monocytogenes is divided between 82 clonal complexes and 183 Sequence Types not related to. Listeria monocytogenes is a food-borne bacterial pathogen commonly associated with serious invasive infections of the central nervous system or of the developing fetus.

We present the genome sequence of Listeria monocytogenes 07PF0776 a serovar 4b isolate from a human myocardial abscess that exhibits enhanced invasion of cardiac tissue. Listeria monocytogenes is a gram positive foodborne pathogen that causes the severe infection listeriosis Buchanan et al 2017. Listeriosis infects an estimated 1600 people and causes about 260 deaths annually in the United States 1.

GC content 380 and genome size are in the range found typical for L. The genome of strain QOC1 is approx. 74 kbp larger than the QOC2 genome.

Monocytogenes Finland 1988 GeneBank accession number CP002004 and 302 Mb L. Monocytogenes Scott A GeneBank accession number AFGI000000001. In the future the ongoing efforts to finalize complete and draft genome sequences for 16 L.

Monocytogenes isolates representing serotypes 12a 12b 12c 4a 4b and 4c httpwwwbroadmiteduannotationgenomelisteria_groupMultiHomehtml which will not only represent these 6 serotypes but also the 4 main lineages within L. Monocytogenes ie lineages I II. A total of 2743 Listeria monocytogenes isolates collected as part of routine surveillance were characterized in parallel by PFGE and core genome multilocus sequence typing cgMLST extracted from WGS.

We investigated PFGE and cgMLST clusters containing human isolates. Listeria monocytogenes are usually psychrotrophic which means that they multiply even in the cold and can pose a risk to food at temperatures as low as around 2 - 4 C. This important point plays a decisive role in the calculation of the best-before date.

The ST87 pan and core genome contained 3687 genes and 2677 genes respectively. The ST87 core genome is 137 larger than the L. Monocytogenes core genome 2354 genes while the ST87 pan genome is 159 smaller than the species pan genome 4383 genes 23.

Listeria Monocytogeneshas two strains of sequences that have been sequenced. Several others are currently being sequenced. The size of these strains is 29 Mb and the percentage content ofGC is 37- 39.

Listeria monocytogenes is an important foodborne pathogen responsible for the disease listeriosis and can be found throughout the environment in many foods and in food processing facilities. The main cause of listeriosis is consumption of food contaminated from sources in food processing environments. Persistence in food processing facilities has previously been shown for the L.

The bacterial genus Listeria contains pathogenic and non-pathogenic species including the pathogens L. Ivanovii both of which carry homologous virulence gene clusters such as the prfA cluster and clusters of internalin genes. Initial evidence for multiple deletions of the prfA cluster during the evolution of Listeria indicates that this genus provides an interesting.

Listeria monocytogenes is an important foodborne pathogen that causes considerable morbidity in humans with high mortality rates. In this study we have sequenced the genomes and performed comparative genomics analyses on two strains LM115 and LM41 isolated from ready-to-eat food in Malaysia. The genome size of LM115 and LM41 was 2959041 and 2963111 bp respectively.

Monocytogenes is actively motile by means of peritrichous flagella at room temperature 2025 C the organism does not synthesize flagella at body temperatures 37 C. The genus Listeria belongs to the class Bacilli and the order Bacillales which also includes Bacillus and Staphylococcus.
