Listeria monocytogenes is a gram-positive, intracellular, food-borne pathogen capable of causing severe infections in immunocompromised or pregnant individuals, as well as numerous animal species. Genetic analysis of Listeria pathogenesis has identified several genes which are crucial for virulence. The transcription of most of these genes has been shown to be induced upon entry of Listeria int...

Listeria monocytogenes is worldwide a pathogen, but the geographic distribution of clones remains largely unknown. Genotyping of 300 isolates from the 5 continents and diverse sources showed the existence of few prevalent and globally distributed clones, some of which include previously described epidemic clones. Cosmopolitan distribution indicates the need for genotyping standardization.

We present here the whole-genome sequences of Listeria monocytogenes from Ganges River water, agricultural soil, and human clinical samples from Varanasi, India, which will be used for a comparative analysis.

Total number of 150 samples comprising of raw-vegetables and raw-meats were obtained from three different markets: Ose market, Ochanja market and Main-market all in Onitsha metropolis, Anambra State, Nigeria. These samples were analyzed bacteriologically for Listeria monocytogenes using a selective and differential media chromagar Listeria. Out of the total number of 150 samples studied, result...

Infection due to Listeria monocytogenes mostly effects immunocompromized hosts (1,2). Although, viruses usually cause encephalitis and bacterial infections are associated with meningeal inflammation, Listeria monocytogenes is one of the few bacterial microorganisms that may present as a meningoencephalitis and most frequently as a rhombencephalitis (1,2). Listeria rhombencephalitis causes respi...

Listeriosis in human is clinically characterized as perinatal listeriosis, neonatal listeriosis and adult listeriosis. Listeria spp are an established pathogen in animals, and human infections are usually seen following ingestion of contaminated food (processed food). Human infections of Listeria spp initially present with gastrointestinal symptoms. Meningitis, septicaemia, brain abscess and pr...

NMRI mice were experimentally infected with Listeria monocytogenes serotypes 1/2b, 3a, 4b, and 4d and Listeria innocua serotype 6b by different means. The course of infection was monitored, using bacteriological and histological methods. The following typical features of experimental infection with the various L. monocytogenes and L. innocua serotypes were observed. (i) On the basis of the mean...

Here, we report the draft genome sequences of three Listeria monocytogenes isolates from fresh leaves collected in Nigeria, belonging to sequence types ST5 and ST155 (sublineages SL5 and SL155, respectively).
