Lis·te·ri·a mon·o·cy·to·g'enes

a bacterial species causing meningitis, encephalitis, septicemia, endocarditis, abortion, abscesses, and local purulent lesions; often fatal; found in healthy ferrets, insects, and the feces of chinchillas, ruminants, and humans, as well as in sewage, decaying vegetation, silage, soil, and fertilizer. Sometimes involved in infections in immunocompromised hosts. A causative agent of perinatal infections, neonatal sepsis, and septicemia; also recently linked to food-borne diseases; especially associated with meat and dairy products.

Listeria monocytogenes

The causative agent of listeriosis. This species lives in soil or the intestines of animals and may contaminate food, esp. milk or meat. Its growth is not inhibited by refrigeration.

We analyzed 543 environmental L. monocytogenes isolates of molecular serotype IIa (comprising the conventional serotypes 1/2a and 3a) that corresponded with the spatial and temporal distribution of cases in southern Germany.
L. monocytogenes strains NCCP10805, NCCP10808, NCCP10809, NCCP10810, and NCCP10943, which were isolated from meats and human (Table 1), were cultured in 10 mL nutrient broth plus 0.6% yeast extract (NBYE; Beckton, Dickinson, and Company, Sparks, MD, USA) at 30[degrees]C for 24 h.
Animal contamination can occur by consumption of water, pasture or silage and the presence of L. monocytogenes in fecal excretion was not necessarily related to the occurrence of listeriosis (CZUPRYNSKI, 2005; ESTEBAN et al., 2009).
The prevalence and molecular characteristics of Listeria monocytogenes are generally unknown in Nigeria and thus this present study was carried out with the aim of characterizing L. monocytogenes isolates from raw milk and milk products using PCR and to determine the virulence and the phylogenetic characteristics of the isolates.
In conjunction, the approval covers the use of the ANSR system to detect L. monocytogenes in hot dogs, Mexican-style cheese, cantaloupe, guacamole, pasteurized liquid egg, sprout irrigation water and sponge samples from stainless steel surfaces, concluded the company.
