Listeria monocytogenes
is of particular concern for pregnant women, the aged and the infirmed. It is recommended that these
2
concerned groups avoid handling this organism. Dispose of all reagents and other contaminated materials by acceptable procedures
3
for potentially biohazardous materials.
Some reagents in the kit contain 1 g/L concentrations of sodium azide. Check local
4
regulations prior to disposal. Disposal of these reagents into sinks with copper or lead plumbing should be followed immediately with
5
large quantities of water to prevent potential hazards.
This kit contains products of animal origin. Certified knowledge of the origin
6
and/or sanitary state of the animals does not totally guarantee the absence of transmissible pathogenic agents. It is therefore
7
recommended that these products be treated as potentially infectious and handled observing the usual safety precautions (do not ingest
8
or inhale)

Inclusivity Study
10
Methodology
11
The purpose of inclusivity testing is to ensure that the VIDAS LMX test can detect a representative range of serotypes of
Listeria
12
monocytogenes
. All cultures used for inclusivity testing were checked for purity prior to testing. Sixty
Listeria monocytogenes
strains
13
were enriched in LMX broth for 26h at 37°C and tested on the VIDAS LMX assay.
14
Results
15
The inclusivity results are presented in Table 1. All
Listera monocytogenes
strains tested were detected by the VIDAS LMX assay.
