Salmonella belong to the Salmonella genus of Enterobacteriaceae. They cause two types of illness: food-borne gastroenteritis (salmonellosis), and typhoid/paratyphoid fevers.

PCT (Procalcitonin)

An early and specific host marker of a bacterial infection, PCT is useful to adapt antimicrobial prescription.

PCR (Polymerase Chain Reaction)

Molecular biology technology for in vitro amplification of genetic sequences, used to copy known DNA or RNA sequences in large quantities (by an order of magnitude of a billion) from an initially small quantity. This technology is particularly useful for detecting the presence of viruses.


A microbe which causes or has the potential to cause an infectious disease.

Molecular biology

Technique that can detect a bacterium, virus, yeast, parasite or a biomarker through the presence of DNA or RNA genetic sequences in a sample.


Study of microorganisms. bioMérieux uses culture-based microbiology methods for the growth of bacteria from biological fluids, food and pharmaceutical samples. The bacteria are subsequently identified and their susceptibility to antibiotics tested in certain cases.

MIC (Minimum Inhibitory Concentration)

A measure of the sensitivity of microbes to antibiotics or antifungals (antimicrobials). Organisms are tested for growth in various concentrations of antibiotic. This allows microbiologists to see which concentration (MIC) of antimicrobial will be effective against the pathogen.

MDRO (Multidrug-Resistant Organism)

MDROs are defined as microorganisms, predominantly bacteria, that are resistant to one or more classes of antimicrobial agents, complicating treatment of illnesses they cause. These highly resistant organisms deserve special attention in healthcare facilities in order to reduce the incidence of MDRO-related HAIs (healthcare-associated infections).

Mass spectrometry

Technique used to identify a molecule and determine its chemical structure by analyzing the mass and the charge of its ions.

In vitro diagnostics

Analysis of biological samples (urine, blood, etc.) performed outside the human body.
