RPMI Agar (RPMI1640, MOPS, L-glutamine, 2% Glucose) is intended for the AFST (antifungal susceptibility testing) and is recommended for usage with Antifungal MTS™ (MIC Test Strip).
Learn more about MTS™ for yeasts
Learn more about MTS™ for moulds
Pick 4-5 colonies from 24-hours old cultures and suspend in saline solution or sterile water in order to obtain a 0.5 McFarland cell density. Introduce a sterile swab into the suspension and inoculate the RPMI Agar plate. Allow the plate to dry, position the antifungal strip onto the agar surface with the maximum concentration nearest the periphery of the plate.
Incubate at 35 °C for 24-48 hours.
Read the M.I.C. value where the edge of the inhibition ellipse intersects the strip (intersection between two scale segments should be round up to the higher value).

EnteroPluri-Test is a 12-sector system containing special culture media for the identification of Enterobacteriaceae and other Gram-negative, oxidase negative bacteria. The system allows the simultaneous inoculation of all media present in the sectors and 15 biochemical reactions. The microorganism is identified by evaluating the color change of each culture medium after 18-24 hours of incubation at 36±1°C and by a code number obtained from the biochemical reaction interpretation.

Liofilchem confirms its continuous dedication to meet the pharmaceutical and cosmetics microbiology needs with the introduction of TAT Broth, a ready-to-use liquid medium for the microbiological examination of cosmetics and topical drugs, particularly from highly viscous or gelatinous materials. This medium, also known as Fluid Casein Digest – Soy Lecithin – Polysorbate 20 Medium (SCDLP 20 Broth), complies with ISO 21149 for detection of aerobic mesophilic bacteria.
Liofilchem also produces Eugon LT SUP, a highly nutritious medium used for the detection and enumeration of microorganisms in cosmetic products and TSB + Capitol 4, particularly suitable for testing viscous samples.

new Chromatic Super CAZ/AVI
Chromogenic medium for the detection of Ceftazidime-avibactam resistant Gram-negative bacteria

Chromatic Super CAZ/AVI is a selective and differential chromogenic medium used for screening ceftazidime-avibactam resistance in Enterobacterales and Pseudomonas aeruginosa.
Results can be interpreted after incubation for 18-24 hours. Subculture to a non-selective medium is required for confirming identification, antimicrobial susceptibility testing and epidemiological typing.

VTM
Transport medium for Viruses, Chlamydia, Mycoplasma and Ureaplasma
VTM is suitable for collection and preservation of clinical specimens containing viruses, including SARS-CoV-2 (COVID-19), Chlamydia spp., Mycoplasma spp. and Ureaplasma spp. The transport medium can be used with swabs and aspirates and is available in a plastic, screw cap tube (or a bulk format, 200 mL glass bottle). The transported microorganism remains viable for 48 hours at room or refrigerated temperature. VTM does not contain guanidium thiocyanate.
Features:
• 10-25°C storage temperature.
• 1 year shelf life.
• Contains antimicrobial agents to minimize bacterial and fungal contamination, without affecting viruses, Chlamydia, Mycoplasma or Ureaplasma.
• A pH indicator (red phenol) indicates the medium integrity during the shelf life of the product.
• The tube stands upright on the laboratory bench thanks to the skirted, flat-bottom, while the conical shape allows an appropriate centrifugation of the sample.
• 16x100mm skirted tube with plastic red cap. Sterile. 100/pack

AF Genital System
A.F. Genital System (ref. 74156) is a 24-well panel containing biochemical substrata and antimicrobial drugs for detection, presumptive identification and susceptibility testing of microorganisms directly from urogenital specimens (vaginal swab, urethral swab, seminal fluid, urine).
The new improved configuration allows to separately identify and enumerate Ureaplasma spp. and Mycoplasma hominis.
Count of Ureaplasma spp.(Uu) 10e3 to ? 10e5 CFU/mL
Count of Mycoplasma hominis (Mh) 10e4 to ? 10e5 CFU/mL

Escherichia coli
Proteus spp. / Providencia spp.
Pseudomonas spp.
Gardnerella vaginalis
Staphylococcus aureus
Enterococcus faecalis
Neisseria gonorrhoeae
Streptococcus agalactiae (Group B)
Candida spp.
Just like all the Liofilchem direct microbial ID systems, the AF Genital System has the great benefits of:
- performing simultaneous microbiological screening of several microorganisms in one compact panel.
- reducing costs in man hours and laboratory consumables.
- easy to use and no equipments required.

Isavuconazole MTS™ (MIC Test Strip), IVU 0.002-32 ?g/mL , is a quantitative method for the in-vitro susceptibility testing of Candida spp., Aspergillus spp. and Mucorales.
Isavuconazole is a novel broad-spectrum triazole agent with activity against a variety of opportunistic and pathogenic yeasts and moulds. Isavuconazole can be administered either orally or intravenously as a water soluble prodrug, isavuconazonium sulfate (Cresemba®), which then is rapidly cleaved by esterases into active component and an inactive prodrug cleavage product. Isavuconazole inhibits ergosterol synthesis in the fungal membrane. Previous in vitro studies have shown good activity against all Candida spp and species of Aspergillus and Mucorales. Potent activity against Cryptococcus spp and other emerging yeast infections has been demonstrated as well.

D-value verification
Liofilchem®
D-value verification
Liofilchem performs D-Value and Z-Value analysis by direct inoculation of product or equipment using Biological Indicator Organisms (BI’s).

D-values are stated by the manufacturer on the Biological indicator but often require verification for a higher degree of accuracy and process specificity. The Pharmacopoeias and ISO11138 stress on the importance of D-value verification to ensure the accuracy of a stated manufacturer D-value.
Our Biological Indicator Evaluation Resistometer (BIER) Vessel autoclave verifies the D-value by accurately delivering a calibrated and pre-determined level of lethality.
The log reduction achieved for exposure time is assessed through the exposure of the BI for defined time points and interpretation via fractional analysis. This process allows the accurate verification of the manufacturer’s stated D-value.

Liofilchem®
Microbiology products

Cefiderocol MTS™ (MIC Test Strip), FDC 0.016-256 ?g/mL , is a quantitative method for the in-vitro susceptibility testing of Pseudomonas aeruginosa to Cefiderocol.
MTS™ consists of special porous paper impregnated with a pre-defined concentration gradient of an antimicrobial agent, used to determine the minimum inhibitory concentration (MIC) in ?g/mL of antimicrobial agents against bacteria as tested on agar media using overnight incubation and manual reading procedures.
Cefiderocol is a siderophore cephalosporin with activity against aerobic Gram-negative organisms. It binds to free iron and is actively transported into bacterial cells through the outer membrane. This Trojan horse strategy allows cefiderocol to enter the space in-between the bacterial cell walls and disrupt cell wall synthesis. In addition, cefiderocol is stable against nearly all beta-lactamases, including both the serine and metallo-carbapenemases.

Hamilton, MolGen, and EWC Diagnostics join forces to scale up SARS-CoV-2 testing capacity in the Netherlands
Today, Hamilton, MolGen, and EWC Diagnostics announce their strategic partnership to scale up SARS-CoV-2 testing capacity in the Netherlands.
Since the outbreak of the COVID-19 pandemic in Europe, demand for SARS-CoV-2 detection tests has significantly increased. In order to increase testing capacity, the Dutch government, through the Ministry of Health, Welfare and Sport, invited commercial organizations to respond to a tender released this summer.
PathoFinder and EWC Diagnostics partnership to meet COVID-19 testing demands in the Netherlands.
PathoFinder and EWC Diagnostics announce their collaboration to rapidly advance the expansion of COVID-19 testing capacity in the Netherlands by providing the Dutch government with complete sets of sampling materials and SARS-CoV-2 PCR kits.
