Carbapenemase-Producing Enterobacteriaceae (CPE)

Coris BioConcept
 has always been committed to developing new technologies and products so its customers can perform more rapidly and accurately the detection and identification of infectious agents.

To face the growing problem of antibiotic-resistant bacteria, we have developed a new family of tests under the brand name “RESIST”.


Carbapenemase-Producing Enterobacteriaceae (CPE) represent a major health concern and any diagnostic tool allowing to help their laboratory detection can improve patient’s safety. Until today, non-molecular confirmatory testings of the presence of carbapenemases of Class A (KPC) and B (VIM, IMP, NDM) have been available.

Coris has launched the OXA-48 K-SeT, the first rapid test for the detection of the OXA-48 family carbapenemase.


RESIST Range will be progressively available.

Resist Range - Carbapenemase Producing Enterobacteriaceae


This first worldwide unique rapid test, named OXA-48 K-SeT, is aimed at the detection in 15 minutes of OXA-48-like-producing Enterobacteriacae from culture colonies.
Coris BioConcept also launched the KPC K-SeT kit whose aim is the identification of Carbapenemase KPC in bacteria culture.

Launch of new respiratory products

Coris BioConcept is proud and pleased to announce the launch of three new respiratory products!

Streptococcus group A

Beta-hemolytic group A Streptococcus is one of the main bacteria responsible for upper respiratory tract infections, including sore throats, pharyngitis and scarlet fever.
Early diagnosis and antibiotic treatment of infections with group A Streptococcus help to drastically reduce the severity of symptoms and the incidence of serious complications including acute glomerulonephritis, rheumatic fever and peritonsillar abscess.

The Strep A-Strip test detects the specific antigen of group A streptococci directly from throat swab specimens.

Or visit the Streptococcus group A page.


Legionella pneumophila

Legionnaires’ disease is a serious pneumonia mostly (90%) caused by Legionella pneumophila which includes several serotypes with serogroup 1 accounting for over 80% of all infections.
The Legionella K-SeT is a direct antigen test to detect the Legionella pneumophila serogroup 1 antigen in urine samples.

The sensitivity and specificity are 97.6% and 100% which makes this test a prompt and suitable diagnostic tool in legionellosis diagnosis.

Contact us for more scientific or technical information regarding this product.

Or visit the Legionella pneumophila page.


Influenza A & B viruses

Rapid and reliable diagnosis of influenza is essential for identification of contagious patients and effective patient management.

The Coris “Influ A+B K-SeT” shows high sensitivity (90.9% type A and 91.8% type B) and specificity (100% type A et 98.1% type B).
The use of this test for diagnosis of influenza disease should enhance patient health care by enabling rapid and appropriate use of antiviral treatments and lowering inappropriate use of preventive antibiotic treatment still often prescribed by mistake.

HAT test to detect sleeping sickness – Market authorization in DRC !

Sensitivity and specificity of HAT Sero-K-SeT, a rapid diagnostic test for serodiagnosis of sleeping sickness caused by Trypanosoma brucei gambiense: a case-control study



Human African trypanosomiasis (HAT) is a life-threatening infection affecting rural populations in sub-Saharan Africa.

Large-scale population screening by antibody detection with the Card Agglutination Test for Trypanosomiasis (CATT)/Trypanosoma brucei (T b) gambiense helped reduce the number of reported cases of gambiense HAT to fewer than 10 000 in 2011.

Because low case numbers lead to decreased cost-effectiveness of such active screening, we aimed to assess diagnostic accuracy of a rapid serodiagnostic test (HAT Sero-K-SeT) applicable in primary health-care centres.

New Product : GastroVir K-SeT

This GastroVir K-SeT kit was developped for simultaneuous detection of two major viruses responsible for 50 to 70% of gastroenterological diseases: Rotavirus and Adenovirus – serotypes 40/41.

The detection requires a 15 minutes run time with only a few seconds of manual handling to collect the sample with the material provided in the kit.

Besides, a multi-centre validation has been performed on 1.201 sample and let to great results: the performances of the GastroVir K-SeT kit are similar to those of the strip format with a high sensitivity (>99%) and specificity (>99%).

NEW PRODUCT ! HAT – Rapid Detection Test for Sleeping Sickness

Human African trypanosomiasis

Human African trypanosomiasis (HAT), or sleeping sickness, is a life-threatening neglected tropical infection affecting rural populations in sub-Saharan Africa. In West and Central Africa, chronic trypanosomiasis is caused by Trypanosoma brucei gambiense infection.(1) Control of the disease has been facilitated by the use of the card agglutination test for trypanosomiasis, which is particularly suited for large-scale screening of the populations at risk.(2) With the steadily decreasing prevalence of trypanosomiasis, individual rapid diagnostic tests that can be used in primary health centers, that are stable at ambient temperatures, and that are highly specific have become a research priority.(1)

We developed two rapid diagnostic tests for trypanosomiasis caused by T. brucei gambienseinfection. The HAT Sero-Strip and HAT Sero-K-SeT tests detect trypanosome-specific antibodies and are, respectively, a dipstick and a lateral-flow device for testing blood (30 μl) or plasma (15 μl); both tests provide results in 15 minutes. The tests contain variant surface glycoproteins of the T. brucei gambiense variable antigen types LiTat 1.3 and LiTat 1.5.(3)

Evaluation of the test

The tests were evaluated with the use of plasma from 198 patients with trypanosomiasis that was confirmed on parasitologic analysis and from 99 local controls with neither clinical nor serologic evidence of the disease. The specimens were collected in the Democratic Republic of Congo (4) and obtained from the World Health Organization HAT Specimen Bank ( All specimens were tested with the use of immune trypanolysis, the reference test for detecting specific antibodies against T. brucei gambiense variable antigen types LiTat 1.3 and LiTat 1.5.(5) To evaluate the applicability of these tests when blood was used, samples of reconstituted blood were prepared by adding plasma from patients with trypanosomiasis or from local controls to sedimented blood cells from a healthy donor.

Results are summarized in Table 1. As compared with the immune trypanolysis test, the HAT Sero-Strip showed excellent sensitivity, with specificity being slightly lower when plasma was tested (P=0.05). When reconstituted blood was tested, the sensitivity and specificity of the HAT Sero-Strip did not differ significantly from the sensitivity and specificity of immune trypanolysis (P>0.05 for both comparisons); for the HAT Sero-K-SeT, the sensitivity was lower than that of immune trypanolysis (P=0.01), but the specificity was not significantly different (P=0.32).

If further evaluation in the field confirms their diagnostic accuracy, we believe that the HAT Sero-K-SeT and the HAT Sero-Strip, with an estimated price of less than $2.50 each, may become valuable tools in the control of trypanosomiasis.

Launch of our new product : Clostridium difficile

Clostridium difficile is one of the most prevalent nosocomial pathogen mainly affecting patients after antibiotic treatment. Toxinogenic strains of C. difficile cause infections from mild diarrhoea to pseudomembranous colitis, potentially leading to death. The tissue-damaging enterotoxin (Toxin A) and the cytotoxin (Toxin B) produced by toxinogenic strains of C.difficile are responsible for the disease.

Due to the lack of sensitivity of toxins A&B rapid diagnostic tests, recommended algorithms for testing for toxinogenic C. difficile infection require detection of the C. difficile GDH as antigenic marker in stool as a first step. This test should have the highest possible sensitivity to ensure that no infected patients are missed.

Coris BioConcept Clostridium K-SeT allows the specific detection of C.difficile‘s GDH in stool specimen. There is a 100% concordance for detection of GDH between the Clostridium K-SeT test and an ELISA assay.  Moreover, another study shows a 100% NPV regarding culture.  This evaluation has been conducted in a reference lab in Brussels and compared to a test regarded as the reference test in the EC and the US.

This study has shown that the Coris test performs better than the reference one. Results have been submitted at the ICAAC meeting in San Francisco this year.
