Analytic company COPAN and Alverno Laboratories on Friday jointly announced that the successful results of the novel COLOREX Strep A chromogenic medium using Artificial Intelligence (AI) and digital detection to pre-assess Throat Strep Screens in WASPLab will be presented during the 2019 ASM Microbe in San Francisco on 23 June as a poster titled 'Digital Detection and the use of Artificial Intelligence to Detect Group A Streptococcus using a Chromogenic Agar'.
Factor VIII levels measured with the chromogenic substrate assay at the end of year three were mean and median of 32.7 IU/dL and 19.9 IU/dl, respectively, compared with mean and median of 36.4 IU/dL and 26.2 IU/dL, respectively, at the end of year two.
Segregation of chromogenic media for the detection of methicillin-resistant Staphylococcus aureus (MRSA);
Chromogenic media allow the presumptive identification of bacteria within 24 hours of incubation on the basis of clonal morphology and distinctive color patterns.
Each method has its own advantages and disadvantages over other conventional techniques like diffusion method are still available and routinely used.8 CHRO-Magar (CMRSA) is a selective and differential medium used for early detection of MRSA within 24 hrs from clinical specimens including nasal, peri-anal swabs and sputum.9 MRSA strains grow in the presence of antibiotic (cefoxitin) and after hydrolysis of chromogenic substrate produces blue colored colonies.
The ten pieces on display--largely photograms the artist made in the past two years using chromogenic materials--range from the small and delicate to the large and unwieldy, creating a series of encounters in which photography is experienced as the result of the artist's actions.
In general, the chromogenic medium is an alternative method to identify quickly the presence of pathogens or bacteria associated to sanitary problems.
