Multiple cytokines are released when blood from patients with tuberculosis is stimulated with Mycobacterium tuberculosis antigens.

Background: Mycobacterium tuberculosis (Mtb) infection may cause overt disease or remain latent. Interferon gamma release assays (IGRAs) detect Mtb infection, both latent infection and infection manifesting as overt disease, by measuring whole-blood interferon gamma (IFN-γ) responses to Mtb antigens such as early secreted antigenic target-6 (ESAT-6), culture filtrate protein 10 (CFP-10), and TB7.7.

Development of a MLST-biased SNP microarray for Candida albicans.

We have developed a single nucleotide polymorphism (SNP) detection microarray for the human pathogenic yeast, Candida albicans, consisting of synthetic oligonucleotides bound to microscope slides. The array consists of multiple replicates of 79 SNPs, derived from 19 discrete loci located on all eight chromosomes. These loci include seven genes consisting of 57 SNPs that comprise a multi-locus sequence typing (MLST) consensus scheme for the species.
