Progress in the study of the immune response to pathogens and candidate vaccines has been impeded by limitations in the methods to study the functional activity of T-cell subsets proliferating in response to antigens processed and presented by antige

Koch's postulates are regularly included in the lecture portion of microbiology courses, but rarely are they demonstrated in a microbiology teaching lab. This is understandable given the logistical challenges of undergraduates working with pathogenic

Several fast- to intermediate-growing, acid-fast, scotochromogenic bacteria were isolated from Sarracenia purpurea pitcher waters in Minnesota sphagnum peat bogs. Two strains (DL734T and DL739T) were among these isolates. On the basis of 16S rRNA gen

A fast-growing, non-chromogenic, acid-fast-staining bacterium (DL90T) was isolated from a peat bog in northern Minnesota. On the basis of 16S rRNA gene sequence similarity (99.8 % identity with Mycolicibacterium septicum and 98 % with Mycolicibacteri

Environmental mycobacteria are capable of forming biofilms in low-nutrient environments, and these biofilms may act as reservoirs for opportunistic infections. The purpose of this study was to determine if bacteriophages could disrupt existing biofil

Bacterial sporulation in Gram-positive bacteria results in s mall a cid- s oluble p roteins called SASPs that bind to DNA and prevent the damaging effects of UV radiation. Orthologs of Bacillus subtilis genes encoding SASPs can be found in many sporu

The stringent response of Mycobacterium tuberculosis is coordinated by Rel and is required for full virulence in animal models. A serological-based approach identified Wag31Mtb as a protein that is upregulated in M. tuberculosis in a rel-dependent ma

Adaptation to environmental stress is an important survival characteristic of any bacterial species. As a soil-dwelling saprophyte, Mycobacterium smegmatis is exposed to factors such as UV light and rounds of freezing and thawing that occur in temper

Mycobacterial species are characterized by the presence of lipid-rich, hydrophobic cell envelopes. These cell envelopes contribute to properties such as roughness of colonies, aggregation of cells in liquid culture without detergent, and biofilm form

Mycobacterium avium subsp. paratuberculosis is the causative pathogen of Johne's disease, a chronic inflammatory wasting disease in ruminants. This disease has been difficult to control because of the lack of an effective vaccine. To address this nee
