Nonobese diabetic (NOD) mice spontaneously develop diabetes as a consequence of an autoimmune process that can be inhibited by immunotherapy with the 60-kDa heat shock protein (hsp60), with its mycobacterial counterpart 65-kDa (hsp65), or with other Ags such as insulin and glutamic acid decarboxylase (GAD). Microbial infection and innate signaling via LPS or CpG motifs can also inhibit the spon...

We report a case of disseminated Mycobacterium genavense infection resulting from neutralizing anti-interferon-γ autoantibodies in the patient. We identified M. genavense targeting the hsp65 gene in an aspiration specimen of the lymph node. Adult-onset immunodeficiency caused by neutralizing anti-interferon-γ autoantibodies, in addition to HIV infection, can lead to disseminated nontuberculous ...

Mycobacterium massiliense, an emerging pathogen that is increasingly reported as a causative agent in infections occurring during medical procedures, is difficult to be identified using conventional methods. Here we report the case of a cutaneous M. massiliense infection that was associated with repeated surgical procedures and that was identified via a comparative sequence analysis of rpoB and...

We herein present the third set of documented clinical Mycobacterium setense cases. Three clinically unrelated isolates were identified and characterized using various key conventional and molecular diagnostic tests. Phenotypic and molecular data analysis, particularly 16S rDNA, hsp65, and rpoB sequencing, provided evidence of M. setense involvement in clinical infections in Iranian patients. O...

We determined nucleotide sequences of rpoB, hsp65, and sodA in 59 clinical isolates (from 58 patients) of the Mycobacterium abscessus group. Identification to the species level, based on three target genes, was concordant for 44 isolates (25 M. abscessus, 13 Mycobacterium massiliense, and 6 Mycobacterium bolletii isolates) and discordant for 15 isolates which had "interspecific composite patter...

Atherosclerosis bears many similarities to inflammatory/autoimmune diseases like rheumatoid arthritis and multiple sclerosis (MS).1,2 Compelling data from experimental models show that such diseases may be treated by vaccination. Will it be possible to attack atherosclerotic cardiovascular disease with the same approach? Several studies have shown positive effects of immunization with antigenic...
