adult SLE patients was noted between the presence or levels of antibodies to hsp90 and the presence or levels of rheumatoid factor. It is thus clear that the disease-specific occurrence of autoantibodies to hsp90 in adult SLE patients [1] and MRL/lpr mice [2] cannot be accounted for by the presence of RF. In our studies, we did not examine in detail the immune response to human hsp65. It would ...

21 Herein we report the first human disseminated infection with Nocardia cerradoensis in a 22 renal transplant patient, and isolated after a brain biopsy. Species identification was based 23 on 16S rRNA, gyrB and hsp65 gene analyses. Antibiotic treatment was successful by 24 combining carbapenems and aminoglycosides, before switching to oral trimethoprim25 sulfamethoxazole. 26

This study evaluated the biodiversity of 28 clinical and 24 environmental Mycobacterium isolates from Rio de Janeiro, Brazil, by using hsp65 sequences, with the aim of contributing to a better understanding of the genetic diversity and usefulness of this marker. An extensive phylogenetic analysis was performed. The nucleotide diversity was similar between clinical (0.06508) and environmental (0...

We report the case of a deep sternal wound infection with sternal osteomyelitis caused by Gordonia bronchialis after open-heart surgery. The isolate was identified as a G. bronchialis by 16S rRNA and hsp65 gene sequencing, having initially been misidentified as a Rhodococcus by a commercial phenotypic identification system.

Mycobacterium szulgai, described for the first time in 1972, is a rare human pathogen that mainly causes pulmonary non-tubercular mycobacteriosis. We report its isolation and identification from a bronchoalveolar lavage specimen by hsp65 gene sequencing analysis in an HIV-positive patient with non-Hodgkin's lymphoma.

Mycobacteria include a large number of pathogens. Identification to species level is important for diagnoses and treatments. Here, we report the development of a Web-accessible database of the hsp65 locus sequences (http://msis.mycobacteria.info) from 149 out of 150 Mycobacterium species/subspecies. This database can serve as a reference for identifying Mycobacterium species.

The phylogenetically conserved nature of heat shock proteins (Hsp) has led to the proposition that they may provide a link between infection and the inflammatory component to vascular disease. Hypertension is associated with atherosclerosis. Here, we measured circulating heat shock protein and heat shock protein antibody levels in association with borderline hypertension. Seventy-two men with b...

Here we report in a human, a renal transplant patient, the first disseminated infection with Nocardia cerradoensis, isolated after a brain biopsy. Species identification was based on 16S rRNA, gyrB, and hsp65 gene analyses. Antibiotic treatment was successful by combining carbapenems and aminoglycosides and then switching to oral trimethoprim-sulfamethoxazole.
