Retrospective study of 668 cultures for mycobacteria in a reference hospital for AIDS in Southern Brazil

Brazilian Journal of Infectious Diseases, 2003
Although AIDS patients in other countries are frequently diagnosed as having atypical mycobacterial infection, in Southern Brazil there is a clinical impression that Mycobacterium tuberculosis is the rule rather than the exception.

Polyesterase activity and thermostability of carboxylesterases from Thermoleophilum album YS‐3

The FEBS Journal, EarlyView.
Three novel α/β‐hydrolases from thermophilic bacterium Thermoleophilum album display carboxylesterase and polyesterase activity. These enzymes hydrolyse PET, PLA and PCL both at high and moderate temperatures. TA21 shows superior activity, efficiently converting MHET to terephthalic acid. Structural features underlying substrate binding highlight their

Mycobacterium avium Subsp. paratuberculosis and Human Endogenous Retrovirus in Italian Patients With Inflammatory Bowel Disease (IBD) and Irritable Bowel Syndrome (IBS)

Immunology, EarlyView.
Inflammatory bowel disease (IBD), comprising ulcerative colitis (UC) and Crohn's disease (CD), is a recognised gastrointestinal disorder. Mycobacterium avium subspecies paratuberculosis (MAP) is implicated in IBD pathogenesis. Persistent exposure and active infections by MAP may contribute to the unsilencing of human endogenous retroviruses (HERV ...

Tissue Resident Memory Cells: Friend or Foe?

Immunology, EarlyView.
Tissue‐resident memory T cells (TRM cells) are specialised immune cells in barrier tissues like the lungs, skin and gut, providing rapid host defence and tumour surveillance. Their retention and differentiation are regulated by molecules such as CD69, CD103 and TGF‐β. Dysregulation of TRM cells can lead to chronic activation, driving conditions such as

Blood Immunopathology of Tuberculosis Patients Disrupts Monocyte‐Dependent T‐Cell Activation and Cytokine Expression

Immunology, EarlyView.
TB serum selectively disrupts monocyte‐dependent PHA T cell activation and cytokines associated with proliferation while preserving SEB T cell and Pam3/PHA monocyte cytokine responses. ABSTRACT Pulmonary tuberculosis in humans is characterised by features of immunopathology, which influence both antimycobacterial therapy and the long‐term prognosis. In
