Spore-forming probiotic bacteria offer interesting properties as they have an intrinsic high stability, and when consumed, they are able to survive the adverse conditions encountered during the transit thorough the host gastrointestinal (GI) tract. A traditional healthy food, nattō, exists in Japan consisting of soy fermented by the spore-forming bacterium natto. The consumption of nattō is linked to many beneficial health effects, including the prevention of high blood pressure, osteoporosis, and cardiovascular-associated disease.

However, regulation of biofilm development and its persistence in different niches is complex and only partially understood. One key step during the biofilm life cycle is dispersal, when motile cells abandon the mature biofilm to spread out and colonize new niches.

Materials and methods Blood samples were obtained from 31 HIV-infected patients (15 IRIS-P and 16 non-IRIS-P) before ART (BT) and 48 ± 2 weeks after treatment initiation (AT). Plasma Interleukin-6 (IL-6) and Interleukin-18 (IL-18) were determined by ELISA.

Considering that NO, TNF-alpha and TGF-beta participate a great deal in TB immunopathogenesis, we wished to analyse whether these mediators showed some relationship with the degree of pulmonary affectation. The sample comprised 29 TB (HIV-), inpatients with mild-moderate (n = 10) or advanced (n = 19) newly-diagnosed disease, together with 12 healthy controls HCo.
View Article and Find Full Text PDFOur study investigated whether the respiratory burst (RB) of polymorphonuclear neutrophils from tuberculosis (TB) patients was related with the disease severity or treatment, as well as the circulating levels of TNF-alpha. The sample comprised 57 patients with moderate (n=21) or advanced disease (n=36, 13 of them with HIV coinfection, TB-HIV) and 12 controls. Patients were newly diagnosed (n=27) or under treatment (moderate=14, advanced=10, TB-HIV=6).
