Rapid diagnosis for differentiation of leptospirosis from other pyrogenic infections prevailing in the same locality is imperative for proper treatment. During infection, the pathogenic Leptospira spp. express virulence factors which induce antibody responses in the infected host. In this study, 50 referenced Leptospira spp. belonging to six genomospecies(More)
Susceptibility to Mycobacterium tuberculosis is characterized by excessive lung inflammation, tissue damage, and failure to control bacterial growth. To increase our understanding of mechanisms that may regulate the host immune response in the lungs, we characterized dendritic cells expressing CD103 (α(E) integrin) (αE-DCs) and CD4(+) Foxp3(+) regulatory T(More)
Tuberculosis (TB) has emerged as the most prominent bacterial disease found in human immunodeficiency virus (HIV)-positive individuals worldwide. Due to high prevalence of asymptomatic Mycobacterium tuberculosis (Mtb) infections, the future HIV vaccine in areas highly endemic for TB will often be administrated to individuals with an ongoing Mtb infection.(More)
External quality assessment for evaluation of individual competency in isolation and identification of bacteria for clinical microbiological laboratory was studied. Lyophilized or freezedried bacteria were prepared and a panel of lyophilized bacteria was shipped once a year. The first set consisted of two mixed cultures and one pure culture. Forty-three(More)
Non-hematopoietic cells, including lung epithelial cells, influence host immune responses. By co-culturing primary alveolar epithelial cells and monocytes from naïve donor mice, we show that alveolar epithelial cells support monocyte survival and differentiation in vitro, suggesting a role for non-hematopoietic cells in monocyte differentiation during the(More)
