BACKGROUND: While the most nontuberculous mycobacteria (NTMs) species are considered as opportunistic pathogens, some of them are related to several human infections. It is believed that environment is the main source for these infections. Distribution and scattering pattern of NTMs has not been well studied in Iran and a few studies about this subject have been done, so the aim of this study was to determine prevalence of NTMs in environmental samples from Iran. MATERIALS AND METHODS: Data about prevalence of NTMs in environmental samples from Iran were obtained by searching databases...

BACKGROUND: Porphyromonas gingivalis is one of the etiological agents in the initiation of combined periodontal-endodontic (perio-endo) lesions. Successful treatment of perio-endo lesions with photo-activated disinfection (PAD) as a novel therapeutic approach depends on the selection of an appropriate target site, specific photosensitizer (PS), and wavelength of light. Since the fimbrillin (FimA) is the most important pathogenic agent in P. gingivalis it was evaluated as a target site against PAD with toluidine blue O (TBO) as a PS...

Although data visualization tools continue to improve, during the data exploration process many of them require users to manually specify visualization techniques, mappings, and parameters. In response, we present the Visualization by Demonstration paradigm, a novel interaction method for visual data exploration. A system which adopts this paradigm allows users to provide visual demonstrations of incremental changes to the visual representation. The system then recommends potential transformations (Visual Representation, Data Mapping, Axes, and View Specification transformations) from the given demonstrations...

Pseudomonas aeruginosa type IV pili have an essential role in twitching motility, colonization and biofilm formation. In this study, we investigated the efficacy of intraperitoneal administration of rabbit anti-recombinant PilA (anti-r-PilA) immunoglobulin G (IgG) against P. aeruginosa infection in a mouse burn-wound model. After burn and infection, mortality rate was assessed in all mice, and that of mice passively immunized with rabbit anti-r-PilA IgG was compared to non-immunized mice. Bacterial quantities in the skin and internal organs were measured to determine the level of systemic infection...

Burn wound infections caused by multidrug-resistant Pseudomonas aeruginosa strains are a serious challenge to therapy because of the complex pathogenesis and paucity of new effective antibiotics. Therefore, there is renewed interest in developing antibody-based therapeutic strategies. Immunotherapy strategies typically target selected virulence factors that are expressed by the majority of clinical strains of P. aeruginosa, particularly because virulence factors mediate infection. Here we used a murine model of burn wound infection to evaluate the efficacy of antibodies raised against the divalent type b flagellin and PilA (flagellin b + PilA), as acute virulence factors, to prevent and treat infection...
