Background and Aim: At the present time one of the strategies in vaccine design is generation of fusion proteins containing (including) immunogen of infectious agents and adjuvants. In this study design and construction of E2-fliC fragment as a vaccine candid was conducted by using fliC gene from Salmonella enterica and E2 gene from hepatitis C virus. Materials and Methods: To prepare the E2-f...
Vaccine reactogenicity has complicated the development of safe and effective live, oral cholera vaccines. Delta ctx Vibrio cholerae mutants have been shown to induce inflammatory diarrhea in volunteers and interleukin-8 (IL-8) production in cultured intestinal epithelial cells. Bacterial flagellins are known to induce IL-8 production through Toll-like receptor 5 (TLR5). Since the V. cholerae ge...
Recently, genome sequencing of many isolates of genetically monomorphic bacterial human pathogens has given new insights into pathogen microevolution and phylogeography. Here, we report a genome-based micro-evolutionary study of a bacterial plant pathogen, Pseudomonas syringae pv. tomato. Only 267 mutations were identified between five sequenced isolates in 3,543,009 nt of analyzed genome seque...
The protein monomer of bacterial flagella, FliC, is known to stimulate human innate immunity through activation of Toll-like receptor five. Linking native Salmonella FliC with various antigens has demonstrated an increased immune response as compared to single antigen presentation. To drastically reduce production time and allow for a more cost effective recombinant vaccine adjuvant, a syntheti...
Background and Objective: Pseudomonas aeruginosa is an opportunistic pathogen that causes severe and lethal infections in immunocompromised individuals. This bacterium possesses a single polar flagellum. Flagellum and its subunit Flagellin play important roles in the pathogenesis of P. aeruginosa. Flagellin induces immune responses by interaction of its N-terminal domain with TLR-5. Our main ai...
Accurate and rapid typing of pathogens is essential for effective surveillance and outbreak detection. Conventional serotyping of Escherichia coli is a delicate, laborious, time-consuming, and expensive procedure. With whole-genome sequencing (WGS) becoming cheaper, it has vast potential in routine typing and surveillance. The aim of this study was to establish a valid and publicly available to...
Little is known about the molecular mechanism by which histone-like nucleoid-structuring (H-NS) protein and cyclic AMP-catabolite activator protein (CAP) complex control bacterial motility. In the present paper, we show that crp and hns mutants are nonmotile due to a complete lack of flagellin accumulation. This results from a reduced expression in vivo of fliA and fliC, which encode the specif...
We present a complete hardware and software system for collecting and quantifying continuous measures of feeding behaviors in the fruit fly, Drosophila melanogaster. The FLIC (Fly Liquid-Food Interaction Counter) detects analog electronic signals as brief as 50 µs that occur when a fly makes physical contact with liquid food. Signal characteristics effectively distinguish between different type...
