In this study we describe the in vivo biosynthesis of two novel conjugate vaccine candidates against Shigella dysenteriae type 1, an important bacterial pathogen causing severe gastro-intestinal disease states mainly in developing countries. (biomedcentral.com)

As part of a double blind randomized-controlled field trial of the effectiveness of permethrin-treated clothing in preventing tick bites, we identified tick species removed from the skin of outdoor workers in North Carolina and tested the ticks for Rickettsiales pathogens. (cdc.gov)
METHODS: Ticks submitted by study participants from April-September 2011 and 2012 were identified to species and life stage, and preliminarily screened for the genus Rickettsia by nested PCR targeting the 17-kDa protein gene. (cdc.gov)
begingroup$ So they are just under trial and aren't used as prophylaxis because 1) of the differences in core groups of the LPS of the same bacterial species. (stackexchange.com)
So, speaking prophylactically , the vaccine will be effective against only one strain of that bacterial species and not as whole. (stackexchange.com)
A significant number of bacterial species encode multiple copies of the filament building block - flagellin. (ncl.ac.uk)
We complement our study on flagellar abundance with research to understanding how a filament is assembled from multiple flagellins, a trait maintained by many bacterial species. (ncl.ac.uk)
Many proteins, largely derived from Bacteroides species, were over-represented, while under-represented proteins were mostly from Firmicutes and some Prevotella members. (bmj.com)
PBS dilutions of sonicated bacterial extracts derived from each of the above species were brought to an optical density of 1, using a spectrophotometer (Ultrospec III, Pharmacia, Sweden) set at a wavelength of 600 nm. (cdc.gov)

The structure-function analysis of TarP forms an excellent basis for the development of new drugs that block TarP, allowing the immune system to detect the pathogens again. (mpg.de)

Immunoradiometric assays show that host erythrocyte antigen is lost from adult worm tegument with a half-life of up to 45 hours in vitro and ~5 days in vivo [ 493 ]. (nanomedicine.com)
For bacterial in vivo characterization, we evaluate the biological relevance of our targets in the host-microbe interaction: we use genome site directed mutagenesis, homologous and heterologous complementation with wild-type and mutant versions of the proteins, classical microbiological determination assays (i.e. biofilm formation, EPS content, flagellar apparatus production, motility, survival to stresses, growth, etc). (leloir.org.ar)
For immunological studies, we use different animal and cellular models (i.e. knock-out mice, OT-1 and OT-2 transgenic mice, adoptive transfer of immunity, models of protective and therapeutic vaccine against tumors, in vivo analysis of antigen persistence in cell and tissues). (leloir.org.ar)

There are two types of phospholipid-membrane-based nanovesicles: pure lipid and/or protein vesicles and comparatively complex cell-membrane-derived vesicles (also called extracellular vesicles (EVs)) [ 1 ] . (encyclopedia.pub)

a: oligosaccharyltransferase PglB, b: carrier protein with signal sequence for secretion to the periplasm, c: undecaprenyl-pyrophosphate-linked polysaccharides. (biomedcentral.com)
Prior to their secretion, IpaB and IpaC are stored in the bacterial cytoplasm where they individually associate with the molecular chaperone IpgC. (ku.edu)
A read-out assay such as 3 H-thymidine incorporation or cytokine secretion is used to identify the targets of antigen-specific responses. (antigendiscovery.com)

However, in the case of some pathogens, sometimes the defensive strategies of the human body fail, especially in immunocompromised patients. (mpg.de)

My laboratory uses, bacterial genetics, protein biochemistry, structural biology, bioinformatics and microscopic techniques to validate our genetic findings. (ncl.ac.uk)
The structural variability of these antigens forms the basis for classification into various serotypes. (medscape.com)
These structural and functional features have been selected for their relevance in protein chemistry, immunology, protein structure and ability to guide the network in discriminating protective versus non-protective antigens. (evaxion-biotech.com)

Moderna is similarly building mRNA therapies that instruct the immune system to recognize mutations made by cancerous proteins in a gene called KRAS . (salon.com)

Additionally, BMVs consist of considerable proteins, for example, original bacterial antigens and pathogen-associated molecular pattern components [ 5 ] . (encyclopedia.pub)

Natural or synthetic lipid and/or protein ingredients make nanovesicles, involving liposomes or proteoliposomes, an ideal model of the membrane system with the advantages of an easy and low-cost production [ 2 ] . (encyclopedia.pub)
Furthermore, cell-derived membrane vesicles are regarded as nano- to micrometer-sized containers comprising components such as cellular proteins, nucleic acids and lipids, for the reason that cell plasma or cytosol membranes can enclose these contents while membrane vesicles are secreted [ 3 ] . (encyclopedia.pub)
They correspond to functions allowing opportunistic pathogens to colonise the mucus layers, breach the host barriers and invade the mucosae, which could still be aggravated by decreased host-derived pancreatic zymogen granule membrane protein GP2 in CD patients. (bmj.com)
This inhibits the formation of the membrane attack complex (C5b-C9), which prevents membrane damage and bacterial cell death. (medscape.com)

4) nucleic acid PCR: detection of cerebrospinal fluid pathogen nucleic acid PCR. (who.int)

The term "typical" CAP refers to a bacterial pneumonia caused by pathogens such as S pneumoniae , H influenzae , and M catarrhalis . (medscape.com)
