[post-lyme disease syndrome]. | lyme disease is a chronic infectious disease caused by the bacteria, spirochete of the borrelia type. skin, nervous system, musculoskeletal system and heart may be involved in the course of the disease. the prognosis for properly treated lyme disease is usually good. however, in about 5% of patients so called post-lyme disease syndrome (plsd) develops. it is defined as a syndrome of subjective symptoms persisting despite proper treatment of borrelia burgdorferi infection. the most common symptom ... | 2016 | 27000820 |
antigenic variation in bacterial pathogens. | antigenic variation is a strategy used by a broad diversity of microbial pathogens to persist within the mammalian host. whereas viruses make use of a minimal proofreading capacity combined with large amounts of progeny to use random mutation for variant generation, antigenically variant bacteria have evolved mechanisms which use a stable genome, which aids in protecting the fitness of the progeny. here, three well-characterized and highly antigenically variant bacterial pathogens are discussed: ... | 2016 | 26999387 |
an unexpected advantage of insectivorism: insect moulting hormones ingested by song birds affect their ticks. | ecdysteroids are important hormones that regulate moulting in arthropods. three-host ixodid ticks normally moult to the next stage after finishing their blood meal, in the off-host environment. presumably, three-host ticks that feed on the blood of insectivorous vertebrate hosts can be exposed to high levels of exogenous ecdysteroids causing them to initiate apolysis (the first step of moulting) on the vertebrate host. the aim of the present study was to investigate whether ticks undergo apolysi ... | 2016 | 26996354 |
salmonella enterica serovar typhimurium utilizes the clppx and lon proteases for optimal fitness in the ceca of chickens. | salmonella enterica serovar typhimurium (s. typhimurium) is a leading cause of salmonellosis. poultry and poultry products are implicated in transmission of salmonella to humans. in 2013, an outbreak of s typhimurium occurred that comprised 39 states within the united states and was associated with backyard flocks of chickens. colonization of the avian host by s typhimurium requires numerous genetic factors encoded within the bacterium. of particular interest are genetic factors induced by alter ... | 2016 | 26994203 |
statins reduce spirochetal burden and modulate immune responses in the c3h/hen mouse model of lyme disease. | lyme disease (ld) is a systemic disorder caused by borrelia burgdorferi. lyme spirochetes encode for a functional 3-hydroxy-3-methyl-glutaryl-coenzyme a reductase (hmgr ec 1.1.1.88) serving as a rate limiting enzyme of the mevalonate pathway that contribute to components critical for cell wall biogenesis. statins have been shown to inhibit b. burgdorferi in vitro. using a mouse model of lyme disease, we found that statins contribute to reducing bacterial burden and altering the murine immune res ... | 2016 | 26993029 |
oral immunization with ospc does not prevent tick-borne borrelia burgdorferi infection. | oral vaccination strategies are of interest to prevent transmission of lyme disease as they can be used to deliver vaccines to humans, pets, and to natural wildlife reservoir hosts of borrelia burgdorferi. we developed a number of oral vaccines based in e. coli expressing recombinant ospc type k, ospb, bbk32 from b. burgdorferi, and salp25, salp15 from ixodes scapularis. of the five immunogenic candidates only ospc induced significant levels of antigen-specific igg and iga when administered to m ... | 2016 | 26990760 |

snake venom disintegrin inhibits the activation of toll-like receptors and alleviates sepsis through integrin alphavbeta3 blockade. | bacterial infection-induced sepsis is the leading cause of septic inflammatory disease. rhodostomin (rn), a snake venom disintegrin, was previously reported to interact with the αvβ3 integrin and the tlr4 on phagocyte in attenuating lps-induced endotoxemia. in this report, we further evaluated the effects of rn on tlr2-activated monocytes and its in vivo efficacy. rn effectively suppressed the adhesion, migration, and cytokine release of pam3csk4-activated thp-1 cells. rn specifically bound to i ... | 2016 | 26987407 |
co-infection of ticks: the rule rather than the exception. | ticks are the most common arthropod vectors of both human and animal diseases in europe, and the ixodes ricinus tick species is able to transmit a large number of bacteria, viruses and parasites. ticks may also be co-infected with several pathogens, with a subsequent high likelihood of co-transmission to humans or animals. however few data exist regarding co-infection prevalences, and these studies only focus on certain well-known pathogens. in addition to pathogens, ticks also carry symbionts t ... | 2016 | 26986203 |
evaluation of serum concentrations of the selected cytokines in patients with localized scleroderma. | localized scleroderma is an autoimmune disease primarily affecting the skin. the cause of disease remains unexplained although environmental factors are implicated, which are likely to be responsible for activation of the endothelium and subsequent inflammation leading to excessive synthesis of collagen and extracellular matrix components. | 2016 | 26985179 |
cd83 modulates b cell activation and germinal center responses. | cd83 is a maturation marker for dendritic cells. in the b cell lineage, cd83 is expressed especially on activated b cells and on light zone b cells during the germinal center (gc) reaction. the function of cd83 during gc responses is unclear. cd83(-/-) mice have a strong reduction of cd4(+) t cells, which makes it difficult to analyze a functional role of cd83 on b cells during gc responses. therefore, in the present study we generated a b cell-specific cd83 conditional knockout (cd83 b-cko) mod ... | 2016 | 26983787 |
