effects of climate change on ticks and tick-borne diseases in europe.zoonotic tick-borne diseases are an increasing health burden in europe and there is speculation that this is partly due to climate change affecting vector biology and disease transmission. data on the vector tick ixodes ricinus suggest that an extension of its northern and altitude range has been accompanied by an increased prevalence of tick-borne encephalitis. climate change may also be partly responsible for the change in distribution of dermacentor reticulatus. increased winter activity of i ...200919277106
chronic urticaria in adults: state-of-the-art in the new millennium.chronic urticaria has been explored in several investigative aspects in the new millennium, either as to its pathogenesis, its stand as an autoimmune or auto-reactive disease, the correlation with hla-linked genetic factors, especially with class ii or its interrelation with the coagulation and fibrinolysis systems. new second-generation antihistamines, which act as good symptomatic drugs, emerged and were commercialized over the last decade. old and new drugs that may interfere with the pathoph ...025672302
mites and other indoor allergens - from exposure to sensitization and treatment.house dust mites, cats and dogs are amongst the most frequent sources of indoor allergens in europe. the fact that the allergens of house dust mites cause allergic disease through inhalation of house dust was discovered in 1964. the diagnosis of mite allergy is regularly complicated by its often nonspecific symptoms, which frequently develop insidiously and by no means always include attacks of paroxysmal sneezing and itching. antibody-based immunological detection methods can be used to measure ...201526120549
punique virus, a novel phlebovirus, related to sandfly fever naples virus, isolated from sandflies collected in tunisia.sandflies are widely distributed around the mediterranean basin. therefore, human populations in this area are potentially exposed to sandfly-transmitted diseases, including those caused by phleboviruses. whilst there are substantial data in countries located in the northern part of the mediterranean basin, few data are available for north africa. in this study, a total of 1489 sandflies were collected in 2008 in tunisia from two sites, bioclimatically distinct, located 235 km apart, and identif ...201020089800
interfaces between allergen structure and diagnosis: know your epitopes.allergy diagnosis is based on the patient's clinical history and can be strengthened by tests that confirm the origin of sensitization. in the past 25 years, these tests have evolved from the exclusive in vivo or in vitro use of allergen extracts, to complementary molecular-based diagnostics that rely on in vitro measurements of ige reactivity to individual allergens. for this to occur, an increase in our understanding of the molecular structure of allergens, largely due to the development of te ...025750181

differences in prevalence of borrelia burgdorferi and anaplasma spp. infection among host-seeking dermacentor occidentalis, ixodes pacificus, and ornithodoros coriaceus ticks in northwestern california.previous studies revealed that the pacific coast tick (dermacentor occidentalis) is infected occasionally with the agents of lyme disease (borrelia burgdorferi) or human granulocytic anaplasmosis (anaplasma phagocytophilum) and that it is an inefficient experimental vector of b. burgdorferi. the relationship of the pajahuello tick (ornithodoros coriaceus) to each of these bacterial zoonotic agents has not been reported. the primary bridging vector of both bacterial zoonotic agents to humans is t ...201021359090
the relevance of tick bites to the production of ige antibodies to the mammalian oligosaccharide galactose-a-1,3-galactose.in 2009, we reported a novel form of delayed anaphylaxis to red meat that is related to serum ige antibodies to the oligosaccharide galactose-a-1,3-galactose (alpha-gal). most of these patients had tolerated meat for many years previously. the implication is that some exposure in adult life had stimulated the production of these ige antibodies.201121453959
ixodes ricinus tick lipocalins: identification, cloning, phylogenetic analysis and biochemical characterization.during their blood meal, ticks secrete a wide variety of proteins that interfere with their host's defense mechanisms. among these proteins, lipocalins play a major role in the modulation of the inflammatory response.200819096708
implication of haematophagous arthropod salivary proteins in host-vector interactions.the saliva of haematophagous arthropods contains an array of anti-haemostatic, anti-inflammatory and immunomodulatory molecules that contribute to the success of the blood meal. the saliva of haematophagous arthropods is also involved in the transmission and the establishment of pathogens in the host and in allergic responses. this survey provides a comprehensive overview of the pharmacological activity and immunogenic properties of the main salivary proteins characterised in various haematophag ...201121951834
tick bites and red meat allergy.a novel form of anaphylaxis has been described that is due to ige antibody (ab) directed against a mammalian oligosaccharide epitope, galactose-alpha-1,3-galactose (alpha-gal). ongoing work regarding the cause and distribution of this ige response is reviewed.201323743512
ticks infesting humans in italy and associated pathogens.ticks may transmit a large variety of pathogens, which cause illnesses in animals and humans, commonly referred to as to tick-borne diseases (tbds). the incidence of human tbds in italy is underestimated because of poor surveillance and the scant amount of studies available.201425023709
interactions between tick and transmitted pathogens evolved to minimise competition through nested and coherent networks.natural foci of ticks, pathogens, and vertebrate reservoirs display complex relationships that are key to the circulation of pathogens and infection dynamics through the landscape. however, knowledge of the interaction networks involved in transmission of tick-borne pathogens are limited because empirical studies are commonly incomplete or performed at small spatial scales. here, we applied the methodology of ecological networks to quantify >14,000 interactions among ticks, vertebrates, and path ...201525993662
anaphylaxis to the carbohydrate side chain alpha-gal.in 2007, the monoclonal antibody cetuximab caused severe hypersensitivity reactions during the first infusion in a region of the southeastern united states. investigation of pretreatment sera established that they contained immunoglobulin (ig) e against the oligosaccharide galactose-alpha-1,3-galactose (alpha-gal), which is present on the fab of cetuximab. alpha-gal is a blood group substance of nonprimate mammals. these ige antibodies are also associated with delayed anaphylaxis to red meat (ie ...201525841549
the alpha-gal story: lessons learned from connecting the dots.anaphylaxis is a severe allergic reaction that can be rapidly progressing and fatal, and therefore establishing its cause is pivotal to long-term risk management. our recent work has identified a novel ige antibody response to a mammalian oligosaccharide epitope, galactose-alpha-1,3-galactose (alpha-gal). ige to alpha-gal has been associated with 2 distinct forms of anaphylaxis: (1) immediate-onset anaphylaxis during first exposure to intravenous cetuximab and (2) delayed-onset anaphylaxis 3 to ...201525747720

dermatosis caused by corythuca ciliata (say, 1932) (heteroptera, tingidae). diagnostic and clinical aspects of an unrecognized pseudoparasitosis.the present article discusses three cases of human infestation by corythuca ciliata (lace bugs), a parasite of plane trees. the cases were all in the piedmont region of northwest italy and the symptoms involved a large number of hives on the subjects' bodies which were scarcely or not at all itchy and which spontaneously cleared up in all the cases in less than 24 hours. it can be concluded that the lace bug can be an agent of insect-caused dermatosis and this should be considered in examining s ...024397008
anaphylaxis syndromes related to a new mammalian cross-reactive carbohydrate determinant.anaphylaxis is a severe allergic reaction that can rapidly progress and occasionally be fatal. in instances in which the triggering allergen is not obvious, establishing the cause of anaphylaxis is pivotal to long-term management. assigning cause is limited, however, by the number of known exposures associated with anaphylaxis. therefore identification of novel causative agents can provide an important step forward in facilitating new, allergen-specific approaches to management. in contrast to t ...019815111
flying ticks: anciently evolved associations that constitute a risk of infectious disease spread.ticks are important vectors of emerging zoonotic diseases affecting human and animal health worldwide. ticks are often found on wild birds, which have been long recognized as a potential risk factor for dissemination of ticks and tick-borne pathogens (tbp), thus raising societal concerns and prompting research into their biology and ecology. to fully understand the role of birds in disseminating some ticks species and tbp, it is important to consider the evolutionary relationships between birds, ...201526467109
the new locality of argas reflexus fabricius, 1794 in warsaw, poland.the new locality of argas reflexus in warsaw, poland is recorded. the ticks occur in the lof of apartment blocks, inhabited by pigeons. when the birds were removed by cleaning services, the ticks began to look for a new host and penetrate the flats. some of the lodgers had been bitten by tick larvae and nymphs.200717912811
