Date: July 12, 2021 Issue #:  1628Summary:  The Centers for Disease Control and Prevention (CDC) and the Environmental Protection Agency (EPA) recommend using insect repellents to prevent infections transmitted by mosquitoes and ticks. Insect repellents applied to exposed skin should be used in conjunction with other preventive measures such as wearing pants and long-sleeved shirts and avoiding outdoor activities during peak mosquito-biting times. Mosquitoes can transmit diseasecausing pathogens, including Zika, chikungunya, dengue, West Nile, eastern equine encephalitis, and yellow fever virus...

In this study, we selected four representative tick species which have different regional distribution foci in mainland China. i.e., Dermacentor marginatus, Dermacentor silvarum, Haemaphysalis longicornis and Ixodes granulatus. We used the MaxEnt model to identify the key environmental factors of tick occurrence and map their potential distributions in 2050 under four combined climate and socioeconomic scenarios (i.e., SSP1-RCP2.6, SSP2-RCP4.5, SSP3-RCP7.0 and SSP5-RCP8.5). We found that the extent of the urban fabric, cropland and forest, temperature annual range and precipitation of the driest month were the main determi...

CONCLUSION: The results of our study will support public health authorities and decision-makers in targeting those sectors and occupations that are particularly at risk for the acquisition of zoonoses. Doing so will ultimately optimize the public health practices of those responsible for the health of workers.PMID:33679248 | PMC:PMC7919776 | DOI:10.14745/ccdr.v47i01a08

Tick saliva is a rich source of pharmacologically and immunologically active molecules. These salivary components are indispensable for successful blood feeding on vertebrate hosts and are believed to facilitate the transmission of tick-borne pathogens. Here we present the functional and structural characterization of Iripin-3, a protein expressed in the salivary glands of the tick Ixodes ricinus, a European vector of tick-borne encephalitis and Lyme disease. Belonging to the serpin superfamily of protease inhibitors, Iripin-3 strongly inhibited the proteolytic activity of serine proteases kallikrein and matriptase. In an ...

ávez Ticks are obligate hematophagous parasites and are important vectors of a wide variety of pathogens. These pathogens include spirochetes in the genus Borrelia that cause Lyme disease, rickettsial pathogens, and tick-borne encephalitis virus, among others. Due to their prolonged feeding period of up to two weeks, hard ticks must counteract vertebrate host defense reactions in order to survive and reproduce. To overcome host defense mechanisms, ticks have evolved a large number of pharmacologically active molecules that are secreted in their saliva, which inhibits or modulates host immune defenses and wound h...

Pediatric bilateral facial nerve paralysis (FNP) is a rare condition, representing less than 2% of all cases of FNP. The differential diagnosis of FNP is extensive (ranging from infectious, traumatic, neurologic, to idiopathic) and often can present as a diagnostic challenge. In contrast to unilateral presentation, bilateral FNP presents as a manifestation of serious systemic conditions, including meningitis (infectious and neoplastic), brain stem encephalitis, Guillain-Barre syndrome, sarcoidosis, Lyme disease, human immunodeficiency virus infection, leukemia, and vasculitis. In the evaluation of a child who presents with...

In this study, we modelled the spatial distribution of I. ricinus and associated Chlamydiales over Switzerland from 2009 to 2019. We used a total of 2293 ticks and 186 Chlamydiales occurrences provided by a Swiss Army field campaign, a collaborative smartphone application and a prospective campaign. For each tick location, we retrieved from Swiss federal datasets the environmental factors reflecting the topography, climate and land cover. We then used the Maxent modelling technique to estimate the suitability for I. ricinus and to subsequently build the nested niche of Chlamydiales bacteria. Results indicate that I. ricinu...

Abstract Companion animals can become infected with tick-borne diseases (TBDs) and can become hosts of transmission to humans, thereby damaging human health. To clarify whether companion animals are infested by ticks harboring TBD pathogens in humans, we detected TBD pathogens in ticks collected from dogs and cats brought to animal hospitals in Yamagata Prefecture, Japan. Investigation of 164 adult ticks collected from 88 dogs and 41 cats during March-July 2018 revealed the predominant tick species as Ixodes ovatus (n = 95, 57.9%), followed by Ixodes nipponensis (37, 22.6%) and Haemaphysalis flava (10, 6.1%). The ...
