Mechanisms of arthropod transmission of plant and animal viruses. (1/307)

A majority of the plant-infecting viruses and many of the animal-infecting viruses are dependent upon arthropod vectors for transmission between hosts and/or as alternative hosts. The viruses have evolved specific associations with their vectors, and we are beginning to understand the underlying mechanisms that regulate the virus transmission process. A majority of plant viruses are carried on the cuticle lining of a vector's mouthparts or foregut. This initially appeared to be simple mechanical contamination, but it is now known to be a biologically complex interaction between specific virus proteins and as yet unidentified vector cuticle-associated compounds. Numerous other plant viruses and the majority of animal viruses are carried within the body of the vector. These viruses have evolved specific mechanisms to enable them to be transported through multiple tissues and to evade vector defenses. In response, vector species have evolved so that not all individuals within a species are susceptible to virus infection or can serve as a competent vector. Not only are the virus components of the transmission process being identified, but also the genetic and physiological components of the vectors which determine their ability to be used successfully by the virus are being elucidated. The mechanisms of arthropod-virus associations are many and complex, but common themes are beginning to emerge which may allow the development of novel strategies to ultimately control epidemics caused by arthropod-borne viruses.  (+info)

Genetic and fitness changes accompanying adaptation of an arbovirus to vertebrate and invertebrate cells. (2/307)

The alternating host cycle and persistent vector infection may constrain the evolution of arboviruses. To test this hypothesis, eastern equine encephalitis virus was passaged in BHK or mosquito cells, as well as in alternating (both) host cell passages. High and low multiplicities were used to examine the effect of defective interfering particles. Clonal BHK and persistent mosquito cell infections were also evaluated. Fitness was measured with one-step growth curves and competition assays, and mutations were evaluated by nucleotide sequencing and RNA fingerprinting. All passages and assays were done at 32 degrees C to eliminate temperature as a selection factor. Viruses passaged in either cell type alone exhibited fitness declines in the bypassed cells, while high-multiplicity and clonal passages caused fitness declines in both types of cells. Bypassed cell fitness losses were mosquito and vertebrate specific and were not restricted to individual cell lines. Fitness increases occurred in the cell line used for single-host-adaptation passages and in both cells for alternately passaged viruses. Surprisingly, single-host-cell passage increased fitness in that cell type no more than alternating passages. However, single-host-cell adaptation resulted in more mutations than alternating cell passages. Mosquito cell adaptation invariably resulted in replacement of the stop codon in nsP3 with arginine or cysteine. In one case, BHK cell adaptation resulted in a 238-nucleotide deletion in the 3' untranslated region. Many nonsynonymous substitutions were shared among more than one BHK or mosquito cell passage series, suggesting positive Darwinian selection. Our results suggest that alternating host transmission cycles constrain the evolutionary rates of arboviruses but not their fitness for either host alone.  (+info)

Establishment and characterization of a new continuous cell line from Lutzomyia longipalpis (Diptera: psychodidae) and its susceptibility to infections with arboviruses and Leishmania chagasi. (3/307)

Embryonic tissue explants of the sand fly Lutzomyia longipalpis (Lutz & Neiva 1912) the main vector of Leishmania chagasi (Cunha and Chagas), were used to obtain a continuous cell line (Lulo). The tissues were seeded in MM/VP12 medium and these were incubated at 28 masculineC. The first subculture was obtained 45 days after explanting and 96 passages have been made to date. Lulo is composed of epithelioid cells, showed a 0.04 generations/hour exponential growth rate and population doubling time at 24.7 h. The cell line isoenzymatic profiles were determined by using PGI, PGM, MPI and 6-PGDH systems, coinciding with patterns obtained from the same species and colony's pupae and adults. The species karyotype characteristics were recognized (2n = 8), in which pair 1 is subtelocentric and pairs 2, 3 and 4 are metacentric. Lulo was free from bacterial, fungal, mycoplasmic and viral infection. Susceptibility to five arbovirus was determined, the same as Lulo interaction with Leishmania promastigotes.  (+info)

Complete sequence determination and genetic analysis of Banna virus and Kadipiro virus: proposal for assignment to a new genus (Seadornavirus) within the family Reoviridae. (4/307)

Arboviruses with genomes composed of 12 segments of double-stranded (ds) RNA have previously been classified as members or probable members of the genus Coltivirus within the family REOVIRIDAE: A number of these viruses have been isolated in North America and Europe and are serologically and genetically related to Colorado tick fever virus, the Coltivirus type species. These isolates constitute subgroup A of the coltiviruses. The complete genome sequences are now presented of two Asian arboviruses, Kadipiro virus (KDV) and Banna virus (BAV), which are currently classified as subgroup B coltiviruses. Analysis of the viral protein sequences shows that all of the BAV genome segments have cognate genes in KDV. The functions of several of these proteins were also indicated by this analysis. Proteins with dsRNA-binding domains or with significant similarities to polymerases, methyltransferases, NTPases or protein kinases were identified. Comparisons of amino acid sequences of the conserved polymerase protein have shown that BAV and KDV are only very distantly related to the subgroup A coltiviruses. These data demonstrate a requirement for the subgroup B viruses to be reassigned to a separate new genus, for which the name Seadornavirus is proposed.  (+info)

Kaeng Khoi virus from naturally infected bedbugs (cimicidae) and immature free-tailed bats. (5/307)

Snail control in urban sites in Brazil with slow-release hexabutyldistannoxane and pentachlorophenol. (6/307)

Slow release formulations of hexabutyldistannoxane (TBTO) and pentachlorophenol (PCP) were tested for the control of Biomphalaria tenagophila in 52 urban sites in Rio de Janeiro. TBTO acted faster and lasted longer than PCP and at 15 g/m(2) it eliminated snails from 76% of the treated sites for 1 year. Water pollution and rate of flow had no significant influence on the molluscicidal properties of either compound, but alkalinity lowered the activity of TBTO. Failure to control snail populations was due mainly to human interference and to the non-treatment of adjacent breeding sites that were temporarily dry and therefore overlooked.  (+info)

Assay of togavirus haemagglutination-inhibition antibodies by the micro method: loss of information and its rectification. (7/307)

Haemagglutination inhibition (HI) activity was assayed by the micro and macro methods in immune sera prepared against four togaviruses. HI titres were always 4 to 8 times lower by the micro method, and coincided with 4 to 8 times lower haemagglutinin titres in micro method assays. Because of this phenomenon, positive sera with HI macro method titres lower than 1: 80 will be false negative for HI by the micro method when tests begin at a 1: 10 serum dilution. This was confirmed for a number of human sera tested for West Nile virus HI activity. As a consequence of the difference between titres given by the two assay methods, results of seroepidemiological studies may be distorted. Use of a system that combines both the macro and micro methods could rectify this distortion.  (+info)

Inhibition of group B arbovirus antigen production and replication in cells enucleated with cytochalasin B. (8/307)

A comparative study of the growth of Sindbis (SIN) virus, a group A arbovirus (togavirus), and Japanese encephalitis (JE) virus, a representative group B arbovirus (togavirus), was conducted in enucleate and nucleate cells. Immunofluorescent tests and yield measurements demonstrated that chicken embryo cells which had been enucleated and subsequently infected with SIN virus produced virus-specific antigens and infectious virus. By contrast, JE failed to replicate or produce virus-specific antigen in cells which had been enucleated before or even 2 h post infection. Studies of the effect of enulceation at various times after infection demonstrated that a nucleus must be present at least 2 and possibly as long as 4 h after infection to produce either JE-specific antigen or infectious JE virus. These studies demonstrate that the replication of SIN, a group A arbovirus (togavirus), which has no nuclear requirement, contrasts sharply with that of a group B arbovirus (togavirus), JE, which may have an initial dependence on a nucleus-associated process.  (+info)

Slave trading of Africans to the Americas, during the 16th to the 19th century was responsible for the first recorded emergence in the New World of two arthropod-borne viruses (arboviruses), yellow fever virus and dengue virus. Many other arboviruses have since emerged from their sylvatic reservoirs and dispersed globally due to evolving factors that include anthropological behaviour, commercial transportation and land-remediation. Here, we outline some characteristics of these highly divergent arboviruses, including the variety of life cycles they have developed and the mechanisms by which they have adapted to evolving changes in habitat and host availability. We cite recent examples of virus emergence that exemplify how arboviruses have exploited the consequences of the modern human lifestyle. Using our current understanding of these viruses, we also attempt to demonstrate some of the limitations encountered in developing control strategies to reduce the impact of future emerging arbovirus ...
Arthropod-borne viruses (arboviruses) are important human pathogens for which there are no specific antiviral medicines. The abundance of genetically distinct arbovirus species, coupled with the unpredictable nature of their outbreaks, has made the development of virus-specific treatments challenging. Instead, we have defined and targeted a key aspect of the host innate immune response to virus at the arthropod bite that is common to all arbovirus infections, potentially circumventing the need for virus-specific therapies. Using mouse models and human skin explants, we identify innate immune responses by dermal macrophages in the skin as a key determinant of disease severity. Post-exposure treatment of the inoculation site by a topical TLR7 agonist suppressed both the local and subsequent systemic course of infection with a variety of arboviruses from the Alphavirus, Flavivirus, and Orthobunyavirus genera. Clinical outcome was improved in mice after infection with a model alphavirus. In the ...
Arthropod-borne viruses, or arboviruses, are viruses that are transmitted through the bites of mosquitoes and ticks. There are numerous arboviruses throughout the world capable of causing human disease spanning different viral families and genera. Recently, dengue, chikungunya, and zika viruses have emerged as increasingly important arboviruses that can cause human disease, however no specific treatment or vaccine is available for them. In addition, ocular manifestations of these diseases have become more prevalent over the past few years. This review highlights the current understanding on the pathogenesis, systemic changes and ocular findings, emphasizing the retinal manifestations related to dengue, chikungunya, and zika viruses.
Arboviruses (or arthropod-borne viruses) are a heterogeneous group of viruses that share the same usual route of entry into humans: via the bite of an infected mosquito, tick, sandfly, or other arthropod.1,2 The life cycle of most arboviruses is characterized by the ability of the virus to replicate in both an arthropod vector and a vertebrate natural host (usually birds or small mammals) and by transmission between these two organisms at the time of the arthropods bite (eFig. 305.1). This cycle leads to establishment or maintenance of the virus in a given ecosystem. Humans or domestic animals are only incidental hosts for many species of arboviruses, as infection in such hosts (although capable of causing disease) is often a dead-end for the virus due to viremia being too low or too transient to contribute to maintenance of the cycle of transmission. Some viruses are specific to a single genus or species of insect, while others are transmissible by multiple vectors. In addition, some ...
Summary Cell lines of baby hamster kidney (BHK 21), green monkey kidney (Vero, MA 134), rhesus monkey kidney (MA 104), and rabbit kidney (MA 111) were found suitable for titration and multiplication of arboviruses. Plaque characteristics of 52 arboviruses and 20 virus strains and titres of some of them in BHK 21 and other cell lines were established, using one type of serum-free standard overlay and standard maintenance medium. However, the addition of cortisol or other compounds was necessary to prolong survival of BHK 21 cell sheets, and induce or improve plaque formation.
Extrinsic and environmental factors are known to affect the transmission of arthropod-borne viruses (arboviruses), including variations in the arthropod vector populations. Differences among these factors have been associated with differential transmission and are sometimes used to control the spread of an arbovirus through a vertebrate population in an effort to prevent or disrupt an outbreak. However, diversity in intrinsic viral populations, such as genetic and phenotypic variability, is not often accounted for when considering alterations in transmission. Presented in this dissertation are four experimental studies that explore the contribution of viral intrinsic factors, especially phenotypic variability, to the transmission potential of arboviruses as judged by modeling parameters such as vectorial capacity (VC) and the basic reproductive number (R0). The overall hypothesis of this research is that phenotypic differences of arboviruses alter the transmission potential of these arboviruses by
Arthropod-borne viruses (arboviruses) are important causes of human disease nearly worldwide. All arboviruses circulate among wild animals, and many cause disease after spillover transmission to humans and agriculturally important domestic animals that are incidental or dead-end hosts. Viruses such as dengue (DENV) and chikungunya (CHIKV) that have lost the requirement for enzootic amplification now produce extensive epidemics in tropical urban centers. Many arboviruses recently have increased in importance as human and veterinary pathogens using a variety of mechanisms. Beginning in 1999, West Nile virus (WNV) underwent a dramatic geographic expansion into the Americas. High amplification associated with avian virulence coupled with adaptation for replication at higher temperatures in mosquito vectors, has caused the largest epidemic of arboviral encephalitis ever reported in the Americas. Japanese encephalitis virus (JEV), the most frequent arboviral cause of encephalitis worldwide,
As public health agencies struggle to track and contain emerging arbovirus threats, timely and efficient surveillance is more critical than ever. Using historical dengue data from Puerto Rico, we developed methods for streamlining and designing novel arbovirus surveillance systems with or without historical disease data.
Arboviruses are a group of viruses that are transmitted by insects to humans. Examples include yellow fever, West Nile virus, and Japanese encephalitis.

Emeritus Professor Duane Gubler is an international expert on vector borne-infectious diseases and a go-to spokesperson for the media for all things infectious disease-related. This year alone he has been interviewed by The New York Times, The Straits Times, and Vox, among other media outlets.. Arboviruses: Molecular Biology, Evolution and Control on arboviruses, a well-received book edited by Prof Gubler, looks at viruses that are transmitted by arthropod vectors, such as mosquitoes, flies, sand flies, lice, fleas, ticks and mites. Since Zika was declared a major global emergency last year, and dengue remains a consistent health threat and concern, the text is a much welcome contribution to the literature on these groups of viruses..

Key Public Risk Communication Messages for the Week of Sept 24, 2012:. 1. Day time and early evening temperatures are still warm enough for continued mosquito activity. Mosquito activity drops off when temperatures are below 60 but some mosquitoes will be active even down to 52 degrees.. 2. At this time of year, the mosquitoes that remain are older adults; as mosquitoes age, they are more likely to have picked up either EEE or WNV so a greater proportion of them are probably infected. Because of cooler temperatures, mosquito trapping is less effective and the increased infection rates are not always obvious based on mosquito testing results.. 3. Communities at high or critical risk for EEE are urged to consider rescheduling outdoor, evening events that occur between the hours of dusk and dawn. Communities at high or critical risk for WNV should consider outreach to residents over the age of 50 with information about peak mosquito activity hours.. ...
Overview: Epidemiology of arthropod-borne and other zoonotic viral diseases. Research Interests. My primary research interests are on the epidemiology and pathogenesis of arthropod-borne and zoonotic viral diseases. Most of my work involves field studies of the ecology of the viruses and laboratory investigations on their pathology in animals.

This is a large collection, which includes most of the known arboviruses as well as reagents (antibodies and antigens) for them. These are distributed at no cost to qualified investigators throughout the world. The Reference Collection is an invaluable resource for persons interested in comparative studies of viral interrelationships and pathogenicity. We also receive unknown virus samples for identification and characterization. Recent Publications. Search PubMed Database for Publications SciVal Publications Overview ...
This study is, to the authors knowledge, the first survey of mosquito species on equine premises in the UK. This work has demonstrated the presence of several mosquito species that are candidate vectors of pathogens affecting horses. Commonly found mosquito species on equine premises during this study included Oc. detritus, Oc. caspius, Cs. annulata, Cx. pipiens s.l., Cx. torrentium, An. claviger, An. plumbeus and Oc. punctor. Although mosquito density could be considered low at most of the sites sampled, this could be partly explained by the fact that the months of March, April and May in 2015 were relatively dry for all of the regions except the northwest (Met Office 2016). Climate change predictions suggest increased temperature and potential for flooding events in the UK (Met Office 2010, Caminade and others 2012, Medlock and Leach 2015), which are likely to increase the abundance of native mosquito species. It therefore seems likely that in the future there may be significantly increased ...
Stagnant and warmer waters are conducive to the proliferation of arboviruses, these diseases transmitted by mosquitoes or ticks, which like humidity and heat.. Currently, worldwide, arboviruses (diseases transmitted by mosquitoes and ticks) represent more than 40% of infectious and emerging diseases. They include dengue fever which has the highest prevalence in the world, with 390 million persons infected a year, chikungunya, zika virus, yellow fever, etc. The mosquito would thus be responsible for more than 750,000 deaths per year. It remains public enemy number one in many countries, especially as it adapts quickly. Humans cannot completely control the Nature and they are only part of a vast living ecosystem… ...
Diagnostic and epidemiologic virology laboratories have in large part traded conventional techniques of virus detection and identification for more rapid, novel, and sensitive molecular methods. By doing so, useful phenotypic characteristics are not being determined. We feel that the impact of this shift in emphasis has impaired studies of the biology of viruses. This position paper is a plea to the scientific and administrative communities to reconsider the importance of such information. We also suggest a revised paradigm for virus isolation and characterization and provide a rationale for accumulating biologic (phenotypic) information ...

Malaria is a long-standing public health problem in sub-Saharan Africa, whereas arthropod-borne viruses (arboviruses) such as dengue and chikungunya cause an under-recognised burden of disease. Many human and environmental drivers affect the dynamics ...
Arthropod-borne viruses - arboviruses - are a significant threat to public health. Whilst there is considerable knowledge about arbovirus interactions with vertebrate immunity, relatively little is known about how vectors such as mosquitoes control arbovirus infections. In this review, we discuss novel findings in the field of mosquito antiviral responses to arboviruses, in particular RNA interference, the up-and-coming field of general immune-signalling pathways, and cell death/apoptosis.
Summary Sera collected from 60 selected South Florida patients with undiagnosed infectious disease in 1961, 1962, and 1963 were studied in hemagglutination-inhibition tests with 22 selected arboviruses. This was done in order to determine whether or not any one of the viruses caused the disease of each patient and to determine the HI antibody status of representative South Florida residents against a spectrum of arboviruses. Among the 60 patients, 11 had encephalitis, 39 had aseptic meningitis, and the illnesses of the remaining 10 were characterized as undifferentiated febrile illnesses. Hemagglutination-inhibition antibodies were observed to 10 arboviruses in one or more of the late sera from nine patients: three were cases of encephalitis, three were aseptic meningitis and three were classified as undifferentiated febrile illnesses. The antibodies were to eight Group B viruses including bat salivary gland, Bussuquara, dengue type 2, Ilheus, Modoc, MVE, Powassan, and SLE, as well as Bunyamwera, Guaroa
Culicoides biting midges (Diptera: Ceratopogonidae) are currently the most important biological vectors of livestock arboviruses in Europe. Outbreaks of bluetongue virus (BTV) and Schmallenberg virus (SBV) continue to have a significant economic impact through clinical disease and the imposition of animal trade movement restrictions. At least three Culicoides-borne viruses recently identified in Europe possess an unknown origin, hence future outbreaks involving described or undescribed strains or species of Culicoides-borne viruses have a high potential of occurring in the future. These viruses could include further incursions of known arboviruses (including additional species of Culicoides-borne arboviruses such as African horse sickness or Epizootic Haemorhagic Disease Virus) or as yet undescribed species with an unknown pathogenicity to livestock or humans. In this project we will dissect Culicoides vector-arbovirus relationships across multiple ecosystems and species and in unprecedented ...
Abstract. White-tailed deer (Odocoileus virginianus) are an abundant mammal with a wide geographic distribution in the United States, which make them good sentinels for monitoring arboviral activity across the country. Exposure to various arboviruses has been detected in white-tailed deer, typically in conjunction with another diagnostic finding. To better assess the exposure of white-tailed deer to seven arboviruses, we tested 1,508 sera collected from 2010 to 2016 for antibodies to eastern equine encephalitis (2.5%), Powassan (4.2%), St. Louis encephalitis, (3.7%), West Nile (6.0%), Maguari (19.4%), La Crosse (30.3%), and bluetongue (7.8%) viruses. At least one arbovirus was detected in 51.3%, and exposure to more than one arbovirus was identified in 17.6% of the white-tailed deer sampled.
Arboviruses, or arthropod-borne viruses, affecting humans are RNA viruses that are biologically transmitted to vertebrate hosts by the bite of arthropod vectors. There are more than 500 arboviruses which are grouped in at least seven families; Togaviridae, Flaviviridae, Bunyaviridae, Reoviridae, Rhabdoviridae, Orthomyxoviridae, and Asfarviridae.. About 100 arboviruses cause illness in humans and through investigation of travel history and exposures laboratory and clinical diagnosis can be simplified. The majority of arboviruses result in simple febrile illness that is not uncommon to symptoms of common viral or bacterial infections. Typically clinical features of acute arboviral fevers usually include a sudden onset of debilitating symptoms, such as malaise, extreme headache, myalgia, lumbar pain, and sometimes nausea, vomiting, and dizziness (Lanciotti & Tsai, 2007, p. 1486). Given the large number of arboviruses there is a broad range of symptoms that may also occur including aseptic ...
The rapid succession of the pandemic of arbovirus diseases, such as dengue, West Nile fever, chikungunya, and Zika fever, has intensified research on these and other arbovirus diseases worldwide. Investigating the unique mode of vector-borne transmission requires a clear understanding of the roles of vertebrates. One major obstacle to this understanding is the ambiguity of the arbovirus definition originally established by the World Health Organization. The paucity of pertinent information on arbovirus transmission at the time contributed to the notion that vertebrates played the role of reservoir in the arbovirus transmission cycle. Because this notion is a salient feature of the arbovirus definition, it is important to reexamine its validity. This review addresses controversial issues concerning vertebrate reservoirs and their role in arbovirus persistence in nature, examines the genesis of the problem from a historical perspective, discusses various unresolved issues from multiple points of view,
Arbovirus is a term used to refer to any viruses that is transmitted by arthropod vectors. The word arbovirus is an acronym (ARthropod-BOrne virus). The word tibovirus (TIck-BOrne virus) is sometimes used to more specifically describe viruses transmitted by ticks, a superorder within the arthropods. Arboviruses can affect both animals, including humans, and plants. In humans, symptoms of arbovirus infection generally occur 3-15 days after exposure to the virus and last 3 or 4 days. The most common clinical features of infection are fever, headache, and malaise, but encephalitis and hemorrhagic fever may also occur. Arboviruses were not known to exist until the rise of modern medicine, with the germ theory and an understanding that viruses were distinct from other microorganisms. The connection between arthropods and disease was not postulated until 1881 when Cuban doctor and scientist Carlos Finlay proposed that yellow fever may be transmitted by mosquitoes instead of human contact, a reality ...
Arboviruses (arthropod-borne virus) cause viral infections that are spread by mosquitoes and other blood-sucking insects, such as ticks. Arbovirus testing can help diagnose the cause of meningitis or encephalitis and distinguish an arbovirus infection from other conditions causing similar symptoms.

BACKGROUND: Epidemic arbovirus transmission occurs among humans by mosquito bites and the sylvatic transmission cycles involving non-human primates (NHPs) still exists. However, limited data are available on the extent in NHPs infections and their role. In this study, we have developed and validated a high-throughput serological screening tool to study the circulation of multiple arboviruses that represent a significant threat to human health, in NHPs in Central Africa.METHODOLOGY/PRINCIPAL FINDINGS: Recombinant proteins NS1, envelope domain-3 (DIII) for the dengue (DENV), yellow fever (YFV), usutu (USUV), west nile (WNV) and zika (ZIKV) and envelope 2 for the chikungunya (CHIKV) and onyong-nyong (ONNV) were coupled to Luminex beads to detect IgG directed against these viruses. Evaluation of test performance was made using 161 human sera of known arboviral status (66 negative and 95 positive). The sensitivity and specificity of each antigen were determined by statistical methods and ROC curves ...

Diseases caused by arthropod-borne viruses (arboviruses), such as Dengue, West Nile, and Chikungunya, constitute a major global health burden and are increasing in incidence and geographic range. The natural microbiota of insect vectors influences various aspects of host biology, such as nutrition, reproduction, metabolism, and immunity, and recent studies have .
Background , Models of arbovirus transmission are useful in estimating the burden of Dengue, forecasting areas of risk for the emergence of Dengue, Chikungunya and Zika in non-endemic areas, and in assessing the potential of control interventions. The utility of these models relies on their grounding in empirical data at multiple scales describing the disease transmission process. The aims are to (i) model the dynamics of viruses in their invertebrate and vertebrate hosts as well as the movement of these hosts viz ...

The primary mode of transmission of arthropod-borne viruses is through the bite of an infected mosquito, where virus is injected into the host skin along with mosquito saliva. Although modulation of the host immune response by mosquito saliva alone or during viral infection has been studied, full evaluation of the complex dynamics between different viruses, mosquitoes, and the ecosystem is lacking. Specifically, the differential effects of variant combinations of vector and virus species on the modulation of the local (skin) and systemic immune response and outcome of pathogenesis in the vertebrate host has not yet been extensively studied. In addition, recent introduction of exotic mosquito species in the Netherlands, such as the Asian bush mosquito Aedes japonicus, warrants investigation of the ability of such mosquitoes to transmit emerging viruses to humans and cause disease. Therefore, examining the effect of a mosquito bite from different relevant mosquitoes under changing environmental ...

Background: The global distribution and disease burden of arboviral diseases have increased over recent years. In the Middle East and North Africa (MENA) region, the epidemiology of arboviruses remains poorly characterized. Methods: Following the PRISMA guidelines, we systematically reviewed available records across the WHO, World Bank, and UNAIDS-defined MENA region describing the human, animal, and vector prevalence for six arboviruses which were selected based on their known endemicity in the region and broader global importance: chikungunya virus (CHIKV), crimean-congo hemorrhagic fever virus (CCHFV), dengue virus (DENV), rift valley fever virus (RVFV), west nile virus (WNV), and yellow fever (YFV). Geospatial prevalence maps were generated using ArcGIS software. Results: We screened 2,090 reports and identified 586 prevalence measures for the arboviruses of interest in humans (40%) and animals (60%) in MENA. Countries with no published prevalence data were Algeria, Bahrain, Palestine, ...
Colorado tick fever (CTF) is a disease caused by an RNA virus, Colorado tick fever virus (CTFV). Symptoms, which are often non-specific, begin 3 to 5 days after the bite with an abrupt onset of fever and any of these: headaches, chills, malaise, photophobia, myalgias, nausea, vomiting, diarrhea and abdominal pain. In 5 to 15% of cases a rash occurs. Neurologic complications may also occur. 50% of patients have single recurrence of fever (saddleback fever).. IFA titers for diagnosis. PCR (Polymerase Chain Reaction) is the test most often used to diagnose the disease. CTF is transmitted by Dermacentor andersoni (Rocky Mt. wood tick) which causes illness from the Western Black Hills to the West Coast in the USA. Some cases of transmission through blood transfusion have been reported. Treatment consists of supportive care.. ©LDA. 2014. 2015.

In nature, infected and uninfected arthropod vectors often feed together on an animal. In mimicking this scenario in the laboratory, uninfected vectors were found to acquire virus while cofeeding on the same host as infected vectors. However, the vertebrate host on which they fed did not develop detectable levels of virus in its blood. These observations were made with Thogoto virus, an influenza-like virus of medical and veterinary significance. Rhipicephalus appendiculatus ticks were used as the vector and guinea pigs as the vertebrate host. The results demonstrate that a vertebrate that is apparently refractory to infection by an arthropod-borne virus can still play an important role in the epidemiology of the virus, and they suggest a novel mode of arthropod-borne virus transmission.

The Alphavirus genus within the Togaviridae family contains several important mosquito-borne arboviruses. Other than the antiviral activity of RNAi, relatively little is known about alphavirus interactions with insect cell defences. Here we show that Semliki Forest virus (SFV) infection of Aedes albopictus-derived U4.4 mosquito cells reduces cellular gene expression. Activation prior to SFV infection of pathways involving STAT/IMD, but not Toll signaling reduced subsequent virus gene expression and RNA levels. These pathways are therefore not only able to mediate protective responses against bacteria but also arboviruses. However, SFV infection of mosquito cells did not result in activation of any of these pathways and suppressed their subsequent activation by other stimuli. ...
All the Dogs owners asked this common question as to how can we identify the Dog Tick Fever? No worries, we will help you. If a dog has tick fever which appears in acute, sub-clinical and chronic stages. Acute will experience symptoms such as respiratory troubles, swollen lymph nodes, loss of weight, fever, bleeding problems, and neurological issues. It appears in the beginning stages of tick fever. In fact, sub-clinical stage of Dog Tick Fever, display zero indication of the disease. So that dont exhibit symptoms and the dog possesses a good immune system, they could potentially fight off tick fever during the sub-clinical period. In the chronic stages, they might display severe symptoms such as anemia, vision difficulties, eye hemorrhaging is one example and lameness, uncontrollable bleeding, limb swelling, and failure of the bone marrow. Then their health condition characterized by low blood-platelet counts. So that chronic ehrlichiosis sometimes succumbs to the ailment.. Beyond that, After ...

Despite the use of insecticides and other measures of vector control, arboviral diseases are on the rise. One potential solution for limiting disease transmission to humans is to render mosquitoes refractory to viral infection through genetic modification. Substantial research effort in Drosophila, Aedes and Anopheles has helped to define the major innate immune pathways, including Toll, IMD, Jak/Stat and RNAi, however we still have an incomplete picture of the mosquito antiviral response.

Arthropod-transmitted viruses, known as arboviruses, can cause pandemic diseases in humans, animals, and crops. The Zika virus and cassava geminivirus are two such arboviruses. These pathogens often alter host characteristics to directly or indirectly influence arthropod vector behaviors or host-herbivore interactions, thus facilitating disease transmission.. Pathogen-infected hosts may promote the performance of vector insects; but whether and how pathogens affect nonvector insects have been largely unexplored.. In a study published online in Science Advances, a group of scientists led by Prof. Ye Jian from the Institute of Microbiology of the Chinese Academy of Sciences discovered that viruses mobilize plant immunity to deter nonvector insect herbivores. They uncovered the mechanism used by begomoviruses (the largest genus of plant viruses in the world) to alter a host plants immune system. This discovery may facilitate the development of biological methods to control vector-borne ...
We found this interesting information on the internet and thought you would like to be aware of the symptoms of Zika…especially since its so new here in the US.. Symptoms of Zika virus in most people are similar to other arboviruses such as Chikungunya (fever, headache, fatigue primarily). The recent epidemic in Brazil, however, has been distinctively marked by detection of the disease in fetal amniotic fluid and an elevated reporting of cases of microcephaly (small head size) in newborns.. Given the virus recent introduction to the Americas, some epidemiologists have expressed concern that resistance may be low, leading to increased transmission rates and severity of symptoms. In rare cases, Zika symptoms have been associated with Guillain-Barre syndrome, which causes the bodys immune system to attack its neurological system and can lead to paralysis.. Because no Zika vaccine yet exist, the response to the outbreak involves stepped-up public health efforts, including vector control of ...

Mosquitoes are small, midge-like flies, which comprise the family Culicidae. Females of most species are ectoparasites, whose tube-like mouthparts (called a proboscis) pierce the hosts skin to consume blood. The word mosquito (formed by mosca and diminutive ito) is Spanish for little fly.[2] Thousands of species feed on the blood of various kinds of hosts, mainly vertebrates, including mammals, birds, reptiles, amphibians, and even some kinds of fish. Some mosquitoes also attack invertebrates, mainly arthropods. Though the loss of blood is seldom of any importance to the victim, the saliva of the mosquito often causes an irritating rash that is a serious nuisance. Much more serious though, are the roles of many species of mosquitoes as vectors of diseases. In passing from host to host, some transmit extremely harmful infections such as malaria, yellow fever, Chikungunya, west Nile virus, dengue fever, filariasis, Zika virus and other arboviruses, rendering it the deadliest animal family in ...

State of Connecticut Mosquito Trapping and Arbovirus Testing Program--Historical Information Abstract: State of Connecticut Mosquito Trapping and Arbovirus Testing Program--Historical Information--1993-2013
Unlike most arboviruses that replicate in the cytoplasm of the host cells, ZIKAV replicates in the nucleus. ZIKAV is an enveloped virus with a positive sense, single stranded, 11 kb RNA genome. It contains 5 and 3 untranslated regions flanking a single open reading frame. The single polypeptide is cleaved by cellular and viral proteases into three structural proteins, the binding capsid, and seven non-structural proteins. Infection begins in dendritic cells at the site of inoculation, and spreads to lymph nodes and the bloodstream throughout the host. At present, ZIKAV viral RNA concentrations are detectable in blood specimens collected ,3 days after the onset of illness, and levels are still detectable in some individuals as late as 11 days after illness onset [2].. ZIKAV manifests clinically with headache, rash, fever, joint pain, and malaise; the symptomology resembles that of Dengue, Yellow Fever, West Nile, and Chikungunya viruses. However, it is estimated that only 1 in 4 infected ...
