Mechanisms of arthropod transmission of plant and animal viruses. (1/145)

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)

Restriction of major surface protein 2 (MSP2) variants during tick transmission of the ehrlichia Anaplasma marginale. (2/145)

Anaplasma marginale is an ehrlichial pathogen of cattle that establishes lifelong persistent infection. Persistence is characterized by rickettsemic cycles in which new A. marginale variant types, defined by the sequence of the expressed msp2 transcripts, emerge. The polymorphic msp2 transcripts encode structurally distinct MSP2 proteins and result in an antigenically diverse and continually changing A. marginale population within the blood. In this manuscript, we used sequence analysis of msp2 transcripts to show that a restricted repertoire of variant types, designated SGV1 and SGV2, is expressed within the tick salivary gland. The same SGV1 and SGV2 variant types were expressed in ticks regardless of the variant types expressed in the blood of infected cattle at the time of acquisition feeding by the ticks. Importantly, subsequent tick transmission to susceptible cattle resulted in acute rickettsemia composed of organisms expressing only the same SGV1 and SGV2 variant types. This indicates that the msp2 expressed by organisms within the tick salivary gland predicts the variant type responsible for acute rickettsemia and disease. This restriction of transmitted A. marginale variant types, in contrast to the marked diversity within persistently infected cattle, supports development of MSP2 vaccines to prevent acute rickettsemia in tick-transmitted infections.  (+info)

Observations on the epidemiology of Rift Valley fever in Kenya. (3/145)

The epizootic range of Rift Valley fever in Kenya is defined from the results of virus isolations during epizootics, and form an extensive serological survey of cattle which were exposed during an epizootic. A study of the sera from a wide range of wild bovidae sampled immediately after the epizootic, showed that they did not act as reservoir or amplifying hosts for RVF. Virus isolation attempts from a variety of rodents proved negative. Rift Valley fever did not persist between epizootics by producing symptomless abortions in cattle in areas within its epizootic range. A sentinel herd sampled annually after an epizootic in 1968 revealed not one single seroconversion from 1969 to 1974. Certain forest and forest edge situations were postulated as enzootic for Rift Valley fever, and a small percentage of seroconversions were detected in cattle in these areas, born four years after the last epizootic. This has been the only evidence for the persistence of the virus in Kenya since 1968, and may be a part of the interepizootic maintenance cycle for Rift Valley fever in Kenya, which otherwise remains unknown.  (+info)

The differential transmissibility of Myxoma virus strains of differing virulence grades by the rabbit flea Spilopsyllus cuniculi (Dale). (4/145)

Laboratory studies showed that few rabbit fleas (Spilopsyllus cuniculi (Dale)) transmitted myxomatosis after removal from wild rabbits (Oryctolagus cuniculus (L) that had been infected for fever than 10-12 days, irrespective of the virulence of the myxoma virus strain involved. Rabbits infected with fully virulent (Grade I) strains died within 10-15 days and few fleas from these hosts became infective; averaging all the samples takem. 12% of the fleas were infective. Also, few fleas acquired infectivity on individual rabbits which covered from infection with attenuated strains; the mean was 8% infective. Rabbits which died between 17 and 44 days after infection had higher proportions of infective fleas at all sampling times; the mean was 42% infective. Male and female fleas transmitted virus with equal efficiency. For rabbits infected with any of the attenuated virus strains the mean percentage of infective fleas was inversely related to the survival time of the host. Rabbits infected with moderately attenuated strains (Grades IIIA and IIIB) had, on average, the highest proportion of infective fleas; hence such strains have a selective advantage and have become predominant under natural conditions in Britain. The changes that might occur if there is an increase in host resistance to myxomatosis are discussed.  (+info)

Anti-arthropod saliva antibodies among residents of a community at high risk for Lyme disease in California. (5/145)

The role of the western black-legged tick (Ixodes pacificus) versus that of other potential arthropod vectors in the epidemiology of Lyme disease was evaluated by determining the prevalence of anti-arthropod saliva antibodies (AASA) among residents (n = 104) of a community at high-risk (CHR). Salivary gland extracts prepared from I. pacificus, the Pacific Coast tick (Dermacentor occidentalis), the western cone-nose bug (Triatoma protracta), and the western tree-hole mosquito (Aedes sierrensis) were used as antigens in an ELISA. Sera from 50 residents of the San Francisco Bay region in northern California and 51 residents of Imperial County in southern California served as comparison groups. The prevalence of AASA ranged from 2% for A. sierrensis to 79% for I. pacificus in study subjects, 0% for D. occidentalis to 36% for I. pacificus among residents of the San Francisco Bay region, and 6% for I. pacificus to 24% for A. sierrensis in residents of Imperial County. The associations between AASA and demographic factors, potential risk factors, probable Lyme disease, and seropositivity for Borrelia burgdorferi were assessed for 85 members of the CHR. Seropositivity for I. pacificus and B. burgdorferi were significantly correlated, the relative risk of seropositivity to B. burgdorferi was about 5 (31% versus 6%) for subjects who were seroreactive to I. pacificus, nearly every individual who was seropositive for B. burgdorferi had elevated levels of antibodies to I. pacificus, and the mean titer for antibodies to I. pacificus was significantly higher for subjects seropositive versus those seronegative for B. burgdorferi. Together, these findings support the widely held belief that I. pacificus is the primary vector of B. burgdorferi for humans in northern California, and they demonstrate the utility of the AASA method as an epidemiologic tool for studying emerging tick-borne infections.  (+info)

Temporal changes in outer surface proteins A and C of the lyme disease-associated spirochete, Borrelia burgdorferi, during the chain of infection in ticks and mice. (6/145)

The Lyme disease-associated spirochete, Borrelia burgdorferi, is maintained in enzootic cycles involving Ixodes ticks and small mammals. Previous studies demonstrated that B. burgdorferi expresses outer surface protein A (OspA) but not OspC when residing in the midgut of unfed ticks. However, after ticks feed on blood, some spirochetes stop making OspA and express OspC. Our current work examined the timing and frequency of OspA and OspC expression by B. burgdorferi in infected Ixodes scapularis nymphs as they fed on uninfected mice and in uninfected I. scapularis larvae and nymphs as they first acquired spirochetes from infected mice. Smears of midguts from previously infected ticks were prepared at 12- or 24-h intervals following attachment through repletion at 96 h, and spirochetes were stained for immunofluorescence for detection of antibodies to OspA and OspC. As shown previously, prior to feeding spirochetes in nymphs expressed OspA but not OspC. During nymphal feeding, however, the proportion of spirochetes expressing OspA decreased, while spirochetes expressing OspC became detectable. In fact, spirochetes rapidly began to express OspC, with the greatest proportion of spirochetes having this protein at 48 h of attachment and then with the proportion decreasing significantly by the time that the ticks had completed feeding. In vitro cultivation of the spirochete at different temperatures showed OspC to be most abundant when the spirochetes were grown at 37 degrees C. Yet, the synthesis of this protein waned with continuous passage at this temperature. Immunofluorescence staining of spirochetes in smears of midguts from larvae and nymphs still attached or having completed feeding on infected mice demonstrated that OspA but not OspC was produced by these spirochetes recently acquired from mice. Therefore, the temporal synthesis of OspC by spirochetes only in feeding ticks that were infected prior to the blood meal suggests that this surface protein is involved in transmission from tick to mammal but not from mammal to tick.  (+info)

Phylogeny of the genus flavivirus using complete coding sequences of arthropod-borne viruses and viruses with no known vector. (7/145)

Attempts to define the evolutionary relationships and origins of viruses in the genus Flavivirus are hampered by the lack of genetic information particularly amongst the non-vectored flaviviruses. Using a novel protocol for sequence determination, the first complete coding sequence of St Louis encephalitis virus and those of two representative non-vectored flaviviruses, Rio Bravo (isolated from bat) and Apoi (isolated from rodent), are reported. The encoded polyproteins of Rio Bravo and Apoi virus are the smallest described to date within the genus FLAVIVIRUS: The highest similarities with other flaviviruses were found in the NS3 and NS5 genes. The proteolytic cleavage sites for the viral serine protease were highly conserved among the flaviviruses completely sequenced to date. Comparative genetic amino acid alignments revealed that p-distance cut-off values of 0.330-0.470 distinguished the arthropod-borne viruses according to their recognized serogroups and Rio Bravo and Apoi virus were assigned to two distinct non-vectored virus groups. Within these serogroups, cladogenesis based on the complete ORF sequence was similar to trees based on envelope and NS5 sequences. In contrast, branching patterns at the deeper nodes of the tree were different from those reported in the previous study of NS5 sequences. The significance of these observations is discussed.  (+info)

Genetics of mosquito vector competence. (8/145)

Mosquito-borne diseases are responsible for significant human morbidity and mortality throughout the world. Efforts to control mosquito-borne diseases have been impeded, in part, by the development of drug-resistant parasites, insecticide-resistant mosquitoes, and environmental concerns over the application of insecticides. Therefore, there is a need to develop novel disease control strategies that can complement or replace existing control methods. One such strategy is to generate pathogen-resistant mosquitoes from those that are susceptible. To this end, efforts have focused on isolating and characterizing genes that influence mosquito vector competence. It has been known for over 70 years that there is a genetic basis for the susceptibility of mosquitoes to parasites, but until the advent of powerful molecular biological tools and protocols, it was difficult to assess the interactions of pathogens with their host tissues within the mosquito at a molecular level. Moreover, it has been only recently that the molecular mechanisms responsible for pathogen destruction, such as melanotic encapsulation and immune peptide production, have been investigated. The molecular characterization of genes that influence vector competence is becoming routine, and with the development of the Sindbis virus transducing system, potential antipathogen genes now can be introduced into the mosquito and their effect on parasite development can be assessed in vivo. With the recent successes in the field of mosquito germ line transformation, it seems likely that the generation of a pathogen-resistant mosquito population from a susceptible population soon will become a reality.  (+info)

Rickettsial diseases, important causes of illness and death worldwide, exist primarily in endemic and enzootic foci that occasionally give rise to sporadic or seasonal outbreaks. Rickettsial pathogens are highly specialized for obligate intracellular survival in both the vertebrate host and the invertebrate vector. While studies often focus primarily on the vertebrate host, the arthropod vector is often more important in the natural maintenance of the pathogen. Consequently, coevolution of rickettsiae with arthropods is responsible for many features of the host-pathogen relationship that are unique among arthropod-borne diseases, including efficient pathogen replication, long-term maintenance of infection, and transstadial and transovarial transmission. This article examines the common features of the host-pathogen relationship and of the arthropod vectors of the typhus and spotted fever group rickettsiae.

Bacterial symbionts may be used as vehicles for expressing foreign genes in arthropods. Expression of selected genes can render an arthropod incapable of transmitting a second microorganism that is pathogenic for humans and is an alternative approach to the control of arthropod-borne diseases. We discuss the rationale for this alternative approach, its potential applications and limitations, and the regulatory concerns that may arise from its use in interrupting disease transmission in humans and animals.
Bartonella species are Gram-negative bacilli or coccobacilli belonging to the α2 subgroup of Proteobacteria that are closely related to the genera Brucella and Agrobacterium. Each persists in particular mammalian hosts, with transmission to humans primarily mediated by haematophagous arthropods. A remarkable feature of the genus ...
arborvirus: a large heterogeneous group of RNA viruses divisible into groups on the basis of the virions; they have been recovered from arthropods, bats, and rodents; most are borne by arthropods; they are linked by the epidemiologic concept of transmission between vertebrate hosts by arthropod vectors (mosquitoes, ticks, sandflies, midges, etc.) that feed on blood; they can cause mild fevers, hepatitis, hemorrhagic fever, and encephalitis
Protozoa are microscopic, one-celled organisms that can be free-living or parasitic in nature. They are able to multiply in humans, which contributes to their survival and also permits serious infections to develop from just a single organism. Transmission of protozoa that live in a humans intestine to another human typically occurs through a fecal-oral route (for example, contaminated food or water or person-to-person contact). Protozoa that live in the blood or tissue of humans are transmitted to other humans by an arthropod vector (for example, through the bite of a mosquito or sand fly ...

Transovarial or transovarian transmission occurs in certain arthropod vectors as they transmit disease-causing pathogens from parent arthropod to offspring arthropod. For instance, Rickettsia rickettsii, carried within ticks, is passed on from parent to offspring tick by transovarial transmission. In contrast, Rickettsia prowazekii is not passed on by transovarian transmission because it kills the vector that carries it (human louse). This is the mechanism by which many Rickettsiae are maintained in their arthropod hosts through generations, which occurs also in aedes mosquito vector of the yellow fever virus and in phlebotomine sandflies that transmit pappataci fever. Richard Dawkins in "The Extended Phenotype" page 222 (1999 edition) notes that "bacterial endosymbionts of insects which are transmitted transovarially" share an interest in the "success of their hosts gametes.....as well as the survival of their hosts body." In this case, "the interest of the host genes and parasite genes might ...
Hildebrand will speak on "The most dangerous animals in the world: Arthropod vectors of disease" in the Price Auditorium, of the John Gray Center, Herman Iles Building at 7:30 p.m. Hildebrand will meet with LU medical pre-professional students at 3 p.m. in Hayes Biology, Room 200. This meeting is also open to the public.. Diseases caused by pathogens (viruses, bacteria, and parasites) that are transmitted to hosts by arthropod vectors (for example, blood-sucking insects and ticks) collectively are the most important infectious diseases of humans. For many of these diseases, the vector arthropods are essential for transmission of the pathogen to a human host, and some of them are diabolically effective in fulfilling that mission. This lecture will survey biological, medical, and societal aspects of selected vector-borne diseases, with particular attention to the vector arthropods that transmit the pathogens.. Malaria, Zika, West Nile, Rocky Mountain Spotted Fever, Lymes Disease, Chagas and other ...
Bartonella quintana (BQ) is a gram-negative human pathogen that causes serious and potentially fatal infections, and is the leading cause of culture-negative heart valve infection in the US. BQ also causes persistent bacteremia and fatal illness in immunocompromised individuals with cancer and HIV/AIDS. BQ is transmitted to humans by the body louse; humans become infected when the BQ bacteria in the louse feces are introduced into the louse bite wound by scratching. BQ alternates between two very different niches: the bloodstream of the homeothermic mammalian reservoir (37C) and the gut of the poikilothermic arthropod vector (28C). Virtually nothing is known about the virulence factors involved in the transition between the host and arthropod vector. However, the arthropod niche is an essential part of the life cycle of BQ, and it is required for infection of humans. To surviv and proliferate, BQ bacteria must adapt rapidly during the shift between these two disparate environments. Such ...

Mammals provide the primary reservoir for F tularensis, including ground squirrels, rabbits, hares, voles, muskrats, water rats, and other rodents. Human infection typically occurs after handling infected animals or after a bite from an arthropod vector. In the United States, biting flies and ticks are the primary arthropod vectors. In Europe and the former Soviet Union, ticks and mosquitoes have been reported to transmit infection. Infection can also occur after ingestion of contaminated food or water or after inhalation of the organism from decaying animal carcasses, contaminated straw, or other sources. There have been several large waterborne outbreaks of tularemia in Europe and the former Soviet Union. The largest airborne outbreak of tularemia was reported among farmers in Sweden in the 1960s, attributed to the aerosolization of organisms from rodent-infested hay. There has been no documented person-to-person transmission of tularemia. ...

Dr. Elliot Krafsurs main research interests were evolutionary biology, insect genetics, insect demography, and the epidemiology of arthropod-borne diseases. Some of his research also focused on population ecology and genetics of various medially important flies, including the tsetse fly.
The Australian paralysis tick (Ixodes holocyclus) is of significant medical and veterinary importance as a cause of dermatological and neurological disease, yet there is currently limited information about the bacterial communities harboured by these ticks and the risk of infectious disease transmission to humans and domestic animals. Ongoing controversy about the presence of Borrelia burgdorferi sensu lato (the aetiological agent of Lyme disease) in Australia increases the need to accurately identify and characterise bacteria harboured by I. holocyclus ticks. Universal PCR primers were used to amplify the V1-2 hyper-variable region of bacterial 16S rRNA genes present in DNA samples from I. holocyclus and I. ricinus ticks, collected in Australia and Germany respectively. The 16S amplicons were purified, sequenced on the Ion Torrent platform, and analysed in USEARCH, QIIME, and BLAST to assign genus and species-level taxonomy. Initial analysis of I. holocyclus and I. ricinus identified that | 95 % of the
Rapid and reliable identification of the vertebrate species on which a disease vector previously parasitized is imperative to study ecological factors that affect pathogen distribution and can aid the development of public health programs. Here we describe a proteome profiling technique designed to identify the source of blood meals of haematophagous arthropods. This method employs direct spectral matching and thus does not require a priori knowledge of any genetic or protein sequence information. Using this technology, we detect remnants of blood in blacklegged ticks (Ixodes scapularis) and correctly determine the vertebrate species from which the blood was derived, even 6 months after the tick had fed. This biological fingerprinting methodology is sensitive, fast, cost-effective and can potentially be adapted for other biological and medical applications when existing genome-based methods are impractical or ineffective ...
I just happended on this item while staying up late researching. I am an Urban Forester in another state, city about the size of yours. Before I started this position the city had no forester, no urban forest plan, no real involvement in the urban forest. My first plan of action, as is most when comming into a community was Hazard Tree Identification. The city had spent, on average about $212,000.00 each year settling claims (some death related) on litigation over tree hazards. I know of Mr. Passmore, do not know him personally, but by reputation only. You have a great man with a passion for his work and if you review the cost associated with NOT having an Urban Forester you might be suprised. I wish him all the luck in the world.. ...

In the December 2017 VectorBase release VectorBase announced the adoption of the new Aedes aegypti AaegL5 genome assembly produced by the Aedes aegypti Genome Working group. We have received a number of communications from the community that indicate people are encountering significant problems when working with the new gene set based on this assembly. The NCBI Aedes aegypti annotation release 101 (https://www.ncbi.nlm.nih.gov/genome/annotation_euk/Aedes_aegypti/101/) was a new de novo annotation using the Gnomon software (https://www.ncbi.nlm.nih.gov/genome/annotation_euk/gnomon/), and as such differs significantly from the existing AaegL3 gene set. VectorBase has worked with the NCBI to attempt to map existing stable gene ids between the assemblies, but given the nature of the different assembly and predicted gene models this has not always been possible. Improved contiguation of the AaegL5 assembly has resulted in significant gene model changes at a number of loci as a result of split/merge ...

Today I shared a website with my kids on arthropods. Warning: it takes evolution as fact clear back to the idea that all things came from one or two animals, but it also has a great illustration of what makes an arthropod an arthropod. The two parts are separate so you dont have to go to the evolutionary part. The link I gave starts at the "What is an arthropod?" section. The evolution part precedes it. I believe in a creator, and I believe he guided the process very carefully but since he hasnt filled in the details himself, Im not going say he couldnt have used evolution when it was appropriate. However, the idea that everything came from one or two animals is ludicrous in my opinion. Especially given the command he gave to the animals to multiply and replenish the earth after their own kind. Cross two dogs of different breeds and you get a . . . dog. Not something else. If you cross a lab with a collie, you will get . . . a mutt. Cross enough mutts, and another breed of dog will emerge. ...

7 hardy foresters took on the Mynydd Llangorse/Grim Reaper Fell Race, based at the Llangorse Rope centre. Murky looking clouds were covering the mountains travelling to the race, but luckily this had lifted, making excellent running conditions, in time for the race. The 3 mile race started with a slog up through some muddy fields, then flattened out for a while, traversing the side of the hill, before cutting back right, and steeply ascending to the trig point. From the trig, it was all downhill, as fast as you dared, down another muddy path, through a stream and back to the start/finish field for a final sprint across the line.

HEELS ON WHEELS: 2009 SUBARU FORESTER REVIEW HEELS ON WHEELS By Katrina Ramser San Francisco Bureau The Auto Channel INTRO TO THE FORESTER VEHICLE The Forester dropped its nerdy look and adapted an SUV sex appeal that seems to work for both consumers and automotive media alike. The 2009 Forester has the honor of being awarded Motor Trends 2009 Sport/Utility Car of the Year and also became Consumer Reports top-rated small SUV, beating out competitors like the tougher looking Toyota RAV4 and the sleek, redesigned Honda CR-V. I drove a 2009 Forester with the 170-horsepower, 2.5-liter 4-cylindar Pzec (Partial Zero Emissions) engine ($451), 4-speed auto transmission with Sport Shift ($1,000) and Subarus standard symmetrical all-wheel drive. Highlights from the premium package that came standard with my model included a large, power moonroof; roof rails; rear seat retractable cup tray; all-season 17-inch tires; and steering wheel mounted controls.

Rift Valley Fever (RVF) is an arthropod-borne disease endemic to much of Sub-Saharan Africa and the Arabian Peninsula causing abortion storms and high neonatal mortality in sheep, goats, and cattle and influenza-like to hemorrhagic illness in humans. RVF is transmitted by over 30 species of arthropods and can persist in the soil for decades in the trans-ovarially infected, desiccation resistant eggs of Aedine species of mosquitoes. Recent increases in the severity and frequency of RVF outbreaks within East Africa in addition to concern for the potential for RVF spread to new areas has prompted interest by several public health authorities in improving disease forecasting tools. This report describes factors of RVF ecology and epidemiology important to current disease forecasting efforts and gives recommendations for the spatial and temporal refinement of extant modelling efforts ...
Mosquito blood meals provide information about the feeding habits and host preference of potential arthropod-borne disease vectors. Although mosquito-borne diseases are ubiquitous in the Neotropics, few studies in this region have assessed patterns of mosquito-host interactions, especially during actual disease outbreaks. Based on collections made during and after an outbreak of equine viral encephalitis, we identified the source of 338 blood meals from 10 species of mosquitoes from Aruza Abajo, a location in Darien province in eastern Panama. A PCR based method targeting three distinct mitochondrial targets and subsequent DNA sequencing was used in an effort to delineate vector-host relationships. At Aruza Abajo, large domesticated mammals dominated the assemblage of mosquito blood meals while wild bird and mammal species represented only a small portion of the blood meal pool. Most mosquito species fed on a variety of hosts; foraging index analysis indicates that eight of nine mosquito species ...
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 ...
Vector-borne diseases are an increasing global threat to humans due to climate changes, elevating the risk of infections transmitted by mosquitos, ticks, and other arthropod vectors. Ixodes ricinus, a common tick in Europe, transmits dangerous tick-borne pathogens to humans. Tick-borne encephalitis (TBE) is a vector-borne disease caused by TBE virus (TBEV). Climate change has contributed to increased tick abundance and incidence of tick-borne diseases, and between 10,000 and 15,000 human TBE cases are reported annually in Europe and Asia. TBEV shows a patchy geographical distribution pattern where each patch represents a natural focus. In nature, TBEV is maintained within the tick-rodent enzootic cycle. Co-feeding is the main route for TBEV transmission from infected to uninfected ticks and for maintenance within the natural foci. The increasing number of TBE cases in Scandinavia highlights the importance of characterizing additional TBEV sequences and of identifying novel natural foci, and in ...
Austin Journal of Vector Borne Diseases: Open Access is an open access, peer reviewed, scholarly journal dedicated to publish articles in all areas of vector borne diseases including existing or new policy in the relevant areas, impact of all types of vector borne diseases and related medical research methodologies. Vector-borne diseases are the infections transmitted by the bite of infected arthropod species, such as mosquitoes, ticks, triatomine bugs, sandflies, and blackflies. Arthropod vectors are cold-blooded (ectothermic) and thus especially sensitive to climatic factors. Or Vectors are organisms that transmit pathogens and parasites from one infected person (or animal) to another, causing serious diseases in human populations. These diseases are commonly found in tropical and sub-tropical regions and places where access to safe drinking-water and sanitation systems is problematic.

The "Four Fs of Infectious Disease": Fingers - improper handwashing or failure to wash hands regularly is one of the most commonly avoidable ways to prevent the spread of infectious disease. Fomites - any inanimate object a microbe can inhabit on a transient basis that can come in contact with a person, such as table and countertops, cups, dishes, towels, sponges, improperly sterilized laboratory or surgical equipment, gloves, doorknobs, drinking fountains or toilet seats. "Flies" - a general term describing arthropod vectors of disease. Diseases are spread either mechanically as microbes are picked up on the body surface and carried elsewhere or biologically when the arthropod takes a blood meal from an infected reservoir, then spreads the pathogen to new hosts when it takes new blood meals. Feces - human and animal wastes harbor large microbial populations, many of which could be pathogenic or act as opportunistic pathogens when spread to food and water owing to improper sanitary techniques ...

Some of the most devastating pathogens known to man, such as Yersinia pestis - responsible for the black plague - and Plasmodium falciparum, the causal agent of malaria, are obligately associated with invertebrate vectors (the flea and the mosquito respectively in this case). For a great deal of pathogen evolution, invertebrates were the only animal hosts available and this lifestyle will have significantly shaped/driven evolution of their respective pathogens. Upon the emergence of higher organisms, in particular warm-blooded animals, there would have been selection pressure to fill this new niche, but the exact extent and details of the types of adaptations that were required are still unclear.. Organisms capable of jumping the species barrier are of particular clinical importance, and understanding the mechanisms by which they do so has been an intense focus of at least the last 20-30 years - this is epitomised by the vast media attention which the likes of avian influenza and the Human ...
Capture-recapture (CR; e.g. [28, 29]) methods, including spatial capture-recapture (SCR; e.g., [60-63]), make use of individual-level detection data to estimate individual detection probability in order to obtain unbiased estimates of abundance or density. When used on temporally repeated datasets, capture-recapture data can further be used to investigate population dynamics (e.g. [64]). We focus this discussion on the assumptions and data requirements of single-season (i.e., closed population) SCR models, because these constitute an improvement over traditional closed population methods, specifically when it comes to surveying rare and wide ranging species (e.g. [65]). By making use of spatial information associated with individual detections, these models are able to account for variation in individual exposure to the sampling array, as well as animal movement. Key assumptions of SCR models that need careful consideration when using leeches as a sampling tool include independence of detections ...

In addition to their roles as vectors of infectious agents, the diverse group of animals that comprise arthropods may indirectly or directly cause injury that requires diagnosis and treatment. Such injuries include itching, dermal necrosis, anaphylaxis, and systemic toxicosis. The ubiquity of arthropods implies that they may be a frequent cause for clinical attention; reducing exposure is often sufficient to prevent or treat disease.

Author Summary Bubonic plague cycles depend on the ability of Yersinia pestis to alternately infect two very different hosts-a mammal and a flea. Like any arthropod-borne pathogen, Y. pestis must sense host-specific environmental cues and regulate gene expression accordingly to produce a transmissible infection in the flea after being taken up in a blood meal, and again when it exits the flea and enters the mammal. We examined the Y. pestis phenotype at the point of transmission by in vivo gene expression analyses, the first description of the transcriptome of an arthropod-borne bacterium in its vector. In addition to genes associated with physiological adaptation to the flea gut, several Y. pestis virulence factors required for resistance to innate immunity and dissemination in the mammal were induced in the flea, suggesting that the arthropod life stage primes Y. pestis for successful infection of the mammal.
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 ...
Rapid and accurate retrieval of whole genome sequences of human pathogens from disease vectors or animal reservoirs will enable fine-resolution studies of pathogen epidemiological and evolutionary dynamics. However, next generation sequencing technologies have not yet been fully harnessed for the study of vector-borne and zoonotic pathogens, due to the difficulty of obtaining high-quality pathogen sequence data directly from field specimens with a high ratio of host to pathogen DNA. We addressed this challenge by using custom probes for multiplexed hybrid capture to enrich for and sequence 30 Borrelia burgdorferi genomes from field samples of its arthropod vector. Hybrid capture enabled sequencing of nearly the complete genome (~99.5 %) of the Borrelia burgdorferi pathogen with 132-fold coverage, and identification of up to 12,291 single nucleotide polymorphisms per genome. The proprosed culture-independent method enables efficient whole genome capture and sequencing of pathogens directly from arthropod
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 vectors transmit organisms that cause many emerging and reemerging diseases, and their control is reliant mainly on the use of chemical insecticides. Only a few classes of insecticides are available for public health use, and the increased spread of insecticide resistance is a major threat to sustainable disease control. The primary strategy for mitigating the detrimental effects of insecticide resistance is the development of an insecticide resistance management plan. However, few examples exist to show how to implement such plans programmatically. We describe the formulation and implementation of a resistance management plan for mosquito vectors of human disease in Zambia. We also discuss challenges, steps taken to address the challenges, and directions for the future ...
Tularemia, also known as rabbit fever, is a zoonosis caused by the facultative intracellular, gram-negative bacterium Francisella tularensis. Infection occurs through contact with infected animals (often hares), arthropod vectors (such as ticks or deer flies), inhalation of contaminated dust or through contaminated food and water. In this review, we would like to provide an overview of the current epidemiological situation in Germany using published studies and case reports, an analysis of recent surveillance data and our own experience from the laboratory diagnostics and investigation of cases. While in Germany tularemia is a rarely reported disease, there is evidence of recent re-emergence. We also describe some peculiarities that were observed in Germany, such as a broad genetic diversity and a recently discovered new genus of Francisella and protracted or severe clinical courses of infections with the subspecies holarctica. Because tularemia is a zoonosis, we also touch upon the situation in the

Coxiella burnetii is the etiological agent of the worldwide distributed zoonosis Q fever. This review gives a comprehensive overview about the etiological agent and epidemiology of C. burnetii. Moreover, the role of arthropod vectors in transmission of C. burnetii is discussed. Detailed information is provided about current diagnostics and vaccination and importantly the most recent developments for improving the respective measures in animals. Immunoproteomic approaches are presented aimed to replace currently used whole cell antigen with well-defined and reproducible epitopes. Ruminants are considered as the main reservoir for human infections. The often subclinical infection in animals and suboptimal sensitivity of diagnostics hamper the identification of infected animals, while effectiveness of the current vaccine is questionable. New strategies based on advanced diagnostics and vaccines in animals will have the potential to prevent Q fever spreading and transmission to humans.

January 3, 2008 I entered the Beebe Medical Center with an unbearable pain in my right side. Later it was discovered I was passing a kidney stone. Believe me, if you havent passed a kidney stone, this is something you dont want to do.

For years, vector-borne zoonotic infectious diseases have had profound debilitating effects on humans. It has recently been revealed that several arthropod vectors including mosquitoes act as "bridge" vectors by transmitting pathogens from animals to humans and vice versa [1]. Human clinical cases of diseases, such as dirofilariasis, babesiosis, and leishmaniases, all caused by parasites transmitted by arthropod vectors from animals, have been reported to be on the rise [2-6]. Infection with these diseases have affects not only on humans but also on domestic and wild animals that can serve as potential reservoirs by hosting pathogens long-term despite being asymptomatic. Because eradication of animal reservoirs has been ethically rejected, surveillance and control of arthropod vectors must be central to programs aimed at elimination of vector-borne zoonotic diseases [5].. Dirofilaria species, including D. immitis and D. repens, are particularly important pathogens due to the fact that they ...

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 ...

AU - Yang, X.. PY - 2013/8. Y1 - 2013/8. N2 - Borrelia burgdorferi, the causative agent of Lyme disease, must adapt to two diverse niches, an arthropod vector and a mammalian host. RpoS, an alternative sigma factor, plays a central role in spirochetal adaptation to the mammalian host by governing expression of many genes important for mammalian infection. B. burgdorferi is known to be unique in metal utilization, and little is known of the role of biologically available metals in B. burgdorferi. Here, we identified two transition metal ions, manganese (Mn2+) and zinc (Zn2+), that influenced regulation of RpoS. The intracellular Mn2+ level fluctuated approximately 20-fold under different conditions and inversely correlated with levels of RpoS and the major virulence factor OspC. Furthermore, an ...
Abstract Transovarial transmission of two strains of yellow fever virus was demonstrated in three colonized geographical strains of Aedes aegypti following infection by intrathoracic inoculation. Infected progeny were detected in F1 offspring from only the first three ovarian cycles (OVC). The overall minimum filial infection rate for the first three OVC was 1:596; rates were lower in the second and third OVC. Virus survived in eggs for longer than 4 months and was recovered from progeny of three immersions of first OVC eggs. Infected progeny averaged a longer time to pupation than noninfected siblings. Transovarial transmission of virus was also demonstrated in first OVC progeny of Aedes mascarensis.
Millions of Lyme disease vector ticks are dispersed annually by songbirds across Canada, but often overlooked as the source of infection. For clarity on vector distribution, we sampled 481 ticks (12 species and 3 undetermined ticks) from 211 songbirds (42 species/subspecies) nationwide. Using PCR, 52 (29.5%) of 176 Ixodes ticks tested were positive for the Lyme disease spirochete, Borrelia burgdorferis.l. Immature blacklegged ticks,Ixodes scapularis, collected from infested songbirds had a B. burgdorferi infection prevalence of 36% (larvae, 48%; nymphs, 31%). Notably, Ixodes affinis is reported in Canada for the first time and, similarly, Ixodes auritulus for the initial time in the Yukon. Firsts for bird-parasitizing ticks include I. scapularis in Quebec and Saskatchewan. We provide the first records of 3 tick species cofeeding on passerines (song sparrow, Swainsons thrush). New host records reveal I. scapularis on the blackpoll warbler and Nashville warbler. We furnish the following first ...
Rickettsiae are obligate intracellular gram-negative bacteria transmitted by arthropod vectors. Rickettsiae sometimes cause disease in humans, typically with high fever, headache and occasionally an eschar.. In Sweden, Rickettsia helvetica, belonging to the spotted fever group, is the only tick-transmitted rickettsia found free in nature. The pathogenic roll of R. helvetica has not been fully investigated, but it has been implicated in aneruptive fever and cardiac disease.. This thesis describes parts of the transmission pathways of rickettsiae in Sweden. Rickettsia infection rates in ticks collected from birds were analysed, and the birds role as disseminators and reservoirs was studied. We found that more than one in ten ticks was infected with rickettsia bacteria, predominantly R. helvetica, and that migrating birds contribute not only to long-distance dispersion of bacteria, but also to an inflow of novel and potentially pathogenic rickettsia species, in this case R. monacensis and R. sp. ...

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease recently discovered in northeast and central China. SFTS cause high fatality rate of 12% and as high as 30% in some areas. The major clinical symptoms of SFTS are fever, vomiting, diarrhea, multiple organ failure, thrombocytopenia (low platelet count), leucopenia (low white blood cell count), and elevated liver enzyme level.SFTS occurs in rural areas from March to November, and a majority of cases are from April to July. In 2009 Xue-jie Yu and colleagues isolated the SFTS virus (SFTSV) from SFTS patients blood. SFTSV is a Phlebovirus in the family of Bunyaviridae. The life cycle of the SFTSV most likely involves arthropod vectors and animal hosts. Humans are accidental hosts and play no role in the life cycle of the SFTSV. SFTSV has been detected from Haemaphysalis longicornis ticks. The transmission routine of SFTSV is unknown, but person-to-person transmission either plays no role or at least is not an ...
