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.

Hamer, Gabriel - Texas A&M University (TAMU) Scholar profile, educations, publications, research, grants, awards, courses, concepts, and topics. Research in the Hamer Lab broadly investigates the ecology of infectious diseases of humans, wild animals, and domestic animals, with particular attention to those transmitted by arthropod vectors (e.g. mosquitoes, ticks, kissing bugs). We have focused primarily on vector-host interactions that lead to parasite amplification and increased disease risk. We utilize multidisciplinary tools to studying these complex disease systems, including molecular biology, landscape epidemiology, eco-immunology, and ecological modeling. A goal of our research is to elucidate mechanisms of transmission across space and time that facilitate ecological management of diseases with effective intervention and preventative strategies.

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 ...

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. ...

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.

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.. ...
Having a comfortable spot to sit down can never be underestimated. Thanks to Foresters Financial Lakehead Legacy, Thunder Bay Regional Health Sciences Centre now has two new spots where one can pause and find a spot to sit outside.. Recently they installed a new bench at the East Entrance, along with picnic tables in the ground floor courtyard (pictured above); an especially lovely spot to sit in the summer and enjoy the surrounding gardens.. Kevin Herman, Canada Regional Councillor from Foresters Financial remarked, Were always very proud to give back to the Health Sciences Centre. We know the benches we installed last year are really well used, so it was an easy decision to add more.. Altogether Foresters Financial has given over $45,000 to several areas of our Hospital including Paediatrics, the Cancer Centre and, most recently, to items that can make a trip here more comfortable. Weve installed benches, but we also continue to assemble comfort kits for the Emergency Department, said ...

For arthropod-borne viruses, which comprised 39% of pathogenic viruses, the discovery rate peaked at three per year during 1960-1969, but subsequently fell nearly to zero by 1980; however, the rate of discovery of nonarboviruses remained stable at about two per year from 1950 through 2010. The period of highest arbovirus discovery coincided with a comprehensive program supported by The Rockefeller Foundation of isolating viruses from humans, animals, and arthropod vectors at field stations in Latin America, Africa, and India. The productivity of this strategy illustrates the importance of location, approach, long-term commitment, and sponsorship in the discovery of emerging pathogens. ...

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 ...
