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.

Although bacterial culture is considered ideal the difficulty and time involved make it impractical for large-scale use. Additionally nucleic acid-based detection techniques may be hindered by inhibitors in environmental and clinical samples low sensitivity and the absence of genus-specific primers (10 27 To address these issues we used whole-genome scanning based on the complete genomes of to identify host- and vector-blind ...
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.

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. ...

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.. ...
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 ...

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. Special mention to Debbie Stenner - 2nd lady, Ian Smith - 1st M50, Dan Sandford - 1st M40 and Helen Brown (running for Mynydd Du) was 1st Lady! Great running all! ... See MoreSee Less ...

This book is designed primarily as a textbook for graduate and postgraduate courses in Medical, Public Health and Veterinary Entomology. Its uniqueness is that its emphasis is on disease as opposed to arthropods. It includes general discussions of epidemiology, transmission, disease control, vector control and disease surveillance. In addition, it contains chapters oriented towards the many specific arthropod-borne diseases. Furthermore, the book discusses the many direct impacts that parasitic insects have on human and animal health. The arthropods themselves are dealt with in two introductory chapters.Medical Entomology: A Textbook on Public Health and Veterinary Problems Caused by Arthropods, Softcover reprint of the original 1st ed. 2000 was published 2000 under ISBN 9780792363217 and ISBN 0792363213.
