Exosomes are membrane-bound vesicles. They considered as waste-management system of cells, crucial for intercellular communication information and have emerged to be mediators pathogen transmission. Pathogen derived exosomes advance infections by suppression host immune response, transmission pathogen-related molecules evasion. The ability from the virus infected cells modulate response and/or ...
About 60% of emerging infectious diseases in humans are of zoonotic origin. Their increasing number requires the development of new methods for early detection and monitoring of infectious agents in wildlife. Here, we investigated whether blood meals from hematophagous flies could be used to identify the infectious agents circulating in wild vertebrates. To this aim, 1230 blood-engorged flies w...
By extending a mechanistic model for the tick-borne pathogen systemic transmission with consideration of seasonal climate impacts, host movement as well co-feeding route, this paper proposes novel modeling framework describing spatial dynamics diseases. The net reproduction number tick growth and basic disease are derived, which predict global population transmission. Numerical simulations not ...
Deer support high tick intensities, perpetuating tick populations, but they do not support tick-borne pathogen transmission, so are dilution hosts. We test the hypothesis that absence of deer (loss of a dilution host) will result in either an increase or a reduction in tick density, and that the outcome is scale dependent. We use a complementary methodological approach starting with meta-analys...
Gaeumannomyces graminis var. tritici causes take-all disease, the most important root disease of cereal plants. Cereal plants are able to form a symbiotic association with soil-borne arbuscular mycorrhizal fungi which can provide bioprotection against soil-borne fungal pathogens. However, the bioprotective effect of arbuscular mycorrhizal fungi against soil-borne fungal pathogens might vary. In...
The geographic ranges of ticks and tick-borne pathogens are changing due to global and local environmental (including climatic) changes. In this review we explore current knowledge of the drivers for changes in the ranges of ticks and tick-borne pathogen species and strains via effects on their basic reproduction number (R 0), and the mechanisms of dispersal that allow ticks and tick-borne path...
Hepatitis C virus (HCV) is the most common blood-borne pathogen in the United States and is a leading cause of cirrhosis, need for liver transplantation, and liver-related mortality in women. Women should be offered testing if they fall in a high-risk group for exposure. Compared to men, women have higher rates of spontaneous HCV clearance after exposure and slower progression to cirrhosis but ...
Despite increasing studies targeted at host-pathogen interactions, vector-borne diseases remain one of the largest economic health burdens worldwide. Such diseases are vectored by hematophagous arthropods that deposit pathogens into the vertebrate host's skin during a blood meal. These pathogens spend a substantial amount of time in the skin that allows for interaction with cutaneous immune cel...
Background: To further minimize transmission risk of blood-borne viral and prion diseases, manufacturers of therapeutic animalor human-derived proteins have implemented improved in-process pathogen-removal procedures. Objectives: To evaluate removal of transmissible spongiform encephalopathy agents (prions) and viruses using Omega 100K VR membrane filtration system (Pall Filtron, Northborough, ...
