In the epidemiology of infectious diseases, the basic reproduction number, R0, has a number of important applications, most notably it can be used to predict whether a pathogen is likely to become established, or persist, in a given area. We used the R0 model to investigate the persistence of 3 tick-borne pathogens;Babesia microti, Anaplasma phagocytophilum andBorrelia burgdorferi sensu lato in...

Anaplasma phagocytophilum is an emerging tick-borne pathogen with both veterinary and human health implications. The role of wildlife hosts for this pathogen are not well defined, even thought roe deer (Capreolus capreolus) has been suggested to contribute to the occurrence of this tick-borne diseases in Europe. Therefore the aim of the present study was to investigate the potential role of thi...
Mathematical models of mosquito-borne pathogen transmission originated in the early twentieth century to provide insights into how to most effectively combat malaria. The foundations of the Ross-Macdonald theory were established by 1970. Since then, there has been a growing interest in reducing the public health burden of mosquito-borne pathogens and an expanding use of models to guide their co...
Ixodes ricinus ticks are vectors of numerous human and animal pathogens. They are host generalists able to feed on more than 300 vertebrate species. The prevalence of tick-borne pathogens is influenced by host-vector-pathogen interactions that results in spatial distribution of infection risk. Broad-range polymerase chain reaction electrospray ionization mass spectrometry (PCR/ESI-MS) was used ...
the pistachio gardens in iran rival other countries with 280000 hectares and rank first in the world in terms of annual production 300,000 mts. ecological factors for pistachio planting favor the growth of aspergillus flavus which produce aflatoxin as secondary metabolites which reduces pistachio exports. it is important to control a. flavus and its aflatoxin production to increase pistachio ex...
Pathogens and parasites can be strong agents of selection and often exhibit genetic specificity for individual host strains. Here we use a simple host–pathogen model to explore the consequences of host–pathogen specificity for selection on pathogen infectiousness and lethality. Pathogens that can transmit themselves more readily from host to host should have a clear reproductive advantage, as s...
