Antigenic variation in vector-borne pathogens.
Several pathogens of humans and domestic animals depend on hematophagous arthropods to transmit them from one vertebrate reservoir host to another and maintain them in an environment. These pathogens use antigenic variation to prolong their circulation in the blood and thus increase the likelihood of transmission. By convergent evolution, bacterial and protozoal vector-borne pathogens have acqu...
متن کاملStructural vaccinology to thwart antigenic variation in microbial pathogens.
P athogenic microbes evolve continuously to adapt to the immune responses of their infected hosts. For some pathogens, this presents a formidable challenge, because host adaptive immune responses may neutralize key virulence attributes of the microbe, thereby establishing immunity to subsequent infection (1). Under such immune selection, microbes evolve variants with altered antigenic but unalt...
متن کاملThe impact of community organization on vector-borne pathogens.
Vector-borne zoonotic disease agents, which are known to often infect multiple species in the wild, have been identified as an emerging threat to human health. Understanding the ecology of these pathogens is especially timely, given the continued anthropogenic impacts on biodiversity. Here, we integrate empirical scaling laws from community ecology within a theoretical reservoir-vector-pathogen...

The effect of different compost-soil ratios on the incidence of Pythium aphanidermatum causing tomato damping off was tested in a greenhouse experiment. The inoculum density of 5% was determined to be suitable for inoculation in compost experiments based on investigations of disease incidence with 5, 10 and 20% inoculum densities. To evaluate the effect of compost on incidence of tomato damping...
متن کاملControl and Management of Vector-Borne Diseases in Disaster Conditions
Disasters are a set of unexpected situations that occur as a result of natural misadventure or human manipulations. Depending on the type, time, and location of the events, the insect population causing vector-borne diseases is affected, which may eventually lead to widespread epidemics. Parasitic diseases such as malaria, leishmaniosis, arboviral diseases such as dengue fever, West Nile enceph...
