Babesial vector tick defensin against Babesia sp. parasites.
Antimicrobial peptides are major components of host innate immunity, a well-conserved, evolutionarily ancient defensive mechanism. Infectious disease-bearing vector ticks are thought to possess specific defense molecules against the transmitted pathogens that have been acquired during their evolution. We found in the tick Haemaphysalis longicornis a novel parasiticidal peptide named longicin th...
متن کاملBabesia sp.: emerging intracellular parasites in Europe.
The emergence of Lyme borreliosis as the most prevalent arthropod disease of humans in the temperate northern hemisphere has resulted in renewed interest in human babesiosis, transmitted by the same tick vectors. The advent of new molecular tools has made possible a reappraisal of the main parasites involved (Babesia divergens in Europe and Babesia microti in the USA). B. divergens is probably ...
متن کاملA Cysteine Protease Is Critical for Babesia spp. Transmission in Haemaphysalis Ticks
Vector ticks possess a unique system that enables them to digest large amounts of host blood and to transmit various animal and human pathogens, suggesting the existence of evolutionally acquired proteolytic mechanisms. We report here the molecular and reverse genetic characterization of a multifunctional cysteine protease, longipain, from the babesial parasite vector tick Haemaphysalis longico...
متن کاملProspects for recombinant vaccines against Babesia bovis and related parasites.
Babesial parasites infect cattle in tropical and temperate regions of the world and cause significant morbidity and mortality. Discovery of protective antigens that could be used in a killed vaccine has been slow and to date there are few promising vaccine candidates for cattle Babesia. This review describes mechanisms of protective innate and adaptive immune responses to babesial parasites and...
متن کاملDeciphering Babesia-Vector Interactions
Understanding host-pathogen-tick interactions remains a vitally important issue that might be better understood by basic research focused on each of the dyad interplays. Pathogens gain access to either the vector or host during tick feeding when ticks are confronted with strong hemostatic, inflammatory and immune responses. A prominent example of this is the Babesia spp.-tick-vertebrate host re...
