| genomic insights into the ixodes scapularis tick vector of lyme disease. | ticks transmit more pathogens to humans and animals than any other arthropod. we describe the 2.1 gbp nuclear genome of the tick, ixodes scapularis (say), which vectors pathogens that cause lyme disease, human granulocytic anaplasmosis, babesiosis and other diseases. the large genome reflects accumulation of repetitive dna, new lineages of retro-transposons, and gene architecture patterns resembling ancient metazoans rather than pancrustaceans. annotation of scaffolds representing ∼57% of the ge ... | 2016 | 26856261 |
| origin and evolution of rickettsial plasmids. | rickettsia species are strictly intracellular bacteria that have undergone a reductive genomic evolution. despite their allopatric lifestyle, almost half of the 26 currently validated rickettsia species have plasmids. in order to study the origin, evolutionary history and putative roles of rickettsial plasmids, we investigated the evolutionary processes that have shaped 20 plasmids belonging to 11 species, using comparative genomics and phylogenetic analysis between rickettsial, microbial and no ... | 2016 | 26866478 |
| a brown dog tick (rhipicephalus sanguineus) bite at sea. | medical officers (mos) and medical branch ratings (mbrs) must maintain an awareness of the risk of vector-borne diseases among deployed personnel. personnel working in the maritime environment may not expect to be at risk of tick bites, as ticks typically occupy habitats with dense vegetation such as forests or scrub land. however, tick-borne pathogens can cause serious and sometimes fatal disease, and therefore the risk of tick bites and associated diseases should be recognised. we present a ca ... | 2015 | 26867423 |
