Investigations into the vector competency of arthropods for two Ehrlichias: Ehrlichia risticii and Cowdria ruminantium
Three studies relating to the vector competency of several species of ticks and <i>Simulium</i> spp. (blackflies) for <i>Ehrlichia risticii</i>, causative agent of Potomac horse fever (PHF) and <i>Amblyomma variegatum</i> for <i>Cowdria ruminantium</i>, causative agent of heartwater, are described. …

Filarial infection in mosquitoes of Northern California
… are a type of nematode that requires arthropod vectors for transmission between hosts. Filarial parasites vary among species of vertebrate hosts and can cause varying symptoms in hosts, including death. The presence of filarial parasites can influence host populations and can be costly to …

Vector competence of Ochlerotatus trivittatus (Coquillett), Aedes albopictus (Skuse), and Culex pipiens (L) (Diptera: Culicidae) for West Nile virus
… species of mosquitoes are the primary amplifying vectors. Many species of mammals are also susceptible to WNV but develop viremias that seldom exceed 105.0 CID50s/ml. Mammals may play a significant role in WNV ecology if mosquitoes that feed on them during periods of viremia can be infected and …

Analysis of genetic variation in Pediculus humanus and Populus trichocarpa
… important difference being that only body lice vector disease to humans. The first question is: Are body lice (Pediculus humanus coporis) and head lice (Pediculus humanus capitis) the same species? A total of 10,771 body louse and 10,770 head louse transcripts were predicted from a combined …
