Evidence for genetic hybridization between Ixodes scapularis and Ixodes cookei

open access: yesCanadian Journal of Zoology, 2017
Ixodes scapularis Say, 1821, the black-legged tick, is becoming established in Canada. The northwards expansion of I. scapularis leads to contact between I. scapularis and I.

The neuropeptidomics of Ixodes scapularis synganglion

Journal of Proteomics, 2009
Ticks (Ixodoidea) likely transmit the greatest variety of human and animal pathogens of any arthropod vector. Despite their medical significance little data is available about the messenger molecules in the central nervous system that coordinate all physiological processes in these animals, including behaviour.

Identification of microRNAs in the Lyme Disease Vector Ixodes scapularis

open access: yesInternational Journal of Molecular Sciences, 2022
MicroRNAs (miRNAs) are a class of small non-coding RNAs involved in many biological processes, including the immune pathways that control bacterial, parasitic, and viral infections. Pathogens probably modify host miRNAs to facilitate successful infection, so they might be useful targets for vaccination strategies.

Vitellogenin and Ecdysteroid Titers in Ixodes scapularis during Vitellogenesis

The Journal of Parasitology, 1997
Ecdysteroids are the only hormones unequivocally identified thus far in ticks. We found a positive correlation between ecdysteroid concentration and vitellogenin synthesis in female Ixodes scapularis. Vitellogenin (Vg) synthetic activity was measured by an in vitro assay for Vg, involving incubations of the fat body with 35S-methionine and ...

New records of immature Ixodes scapularis from Mississippi

Journal of Vector Ecology, 2006
The role of immature Ixodes scapularis in the ecology of Lyme disease is well documented (Piesman 2002). In the northeastern and midwestern U.S., nymphal I. scapularis are abundant and are the most important vectors of the etiologic agent, Borrelia burgdorferi. This apparently is not the case in the southern U.S.

Forum: Reported Distribution of Ixodes scapularis and Ixodes pacificus (Acari: Ixodidae) in the United States

Journal of Medical Entomology, 1998
Lyme disease, caused by infection with Borrelia burgdorferi, is the most frequently reported arthropod-borne disease in the United States. To develop a national map of the distribution of the vectors of B. burgdorferi to humans (Ixodes scapularis Say and Ixodes pacificus Cooley & Kohls ticks), we sent questionnaires to acarologists, health officials ...
