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.

Detection of Babesia, Borrelia, Anaplasma, and Rickettsia spp. in Adult Black-Legged Ticks (Ixodes scapularis) from Pennsylvania, United States, with a Luminex Multiplex Bead Assay

Vector Borne and Zoonotic Diseases, 2020
Ixodes scapularis, the black-legged tick, harbors multiple organisms and transmits several pathogens to animals and humans. To determine the presence of tick-borne microorganisms carried by I. scapularis in Pennsylvania, 299 adult I.

Xenodiagnosis Using Ixodes scapularis Larval Ticks in Humans

2017
Xenodiagnosis is the use of a natural vector to detect the presence of an organism, and xenodiagnosis using Ixodes ticks has long been used by entomologists in Lyme disease research to provide evidence of the host's infectious status with Borrelia burgdorferi.

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 ...

Tick Artificial Membrane Feeding for Ixodes scapularis.

Journal of visualized experiments : JoVE, 2022
Ticks and their associated diseases are an important topic of study due to their public health and veterinary burden. However, the feeding requirements of ticks during both study and rearing can limit experimental questions or the ability of labs to research ticks and their associated pathogens.

Teratological NymphalIxodes scapularis(Acari: Ixodidae) From Wisconsin

Journal of Medical Entomology, 2015
Abnormalities of physiological development (teratological forms) in ticks are rare. The occurrence of gigantism, dwarfism, gynandromorphs, missing legs, extra legs, and asymmetries is most often reported from lab-reared specimens, but has been observed in field-collected specimens.

Survival of Ixodes scapularis (Acari: Ixodidae) Exposed to Cold

Journal of Medical Entomology, 1996
The cold hardiness of Ixodes scapularis Say unengorged larvae, engorged larvae, unengorged nymphs, engorged nymphs, and unengorged adults was evaluated. Ticks were exposed to cold for 2 or 8 h at a range of temperatures. Likelihood ratio tests and LT50 estimates were used to evaluate cold hardiness.

Passive Tick Surveillance: Exploring Spatiotemporal Associations of Borrelia burgdorferi (Spirochaetales: Spirochaetaceae), Babesia microti (Piroplasmida: Babesiidae), and Anaplasma phagocytophilum (Rickettsiales: Anaplasmataceae) Infection in Ixodes scapularis (Acari: Ixodidae)

Vector Borne and Zoonotic Diseases, 2020
Ixodes scapularis transmits a group of pathogens, including Borrelia burgdorferi, Babesia microti, and Anaplasma phagocytophilum, the causative agents for Lyme disease, babesiosis, and anaplasmosis, respectively. I.
