Novel Borrelia burgdorferi isolates from Ixodes scapularis and Ixodes dentatus ticks feeding on humans [PDF]

Journal of Clinical Microbiology, 1996
Seven cultures of Borrelia burgdorferi differing from strains B31 and ZS7 were identified from among 99 isolates from Ixodes scapularis ticks and from white-footed mice (Peromyscus leucopus) and 1 isolate from an Ixodes dentatus tick. Five of the six novel isolates from I. scapularis and the isolate from I.

Dual Disruption of the Immune Cytokine Spätzle Facilitates Fungal Infection of Diverse Insect Hosts

Advanced Science, Volume 13, Issue 1, 5 January 2026.
The Toll pathway is essential for insect defense against fungal pathogens. This works reports that fungal parasites employ two divergent virulent effectors to target the Toll receptor ligand Spätzle: a metalloprotease degrading it and a hairpin‐like effector hijacking it to block signal transduction. This dual strategy enables the fungus to kill a wide

Exploring the mialome of ticks: An annotated catalogue of midgut transcripts from the hard tick, Dermacentor variabilis (Acari: Ixodidae) [PDF]

, 2008
Background Ticks are obligate blood feeders. The midgut is the first major region of the body where blood and microbes ingested with the blood meal come in contact with the tick's internal tissues.

RNAi‐mediated gene silencing of a 26S proteasome subunit increases mortality of the Japanese beetle Popillia japonica

Pest Management Science, Volume 82, Issue 1, Page 1066-1078, January 2026.
We propose the regulatory particle non‐ATPase subunit 6 of the 26S proteasome as a first good promising RNA interference target candidate to control the Japanese beetle Popillia japonica. This will help to optimize a double‐stranded RNA insecticide against this priority pest with low off‐target effects on pollinators on a gene sequence‐based prediction.

When is a parasite not a parasite? Effects of larval tick burdens on white-footed mouse survival [PDF]

, 2014
Many animal species can carry considerable burdens of ectoparasites: parasites living on the outside of a host's body. Ectoparasite infestation can decrease host survival, but the magnitude and even direction of survival effects can vary depending on the

A Rare Presentation of Babesia‐Associated Splenic Infarction in an Immunocompetent Young Male With Mild Parasitemia

Case Reports in Medicine, Volume 2026, Issue 1, 2026.
Babesiosis is a vector‐borne protozoal disease primarily transmitted by the Ixodes scapularis tick, though it can also be transmitted through blood transfusions from infected donors. The illness can be asymptomatic or present with mild flu‐like symptoms.

Exploring the sialome of the tick Ixodes scapularis

Journal of Experimental Biology, 2002
SUMMARY To attempt description of the set of mRNA and protein (sialome) expressed in the salivary glands of the tick Ixodes scapularis, we randomly sequenced 735 clones of a full-length salivary gland cDNA library of this arthropod and performed Edman degradation of protein bands from salivary gland homogenates (SGH) and saliva separated

Saliva from nymph and adult females of Haemaphysalis longicornis: a proteomic study [PDF]

, 2015
BACKGROUND: Haemaphysalis longicornis is a major vector of Theileria spp., Anaplasma phagocytophilum, Babesia spp. and Coxiella burnetti in East Asian countries. All life stages of ixodid ticks have a destructive pool-feeding style in which they create a
