A practical protocol to prepare paraffin-embedded whole tick histology sections

Yang, T. S., LaDouceur, E. E. B., Baumgartner, W. A., Marr, H. S., Karounos, M., Robertson, J., … Birkenheuer, A. J. (2023, March 23). Ticks and Tick-Borne Diseases, Vol. 14.

By: T. Yang  n, E. LaDouceur, W. Baumgartner *, H. Marr n, M. Karounos n, J. Robertson n , N. Whitehurst n, L. Miller n, A. Birkenheuer n 

MeSH headings : Animals; Humans; Fixatives; Paraffin Embedding; Ixodes; Tick-Borne Diseases
topics (OpenAlex): Vector-borne infectious diseases; Vector-Borne Animal Diseases; Viral Infections and Vectors
TL;DR: A feasible protocol to prepare high quality paraffin-embedded whole tick histology sections is described that uses commonly available tools, reagents and standard histologic equipment and should allow any investigator to easily make adjustments to this protocol as needed based on their experimental goals.

Yang, T. S., Reichard, M. V., Thomas, J. E., Marr, H. S., Karounos, M., Hyatt, J., … Birkenheuer, A. J. (2023, April 20). Parasitology International, Vol. 95.

By: T. Yang  n, M. Reichard *, J. Thomas *, H. Marr n, M. Karounos n, J. Hyatt*, C. Miller *, A. Birkenheuer n 

author keywords: Feline; Cytauxzoon felis; Sporozoite; Ticks; Salivary glands
MeSH headings : Animals; Cats; Amblyomma; Ixodidae / parasitology; Protozoan Infections, Animal / parasitology; Ticks / parasitology; Piroplasmida / physiology; Felis; Cat Diseases
topics (OpenAlex): Vector-borne infectious diseases; Parasites and Host Interactions; Mosquito-borne diseases and control
TL;DR: This study validates the feasibility of collecting infectious sporozoites from C. felis-infected ticks that can be used to infect naïve cats and has the potential to expand resources to study C.Felis and further advance research in this field. (via Semantic Scholar)

Cytauxzoon felis in salivary glands of Amblyomma americanum

Yang, T. S., Reichard, M. V., Thomas, J. E., Miller, L. S., Marr, H. S., Karounos, M., … Birkenheuer, A. J. (2022, October 20). Ticks and Tick-Borne Diseases, Vol. 14.

By: T. Yang  n, M. Reichard *, J. Thomas *, L. Miller n, H. Marr n, M. Karounos n, A. Bell n, A. Birkenheuer n 

author keywords: Cytauxzoon felis; Sporozoites; In situ hybridization; Tick; Salivary glands
MeSH headings : Cats; Animals; Amblyomma; Microscopy, Electron, Transmission; Salivary Glands
topics (OpenAlex): Vector-borne infectious diseases; Vector-Borne Animal Diseases; Viral Infections and Vectors
TL;DR: The first direct visualization of any developing stage of C. felis within the tick host has been visualized microscopically, and it is believed that sporozoites in tick salivary glands (SG) have similar potential for cytauxzoonosis. (via Semantic Scholar)
