Phylogenetic analyses reveal bat communities in Northwestern Mexico harbor a high diversity of novel cryptic ectoparasite species

Ecology and Evolution, Volume 13, Issue 2, February 2023., 2023
Parasites are integral parts of the ecosystem. Using phylogenetic techniques, we found multiple novel lineages of bat bugs, flies, and ticks in Northwestern Mexico. For some ectoparasite species, haplotype distribution may reflect patterns of bat dispersal.

Behavior of Wild Pigs toward Conspecific Carcasses: Implications for Disease Transmission in a Hot, Semiarid Climate

Transboundary and Emerging Diseases, Volume 2023, Issue 1, 2023., 2023
Wild pigs (Sus scrofa) are a prolific, invasive species in the United States of America and act as vectors for many pathogens. An emerging pathogen of concern to the USA is African swine fever (ASF), a deadly viral disease affecting swine that is endemic to Africa and has spread to parts of Europe, Asia, and the Caribbean.

Current review of isoxazoline ectoparasiticides used in veterinary medicine

Journal of Veterinary Pharmacology and Therapeutics, Volume 45, Issue 1, Page 1-15, January 2022., 2022
Abstract The isoxazolines are a novel class of ectoparasiticides with potent inhibitory activity on glutamate‐ and gamma‐aminobutyric acid‐gated chloride channel located in nervous system of invertebrates. In recent years, studies have been performed to evaluate the efficacy and safety of isoxazolines against various types of ectoparasites, including ...

Effects of Sex, Life Stage, and Specific Blood Meals on Microbiome of Starved Ornithodoros turicata [PDF]

, 2022
Ticks carry and transmit more disease agents than any other arthropod vector. The composition of the microbiome within ticks may influence this ability, but many factors that influence their microbial composition remain to be elucidated.

Diversity and distribution of the tick-borne relapsing fever spirochete Borrelia turicatae.

PLoS Neglected Tropical Diseases, 2021
Borrelia turicatae is a causative agent of tick-borne relapsing fever (TBRF) in the subtropics and tropics of the United States and Latin America. Historically, B. turicatae was thought to be maintained in enzootic cycles in rural areas.

Imaging of Borrelia turicatae Producing the Green Fluorescent Protein Reveals Persistent Colonization of the Ornithodoros turicata Midgut and Salivary Glands from Nymphal Acquisition through Transmission. [PDF]

Appl Environ Microbiol, 2017
ABSTRACT Relapsing fever (RF) spirochetes colonize and are transmitted to mammals primarily by Ornithodoros ticks, and little is known regarding the pathogen's life cycle in the vector. To further understand vector colonization and transmission of RF spirochetes, Borrelia turicatae ...

Detection of Tickborne Relapsing Fever Spirochete, Austin, Texas, USA

Emerging Infectious Diseases, 2018
In March 2017, a patient became febrile within 4 days after visiting a rustic conference center in Austin, Texas, USA, where Austin Public Health suspected an outbreak of tickborne relapsing fever a month earlier.

Mevalonate-Farnesal Biosynthesis in Ticks: Comparative Synganglion Transcriptomics and a New Perspective. [PDF]

PLoS ONE, 2016
Juvenile hormone (JH) controls the growth, development, metamorphosis, and reproduction of insects. For many years, the general assumption has been that JH regulates tick and other acarine development and reproduction the same as in insects.

The relapsing fever spirochete Borrelia turicatae persists in the highly oxidative environment of its soft‐bodied tick vector

Cellular Microbiology, Volume 21, Issue 2, February 2019., 2019
Abstract The relapsing fever spirochete Borrelia turicatae possesses a complex life cycle in its soft‐bodied tick vector, Ornithodoros turicata. Spirochetes enter the tick midgut during a blood meal, and, during the following weeks, spirochetes disseminate throughout O. turicata.
