Lethal Case of Bourbon Virus Leading to Shock and ECMO Utilization

Case Reports in Infectious Diseases, Volume 2026, Issue 1, 2026.
We present a lethal case of Bourbon virus infection in a 63‐year‐old Caucasian, diabetic male who was previously in good health. The patient had spent time in the wooded areas of Bourbon County, Kansas, and removed three ticks from his body 5 days prior to presentation.

Fine structure of tarsal sensilla in the tick Amblyomma americanum (L.) [PDF]

Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1971
Selected tarsal bristles of the tick Amblyomma americanum (L.) (Acarina: Ixodidae; nymphal stage) were studied by means of scanning and transmission electron microscopy. All sensilla are multi-innervated and have thick cuticular walls containing either an elaborate pore canal system or a single slit opening at the tip.

Managing Alpha‐Gal Allergy in a Case of Bioprosthetic TAVR

Case Reports in Immunology, Volume 2026, Issue 1, 2026.
Alpha‐gal syndrome (AGS) is an uncommon IgE‐mediated allergy to mammalian‐derived products, caused by sensitization to the oligosaccharide galactose‐α‐1,3‐galactose (alpha‐gal) after tick exposure. Although AGS is best recognized for delayed anaphylaxis following ingestion of red meat, its implications for exposure to mammalian‐derived biomaterials ...

The mitochondrial genome of the lone star tick (Amblyomma americanum)

Ticks and Tick-borne Diseases, 2015
Amblyomma americanum is an abundant tick in the southeastern, midwestern, and northeastern United States. It is a vector of multiple diseases, but limited genomic resources are available for it. We sequenced the complete mitochondrial genome of a single female A. americanum collected in Georgia using the Illumina platform. The consensus sequence was 14,

Relative Risk for Ehrlichiosis and Lyme Disease in an Area Where Vectors for Both Are Sympatric, New Jersey, USA

Emerging Infectious Diseases, 2017
The lone star tick, Amblyomma americanum, is a vector of Ehrlichia chaffeensis and E. ewingii, causal agents of human ehrlichiosis, and has demonstrated marked geographic expansion in recent years. A.

Mitochondrial Dysfunction in Ehrlichia canis Infection

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Transmitted by tick vectors, Ehrlichia canis (E. canis) is a Gram‐negative, obligate intracellular bacterium of zoonotic concern that infects both canine and human hosts. Its pathogenesis centers on the targeting of mononuclear phagocytes, where it establishes an intracellular niche by suppressing phagolysosomal fusion and evading immune detection ...

Identification and characterization of proteins in the Amblyomma americanum tick cement cone [PDF]

International Journal for Parasitology, 2018
The adaptation of hard ticks to feed for long periods is facilitated by the cement cone, which securely anchors the tick mouthparts onto host skin and protects the tick from being groomed off by the host. Thus, preventing tick cement deposition is an attractive target for the development of innovative tick control.

Transmission of Cytauxzoon felis by injection of Amblyomma americanum salivary glands

Parasitology International, 2023
Cytauxzoonosis is a life-threatening disease of cats, caused by the tick-borne piroplasmid hemoparasite, Cytauxzoon felis. Current experimental models for cytauxzoonosis rely on either tick transmission or direct injection of infected cat tissues.

Ecological dynamics of blacklegged ticks, vertebrate hosts, and associated zoonotic pathogens in northeastern forests

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract Specific host‐tick interactions in temperate forest systems influence variation in density and infection prevalence of nymphal blacklegged tick (Ixodes scapularis). The density of infected nymphs (DIN), which is the product of nymphal infection prevalence (NIP) and density of questing nymphs (DON), influences the risk of human exposure to tick‐
