Cytauxzoon felis in salivary glands of Amblyomma americanum. [PDF]

Ticks Tick Borne Dis, 2023
Cytauxzoon felis is a tick-borne piroplasmid hemoparasite that causes life-threatening disease in cats. Despite the critical role that ticks play in pathogen transmission, our knowledge regarding the C. felis life cycle remains limited to the feline hosts. Specific life stages of C.

Spatial and temporal activity patterns of Amblyomma americanum. [PDF]

Parasit Vectors
Abstract Background Estimates of tick abundance and distribution are used to determine the risk of tick-host contact. Tick surveys provide estimates of distributions and relative abundance for species that remain stationary and wait for passing hosts (i.e.

Lone Star Ticks (Amblyomma americanum):: An Emerging Threat in Delaware. [PDF]

Dela J Public Health, 2021
Public health messaging in the eastern United States has historically underemphasized the risks posed by lone star ticks (Amblyomma americanum), focusing instead on blacklegged ticks (Ixodes scapularis). This gap persists despite mounting evidence that lone star ticks also play an important role in disease ecology as confirmed vectors for a wide ...

Direct injection of Amblyomma americanum ticks with Cytauxzoon felis. [PDF]

Ticks Tick Borne Dis, 2022
Cytauxzoon felis is a tick-borne hemoprotozoan parasite that causes life-threatening disease in domestic cats in the United States. Currently, the platforms for C. felis research are limited to natural or experimental infection of domestic cats. This study aims to develop an alternative model by infecting Amblyomma americanum ticks with C.

Mapping the distribution of Amblyomma americanum in Georgia, USA. [PDF]

Parasit Vectors
Abstract Background Amblyomma americanum, the lone star tick, is an aggressive questing species that harbors several pathogens dangerous to humans in the United States. The Southeast in particular has large numbers of this tick due to the combined suitable climate and habitats throughout the region.

The bacterial community of the lone star tick (Amblyomma americanum). [PDF]

Parasit Vectors, 2021
Abstract Background The lone star tick (Amblyomma americanum), an important vector of a wide range of human and animal pathogens, is very common throughout the East and Midwest of the USA. Ticks are known to carry non-pathogenic bacteria that may play a role in their vector competence for pathogens.

A Case of Illness Following a Bite by a Male Lone Star Tick (<i>Amblyomma americanum</i> Linnaeus) Infected With <i>Ehrlichia</i> sp. and <i>Rickettsia amblyommatis</i> in Connecticut, United States. [PDF]

Clin Case Rep
A case of local lymphadenopathy and a flu‐like illness in a man, following a bite by a male lone star tick infected with Ehrlichia sp. and Rickettsia amblyommatis. ABSTRACT The lone star tick (Amblyomma americanum Linnaeus) is a species commonly found in the southeastern U.S., but in recent years its populations have expanded northward, resulting in an

Factors affecting the microbiome of Ixodes scapularis and Amblyomma americanum. [PDF]

PLoS One, 2020
The microbial community composition of disease vectors can impact pathogen establishment and transmission as well as on vector behavior and fitness. While data on vector microbiota are accumulating quickly, determinants of the variation in disease vector microbial communities are incompletely understood.

Amblyomma americanum

, 2023
3. Amblyomma americanum (Linnaeus, 1758). Nearctic: 1) USA (Lado et al. 2020). Although Camicas et al. (1998) treated Amblyomma americanum as a Nearctic and Neotropical species, Guglielmone et al. (2003, 2014, 2021) listed and discussed several records of this tick from Neotropical countries and a few from other zoogeographic regions, including Russia (
