The Asian longhorned tick (Haemaphysalis longicornis) is making its presence felt across the eastern United States—but not ...

An invasive species of tick, which can be found in New York—including on Staten Island—has recently been identified by scientists in another state as the carrier of a dangerous bacterium.

However, the recent case of a tick carrying Ehrlichia chaffeensis, the bacteria behind HME, in Connecticut involved the longhorned tick, a tick species native to eastern Asia.

A tick that's rapidly spreading through Pennsylvania and elsewhere was found to carry a potentially dangerous bacterium.

“This new pathogen is ehrlichia chaffeensis. Even though we call it new, this pathogen has been around because it is primarily transmitted by the lone star tick,” Dr. Goudarz Molei, ...

Human monocytic ehrlichiosis (HME) is a tick-borne illness caused by Ehrlichia chaffeensis.The distribution of this rickettsial disease parallels that of its major tick vectors, the Lone Star tick ...

Ehrlichia chaffeensis is an obligate intracellular bacterium responsible for human monocytic ehrlichiosis, a potentially severe tick-borne disease. As a pathogen that exclusively replicates within ...

A bacteria called Ehrlichia chaffeensis tends to spread through the lone star tick, which typically infects a type of white blood cell and causes Ehrlichiosis, according to officials. Local ...

Ehrlichia chaffeensis is an obligate intracellular bacterium responsible for human monocytic ehrlichiosis. Its pathogenesis hinges on the bacterium’s ability to invade mononuclear phagocytes ...

While Lyme disease gets the most attention – and affects the most people – there are other tick-borne bacteria and diseases that have also been found spreading in the U.S.

Several species of bacteria cause ehrlichiosis, though most cases are tied to Ehrlichia chaffeensis. The disease is rarely documented, though cases have been increasing over time.
