(21 July 1994) In response to questions resulting from the recent news reports of 'new tick-borne illness causing deaths in the Midwest,' the following information is provided: Ehrlichioses are diseases caused by rickettsia-like organisms, which are extremely small, intracellular bacteria belonging to the family Rickettsiaceae, genus Ehrlichia (Tansill 1984). Ehrlichiosis was first described in Algerian dogs in 1935 (Donatien et al. 1935, Bakken 1994), and in the 1960s, a number of military guard dogs stationed in Vietnam died from complications of a hemorrhagic illness caused by Ehrlichia canis (Keefe et al. 1982). Human ehrlichiosis is a more recently recognized disease. The first diagnosed case occurred in 1986 in a 51-yr-old man from Detroit who had been exposed to ticks in a rural area of Arkansas (Maeda et al. 1987). In 1990, the agent of human ehrlichiosis was isolated from the blood of a U.S. Army reservist at Fort Chaffee, AR (Dawson et al. 1991). The newly recognized organism was named E. chaffeensis

Newly discovered rickettsial diseases transmitted by ticks. Includes symptoms, treatment, and prevention.
  • Most infections are mild or without symptoms, but some can be severe and life-threatening. Ehrlichiosis can usually be treated with antibiotics. Prevention centers on avoiding exposure to ticks and removing attached ticks promptly.
What is ehrlichiosis? Ehrlichiosis is a newly recognized and potentially life-threatening disease that is spread by ticks. Since 1986, two types of human ehrlichiosis have been identified in the United States: human monocytic ehrlichiosis (HME) and human granulocytic ehrlichiosis (HGE). The illnesses differ in the types of white blood cells they attack either monocytes or granulocytes. What is the infectious agent that causes ehrlichiosis? Ehrlichiosis is caused by specialized bacteria called rickettsiae. HME is caused by Ehrlichia chaffeensis . HGE is caused by a newly identified but as yet unnamed Ehrlichia Where is ehrlichiosis found? In the United States, HME has so far been concentrated in the southeast and south-central regions. HGE has been found mainly in the upper midwestern and northeastern states, but also in northern California. How do people get ehrlichiosis?

Includes symptoms, carriers, prevention, and proper tick removal techniques.
A recently discovered and sometimes fatal illness carried by ticks can be difficult to distinguish from Lyme disease . This illness, called Human Granulocytic Ehrlichiosis (HGE) , is spread by the deer tick, the same tick that carries Lyme disease. The following information has been compiled from various sources by Thomas H. Nicholls, research wildlife biologist, working on bird vectors of these diseases. The following key facts are designed to provide field workers with important information needed to protect themselves. The chief vector of both diseases is the deer tick, Ixodes scapularis=(I. dammini) . Both diseases are caused by bacteria. The white-footed mouse is the principal reservoir host for these bacteria in nature with deer being an important tick host. Early detection, disease identification, and treatment are critical in preventing long term complications caused by these diseases Laboratory diagnostic tests are not 100% reliable, especially during the first 3 weeks after infection. The most reliable readily available test is the Western blot and patients should be sure to ask for this to be performed. A more sophisticated test

Species Jump: Human Ehrlichiosis-
Mutant or Emergence?
Ehrlichia are gram negative, nonmotile, obligate intracellular coccobacilli belonging to the family Rickettsiaceae with much similarity both in structure and disease to the pathogens responsible for Rocky Mountain Spotted Fever,Q-fever, and Typhus. Ehrlichiosis is a tick borne zoonotic infection which passes into mammalian host blood via tick bites. Three tick species have been identified as vectors of Ehrlichia infection; Ixodes scapularis (deer tick), Amblyomma americanum (Lone Star tick), and Dermacentor variabilis (American Dog tick).
Clinical Signs and Symptoms:
Symptoms of ehrlichiosis in cattle, dogs, and horses resemble the human infection, although horses developswollen legs as well, which clues veterinarians to the possibility of Ehrlichia infection. One researcher, Dr. John E. Madigan at university of California Davis school of veterinary medicine has noted correlation between outbreaks of equine ehrlichiosis and human cases. "If horses are getting it (ehrlichiosis) in a certain geographical region, people are getting it also," he said. "Veterinarians are very skilled at identifying ehrlichiosis in horses. The appearance of the disease in horses should serve as a marker for public health officials to the potential of human infections occurring in the same area.
Ehrlichia bacteria are susceptible to a broad spectrum of antibiotics, with tetracycline and doxycycline the drugs of choice. Since these drugs can result in abnormal tooth coloration in children, infected children are usually treated with chloramphenicol as an effective alternative. Severe cases may require hospitalization in order to monitor organ function and leukocyte titers and to administer intraveinous fluid replacement. Additional antibiotics may be necessary if secondary infection occurs. There have been cases of spontaneous recovery in the absence of treatment.

Introduction Toward the end of the 19th century, scientists began to understand the important potential for ticks to act as transmitters of disease. In the last decades of the 20th century, several tick-borne diseases have been recognized in the United States, including babesiosis Lyme disease , and ehrlichiosis. Ehrlichiosis is caused by several bacterial species in the genus Ehrlichia (pronounced err-lick-ee-uh) which have been recognized since 1935. Over several decades, veterinary pathogens that caused disease in dogs, cattle, sheep, goats, and horses were identified. Currently, three species of Ehrlichia in the United States and one in Japan are known to cause disease in humans; others could be recognized in the future as methods of detection improve. In 1953, the first ehrlichial pathogen of humans was identified in Japan. Sennetsu fever, caused by

Questions and Answers What is ehrlichiosis?
Ehrlichiosis is the general name used to describe several bacterial diseases that affect animals and humans. These diseases are caused by the organisms in the genus Ehrlichia . Worldwide, there are currently four ehrlichial species that are known to cause disease in humans. How do people get ehrlichiosis?
In the United States, ehrlichiae are transmitted by the bite of an infected tick. The lone star tick ( Amblyomma americanum ), the blacklegged tick ( Ixodes scapularis ), and the western blacklegged tick ( Ixodes pacificus ) are known vectors of ehrlichiosis in the United States. Ixodes ricinus is the primary vector in Europe. What are the symptoms of ehrlichiosis?
The symptoms of ehrlichiosis may resemble symptoms of various other infectious and non-infectious diseases. These clinical features generally include fever, headache, fatigue, and muscle aches. Other signs and symptoms may include nausea, vomiting, diarrhea, cough, joint pains, confusion, and occasionally rash. Symptoms typically appear after an incubation period of 5-10 days following the tick bite.

Canine Ehrlichiosis
Ehrlichiosis, often called tick fever or tropical canine pancytopenia, is a tick-transmitted disease affecting dogs. The brown dog tick carries the organism causing Ehrlichiosis and transmits the disease while feeding on the dog’s blood. Symptoms
The disease has two phases, acute and chronic. The acute phase occurs 1-3 weeks following tick exposure. Clinical signs of illness are rather nonspecific and may include listlessness, swollen lymph nodes, anorexia, fever, and discharge from the nose and eyes. The signs of the chronic phase may include those mentioned for the acute phase plus nosebleeds or other abnormal bleeding and weight loss. The chronic phase may occur several months following the acute phase.

The Role of Disease Surveillance in the Watch for Agro-terrorism or Economic Sabotage FAS addresses these issues through public education and international collaboration. The project's operational arm, ILIAD-Tanzania , is a pilot test of a surveillance system designed for remote rural areas in developing or reorganizing countries. Eschewing passive surveillance in favor of a pro-active, response-oriented, continuously operating network that begins at the village level, this system offers the promise of timely and accurate disease detection, diagnosis, prevention, and control. As a fully collaborative program between veterinary service workers, local farmers, wildlife conservation personnel and local governments, it provides a logistical framework for treatment, education and outbreak reporting. It is anticipated that the program will, over time, alleviate poverty in remote villages by increasing livestock and poultry production, control zoonotic diseases in human populations, and prevent disease epidemics in wild animal populations.

    Human Ehrlichiosis is a disease caused by rickettsial type organisms that are transmitted in part by the SAME TICKS that carry Lyme disease. Ehrlichiosis usually presents with high fever, malaise, headache, myalgia, sweats, and nausea. Patients diagnosed with Ehrlichia should also be tested for Lyme disease due to the fact that co-infections have been documented in several patients. There are two forms of the disease caused by the Ehrlichia species: E. chaffeensis and E. phagocytophilia , which cause the human diseases, Human Monocytic Ehrlichiosis (HME) and Human Granulocytic Ehrlichiosis (HGE), respectively. HME has been linked to the bites of Amblyomma Americanum (Lone Star Tick) and HGE has been closely linked to the bites of Ixodes Scapularis and Ixodes Pacificus . The Dermacentor Variabilis (dog tick) has also been suggested in the transmission of both. Seroconversion usually occurs between two and four weeks after infection. HME: First described in 1987 and confirmed in 30 states, predominately in the southeast and mid-atlantic states. HME has also been found in Europe and Africa.

    Ehrlichiosis Antibodies Definition Return to top Erhlichiosis is an infectious disease transmitted by the bite of a tick Causes, incidence, and risk factors Return to top Ehrlichiosis is a disease caused by Ehrlichia organisms. It was first described in 1990. The two specific organisms that have been implicated are Ehrlichia chaffeensis and granulocytic Ehrlichia. The Ehrlichia bacteria belong to the family Rickettsiae. Rickettsial organisms are responsible for a number of serious diseases with worldwide distribution such as Rocky Mountain spotted fever typhus murine typhus , scrub typhus, Queensland tick typhus, Boutonneuse fever , North Asian tick-borne rickettsiosis, rickettsial pox, and others. All of these diseases require an insect (tick, flea, mite) to transmit them to humans or other animals. The infectious organism of ehrlichiosis is transmitted to humans by the bite of a tick. Rickettsiae are often associated with a specific tick. Ehrlichia inhabit the Lone Star tick (Amblyomma americanum), the American dog tick (Dermacentor variabilis), and the deer ticks (Ixodes dammini and Ixodes scapularis). (NOTE: the deer tick is also the carrier of
