The Causative Agent Of Human Monocytotrophic Ehrlichiosis

A person can acquire Lyme disease by the bite of an infected tick. This disease is transmitted by deer ticks or black-legged ticks. Ticks are tiny in size and as their bite is painless, people might not even realize that they have been bitten. Once an infected tick attaches itself to the skin, it is able to transmit the bacteria. This bacteria eventually ends up in the bloodstream. The duration of attachment necessary to transfer

Lyme disease has emerged as the most common vector borne infectious disease in the United States and has presented a growing challenge to public health officials over the past three decades. The infection represents a significant disease burden to the population of the United States with nearly 30,000 new cases diagnosed per year and an estimated additional 270,000 annual incident cases that go unreported. The disease results from a bacterial infection with the spirochete bacteria B. burgdorferi. This bacterial agent is transmitted to humans from the bite of a tick and is most commonly associated Ixodes species blacklegged ticks. These ticks represent the largest genus of the family Ixodidae and mainly inhabit temperate forest or grassland

Animal or zoophilic infections are usually periodic and restricted to the areas where the host animal is found. Microsporum canis, the cat and dog ringworm, is the commonest of the zoophilic infections worldwide and spread occurs directly from an infected animal and, probably, from contaminated furniture, floors and carpets in the home environment. I contrast, Anthropophilic dermatophytes are more common in the community. In some cases there is evidence to support the existence of localized epidemics of

“RMSF is the most common fatal human tick-borne disease in the United States, with a minimal average of 351 confirmed human cases occurring annually and undoubtedly many more going unreported” (Niebylski et al.).

They contract it when feeding on infected hosts. While deer are most commonly known for giving Lyme disease to ticks, rodents are the main threat. “Ostfeld’s research indicates that white-footed mice infect 75-95 percent of larval ticks that feed on them, while deer only infect about one percent” (Mercola). Urban sprawl and hunting has eliminated many of the mice’s natural predators allowing populations to grow and infected ticks to spread.

Lymes disease is present here in Nova Scotia and has also affected humans and dogs in different parts of North America. It is one of the most common tick-causing symptoms however only 5-10% of dogs are affected showing different forms of the disease. Living in Lunenburg & Queens County (NS), there seems to be a higher population of deer ticks, as well as other parts of the province. The deer ticks are the primary carrier of the disease. A tick carrying the bacteria (B.burgdorferi) that can cause Lyme disease can transmit it to a dog after filling itself with blood, which takes at least 48 hours. Even if it is attached for 48 hours, the dog may not contract the disease.

Ticks, they are most significant vectors of infectious diseases in the United States. These arachnids can host a scary medley of infectious bacterium, and they are increasing at an alarming rate with one CDC graph showing their numbers have almost tripled since 1995 (Lyme Stats). Some point to greater awareness, other point to climate change, while we don’t know exactly why their reach is growing we do know we have to be wary of the diseases they carry. While not all ticks are hosts, ticks carrying the Borrelia bacteria known for causing Lyme disease present a massive public health risk. Lyme is one most under researched Infectious diseases with the CDC estimating that somewhere between 300,000 and 3,000,000 people are infected annual.

Lyme is a disease that is transmitted through the bite of a tick. "It is caused by a spirochete – which is a corkscrew shaped bacterium called Borrelia burgdorferi" (About Lyme Disease. 2017). (Show Photo)

Unfortunately, people around the world struggle with deadly and rare diseases. From the outside looking in, these deadly and horrific diseases appear as something minor and easy to conquer. However, people everyday die from lack of resources and their inability to cope with the pain that these disease come with. The presentation Tick Tock discussed the horrific infection of lyme disease. Lyme disease is a bacterial infection transmitted to humans through the bite of an infected blacklegged tick on the west coast and on the east coast by ixodes ticks. The ticks infect the human with a bacterium called Borrelia burgdorferi. It is a corkscrew shaped bacterium. Ticks usually attach to the armpit, groin, or scalp. Lyme disease is found throughout the United States and sixty other countries. Most people get lyme disease from a tiny, immature form

Lyme disease is transmitted to humans by the bite of infected ticks of the Ixodes genus.[3] Usually, the tick must be attached for 36 to 48 hours before the bacteria can spread.[4] In North America, the only

Borrelia burgdorferi is brought in through the tick bite to the bloodstream. From there, it

“Borrelia burgdorferi, the bacterium that causes Lyme disease, was first isolated in 1982 by Willy Burgdorfer, Ph.D., a zoologist and microbiologist at NIAID’s Rocky Mountain Laboratories (RML) in Hamilton, Montana.” (NIAID, 2008.) Dr. Burgdorfer at the time was studying Rocky Mountain Fever in attempt to help Jorge Benach, Ph.D., discover why more than 100 spotted fever cases occurred in New York between 1971 and 1976. “Dr. Benach, of the New York State Department of Health had been a source of American dog ticks for Burgdorfer to study.” (NIAID, 2008.)

Lyme disease is a bacterial infection caused by a spirochete, a corkscrew-shaped bacterium called Borrelia burgodorferi. Lyme disease is primarily transmitted through tick bites, there has been no reported cases of human to human transfer of Lyme disease. Ixodes ticks, also known as deer ticks are the typical carriers of the Lyme disease. The ticks can most primarily be found in wooded and grassy areas. Due to the fact these ticks are only the size of a poppy seed they usually go undetected when they bite. Once the tick is attached to the skin it can feed for several days; the longer the tick is attached the more likely Lyme disease will be transmitted. Lyme disease can affect any organ of the body including the brain, nervous system, muscles, joints, and even the heart. In some cases, if a pregnant woman develops Lyme disease it can pass on to the unborn child and in some cases stillbirth has occurred due to the disease.

Lyme disease is carried by deer ticks. They feed on mice and other rodents. The adults feed mostly on white-tailed deer. When deer ticks bite a human, they can transmit Lyme.

A well-known disease in the United States is Lyme disease. Lyme disease is a bacterial infection transmitted by deer ticks that are infected with the Borrelia burgdorferi bacteria. In the early 1970s a group of children and adults in Lyme, Connecticut, and the surrounding areas were suffering from some puzzling and debilitating health issues. Finally, by the mid-70s, researchers began describing the signs and symptoms of this new disease. They called it Lyme, but they still didn’t know what caused it (History of Lyme Disease | Bay Area Lyme Foundation. n.d.). In the 1980’s, it was discovered that the bacteria came from deer ticks. Centers for Disease Controls and Prevention estimate that 300,000 people are diagnosed with Lyme disease in
