Transmission of Lyme Disease

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 can affect nearly all of our body’s functions in one way or another. According to Lyme expert Dr. Lee Cowden, “Typically, the elimination organs are invaded: Kidneys, bladder, liver, skin and lymph glands. The Borrelia

Recent research results suggest that ticks must remain attached to a human for 36-48 hours to efficiently transmit B. burgdorferi so early recognition and removal can be effective in preventing Lyme disease (Cook, 2015). Thus, nymphs represent the greatest risk for infection and have been implicated as the vector in the majority of Lyme disease cases in the United States. Although adults can transmit the disease, nymphs, which are about the size of a poppy seed, are relatively undetectable and significantly less likely to be removed within 48 hours of attachment. As a result, most new cases of Lyme disease occur in the summer months between May and August when nymph activity reaches its peak (Marques,

I chose to do my research paper on Lyme disease. During my research, I found a lot of interesting facts about Lyme disease. The disease is caused by bacteria, called Borrelia burgdorferi, which is only transmitted to humans when they are bitten by an infected tick. Lyme disease was first discovered in 1975, in Lyme, Connecticut, after a group of children were diagnosed with juvenile rheumatoid arthritis. This eventually led them to discover the bacteria Borrelia burgdorferi. The disease was given its name in 1982, after the town of Lyme, Connecticut. According to Center for Disease Control and Prevention, Lyme disease is the most commonly reported vectorborne illness in the United States. In 2014, it was the fifth most common Nationally Notifiable disease. Lyme disease is most prevalent in the northeast and upper Midwest.

No. There is a multitude of animals that can be infected by Lyme disease including dogs, horses, cattle, etc. but only ticks can spread the infection (Burgdorfer, Barbour, Hayes, Benach, Grunwaldt, & Davis, 1982).

The bite of an infected tick is the primary mode of transmission to humans, or other vertebrate hosts, though it is also possible, but extremely rare for infection to result from exposure to crushed tick tissues, fluids, or feces. (http://www.cdc.gov/ncidod/dvrd/rmsf/Natural_Hx.htm)

POWASSAN VIRUS: POTENTIALLY FATAL TICK DISEASE THAT CAN BE TRANSMITTED IN MINUTES REPORTED IN MAINE

The disease was caused by rats and rat fleas but, also from human to human by breathing the same air. Scientists know that the bacillus travels from person to person, through

The most common way this disease is transmitted from one animal to the next is through mosquitoes. A mosquito carrying infective heartworm larvae bites a dog and transmits the infection to them. The larvae grow, develop, and migrate in the body over a period of 6 to 7 months, in which time they become sexually mature male and female worms. this is the prepatent period. The worms then reside in the heart, lungs, and associated blood vessels. The worms begin to mate and release microfilaria into the blood

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)

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

Lyme borreliosis or Lyme disease can be devastating both physically and mentally for victims. The disease is transmitted by a vector, specifically a tick, which infects their host by biting and infecting them with pathological spirochete bacteria known as Borrelia burgdorferi (Muschart & Blommaert, 2015). There are several species of Borrelia globally, and as a group, the bacteria are referred to as Borrelia burgdorferi sensu lato (Pearson, 2015). The disease originated from, Lyme Connecticut, of which it was named, after a patient was mistakenly diagnosed with rheumatoid arthritis when the cause of their disease was B. burgdorferi or Lyme disease (Snow, 2013). Lyme disease is classified as one of the most common and growing vector-born disease in the United States as well as Europe (Snow, 2013). Understanding how Lyme disease progresses through the body as well as the disease’s signs and symptoms are essential to understanding how to treat the disease and stop it from spreading throughout the body with destructive results. With a disease as potentially devastating as Lyme disease, early treatment is required for a better outcome (Pearson, 2015). This research paper will discuss the pathophysiology of three Lyme conditions known as Lyme arthritis, Lyme neuroborreliosis, and Lyme carditis and provide an overview of the signs and symptoms of Lyme disease and treatments, and how to prevent infection.

Bubonic plague is an infectious disease that is spread by the bacteria Yersinia pestis. These bacteria remain in a dormant state primarily in a rat flea’s foregut. Once the flea has bitten a victim it regurgitates the contents in its foregut into the bite location. Once the bacterium has entered into a mammal’s warm body it begins to reproduce and spread throughout the mammal’s body. The reproduction of this bacterium creates large painful swollen lymph nodes which are called buboes. Once these buboes get large enough they begin to ooze infected body fluid so that any contact between an infected person and a healthy person will facilitate the spread of this disease. (The Mayo Clinic Staff, 2012)

How the disease was transmitted was further looked on by Nelson (1995). According to the said author, the disease was transmitted primarily by fleas and rats. The stomachs of the fleas were infected with bacteria known Y. Pestis. Nelson held that “the bacteria would block the "throat" of infected fleas so that no blood could reach their stomachs, and they grew ravenous since they were starving to death” (1995, par. 14). The bacteria would then attempt to suck up blood from their victims, only to disgorge it back into their preys' bloodstreams (Nelson, 1995). Now, however, the victims' blood was mixed with Y. Pestis. Fleas infected rats in this fashion, and the rats spread the disease to other rats and fleas before dying (Nelson, 1995). Without rodent hosts, the fleas then migrated to the bodies of humans and infected them in the same fashion as they had the rats .

Biological transmission occurs when the pathogen reproduces within a biological vector that transmits the pathogen from one host to another . Arthropods are the main vectors responsible for biological transmission. For example, hemipterans (called “kissing bugs” or “assassin bugs”) transmit Chagas disease to humans by defecating when they bite, after which the hu-man scratches or rubs the infected feces into a mucous membrane or break in the
