What is a vector involved in the spread of Lyme disease?
Lyme disease, caused by the spirochete Borrelia burgdorferi, is the most common vector-borne illness in the United States. The vector that transmits B. burgdorferi is the deer tick (Ixodes scapularis), an inhabitant of the northeastern, southeastern, and north-central United States.
How is Lyme disease most commonly spread?
Lyme disease is an infection caused by the bacteria Borrelia burgdorferi. This spiral shaped bacterium is most commonly spread by a tick bite.
Is a tick a vector for Lyme disease?
Ticks are effective vectors and, sometimes, effective reservoirs. In some species, adult females can transmit the pathogens to their offspring as a result of transovarial transmission.

What is Lyme disease caused by?
Lyme disease is caused by the bacterium Borrelia burgdorferi and rarely, Borrelia mayonii. It is transmitted to humans through the bite of infected blacklegged ticks.
How is Lyme disease transmitted to humans?
Lyme disease, or borreliosis, is caused by the bacterium Borrelia burgdorferi and is transmitted to humans through the bite of an infected blacklegged deer tick. It is the most common tickborne infectious disease in the United States.
What type of animal vectors are ticks?
Tick Vectors of Lyme Disease. Ticks are arthropods belonging to the class Arachnida, which also includes spiders and scorpions. They are divided into two families: Ixodidae (hard ticks) and Argasidae (soft-bodied ticks).
Are ticks vectors or parasites?
Ticks are important vectors of various pathogenic protozoa, bacteria and viruses that cause serious and life-threatening illnesses in humans and animals worldwide.
What is a biological vector give two examples?
Vectors are frequently arthropods, such as mosquitoes, ticks, flies, fleas and lice. Vectors can transmit infectious diseases either actively or passively: Biological vectors, such as mosquitoes and ticks may carry pathogens that can multiply within their bodies and be delivered to new hosts, usually by biting.
What are the 3 types of Lyme disease?
This broad classification of Lyme-causing Borrelia includes many species and strains of Lyme-causing Borrelia, including:Borrelia burgdorferi sensu stricto. ... Borrelia afzelii. ... Borrelia garinii.
What insects can carry Lyme disease?
The Lyme disease bacterium, Borrelia burgdorferi, is spread through the bite of infected ticks. The blacklegged tick (or deer tick, Ixodes scapularis) spreads the disease in the northeastern, mid-Atlantic, and north-central United States.
What species of animals carry Lyme disease?
What animals get Lyme disease? Dogs, horses and sometimes cattle can get Lyme disease. White-tailed deer, mice, chipmunks, gray squirrels, opossums and raccoons can also be infected.
Why did Lyme disease spread so rapidly?
Long, wet winters, a warmer climate, and more people building homes in rural areas are among the reasons why Lyme disease and other tick-borne illnesses are increasing nationwide, experts say.
Is Lyme disease spread by mosquitoes?
Spirochetes were also detected in 1.7% of mosquito females, 3.2% of larvae and in 1.6% of pupae of Culex pipiens pipiens. The results of the present study confirm that contact with ticks constitutes the main risk of contracting Lyme disease, although mosquitoes play a role as vectors as well.
How long before Lyme disease is transmitted?
Even if a tick is attached, it must have taken a blood meal to transmit Lyme disease. At least 36 to 48 hours of feeding is typically required for a tick to have fed and then transmit the bacterium that causes Lyme disease.
Where does Lyme disease bacteria live?
These tiny arachnids are typically found in wooded and grassy areas. Although people may think of Lyme as an East Coast disease, it is found throughout the United States, as well as in more than sixty other countries.
