THE CONVERSATION 13/05/20 How the Lyme disease epidemic is spreading and why ticks are so hard to stop. In the 1970s, an epidemic of mysterious arthritis-like symptoms began spreading among children in the lushly wooded area around Lyme, Connecticut.
Scientists traced the cause to tick bites and named it Lyme disease, but why it had suddenly appeared there was a mystery. Similar symptoms had been documented on Long Island, New York, years before. Doctors there called it “Montauk spider bite” or “Montauk knee.” Duke's Nicholas School of the Environment VIA YOUTUBE 28/12/10 The Function of Biodiversity in Zoonotic Disease Risk: The Cases of Lyme Disease and West Nile Virus.

Estimation of cognitive and affective disorders occurrence in patients with Lyme borreliosis Introduction and objective:Lyme borreliosis (LB) is a disease caused by the bacteria Borrelia burgdorferi.
The most common symptoms are related to the skin, musculo-scelatal system, central and peripheral nervous system, rarely to the heart muscle and the eye, and may occur in the multistage course of the disease. LB may additionally be accompanied by psychopathological symptoms. The aim of the study is estimation of the cognitive and affective disorders occurence in patients with LB. Material and Methods:The study was carried out in the group of 121 patients (61 females, 60 males) aged 18–65; mean age 46 years. Results:Cognitive disorders occurred statistically significantly more often in patients with neuroborreliosis (14.7%) than in patients with Lyme arthritis (4.3%).

BMC PUBLIC HEALTH 25/11/17 Social-cognitive determinants of the tick check: a cross-sectional study on self-protective behavior in combatting Lyme disease. Lyme disease, also known as Lyme borreliosis, is the most prevalent tick-borne disease in Europe.
It is primarily transmitted through a bite from a tick that is infected with the Borrelia burgdorferi bacteria . When left untreated, Lyme disease may cause severe and potentially chronic symptoms such as neurological diseases, joint problems, and heart diseases . Both societal and scientific issues call for further research to build effective public health programs to prevent Lyme disease. The first societal issue is the sharp increase in the incidence of tick bites and tick-borne diseases [3, 4]. As an example from the Netherlands, in 1994, 191 per 100,000 Dutch inhabitants visited their GP concerning a tick bite; a number that had risen to 488 per 100,000 inhabitants in 2014, although this now seems to stabilize .
A systematic perusal of the literature1 reveals three issues in this field of study that may hamper the development of effective interventions. Parasites & Vectors 16/12/16 Comparison of the lifetime host-to-tick transmission between two strains of the Lyme disease pathogen Borrelia afzelii. The results of our study were consistent with the boom-and-bust model of host-to-tick transmission proposed by Kurtenbach et al. .
For strains A3 and A10, host-to-tick transmission was highest (75.0 and 90.8%, respectively; Table 1) at the end of the acute phase of the infection (day 34 PI), followed by a plateau of lower (but still high) transmission (62.9 and 64.2%, respectively; Table 1) over the chronic phase of the infection (days 66, 94 and 128 days PI). The reduction in the efficiency of systemic transmission between the acute and chronic phase of the infection was 16.1 and 29.3% for strains A3 and A10, respectively. Our results are similar to an earlier experimental infection study of B. afzelii in the wood mouse, Apodemus sylvaticus . Dr. Joyce Harman VIA YOUTUBE 28/09/16 Lyme Disease in the Equine, Part II.

PHYSORG 25/08/16 How Lyme disease bacteria spread through the body. Researchers have developed a live-cell-imaging-based system that provides molecular and biomechanical insights into how Lyme disease bacteria latch onto and move along the inside surface of blood vessels to reach key destinations in the body where they may be able to persist longer and avoid treatment.
Ironically, the same strategies that these bacteria use to spread through the body are also used by immune cells to protect against infectious disease. The study appears August 25 in Cell Reports. "There is very little known about the biomechanics of bacterial-vascular interactions, even though understanding this is really important for understanding how bacteria spread through the body via the cardiovascular system, and for developing methods to block bacterial dissemination," says senior study author Tara Moriarty of the University of Toronto.

Introduction In North America, Lyme disease is most often caused by Borrelia burgdorferi sensu stricto . According to the guidelines of the Centers for Disease Control and Prevention (CDC), its diagnosis is primarily based on symptoms, physical findings (e.g., rash), and the possibility of exposure to infected ticks; laboratory testing is helpful if used correctly and performed with validated methods . However, the clinical manifestations of Lyme disease are highly variable and often not easily distinguished from those caused by other illnesses in clinical practice . The characteristic erythema migrans (EM) rash may not display a classic bull’s-eye (ring-within-a-ring) appearance, a fact that may be underappreciated.
Although initially described as a joint disease , Lyme disease is actually a systemic infection presenting with bacteremia at some point during the course of the disease [6–9]. 2. 2.1.

An international team of scientists led by Purdue University has sequenced the genome of the tick that transmits Lyme disease, the most common vector-borne illness in North America. Ixodes scapularis, known as the blacklegged tick or the deer tick, is the first tick species to have its genome sequenced. NATURE 09/02/16 Genomic insights into the Ixodes scapularis tick vector of Lyme disease.

CDC 02/11/15 Borrelia mayonii. In 2013, scientists at the Mayo Clinic noticed an unusual result while testing blood from patients suspected of having Lyme disease. Cooperation between Mayo Clinic, state public health agencies, and CDC confirmed the discovery as a new bacterial species, also found in blacklegged ticks. Joint efforts between these groups are currently underway to find more patients infected with this bacteria, to look for additional areas where infected ticks live, and to identify other bacteria that cause tickborne disease.
What is Borrelia mayonii? Borrelia mayonii is the proposed name for a new bacteria species recently found to cause Lyme disease in six people who live in the upper Midwestern United States.

Female adult Ixodes spp. ticks are believed to be primarily responsible for transmitting B. burgdorferi to horses.
Photo: James Gathany/Centers for Disease Control Lyme disease in North America is caused by the bacteria Borrelia burgdorferi sensu stricto. B. burgdorferi survives in a small rodent and Ixodes spp. tick cycle. Horses and many other mammals can become infected during tick feeding. Generally, 24 to 48 hours of attachment are required to transfer B. burgdorferi from the tick to the mammalian host. Female adult Ixodes spp. ticks are believed to be primarily responsible for transmitting B. burgdorferi to horses, while in humans the smaller and harder to see nymphs are responsible for more infections. B. burgdorferi infection in horses is common in several areas of North America. A wide variety of clinical signs have been attributed to B. burgdorferi infection in horses, but cause and effect have been difficult to document in most cases.

By Hannah Foster Upon hearing the words “Lyme disease,” most people think of two things: ticks and deer. Although these are certainly important aspects of the disease, ticks and deer are only two pieces of the puzzle. Lyme disease is actually extremely complicated, and its spread is affected by a wide range of organisms. Knowing the full story is important for individuals to protect themselves, and it’s necessary for scientists and epidemiologists to determine how to control the disease.
