Detection of Borrelia DNA in tick species collected from vegetation and wild animals in Fukuoka, Japan.

Detection of Borrelia DNA in tick species collected from vegetation and wild animals in Fukuoka, Japan. Jpn J Infect Dis. 2019 Sep 30;: Authors: Nakayama S, Kobayashi T, Nakamura A, Yoshitomi H, Song Y, Ashizuka Y Abstract We surveyed the presence of Borrelia spp. in ticks collected from vegetation by flagging and from wild animals from May 2017 to November 2018 in Fukuoka, located in the northern Kyushu area of Japan. A total of 1,601 ticks were collected and morphologically separated into 9 species: Ixodes turdus, I. ovatus, Amblyomma testudinarium, Haemaphysalis flava, H. formosensis, H. kitaokai, H. longicornis, H. hystricis, and H. megaspinosa. The ticks were segregated into 561 pools and nested PCR was used to detect borrelial DNA. Borrelia turdi and Borrelia sp. HM were identified in two of the 561 pools. This is the first report on the presence of Lyme diseases group of Borrelia and Relapsing fever group of Borrelia in Fukuoka. PMID: 31564692 [PubMed - as supplied by publisher]

Conclusions: In Slovenia, LNB in children is more often caused by B. garinii, followed by B. afzelii. The clinical picture of LNB in children caused by B. garinii is not more often suggestive of CNS involvement, but CNS inflammation is more pronounced in children infected with B. garinii, compared with children infected with B. afzelii.

This study documents a high prevalence in ticks of Rickettsia spp. thought to be endosymbionts, a low prevalence of relapsing fever group Borrelia in ticks, and a lack of detection of Lyme disease-group Borrelia in both ticks and mammals in an east Texas forested recreation area. Additionally, we observed low questing tick density in areas with a history of controlled burns. These results expand knowledge of tick-borne disease ecology in east Texas which can aid in directing future investigative, modeling, and management efforts.

Rosales Rizzo, Ying Bai, Michael L. Levin, Rebecca J. Eisen, Lars EisenAbstractThe invasive, human-biting Asian longhorned tick, Haemaphysalis longicornis, was detected in New Jersey in the eastern United States in August of 2017 and by November of 2018 this tick had been recorded from 45 counties across 9 states, primarily along the Eastern Seaboard. The establishment of H. longicornis in the United States has raised the ques...

CONCLUSION: Different specific molecules of the vector, pathogen and host result in LNB establishment. After B. burgdorferi species penetrate host skin through a tick bite, they are confronted by the immune defenses of the host. However, they are helped by specific proteins in different interactions, and the disease is established. The interactions between the vector, pathogen and host are shown in Table 1 and Figure 1. Knowledge of these molecular interactions can aid development of therapeutics against LNB and LD. Others: We systematically describe the different molecular tick-pathogen-host interactions.

H, Heylen D Abstract Wild birds are frequently exposed to the zoonotic tick-borne bacteria Borrelia burgdorferi sensu lato (s.l.), and some bird species act as reservoirs for some Borrelia genospecies. Studying the tropism of Borrelia in the host, how it is sequestered in different organs, and whether it is maintained in circulation and/or in the host's skin is important to understand pathogenicity, infectivity to vector ticks and reservoir competency.We evaluated tissue dissemination of Borrelia in blackbirds (Turdus merula) and great tits (Parus major), naturally and experimentally infected with Borrelia genospe...

Discussion Lyme disease (LD) is caused by several genospecies of Borrelia burgdorferi senu lato that are transmitted by ticks of the Ixodes ricinus complex. In the U.S. and Europe it is the most common vector-borne disease. It is named for Lyme, Connecticut in the 1970s when it was “discovered,” but there are reports of LD-type disease in Europe since 1883. There are 18 distinct genospecies with B. afzelii, B. garinii and B. burgdorferi sensu stricto being the 3 most common ones causing human infection. There are many species of Ixodes ticks but only 4 commonly bite humans. Ixodes ricinus mainly in Europe, I, p...

In 1975, researchers from Yale investigated an epidemic of 51 patients with arthritis who lived near the woodsy town of Lyme, Connecticut. The most common symptom was recurrent attacks of knee swelling. A few had pain in other joints, such as the wrist or ankle. Many had fever, fatigue, and headache. Some remembered a round skin rash before the onset of knee swelling. We now know that Lyme disease is an infection acquired from tick bites, caused by a spiral bacterium named Borrelia burgdorferi. After a tick bite, Borrelia bacteria wriggle through the skin away from the bite site. This leads to a circular red rash, known as...
