Anaplasmataceae, Borrelia and Hepatozoon agents in ticks (Acari: Argasidae, Ixodidae) from Chile.

Anaplasmataceae, Borrelia and Hepatozoon agents in ticks (Acari: Argasidae, Ixodidae) from Chile. Acta Trop. 2019 Feb 05;: Authors: Muñoz-Leal S, Lopes MG, Marcili A, Martins TF, González-Acuña D, Labruna MB Abstract Microorganisms harbored by Chilean autochthonous ticks have been scarcely studied and current knowledge is restricted to three species of hard ticks only. The current study aimed to assess the presence of Anaplasmataceae, Borrelia and Hepatozoon agents in ticks collected directly from the environment, on reptiles, birds and mammals in twelve localities from northern, central and southern regions of the country and Antarctica. Ticks were identified by means of a morphological and molecular approach. PCR detections point the occurrence of an Anaplasma-like agent and a relapsing fever Borrelia sp. in Ornithodoros spheniscus; an Ehrlichia sp. and a Hepatozoon sp. in Ornithodoros atacamensis; "Candidatus Neoehrlichia chilensis", Borrelia burgdorferi sensu lato (s. l.), and Hepatozoon in Ixodes ticks morphologically related to the Ixodes sigelos group; and B. burgdorferi s. l. in Ixodes auritulus. Supported by phylogenetic analyses of characterized microorganisms, this study introduces putative vector roles and initial evidence on possible new agents detected in Chilean ticks.

Conclusion: This study was the first to determine the frequency of hantavirus in the study region and it includes current data for B. burgdorferi. Consequently, it is recommended that similar studies be carried out on rodents in all the regions at risk. PMID: 30862151 [PubMed - as supplied by publisher]

(Natural News) If you spend any amount of time outdoors or around animals, you’re at risk of Lyme disease. This infectious disease is transmitted by ticks, but it’s actually caused by a microbe, the Borrelia burgdorferi sensu lato bacteria. While many prevention methods focus on the ticks themselves, some researchers are looking into antimicrobial herbs...

Authors: Weiss T, Zhu P, White H, Posner M, Wickiser JK, Washington MA, Barnhill J Abstract Lyme disease is a continuing threat to military personnel operating in arboriferous and mountainous environments. Here we present the case of a 24-year-old Second Lieutenant, a recent graduate from the United States Military Academy, with a history of Lyme disease who developed recurrent knee effusions following surgery to correct a hip impingement. Although gonococcal arthritis was initially suspected from preliminary laboratory results, a comprehensive evaluation contradicted this diagnosis. Despite antibiotic therapy, asp...

CONCLUSION: It should be noted that detection of antibodies against B. burgdorferi s.l. is only an indirect evidence of the presence of this bacterium in the development of clinical signs of LD in humans. Laboratory LD tests should be performed in accordance with valid standards, positive and uncertain results must be confirmed by the Western Blot/Immunoblot assay. PMID: 30817877 [PubMed - in process]

CONCLUSION: The results of seroprevalence obtained in the present study confirm the possibility of infection with B. burgdorferi among respondents exposed to contact with ticks. PMID: 30817876 [PubMed - in process]

This pathogen has not yet been described in humans. Data are lacking on the role of migratory birds in the adventitious spread of Ba. odocoilei-infected ticks, as well as on the infection status of I. scapularis in ...

Bockenstedt, Jean I. TsaoAbstractBorrelia miyamotoi is a relapsing fever spirochete transmitted by ticks in the Ixodes ricinus complex. In the eastern United States, B. miyamotoi is transmitted by I. scapularis, which also vectors several other pathogens including B. burgdorferi sensu stricto. In contrast to Lyme borreliae, B. miyamotoi can be transmitted vertically from infected female ticks to their progeny. Therefore, in addition to nymphs a...

Borrelia miyamotoi disease (BMD) is a newly recognized borreliosis that is cotransmitted by ticks wherever Lyme disease is zoonotic. Unlike Borrelia burgdorferi sensu lato, the agent of Lyme disease, B. miyamotoi is closely related to relapsing fever spirochetes, such as Borrelia hermsii. Some authors have suggested that the disease caused by B. miyamotoi should be considered a hard-tick-transmitted relapsing fever, and thus, the main mode of confirming a diagnosis for that infection, microscopy to analyze a blood smear, may have clinical utility. To determine whether blood smears may detect B. miyamotoi in the blood of ac...
