    Substantial health threat: Never-before-seen tick-borne disease

    Now, just in time for spring and the explosion of ticks in forests, lawns and trails, a new study by researchers from China and the University of Maryland School of Medicine (UM SOM) has uncovered a never-before-seen illness transmitted by ticks. It's possible that the disease could be a "substantial health threat" to humans and animals in areas where the carrier tick is common, the authors write in the paper.

    J. Stephen Dumler, MD, a professor of pathology at the school, helped identify the newly discovered bacterial species, which the researchers named Anaplasma capra. The paper was published in the latest issue of the journal Lancet Infectious Disease.

    "This is an entirely new species of bacteria," said Dr. Dumler, an expert on tick-borne diseases who has worked all over the world. "This had never been seen in humans before. We still have a lot to learn about this species, but it may be that this bacteria is infecting humans over a wide area." He collaborated on the paper with scientists at several Chinese institutions: the Beijing Institute of Microbiology and Epidemiology, the Mudanjiang Forestry Central Hospital, and the Shanghai Institute of Medical Genetics at Shanghai Jiaotong University. The lead author of the study was Wu-Chun Cao, MD, PhD, of the Beijing Institute.

    The researchers tested 477 patients in northeastern China who had been bitten by a tick over a month-long period in the spring of 2014. Of those, 28, six percent, were found to have been infected by the new species of bacteria. This microbe is related to other Anaplasma bacteria, some of which can cause illness when transmitted from ticks to humans. Dr. Dumler himself discovered one such disease, human anaplasmosis, two decades ago.

    The symptoms of A capra infection include fever, headache, and tiredness, dizziness and muscle aches. The researchers successfully treated the infection with antibiotics, particularly doxycycline.

    Because no one knew the bacteria existed, no one has looked for it, and it is not clear how widespread it is. In China, the species appears to be common in goats -- the researchers decided to call it "capra" because the word means "goat" in Latin. But it may also infect other animals. Currently, it is difficult to diagnose infection -- there is no simple blood test.

    The bacterium is probably transmitted via a tick species known as the taiga tick. This species, which is closely related to the deer tick, lives in Eastern Europe and across Russia and Asia, including China and Japan. If this tick species transmits A capra throughout this area, human infection may be common. Dumler notes that about a fifth of the world's population, more than a billion people, live in areas where the tick resides.

    "Dr. Dumler continues to distinguish himself as an international leader in scientific discovery related to tick-borne illnesses," said Dean E. Albert Reece, MD, PhD, MBA, who is also the vice president for Medical Affairs, University of Maryland, and the John Z. and Akiko K. Bowers Distinguished Professor and Dean of the School of Medicine. "As we understand more about these diseases, we are able to better address this growing international public health problem, as we have begun to do with Dr. Dumler's previous discoveries."

    Dr. Richard Horowitz:

    • A study from researchers from China and the University of Maryland has discovered a new tick-borne infection. Dr Stephen Dumler, MD, helped identify the new bacterial species, called Anaplasma capra. "The symptoms of A capra infection include fever, headache, and tiredness, dizziness and muscle aches (similar to other Anaplasma infections)....Because no one knew the bacteria existed, no one has looked for it, and it is not clear how widespread it is. The researchers successfully treated the infection with antibiotics, particularly doxycycline."

      !! The discovery of this new bacteria is part of a growing international problem with ticks and emerging infections. In the last decade, we have seen an increase in the number of new bacterial infections in ticks, such as Borrelia miyamotoi, and other relapsing fever bacteria, like Borrelia bissettii. Borrelia miyamotoi was discovered in up to 4% of New England residents (NEJM), and B. bissettii was recently implicated as a human pathogen in Mendocino County, California (Girard YA, Fedorova N, Lane RS. Genetic diversity of Borrelia burgdorferi and detection of B. bissettii-like DNA in serum of north-coastal California residents. J Clin Microbiol. 2011;49:945–54). Overall, there has been a worldwide increase in the incidence of new Borrelia infections in the last 10 years, with 15 new species (1990-2010). These species include in the USA: B. burgdorferi sensu strictu, Borrelia sensu latu, and Borrelia kurtenbachii species; in Europe: Borrelia afzelii (ACA), Borrelia garinii (neuroborreliosis), B. spielmani (early skin disease), B. valaisana, B. lusitanea, and B. bavariensis; in Asia, B. japonica, B. turdi, B. tanukii, B.yangtze; in North America, Borrelia andersonii; in the southern U.S, B. americanum, and B. carolinensis; and in the Pacific U.S, B. bissettii. We have also seen an expansion of viral infections in ticks in the last few years, such as the recently discovered Heartland and Bourbon viruses, and Powassan virus.

      This new Anaplasma species joins the tick-transmitted bacteria of the genera Neorickettsia, Anaplasma, and Ehrlichia. Ehrlichiosis includes HSE (N. sennetsu), HGA (A. phagocytophilum), HME (E. chaffeensis), HEE (E. ewingii) and HWME (E. Wisconsin-Minn), As is the case with Anaplasma capra, there are no specific tests for all of these species (i.e.,E. ewingii: Human Babesiosis and Ehrlichiosis-Current Status. Shah, J., Horowitz, R., Eur Infect Dis, Vol 6, Issue 1, Spring 2012), so patients may become ill without an apparent etiology . Anaplasma species may also be transmitted by blood transfusion (Annen, K., et al. Two cases of Transfusion-Transmitted Anaplasma phagocytophilum. American Journal of Clinical Pathology. 2012 Apr;137(4):562-5). It is therefore imperative that our surveillance efforts for tick-borne diseases include regularly testing ticks for novel infections, both in the US and worldwide, as the number and type of these infections is rapidly expanding.

    Почему-то думается, что это не последнее открытие в этой области.)

    @СергейСк -может вам взять на заметку где занимаются в Китае подобными инфекциями?

    Chinese institutions: the Beijing Institute of Microbiology and Epidemiology, the Mudanjiang Forestry Central Hospital, and the Shanghai Institute of Medical Genetics at Shanghai Jiaotong University. The lead author of the study was Wu-Chun Cao, MD, PhD, of the Beijing Institute

    Вот эти ребята еще год назад рассмотрели мои анализы и подробнейшую историю болезни и заявили, что лаймом тут не пахнет:)

    Подруга знакомого там работает, тогда, еще в самом начале, он мне предложил вот такую вот "заочную диагностику". Сама бы я, конечно, про Китай не подумала)) я им все сканировала, написала огромную, подробную историю болезни - мне сообщили, что надо думать в сторону аутоиммунного)

    Галина, здравствуйте... Как то так вышло что я этого сообщения не видел ( Там Шанхай я смотрю тоже есть, в четверг все узнаю обязательно! Может они действительно что то подскажут..... Хотя зная их немного (
