We describe the only reported cases of peri ocular tick bite from India that presented to us within a span of 3 days and its management. Due suspicion and magnification of the lesions revealed the ticks which otherwise masqueraded as small skin tags/moles on gross examination. The ticks were firmly latched on to the skin and careful removal prevented incarceration of the mouth parts. Rickettsial diseases that were believed to have disappeared from India are reemerging and their presence has recently been documented in at least 11 states in the country. Among vector borne diseases, the most common, Lyme disease, also known ...

This report highlights the continuing public health challenge of Lyme disease in states with high incidence and demonstrates its emergence in neighboring states that previously experienced few cases. Educational efforts should be directed accordingly to facilitate prevention, early diagnosis, and appropriate treatment. As Lyme disease emerges in neighboring states, clinical suspicion of Lyme disease in a patient should be based on local experience rather than incidence cutoffs used for surveillance purposes. A diagnosis of Lyme disease should be considered in patients with compatible clinical signs and a history of potenti...

Abstract The spirochete bacterium Borrelia burgdorferisensu lato is the causative agent of Lyme disease, the most common vector-borne disease in Europe and the United States. The spirochetes can be transmitted to humans via ticks, and then spread to different tissues, leading to arthritis, carditis and neuroborreliosis. Although antibiotics have commonly been used to treat infected individuals, some treated patients do not respond to antibiotics and experience persistent, long-term arthritis. Thus, there is a need to investigate alternative therapeutics against Lyme disease. The spirochete bacterium colonization i...

is the most common tick-borne illness in the USA and Europe. Pathogens involved are Borrelia burgdorferi in the USA and B. afzelii and B. garinii in Europe. The characteristic rash of erythema migrans occurs in approximately 75% of patients. Neurological disease, including facial palsy, meningoencephalitis, aseptic meningitis and polyradiculopathy, occurs in 10 –15%. Cardiac disease, primarily manifest as heart block, is seen in 1–2%. Arthritis is seen as a late complication in about 30%.

In this study, we show that mAb blockade revealed a unique role for IFN-β in Lyme arthritis development in B6.C3-Bbaa1 mice. Genetic control of IFN-β expression was also identified in bone marrow-derived macrophages stimulated with B. burgdorferi, and it was responsible for feed-forward amplification of IFN-stimulated genes. Reciprocal radiation chimeras between B6.C3-Bbaa1 and C57BL/6 mice revealed that arthritis is initiated by radiation-sensitive cells, but orchestrated by radiation-resistant components of joint tissue. Advanced congenic lines were developed to reduce the physical size of the Bbaa1 interval, a...

We report an atypical case of European LCLB, suggesting that ACA is not the only possible presentation of LCLB. The diagnosis of ACA is often clinically missed for months or years, and may be mistaken at the inflammation phase for vascular disorders, erysipelas or bursitis/arthritis, and at the atrophic phase for lichen sclerosus atrophicus, morphoea or anetoderma. To our knowledge, no such tumorous LCLB has previously been described.

Publication date: October 2017 Source:Microbial Pathogenesis, Volume 111 Author(s): Hua Zhao, Aihua Liu, Yuhui Cui, Zhang Liang, Bingxue Li, Fukai Bao Lyme neuroborreliosis is a nervous system infectious disease caused by Borrelia burgdorferi (B. burgdorferi). It has been demonstrated that cytokines induced by B. burgdorferi are related to Lyme neuroborreliosis. Microglia is known as a key player in the immune responses that occur within the central nervous system. In response to inflammation, it will be activated and generate cytokines and chemokines. Experiments in vitro cells have showed that B. Burgdorf...

Abstract Borrelia burgdorferi (Bb) is the causative agent of Lyme disease in the US, a disease that can result in carditis, and chronic and debilitating arthritis and/or neurologic symptoms if left untreated. Bb survives in the midgut of the Ixodes scapularis tick, or within tissues of immunocompetent hosts. In the early stages of infection, the bacteria are present in the bloodstream where they must resist clearance by the innate immune system of the host. We have found a novel role for OspC from B. burgdorferi and B. garinii in interactions with the complement component C4b and bloodstream survival in vivo. Our data show...

Ticks and the diseases they carry have long been recognized as health concerns, especially in the warmer months when ticks (and humans) are more active. Ticks wait on grass tips or shrubs to latch onto new hosts when they brush by. Most of the hosts are animals, but a few tick species do bite and feed on humans. While doing so, they can transmit bacteria and viruses through their saliva. But here’s what’s changing: Tick species are being found in a wider geographic range. The number of case reports of tick-borne illnesses is increasing. Scientists continue to identify new pathogens (bacteria and viruses that c...
