ORONO, Maine (AP) — More than a third of the deer ticks submitted to a Maine lab last year tested positive for Lyme disease, a surveillance report from the lab said. The report is from the University of Maine Tick Lab. The lab found that a smaller percentage of ticks tested positive for anaplasmosis and babesiosis, which are other tick-borne diseases. The tick lab’s manager, Griffin Dill, said the information will help authorities learn how fast the ticks are spreading in the state. The study is the first of its kind in Maine, the Bangor Daily news reported. The report found that just shy of 39% of deer ticks t...

Conclusions: The interleukin-6/interleukin-10 ratio can be used as a rapid diagnostic cue upon suspected tick-borne infection, enabling fast and correct treatment. Also, in serology-negative results, such information may strengthen a clinical suspicion.

We report here the validation of a duplex real-time PCR assay using whole blood specimens on the Luminex ARIES® instrument, combining DNA extraction, amplification and detection into a one-step process. This method allows for rapid and sensitive detection of acute infections with Ehrlichia spp. and Anaplasma phagocytophilum using whole blood specimens. We included A. phagocytophilum to monitor emergence of this pathogen in Kentucky, since surrounding states have reported many more cases than Kentucky.

JoostenAbstractChanges in cellular metabolism have proven to be important factors in driving cell behavior. It has been shown that cellular metabolism of immune cells changes when exposed to or infected by several pathogens: while this is often an adaptation of the host cells to the infection, sometimes it represents a mechanism through which the pathogens evade immune activation. Borrelia burgdorferi sensu lato, the causative agent of Lyme borreliosis, is a pathogen that highly depe...

Lyme disease (LD), which is caused by genospecies of the Borrelia burgdorferi sensu lato complex, is the most common vector-borne disease in the Northern hemisphere. Spirochetes are transmitted by Ixodes ticks and maintained in diverse vertebrate animal hosts. Following tick bite, spirochetes initially establish a localized infection in the skin. However, they may also disseminate hematogenously to several distal sites, including heart, joints, or the CNS. Because they need to survive in diverse microenvironments, from tick vector to mammalian hosts, spirochetes have developed multiple strategies to combat the numerous hos...

ConclusionA discriminant analysis was shown to be useful to distinguish the independently most important cytokines/chemokines (CXCL1, GM-CSF, IL-7 and IL-10) in CSF, in order to discriminate LNBtot patients from Non-LNB patients. An IL-10/CXCL1 ratio was shown to have a promising diagnostic profile with a better performance than the chemokine CXCL13 in CSF. However, further evaluation is required to address future possible usefulness of these cytokines and chemokines in laboratory diagnostics in LNB, including control groups with neuro-inflammation. No significant associations were found between CSF immune mediator levels ...

This study investigated Borrelia prevalence and species distribution in ticks removed from humans and sent as diagnostic material to the Institute for Parasitology, University of Veterinary Medicine Hannover, in 2013-2017. A probe-based real-time PCR was carried out and Borrelia-positive samples were subjected to species determination by reverse line blot (RLB), including a B. miyamotoi-specific probe. The overall Borrelia-infection rate as determined by real-time PCR was 20.02 % (510/2547, 95 % CI: 18.48–21.63 %), with annual prevalences ranging from 17.17 % (90/524, 95 % CI: 14.04–20.68 %) in 2014 to 24.12 % ...

Abstract Ixodes scapularis is currently known to transmit 7 pathogens responsible for Lyme disease, anaplasmosis, babesiosis, tick-borne relapsing fever, ehrlichiosis, and Powassan encephalitis. Ixodes scapularis can also be colonized by endosymbiotic bacteria including those in the genus of Rickettsia. We screened 459 I. scapularis ticks submitted to the Connecticut Agricultural Experiment Station Tick Testing Laboratory with the objectives to (1) examine differences in infection prevalence of Borrelia burgdorferi, Anaplasma phagocytophilum, Babesia microti, and Borrelia miyamotoi, (2) evaluate whether prevalence...
