UMass Amherst tick testing lab joins national ecology tracking project

(University of Massachusetts at Amherst) The LMZ at UMass Amherst earned a two-year, renewable contract for up to $112,000 per year to test several thousand ticks for six bacterial and one protozoan pathogen using DNA-based assays. UMass Amherst microbiology professor and LMZ director Stephen Rich says these tests will detect the pathogens that cause Lyme disease, Anaplasmosis and Babesiosis, among others.

Abstract Ticks are the most important vectors of human pathogens, leading to increased public health burdens worldwide. Tick-borne pathogens include viruses (e.g. tick-borne encephalitis and Powassan); bacteria, such as the causative agents of Lyme disease, spotted fever rickettsiosis and human anaplasmosis; and malaria-like protozoan parasites causing babesiosis. Tick-borne diseases are emerging due to the geographical expansion of their tick vectors, especially in the northern hemisphere. Two examples of this phenomenon are Ixodes scapularis and Amblyomma americanum, which have expanded their ranges in the USA i...

Committee Opinion No. 399: Management of Tick Bites and Lyme Disease During Pregnancy: (En français : Prise en charge des morsures de tiques et de la maladie de Lyme pendant la grossesse). J Obstet Gynaecol Can. 2020 May;42(5):644-653 Authors: Smith GN, Moore KM, Hatchette TF, Nicholson J, Bowie W, Langley JM Abstract OBJECTIVE: Lyme disease is an emerging infection in Canada caused by the bacterium belonging to the Borrelia burgdorferi sensu lato species complex, which is transmitted via the bite of an infected blacklegged tick. Populations of blacklegged ticks continue to expand and are now es...

Abstract Tickborne diseases that affect patients in the United States include Lyme disease, Rocky Mountain spotted fever (RMSF), ehrlichiosis, anaplasmosis, babesiosis, tularemia, Colorado tick fever, and tickborne relapsing fever. Tickborne diseases are increasing in incidence and should be suspected in patients presenting with flulike symptoms during the spring and summer months. Prompt diagnosis and treatment can prevent complications and death. Location of exposure, identification of the specific tick vector, and evaluation of rash, if present, help identify the specific disease. Lyme disease presents with an ...

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...

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.

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...

AUGUSTA, Maine (AP) — Maine reported a record number of Lyme disease cases last year, and the number could rise as data continues to trickle in, officials said Thursday. There were at least 2,079 cases in 2019, the Maine Center for Disease Control and Prevention reported. It’s too early to say why the numbers grew last year. But the numbers underscore the importance of taking precautions to avoid tick bites, said Dr. Nirav Shah, director of the Maine CDC. Winter is a time of low ticket activity. But ticks can be active when the temperature climbs above 40, as it did last weekend in Maine. The state also experie...

CONCLUSIONS: Of the ten ticks infected with B. burgdorferi s. l., B. afzelii was found in seven, undefinied genospecies in two, and mixed infection with B. afzelii and B. burgdorferi s. s. in one. The study demonstrated the potential risk of exposure of humans and animals to infections of B. burgdorferi s. l., A. phagocytophilum and B. microti in the examined area of Poland.
