“As far as we are aware, we are writing the first report of Plasmodium spp. and Borrelia burgdorferi co‐infection (a co‐infection of a tropical parasite and a non-tropical bacterium),” explains Neves from the Infectious Diseases Department, Centro Hospitalar São João, Portugal. The man had returned to Portugal from Angola, where he worked as a welder. […]

Twenty-five of the 26 acute care hospitals participated. According to Daly from the Bureau of Infectious Disease Control, New Hampshire Department of Health and Human Services, “6% and 22%

Cameron, MD MPH The article describes a 55-year-old patient with a 2-month history of chronic neck pain with progressive marked asthenia. “Clinical examination revealed a dysarthria which disappeared in less than 1 hour, a left upper limb cerebellar ataxia and a bilateral asymmetric mild akineto-hypertonic parkinsonism,” according to Pische´ from the Department

“This study demonstrates that image-based tick identification may be an accurate and useful method of detecting ticks for surveillance when images are of suitable quality,” explains Koffi from the Centre for Foodborne Environmental and Zoonotics Infectious Diseases, Public Health Agency of Canada. Forty-one veterinary clinics located throughout regions of Quebec submitted digital images of ticks

“A previously healthy Caucasian 22-year-old male presented to a southern Quebec community hospital with syncopal episodes for one week,” according to Samuel De l’Étoile-Morel from the Department of Internal Medicine, McGill University Health Centre. “He was found to be hypotensive and bradycardic (heart rate 36 beats per minute), due to 3rd degree atrio-ventricular (AV) block,

The test requires that positive or equivocal ELISA tests be confirmed with 2 of 3 IgM bands or 5 of 10 IgG bands. The western blot based TTT has been considered sensitive for

The authors identified, from an FDA drug library and an NCI compound library, three sulfa drugs and trimethoprim for study. “Dapsone, sulfachlorpyridazine and trimethoprim showed very similar activity against stationary phase B. burgdorferi enriched in persisters; however, sulfamethoxazole was the least active drug among the three sulfa drugs tested.” [1] Combinations of antibiotics were more

Cameron, MD MPH The patient presented with a syncopal episode with no prodrome, shortness of breath and weakness, according to the case study, entitled Electrocardiographic progression of acute Lyme disease. “Three weeks prior to the presentation, he had experienced an “insect bite” on his calf after being outside. A week later, he

Cameron, MD MPH The study entitled “Melting pot of tick-borne zoonoses: the European hedgehog contributes to the maintenance of various tick-borne diseases in natural cycles urban and suburban areas,” investigates the extent to which hedgehogs contribute to the enzootic cycle of tick-borne pathogens. European hedgehogs are urban dwellers and legally protected in

by Daniel J. Cameron, MD MPH The Lyme disease bacterium swims in an undulating pattern throughout the body. “The flagella reside within the periplasm, the space between the bacterial cell wall and the outer membrane,” according to Harman, from the Department of Molecular and Cellular Biology, University of Arizona.
