October Research Updates

Transmission, microbiomes and repellents

There’s a definite chill in the air these days, but it serves as an excellent reminder that we need to be vigilant about the blacklegged ticks that are active this time of year, making tick checks essential after spending any time out in the greenery.

My latest search of scientific journals turned up a handful from this year that hadn’t yet made it into my database. The addition of these latest papers brings the total number of Canadian-authored research papers on the Lyme Disease in Canada site to 314 and counting.

Here’s what I’ve added to the 2019 list:

Prevention of transfusion-transmitted infections

Detection of 'Candidatus Ehrlichia khabarensis' in rodents and ticks removed from rodents in British Columbia, Canada

Sex-Specific Linkages Between Taxonomic and Functional Profiles of Tick Gut Microbiomes

What is your diagnosis? A feline blood smear

Pharmacokinetics of imidocarb dipropionate in white‐tailed deer (Odocoileus virginianus) after single intramuscular administration

Critical diapause portion for oscillations: Parametric trigonometric functions and their applications for Hopf bifurcation analyses

Behavioral responses of Ixodes scapularis tick to natural products: development of novel repellents

Maternal antibodies provide strain-specific protection against infection with the Lyme disease pathogen in bank voles


In addition to the papers I’ve added for this year, I’ve also added some historical ones (historical = pre-2019) that got missed when I was indexing papers in previous years. It’s amazing how many of these turn up despite what I thought were thorough searches at the time.

Here’s what I’ve added:
