Spatio-temporal variation in environmental features predicts the distribution and abundance of Ixodes scapularis.

Spatio-temporal variation in environmental features predicts the distribution and abundance of Ixodes scapularis. Int J Parasitol. 2020 Dec 23;: Authors: Tran T, Prusinski MA, White JL, Falco RC, Vinci V, Gall WK, Tober K, Oliver J, Sporn LA, Meehan L, Banker E, Backenson PB, Jensen ST, Brisson D Abstract Many species have experienced dramatic changes in both geographic range and population sizes in recent history. Increases in the geographic range or population size of disease vectors have public health relevance as these increases often precipitate the emergence of infectious diseases in human populations. Accurately identifying environmental factors affecting the biogeographic patterns of vector species is a long-standing analytical challenge, stemming from a paucity of data capturing periods of rapid changes in vector demographics. We systematically investigated the occurrence and abundance of nymphal Ixodes scapularis ticks at 532 sampling locations throughout New York State (NY), USA, between 2008 and 2018, a time frame that encompasses the emergence of diseases vectored by these ticks. Analyses of these field-collected data demonstrated a range expansion into northern and western NY during the last decade. Nymphal abundances increased in newly colonized areas, while remaining stable in areas with long-standing populations over the last decade. These trends in the geographic range and abundance of nymphs correspond to both the geographic expansion ...

(Virginia Tech) Renowned tick immunobiologist Utpal Pal wants to adapt the rabies vaccination platform to produce antibodies that can protect against Borrelia burgdorferi, the bacteria responsible for Lyme disease. The intention is to apply this work to other tick-borne diseases in the future.

We report a case of acute neuroborreliosis that manifested as extended isolated cervical myelitis. Not only the manifestation as isolated myelitis in the early stages of borreliosis represents a rarity, but also the strong contrast between mild clinical symptoms and pronounced imaging findings in this case is remarkable.Case Rep Neurol 2020;12:276 –281

When we get an acute illness like the flu or a cold, we feel sick for a week or two and then get back to our usual lives. This is how illness is “supposed” to go. But what happens when illness doesn’t fit this bill? What do patients with chronic conditions like diabetes or multiple sclerosis, or with persistent symptoms of Lyme disease or long-haul COVID-19, do when they can’t go back to their normal lives? Having suffered from the latter two — tick-borne illnesses that have plagued me for two decades, and a case of COVID-19 that took four months to shake — I’ve learned a few lesso...

Abstract Companion animals can become infected with tick-borne diseases (TBDs) and can become hosts of transmission to humans, thereby damaging human health. To clarify whether companion animals are infested by ticks harboring TBD pathogens in humans, we detected TBD pathogens in ticks collected from dogs and cats brought to animal hospitals in Yamagata Prefecture, Japan. Investigation of 164 adult ticks collected from 88 dogs and 41 cats during March-July 2018 revealed the predominant tick species as Ixodes ovatus (n = 95, 57.9%), followed by Ixodes nipponensis (37, 22.6%) and Haemaphysalis flava (10, 6.1%). The ...

Ticks and mosquitoes don’t care about COVID-19 safety protocols. They don’t care that people are trying to squeeze out the last moments of this restrictive summer by getting outdoors, hiking, or just sitting on their decks at night and feeling something that’s close to normal. COVID-19 has commanded our attention and caused people to adapt their behaviors to prevent one major health concern, but it doesn’t mean others have been eliminated. “Masks and social distancing will do nothing to protect you from what ticks and mosquitoes potentially carry,” says Dr. Todd Ellerin, director of infe...
