It ’ s High Time for Ticks, Which Are Spreading Diseases Farther
The disease-carrying blood suckers are spreading more pathogens and putting more Americans at risk, even for more rare illnesses.
CONCLUSIONS: This study demonstrates the potential danger from the inadvertent introduction of novel disease pathogens and vectors. Awareness of co-infections and Dermacentor reticulatus-related pathogens needs to be increased. PMID: 31694625 [PubMed - in process]

Dr. Derek Monette: Today's case is that of a 46-year-old male with recent diagnoses of Lyme disease and babesiosis who presented to our emergency department (ED) with abdominal pain, nausea, and diarrhea. The patient was previously healthy and had been well until approximately 2 weeks before the day of ED presentation, when he developed headache, fatigue, and myalgias. He also noticed that his right calf “looks sunburned,” and was warm to the touch. He was evaluated by his primary care physician (PCP) after 1 week of symptoms.

This study demonstrates the effect of only simultaneous infection by B. burgdorferi and B. microti on each pathogen, immune response and on disease manifestations with respect to infection by the spirochete and the parasite. In our future studies, we will examine the overall effects of sequential infection by these pathogens on host immune responses and disease outcomes.

DearbornAbstractIxodes scapularis is responsible for the transmission of a variety of pathogens in North America, including Borrelia burgdorferi sensu stricto, Anaplasma phagocytophilum and Babesia microti. Songbirds have previously been described as agents of tick dispersal, and a combination of empirical data and modeling efforts have implicated songbirds in the range expansion of I. scapularis northward into Canada during spring bird migration. The role of fall bird migration has received comparat...
