Five tick-borne pathogens were recently identified in New York and Connecticut using a multiplex real-time reverse transcription-PCR assay. The assay was able to simultaneously detect and differentiate Anaplasma phagocytophilum, Borrelia burgdorferi, Borrelia miyamotoi, Babesia microti, and the Powassan virus in I. scapularis (black-legged) ticks.
Did you know the cat you may be cuddling with on your couch every evening could be infected with a host of tick-borne diseases? Unlike our canine friends, cats are typically not symptomatic when it comes to such diseases. But as researchers have found, that doesn’t mean they are free from disease.
Lyme disease patients oftentimes suffer from ongoing illness following treatment. A study by Bechtold and colleagues found that 31% of patients remained in significant pain for months after a three-week course of doxycycline to treat an EM rash.  Six percent of their patients developed post-treatment Lyme disease syndrome (PTLDS). Now, a new case report examines the effectiveness of intravenous ketamine on managing pain in a patient with post-treatment Lyme disease syndrome.
There are many documented cases of patients with Lyme disease suffering from suicidal or homicidal tendencies. In the journal Neuropsychiatric Disease and Treatment, psychiatrist Robert Bransfield, MD, expresses his concern for this under-recognized patient population. “Suicidal and homicidal tendencies after Lyme disease are clearly an ignored problem that deserves greater attention.” 
Borrelia burgdorferi sensu lato (Bb s.l.), the causative agent of Lyme disease, was first reported in 2013 in Ixodes aragaoi ticks in Uruguayan Pampa and has since been found in Argentina and Chile. Now, a new study reports the results of a state surveillance program investigating the presence of Bb in Ixodes spp ticks in Brazilian Pampa.
In a 2017 issue of the American Journal of Medicine , Dr. Rosalie Greenberg from Overlook Hospital in Summit, New Jersey, responds to an article published by Drs. Shapiro, Baker and Wormser entitled “False and Misleading Information about Lyme Disease.” 
Twelve out of 28 children with Lyme disease evaluated at an academic medical center in the Netherlands remained ill with post-treatment Lyme borreliosis syndrome (PTLBS). These 12 children presented with various complaints, including fatigue, general malaise and pain. There were no other medical explanations for their complaints and all were positive for Borrelia burgdorferi sl based on two-tier testing of C6-Lyme enzyme immunoassay (EIA) and IgG/IgM immunoblots. 
Babesia, a severe, potentially life threatening illness, has been identified in as many as 40% of individuals with Lyme disease in the North Eastern USA. The clinical spectrum now includes what has been described as “asymptomatic.” This is particularly concerning given that the infection can be acquired not only through a tick bite but through blood transfusions.
In his review of autonomic dysfunction due to infectious diseases, Artal from the Neurology Department at Raigmore Hospital in the UK, writes, “Complex regional pain syndromes [CRPS] and reflex sympathetic dystrophy with regional sympathetic hyperactivity have also been reported in some patients with Lyme disease.”  CRPS is characterized by considerable pain (allodynia, hyperalgesia), edema, trophic changes of the skin and muscles and sudomotor disorders.
Numerous studies have found that wearing permethrin-treated clothing can reduce the risk of tick bites. A University of Rhode Island study found that people wearing permethrin-treated sneakers and socks were 73.6 times less likely to have a tick bite than those wearing untreated footwear.  But very few studies have looked at the behavior of a tick when it comes in contact with permethrin-treated clothing. Does it climb onto the insecticide-soaked textile or avoid it entirely? Does permethrin actually kill ticks?
