Birds transport ticks into Canada during northward spring migration, and some of these are infected with tick-borne zoonotic pathogens. Some Amblyomma species harbour pathogens that cause debilitating diseases can be fatal to humans, domestic wildlife animals. At least 65 spp. indigenous in the Western Hemisphere, approximately half bite humans. longirostre carries Rickettsia amblyommatis which...

Emerging Infectious Diseases • www.cdc.gov/eid • Vol. 19, No. 7, July 2013 1173 positive by ELISA (Enzygnost AntiTBE/FSME Virus [IgG, IgM] Siemens, Erlangen, Germany) or PCR (online Technical Appendix). Since the 1980s, Sweden has experienced a 4-fold increase in human TBE incidence, with spread southwest (10). The emergence of the TBEV strain T2 closely related to isolates from Sweden may be a...

Ticks transmit a variety of infectious diseases. Diagnosis requires verification of a tick's presence. Here, we describe a 61-year-old woman bitten by an eight-legged nymphal Amblyomma testudinarium. We re-emphasize the usefulness of dermoscopy for identifying signs of the bite and determining the species of the biting tick.

Lyme disease (LD) is the most commonly diagnosed vector-borne illness in the U.S. Analysis of ticks that are removed from patients (rather than collected from the environment) may inform LD surveillance. In this ecological study, LD rates among active component U.S. Armed Forces in the eastern U.S. were compared with tick data from the U.S. Army Public Health Command Human Tick Test Kit Program...

The phylum Arthropoda includes arachnids and insects. Although their bites typically cause only local reactions, some species are venomous or transmit disease. The two medically important spiders in the United States are widow spiders (Latrodectus), the bite of which causes intense muscle spasms, and the brown recluse (Loxosceles), which may cause skin necrosis. Widow bites usually respond to n...

Since the description of tick-typhus by Major-General (then Major) J. W. D. Megaw, in 1917, cases have been reported from various parts of India mostly contracted in jungles, but seldom in a town. Moreover in very few cases could a previous tick bite be established, although the tick is supposed to be the infecting agent. The following cases are of interest as they both occurred in a big town (...
