The meningopolyneuritis first described in 1922 by Garin and Bujadoux develops after a tick bite. At the site of the bite in some of the cases, erythema chronicum migrans develops first. Severe pains follow in this area which may spread to other parts of the body. Then peripheral paralysis appears with asymmetrical distribution. The motor cerebral nerves, especially the facial nerve, are also f...

To the Editor: Rickettsia slovaca is a bacterium that infects Dermacentor marginatus ticks in central and western Europe. First detected in ticks, the bacterium was subsequently identified with genomic amplification by using polymerase chain reaction (PCR) followed by sequencing in a skin biopsy from a French patient (1). We describe the first isolation of the organism from a patient. A 79-year...

During the 3-year period (2020–2022), 49 cases of tick bites were presented to Japanese Red Cross Ashikaga Hospital in Tochigi Prefecture, Japan. More than 60% all between March and September occurred within two months (May June). Amblyomma testudinarium was responsible for 40 among bite cases. Specifically, 41 individuals this species (39 nymphs/2 adult females) linked (The point estimate 0.79...

A 63-year-old woman presented with fever, confusion, dysarthria (slurred speech), new-onset thrombocytopenia (26 3 10 /L platelets) and mild transaminitis 2 weeks after a tick bite to the left thigh. Physical examination was negative for splenomegaly, rash, or any other focal deficits. A review of the peripheral smear confirmed morulae inside the neutrophils suggestive of a diagnosis of human g...

The duration of tick attachment is one factor associated with risk for human infection caused by several tick-borne pathogens. We measured tick engorgement indices at known time intervals after tick attachment and used these indices to determine the length of time that ticks were attached to tick-bite victims in selected Rhode Island and Pennsylvania communities where the agents of Lyme disease...

The relapsing fever spirochete, Borrelia hermsii, alternates infections between a mammal and a tick vector. Whether the spirochete changes phenotypically in the different hosts was examined by allowing the tick vector Ornithodoros hermsi to feed on mice infected with serotype 7 or serotype 8 of B. hermsii. Upon infection of ticks, the spirochetal serotype-specific variable major proteins (Vmps)...

Ticks are capable of transmitting numerous pathogens to both humans and their pets. The risks of tick-borne disease risks vary geographically and are determined by the climate, environment, the presence of rodents and other mammal reservoirs, and the species of ticks parasitizing wild and domestic animals. Zoonoses such as Lyme borreliosis, tularemia, and tick-borne rickettsioses can emerge in ...

New human cases of tick-borne encephalitis (TBE) have recently been recorded outside the recognised foci of this disease, i.e. in the province of Trento in northern Italy. In order to predict the highest risk areas for increased TBE virus activity, we have combined cross-sectional serological data, obtained from 459 domestic goats, with analysis of the autumnal cooling rate based on Moderate Re...

Ticks are obligate haematophagous arthropods present all over the world able to produce human diseases. Several factors have increased the abundance, circulation and distribution of the pathogens transmitted by ticks, contributing to the change in the vector-borne diseases epidemiology in the last years. This review collects the most important measures for the prevention and prophylaxis of tick...
