We describe a rare clinical finding of conjunctival tick attachment in a child. A 10-year-old boy presented to the clinic with right-eye itch. He was found to have a live tick firmly attached to his right temporal conjunctiva. The tick was identified as the larval stage of the paralysis tick, Ixodes holocyclus. The tick was removed completely by conjunctival excision. Although various methods o...

[The] understanding which is relevant to the sciences of man is something more than this implicit grasp on things. It is related rather to the kind of understanding we invoke in personal relations when we say, for instance: ‘I find him hard to understand’; or at last I understand her’. To switch for a minute to another language, it is the kind of understanding one invokes in French when one say...

QUESTION UNDER STUDY To determine the incidence and determinants of tick related diseases in Switzerland, for example tick bites and Lyme borreliosis in primary care and tick borne encephalitis. METHODS Analysis of the Swiss data collected by mandatory and facultative surveillance systems for the reporting period of 2008 to 2011. RESULTS Tick related diseases in Switzerland are common. Abou...

background tick paralysis is a disease of human and animals characterized by an acute ascending flaccid motor paralysis. the condition may terminate fatally unless the tick(s) are removed before respiratory paralysis occurs. patient a 48 years old female was referred to a clinic in tehran with edema at the head and neck regions. she had fever and disequilibrium. she reported a travel to mountai...

Tick-borne diseases are on the rise. Lyme borreliosis is prevalent throughout the Northern Hemisphere, and the same Ixodes tick species transmitting the etiologic agents of this disease also serve as vectors of pathogens causing human babesiosis, human granulocytic anaplasmosis, and tick-borne encephalitis. Recently, several novel agents of rickettsial diseases have been described. Despite an e...

The origins of tick toxicoses remain a subject of controversy because no molecular data are yet available to study the evolution of tick-derived toxins. In this study we describe the molecular structure of toxins from the soft tick, Ornithodoros savignyi. The tick salivary gland proteins (TSGPs) are four highly abundant proteins proposed to play a role in salivary gland granule biogenesis of th...
