background: a molecular survey was conducted to investigatethe presence of pathogenic borrelia persica species caus­ing the tick borne relapsing fever (tbrf) in takistan district qazvin province, western iran. methods: a number of 1021 s oft ticks were collected from 31 villages including previously reported infected and none-infected tbrf cases and individually examined for the presenceof b. p...

We report a case of infestation long-term laboratory colony soft ticks, Ornithodoros moubata, with mites that were molecularly identified as Tyrophagus fanetzhangorum using the COI gene and discuss possible nature interaction between these two acarines.

Adults of 3 tick species (Acari: Argasidae) identified as Antricola guglielmonei, Antricola delacruzi, and Carios rondoniensis n. sp. were collected on bat guano in a cave in the state of Rondônia, western Amazon, Brazil. Adults of C. rondoniensis possess a unique combination of characters that distinguish them from all described adults in the Argasidae, i.e., a large spiracular plate densely f...

Tick-borne relapsing fever (TBRF), is caused by several species of Borrelia spirochetes, which are transmitted to humans through the bites of Ornithodoros spp. soft ticks. Wild rodents and insectivores are common reservoir hosts. TBRF is responsible for recurring fever associated with spirochetemia. The epidemiology of TBRF has not been well documented in South America where three endemic ticks...

Tick-borne relapsing fever (TBRF) is caused by Borrelia species transmitted to humans by infected Ornithodoros sp. ticks. The disease has been rarely described in North Africa, and in Tunisia the local transmission of TBRF seems to have disappeared or is undiagnosed. A longitudinal study was conducted in 14 sites located in four different bioclimatic zones of Tunisia to assess both the distribu...

BACKGROUND Tick-borne relapsing fever spirochetes are maintained in endemic foci that involve a diversity of small mammals and argasid ticks in the genus Ornithodoros. Most epidemiological studies of tick-borne relapsing fever in West Africa caused by Borrelia crocidurae have been conducted in Senegal. The risk for humans to acquire relapsing fever in Mali is uncertain, as only a few human case...

Geigy & Wagner (1957) and Wagner-Jevseenko (1958) studied normal mitoses in squash preparations of metaphase nuclei in the argasid tick Ornithodoros moubata during the transition of the oogonia to the primary oocytes and anived at the diploid chromosome number 20. Morphologically the chromosomes could be differentiated into two main groups: three large, rod-shaped chromosomes, ca. 1· 7 p. long,...

background: besides of transmitting several diseases to animals, and tick paralysis, ornithodoros lahorensis induce skin lesions. this experiment was done to determine histopathological features of adult o. lahorensis bite on rat. methods: in this investigation adult male rats were infested with o. lahorensis ticks. animals were divided into two groups and euthanized two days and two weeks afte...
