Borrelia hispanica is the etiological pathogen of tick-borne relapsing fever, transmitted to humans by infected Ornithodoros erraticus ticks. Here we present the 1,783,846-bp draft genome sequence, with an average G+C content of 28%. It has 2,140 open reading frames, 3 ribosomal RNAs, and 32 transfer RNAs.

The hematophagous soft tick Ornithodoros erraticus feeds nocturnally on multiple warm-blooded vertebrate hosts. This tick is often found living buried in the soil of traditional pigpens. O. erraticus is an important infectious disease vector both for humans and animals. In the Iberian Peninsula, this tick serves as the vector of human tick-borne relapsing fever caused by the spirochete Borrelia...

24 25 The argasid ticks O. erraticus and O. moubata are of great medical and veterinary 26 importance because they are vectors of the African swine fever virus and several species of 27 human relapsing fever borreliae. Biocontrol of these ticks using entomopathogenic fungi has not 28 been previously reported. We examined the pathogenicity to different developmental stages of 29 these two argasi...

background: west azerbaijan is considered as a main region for domestic animal breeding. due to importance of herd as a main host and ticks as a vector of relapsing fever and cchf, a comprehensive study was undertaken in the region. methods: outdoor, indoor collection as well as ticks stick to the animals' body were collected and identified. the study was conducted during the whole seasons in 2...

A woman with relapsing polychondritis presented with progressive and deforming polyarthritis (but always negative for rheumatoid factor) 14 years before the appearance of typical clinical and histological changes of nasal and auricular cartilage destruction.

Many argasid tick species are known only through their larval descriptions, in which the chaetotaxy, together with other external morphological characteristics, has been used to separate genera and species. However, the illustrations of these features are based on optical microscopy alone and many of these features are not clearly defined. Because of the difficulties in determining the larval a...

tick-borne diseases like tick-borne relapsing fever are a public health problem in iran. its occurrence is more prevalent in north part of country. in order to determine the distribution of soft ticks, argasidae, and their infection with borrelia species in hamadan province, 53 villages were selected randomly. a total of 4805 ticks were collected directly from human dwellings, poultries, and an...

background: the distribution and ecological preferences of ticks of domestic animals in north of iran were studied four times a year from 2002 to 2005. methods: a total of 1720 tick specimens were collected from cattle, sheep and goats from different localities of caspian sea areas consisting of guilan, mazandaran, golestan and ardebil provinces, iran. results: fourteen tick species were identi...
