BACKGROUND Relapsing fever caused by Borrelia persica, is an acute tick-borne disease which is transmitted by soft ticks of Ornithodoros tholozani to human. METHODS Value of PCR and xenodiagnosis for detection of B. persica in O. tholozani ticks was compared. Sixty-four Borrelia-free ticks were fed on infected guinea pigs and used for the experiments. For xenodiagnosis, a group of 32 ticks in...

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...

In order to describe the developmental biology of the tick Argas neghmei Kohls & Hoogstraal under laboratory conditions, 40 females and 40 males were collected from chicken coops located in Calama (II Region, Chile). They were fed on chickens and maintained under two laboratory conditions: one group at 30 +/- 5 degrees C and 35 +/- 5 % RH and another at 27 +/- 5 degrees C and 80 +/- 5 % RH, bot...

AIM The aim of this study was to determine the epidemiological infestation and identification of Ixodidae and Argasidae ticks species in buffalo of different parts of district Khairpur, Pakistan. MATERIALS AND METHODS A total of 720 Water buffaloes from three tehsils (subdivisions) were selected randomly and examined from organized and unorganized dairy farms for tick infestation in district ...

The generally large acarines included in the superfamily Ixodoidea apparently evolved as obligate parasites of Reptilia in the late Paleozoic or early Mezozoic era. During subsequent coevolution with birds and mammals, adaptations of most tick species have been conservative. Structural, developmental, physiological, ethological, and reproductive properties and processes have changed, but chiefl...
