Aim . To improve emergency diagnostic measures and preventive antimicrobial therapy in patients with ixodid tick bites using molecular genetic techniques for identification of Вorrelia spp. Materials Methods Borrelia strains were isolated by inoculation suspension on the BSK-H medium. Molecular screening was performed real-time polymerase chain reaction (PCR) sequencing. In total, we examined 4...

b a ckground: babesiosis is a haemoparasitic disease of domestic and wild animals caused by species of the genus bab esia . bab esia bigemina , b . bovis and b . divergens are known to be pathogenic in cattle. the disease is transmit- ted during blood feeding by infected ticks and is the most economically important tick-borne disease in tropical and subtropical areas. ixodid ticks are vectors i...

Despite the large number of collection records, there are no recent collections of ixodid ticks of this magnitude in the Waterberg area, Limpopo Province, South Africa. Free-living ticks on a commercial game farm were obtained by a total of 432 drag-samples in eight sample sites from September 2003 to August 2008. The ticks were collected to establish the difference between tick species and den...

A total of 264 scrub hares (Lepus saxatilis) were examined for ixodid ticks at various localities in the Kruger National Park, eastern Transvaal Lowveld. Thirteen tick species were recovered from these hares. The seasonal abundances of the immature stages of Amblyomma hebraeum, Amblyomma marmoreum, Hyalomma truncatum, Rhipicephalus appendiculatus, Rhipicephalus evertsi evertsi, Rhipicephalus si...

1. Salivary glands of the female ixodid tick, Dermacentor andersoni, secrete fluid in vitro when bathed in a slightly modified version of the mammalian tissue culture medium 'TC 199'. 2. Rate of salivation in vitro increases with progression of feeding, but there is no comparable increase in dry weight of the salivary glands during the early phase of engorgement. Engorged ticks secreted at only...

This study evaluated the influence of the initial weight, feeding period and temperature on weight gain and biological parameters of the non-parasitic phase of partially engorged Rhipicephalus sanguineus females that were artificially fed using plastic tips as feeding devices. The device did not alter the oviposition of the females or any other parameters evaluated. Furthermore, it was observed...

The objective of this study was to determine the species and distribution of ticks infesting domestic dogs in southern Mozambique. To this end 89 collections were taken from dogs and the geographic coordinates of the localities at which they were made noted. Fifty-eight of these collections were from animals in the city of Maputo and 16 from animals at rural settlements close to Maputo. A furth...

Nymphs and adults of hard-bodied ticks were collected in Connecticut and tested by direct and indirect immunofluorescence staining methods for rickettsiae and Borrelia burgdorferi. Of the 609 Ixodes dammini ticks examined, 59 (9.7%) harbored rickettsialike microorganisms in hemocytes (blood cells). These bacteria reacted with fluorescein-conjugated antiserum to Ehrlichia canis, the etiologic ag...

The prevalence of ectoparasites on a total of 36 impala (Aepyceros melampus) slaughtered monthly from February 1975 to February 1976 and a total of 24 cattle slaughtered monthly from March 1976 to March 1977 in the Nylsvley Provincial Nature Reserve was determined. Six species of ixodid ticks were collected from the impala and these, in order of abundance, were: Rhipicephalus evertsi evertsi, R...

The objective of this study was to determine the species spectrum of ixodid ticks infesting birds in Free State Province, South Africa. To this end a large number of birds belonging to several species were examined for ticks and a total of 180 birds belonging to 39 species at 17 localities were infested, and ticks belonging to eight species were recovered. The immature stages of only two, namel...
