| ticks (acari:ixodidae) of the blue and white nile ecosystems in the sudan with particular reference to the rhipicephalus sanguineus group. | twenty-four adult ixodid tick species, infesting livestock and some wildlife hosts along the blue and white nile in the sudan, were identified. three species, boophilus geigyi, rhipicephalus camicasi and r. bergeoni, were recorded for the first time from the sudan. tick numbers on indigenous breeds of cattle (bos indicus) were relatively low, ranging between 17.1 and 40.5 per animal. young cattle grazing with the herd carried significantly fewer ticks than older animals. with the exception of b. ... | 1987 | 3331134 |
| distinguishing species and populations of rhipicephaline ticks with its 2 ribosomal rna. | most populations and some species of ticks of the genera boophilus (5 spp.) and rhipicephalus (ca. 75 spp.) cannot be distinguished phenotypically. moreover, there is doubt about the validity of species in these genera. i studied the entire second internal transcribed spacer (its 2) rrna of 16 populations of rhipicephaline ticks to address these problems: boophilus microplus from australia, kenya, south africa and brazil (4 populations); boophilus decoloratus from kenya; rhipicephalus appendicul ... | 1998 | 9794625 |
| distribution and population dynamics of ticks (acari: ixodidae) infesting sheep in sennar state, sudan. | a cross-sectional survey of ticks infesting sheep was conducted in sennar state, sudan. a total body collection of ticks was carried out at five localities sennar town, singa, dinder, abu naama and um banein on two types of desert sheep (watish and ashgar) on two farms at each locality at two monthly intervals for one year starting july 2002 to may 2003. four tick genera and eight species were identified. they were amblyomma lepidum, hyalomma anatolicum anatolicum, hyalomma truncatum, rhipicepha ... | 2007 | 18453239 |
| tick-borne infections in human and animal population worldwide. | the abundance and activity of ectoparasites and its hosts are affected by various abiotic factors, such as climate and other organisms (predators, pathogens and competitors) presenting thus multiples forms of association (obligate to facultative, permanent to intermittent and superficial to subcutaneous) developed during long co-evolving processes. ticks are ectoparasites widespread globally and its eco epidemiology are closely related to the environmental conditions. they are obligatory hematop ... | 2015 | 27047089 |
| morphological and genetic diversity of rhipicephalus sanguineus sensu lato from the new and old worlds. | the taxonomic status of the brown dog tick (rhipicephalus sanguineus sensu stricto), which has long been regarded as the most widespread tick worldwide and a vector of many pathogens to dogs and humans, is currently under dispute. | 2013 | 23880226 |
| a secondary structural common core in the ribosomal its2 (internal transcribed spacer) of culexspecies from diverse geographical locations. | in the present study, sequence and structural analysis of its2 region (the spacer segment between 5.8s and 28s rrna of mature rrna sequences) of 7 culex species belonging to 5 different geographical locations was carried out. alignment of the its2 sequence from the 7 species revealed 8 homologous domains. four species namely c. vishnui, c. annulus, c. pipiens, c. quiquefasciatusshowed high sequence (98-100%) and rna secondary structure similarity. the its2 similarity among different species is h ... | 2005 | 17597853 |
| molecular detection of anaplasma platys infection in free-roaming dogs and ticks from kenya and ivory coast. | anaplasma platys is a bacterium parasitic in the canine platelets, representing the causative agent of canine cyclic thrombocytopenia, with a worldwide distribution, mainly in tropical countries. the agent has zoonotic potential, being reported in several human clinical cases. the suspected vector is the tick rhipicephalus sanguineus (sensu lato), widely distributed in animals and humans in the tropical regions of south america, africa, asia and australia, but also in southern europe. only few s ... | 2016 | 26984538 |
| genetic analysis of rhipicephalus sanguineus sensu lato ticks parasites of dogs in africa north of the sahara based on mitochondrial dna sequences. | the aim of this work was to determine the evolutionary relationship among tick populations of rhipicephalus sanguineus sensu lato distributed in africa north of the sahara and different lineages of r. sanguineus s.l. distributed in different regions of sub-saharan africa, america and europe through the analysis of dna sequences of two mitochondrial genes. one hundred and thirty six 16s rrna gene sequences and twenty-seven 12s rrna gene sequences of r. sanguineus s.l. were analyzed. phylogenetic ... | 2017 | 28495189 |
| new molecular data shed light on the global phylogeny and species limits of the rhipicephalus sanguineus complex. | the rhipicephalus sanguineus complex is a group of closely related tick species distributed all around the world. in this study, using mitochondrial 16s ribosomal dna, new specimens of r sanguineus sensu lato from turkey and rhipicephalus camicasi from kenya, were evaluated together with available sequences of this complex in genbank. our objectives were to delimit the complex, re-evaluate its global phylogeny and develop a reconstruction of its biogeographic history. given turkey's geographical ... | 2016 | 27050755 |
