Ticks are amongst the important ectoparasites where livestock concerned, as they adversely affect animals through bloodsucking. In tropical and subtropical countries, transmit pathogens such babesiosis, theileriosis, ehrlichiosis, anaplasmosis in cattle, causing a reduction production rate significant concomitant economic losses. 80% of cattle population across world, with an estimated loss USD...
The mechanism of ixodid tick (Acari: Ixodidae) repellency by gum haggar, a resin produced by Commiphora holtziana (Burseraceae), was investigated by evaluating activity against the cattle tick, Boophilus microplus. In an arena bioassay, a hexane extract of the resin of C. holtziana exhibited a repellent effect lasting up to 5h. The hydrocarbon fraction of the resin extract was shown to account ...
Anaplasma spp. are significant arthropod-borne bacteria globally, but documented information about anaplasmosis in small ruminants the north of Iraq is insufficient. Hence, this study was conducted to determine prevalence and identify sheep goat tick vector populations Sulaymaniyah Governorate, Iraq. The population consisted 470 145 goats from 45 livestock farms 10 geographical locations Govern...
Ixodid ticks transmit several important viral pathogens. We isolated a new virus (Tofla virus: TFLV) from Heamaphysalis flava and Heamaphysalis formsensis in Japan. The full-genome sequences revealed that TFLV belonged to the genus Nairovirus, family Bunyaviridae. Phylogenetic analyses and neutralization tests suggested that TFLV is closely related to the Hazara virus and that it is classified ...
An anticoagulant isolated from salivary gland extracts of the ixodid tick Rhipicephalus appendiculatus was purified by gel filtration on Sephadex G-100, ion exchange on DEAE-cellulose, aprotinin-Sepharose, and by high-pressure-liquid size-exclusion chromatography. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis showed that the anticoagulant activity was associated with a protein of an...
Ticks are important vectors of disease and transmit an extensive array of bacterial, viral and protozoan diseases to both humans and dogs within a community. Borrelia burgdorferi, the causative agent of Lyme disease, has been extensively studied within both the human and veterinary population. Anaplasma phagocytophilum, an intracellular rickettsial pathogen also transmitted by ixodid ticks, has...
Larvae, nymphs, and adult stages of 3 species of ixodid ticks were collected by tick drag methods in Seoul during June-October 2013, and their infection status with severe fever with thrombocytopenia syndrome (SFTS) virus was examined using RT-PCR. During the period, 732 Haemaphysalis longicornis, 62 Haemaphysalis flava, and 2 Ixodes nipponensis specimens were collected. Among the specimens of ...
As evidence of global changes is accumulating, scientists are challenged to detect distribution changes of vectors, reservoirs and pathogens caused by anthropogenic and/or environmental changes. Statistical and mathematical distribution models are emerging for ixodid hard ticks whereas no prediction has ever been developed for argasid ones. These last organisms remain unknown and under-reported...
