Background and purpose: Tick paralysis is a relatively rare and fatal disease caused by some species of blood-sucking ticks of Ixodidae family including Ixodes scapularis and Dermacentor andersoni. This disease is characterized by ascending acute flaccid paralysis but could be misdiagnosed with other neurological diseases especially, Guillain-Barré syndrome because of similar clinical pr...
Prevention of tick bites and transmission of tick-borne pathogens requires the use of molecules that target physiological processes crucial to both tick and pathogen survival. These molecules are best tested in standardized in vitro assays. Because hard ticks require several days to feed to repletion, the development of in vitro feeding assays for these species is challenging. A standard and ea...
Background and Aim: Ixodidae (hard ticks) are obligate blood-feeders of vertebrates with majorroles in transmission of pathogenic microorganisms including theileriosis, babesiosis and CCHF virus, as well as relapsing fever, to domestic animals and humans. This study was conducted to determine the distribution of ixodidae species, vectors of Crimean-Congo hemorrhagic fever (CCHF), in the border ...
Host specificity of Neotropical hard ticks (Acari: Ixodidae) was analyzed by using the number of hosts species for each tick species and the index of host specificity S(TD)*, which integrates phylogenetic and ecological information. The analyses were based on 4172 records of hard ticks collected from wild and domestic tetrapods. Most tick species included in this study were associated with thre...
the economic importance of tick infestation on camels are important as they are important meat and milk producer animals in the less vegetation area of iran and their health and production are greatly affected by the high tick infestation. in this investigation, tick infestations on camels (camelus dromedarius) were determined in qeshm island, iran. a total number of 912 adult ticks (472 males ...
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...
background: crimean-congo hemorrhagic fever (cchf) is a severe tick-born illness caused by the cchfv. ruminant animals are the main host to ticks, and ticks are a vector of cchf. therefore, this survey was carried out in 2013 on ticks of khouzistan province, in the southwest of iran, to specify tick species parasitizing live stocks and their seasonal population dynamics. materials and methods: ...
A scalp mass surgically excised from a 4-year-old Korean boy was identified as a tick through histological observations. In sections of the mass, characteristic features of a tick, including its gross contour, cuticular structures, well developed musculature and salivary glands, and the capitulum, were discovered. In particular, the capitulum is anteriorly protruded, which strongly suggests tha...
a survey was carried out to investigate the frequency of hard tick species (acari: ixodidae) on sheep in khorasan razvi province. a total of 812 ticks were collected from the sheep of different areas of khorsan razavi province five species were identified as follow: rhipicephalus turanicus (59.23%), hyalomma.marginatum turanicum (25.73%), hyalomma excavatum (14.8%), hyalomma anatolicum (8.3...
