rhipicephalus การใช้

• The organism is transmitted by various tick species including Rhipicephalus, Dermacentor and Haemaphysalis.
• The virus of Nairobi sheep disease in East Africa is transmitted by " Rhipicephalus " ticks.
• Wild hedgehogs have been found to carry Rhipicephalus sanguineus, the brown dog tick, which can transmit Boutonneuse fever.
• DNA was first reported in " Rhipicephalus sanguineus " and " Dermacentor nitens " ticks in Peru.
• Many " Rhipicephalus " are of economic, medical, and veterinary importance because they are tick-caused paralysis.
• The vector was identified in 1907 by Christopher to be the brown dog tick ( " Rhipicephalus sanguineus " ).
• The brown dog tick, " Rhipicephalus sanguineus ", acts as the nymph and adult stage in transstadial transmission.
• "Acorus calamus " may prove to be an effective control measure against cattle tick, Rhipicephalus ( Boophilus ) microplus.
• The rationale for such vaccination follows invention of a commercial synthetic antigen vaccine against the tropical cattle tick, " Rhipicephalus microplus ".
• Breeding for resistant cattle has been successful for their ability to acquire strong immune resistance to " Rhipicephalus microplus " following natural exposure to these ticks.
• An adult will take nearly 100 blood-engorged female " Rhipicephalus ( Boophilus ) decoloratus " ticks, or more than 12, 000 larvae in a day.
• Likely transmission vectors of BYS belong to the " Amblyomma " and " Rhipicephalus " genera, which could help to explain all the particularities observed in BYS versus LD.
• A similar disease in cattle, commonly known as tick fever, is spread by " Babesia bovis " and " B . bigemina " in the introduced cattle tick " Rhipicephalus microplus ".
• First recognized by Harry Hoogstraal as " Rhipicephalus longicoxatus " based on an incomplete published description, after discovery of the holotype of " R . longicoxatus ", it was described and named to honor Hoogstraal in 2009.
• The virus was isolated from pooled ticks ( " Amblyomma gemma " and " Rhipicephalus pulchellus " ) collected from cattle hides in Nairobi, Kenya, in October 1999 . The word'Kupe'is Kiswahili for tick.
• Arnold Theiler sent specimens of Blue tick ( " Boophilus decoloratus ", now known as " Rhipicephalus ( Boophilus ) decoloratus " ), known to be the usual vectors for Redwater, taken from infected cattle to Lounsbury in Cape Town.
• There, surprisingly, they caused no disease when introduced to healthy cattle, leading to the discovery that the disease was not Redwater, but a new protozoan parasite East Coast fever or " Theileria parva " transmitted by the tick " Rhipicephalus appendiculatus ".
• In areas endemic for heartwater there is likely to be use of dips against other ticks of domestic animals, such as " Rhipicephalus ( Boophilus ) " and " Hyalomma " species and this will usually contribute to control of vectors of " Ehrlichia ruminantium ".
• Lyme disease, or borreliosis, is caused by " Borrelia burgdorferi " and spread by " Ixodes pacificus " on the West coast of the United States and by " Rickettsia rickettsii ", which causes Rocky Mountain spotted fever, are both spread by the American dog tick, " Dermacentor variabilis ", and the brown dog tick, " Rhipicephalus sanguineous ".
