overall 1906 adult ticks, as well as their nymphs and larvae were collected from the body surface of cattle in the animal husbandries located in north, north-east, south and south-west of ahwaz area, khoozestan, iran, during 1991-1993. the identified adult ticks were hyalomma anatolicum anatolicum (c.l.koch, 1844), hyalomma anatolicum excavatum (c.l. koch, 1844), boophilus annulatus (say, 1821)...

The present communication describes the detailed day wise study of histological changes of the ovary of Rhipicephalus (Boophilus) annulatus in the postengorgement period together with the systematic classification of their oocytes. The ovary of R. (B.) annulatus is panoistic type with an asynchronous development of oocytes. All the stages (II, III, IV, and V) of oocytes except stage I were simi...

Ticks are obligate haematophagous ectoparasites of wild and domestic animals as well as humans, considered to be second worldwide to mosquitoes as vectors of human diseases, but the most important vectors of disease-causing pathogens in domestic and wild animals. Babesia spp. are tick-borne pathogens that cause a disease called babesiosis in a wide range of animals and in humans. In particular,...

Before the eradication of Boophilus ticks from the United States, Rhipicephalus (Boophilus) microplus (Canestrini) and Rhipicephalus (Boophilus) annulatus (Say) were important biological vectors of the cattle pathogen Anaplasma marginale Theiler. In the absence of Boophilus ticks, A. marginale continues to be transmitted by Dermacentor ticks. However, a few U.S. strains are not transmissible by...

BACKGROUND The aim of this study was to investigate the 'acaricidal effect' of Zataria multiflora and Artemisia annua essential oils on Rhipicephalus (Boophilus) annulatus. METHODS This study was carried out in 2009 in the Laboratory of Parasitology of the Faculty of Veterinary Medicine of Shahrekord University, west central Iran. Six dilutions (5, 10, 20, 40, 60 and 80 µL/cm(3)) of both esse...

In the absence of a satisfactory definition of Rickettsia the observations herein recorded were arbitrarily limited to bacterium-like organisms which are intracellular and Gram-negative. Rickettsia of this type were found in the following species: Amblyomma americana, Amblyomma hebraeum, Boophilus decoloratus, Atomus sp., Casinaria infesta, Chrysopa oculata, Ctenocephalus canis, Dermacentor var...

Review This is a unique book dealing with tick species imported to the US through human immigration, migratory birds, exotic animal trade etc. Although the name might suggest it would focus exclusively with ticks found in the US, there are also a few chapters explaining from which continents these invasive ticks were coming and which give valuable information about their ecology, related epidem...
