A survey was carried out to investigate the occurrence of hard tick species (Acari: Ixodidae) infesting domestic dogs in Hungary. Forty veterinary clinics from a wide geographical area were asked to collect hard ticks from dogs and to complete a questionnaire. In total, 25 veterinary clinics submitted 900 ticks from 310 dogs. Intensity of infestation ranged from one to 78 per dog. The most pref...

In a previous research project [5], we found there are several disadvantages of the current Linux scheduler. So we employed a alternative scheduler, Resource-Based Earliest Deadline First scheduler(RB-EDF), to solve these problems. Though RB-EDF performs better than the Linux scheduler in handling soft realtime processes, it can not enforce resource usages smaller than 1 tick(10ms) using the re...

A survey was carried out to investigate the prevalence of hard tick species (Acari: Ixodidae) on cattle in Mazandaran province, Iran. A total of 953 ticks were collected from 86 infested cattle during activating seasons of ticks during 2004-2005. Nine species were identified: Boophilus annulatus (51.3%), Rhipicephalus bursa (16.8%), Haemaphysalis punctata (6.3%), Ixodes ricinus (6.8%), Hyalomma...

Ticks transmit mere different kinds ef pathogenic organisms than any other hematophagous arthropod. This paper attcmpts to review the literature available on the cell-mediated and humoTa] responses ofticks. The eell-mediated defense responses by invertebrates are impler than vertebrates, but are elTectivc as a second line ofdefense against invasion by microorganisms. Hemocytes play a major role...

The present concept of the transmission of Lyme disease from Borrelia-infected Ixodes sp. ticks to the naïve host assumes that a low number of spirochetes that manage to penetrate the midgut epithelium migrate through the hemocoel to the salivary glands and subsequently infect the host with the aid of immunomodulatory compounds present in tick saliva. Therefore, humoral and/or cellular immune r...

Tick-transmitted zoonoses such as human granulocytic anaplasmosis (HGA), Lyme borreliosis and tick-borne encephalitis (TBE) are endemic in several European countries, including Slovenia. Ixodes ricinus, the most prevalent species of hard ticks in Slovenia, is the principal vector for Borrelia burgdorferi sensu lato, Anaplasma phagocytophilum and TBE virus [1]. Information on clinically manifest...

1. Although behaviours can contribute to the heterogeneity in parasite load among hosts, links between consistent individual differences in behaviour and parasitic infection have received little attention. We investigated the role of host activity and exploration on hard tick infestations of marked individuals in a population of Siberian chipmunks Tamias sibiricus introduced in a suburban Frenc...

The excellent Comment by Ulrike Munderloh and Timothy Kurtti (Sept 17, p 962)1 describes the complex life cycle of Borrelia burgdorferi, the spirochaetal agent of Lyme disease, as it traffics between tick and mammalian hosts. The Comment highlights a growing problem with Lyme disease: while what is known about the basic science of this tick-borne illness becomes more complex, the clinical scien...

A cDNA expression library from the salivary glands of hard tick, Haemaphysalis longicornis, was constructed. Immunoscreening was performed using sera of the rabbit repeatedly infested with ticks and seventeen positive clones were obtained. A BLASTP search suggested that 8 sequences matched with that of hypothetical H. longicornis sequence and one clone encoded HL35 antigen U from the same tick ...
