Molecular Detection of Tick-Borne Pathogens Associated With Ixodid Tick Species Infesting Migratory Songbirds and Ruminants
<p>Ticks are hematophagous arthropods and capable of inoculating various infectious agents to their vertebrate hosts. Ticks attached to birds and ruminants are capable of carrying tick-transmitted microorganisms. In our study, the prevalence of tick-borne pathogens was examined in ticks infesting …

Vitellogenesis in <i>Hyalomma dromedarii</i> (Acari: Ixodidae): A Model for Analysis of Endocrine Regulation in Ixodid Ticks
… vitellogenins, were characterized in the ixodid tick <em>Hyalomma dromedarii.</em> Three vitellins were identified. The high molecular weight vitellins, VN A and VN B, were composed of seven homologous molecular weight subunit polypeptides, VN 1-7. VN A appears to be a dimeric form of VN …

A Hitchhiker’s Guide to Invasion Biology: Describing the Ecological Mechanisms Underlying the Range Expansions of Two Ixodid Tick Species
… of time between bloodmeals. Two species of ixodid tick, Ixodes affinis and Amblyomma maculatum, are simultaneously expanding their ranges throughout the Mid-Atlantic region of the United States, and provide a case study from which to examine the relative importance of host choice and …

Evidence for the Sensory Receptor(s) of the Mounting Sex Pheromone in Two Species of Ixodid Ticks, <i>Dermacentor variabilis</i> (Say) and <i>Dermacentor andersoni</i> Stiles
… for an understanding of mating behavior in ixodid ticks is discussed.</p>

Interference with biologic transmission of Anaplasma marginale by targeting the tick-pathogen interface
… globally renowned vectors for numerous zoonoses. Ixodid ticks transmit a variety of viral, bacterial, and protozoan pathogens to their vertebrate hosts. Because of the expansion of the geographic ranges of both ticks and pathogens, increasing tick populations, emerging tick-borne pathogens and …

Theileria orientalis Ikeda Genotype: Implications for Cattle Health in Virginia
… genotypes. These organisms are carried by the ixodid tick, Haemaphysalis longicornis, recently identified in the United States. Our work has been focused on initially identifying the protozoal organisms, crafting assays to aid in the identification of these organisms in clinically affected …

Molecular characterization and in vitro functional analysis of putative immunoprotective molecules in the soft tick, Ornithodoros savignyi
… in the induction stimuli between argasid and ixodid ticks. Lysozyme catalyzes the cleavage of the β-1,4 glycosidic bond between N-acetyl muramic acid and N-acetyl glucosamine of the peptidoglycan layer of bacterial cell walls affording the molecule antibacterial activity. In argasid ticks, …

A deeper look into the morphology and receptors found in the tick (Acari: Ixodidae) chemoperception structure, the Haller's organ
… Haller's organ is a sensory structure unique to ixodid ticks that assists in host seeking behaviors. Presented here are the results of a detailed comparative study of the morphology and the chemoperception gene expression of the Haller’s organ. The morphometrics study focuses on the three …

Modeling host responses to tick feeding and tick-borne flavivirus evolution and dispersal
Ixodid ticks are hematophagous arthropods that feed on host animals for an extended period of time. To facilitate feeding, ticks secrete a complex mixture of salivary molecules that inhibit host responses such as coagulation, complement, itch responses, and immune responses. Ticks act as vectors …

Exploring the Neuropeptides, Neuropeptide Receptors and Neurotransmitter Receptors in the Synganglia of Part-Fed Females of <i>Ornithodoros turicata</i> (Argasidae) and <i>Ixodes scapularis</i> (Ixodidae) with Insights Into Their Roles in Contrasting Biology
<p>The neurobiology of the synganglion (central nervous system) of the Lyme disease tick, <em>Ixodes scapularis</em> and the soft tick <em>Ornithodoros turicata</em> was evaluated using Illumina GAII high throughput sequencing which generated high coverage cDNA libraries (transcriptomes). These …
