Chloride Balance in Feeding of Ixodid and Argasid Ticks (Acarina: Ixodoidea)

Variation in genome size of argasid and ixodid ticks.

The suborder Ixodida includes many tick species of medical and veterinary importance, but little is known about the genomic characteristics of these ticks. We report the first study to determine genome size in two species of Argasidae (soft ticks) and seven species of Ixodidae (hard ticks) using flow cytometry analysis of fluorescent stained nuclei. Our results indicate a large haploid genome s...

Ixodid and Argasid Tick Species and West Nile Virus

Control of West Nile virus (WNV) can only be effective if the vectors and reservoirs of the virus are identified and controlled. Although mosquitoes are the primary vectors, WNV has repeatedly been isolated from ticks. Therefore, tick-borne transmission studies were performed with an ixodid (Ixodes ricinus) and an argasid tick species (Ornithodoros moubata). Both species became infected after f...

Rickettsiae in Ixodid Ticks, Sicily

Emerging Infectious Diseases • www.cdc.gov/eid • Vol. 11, No. 3, March 2005 509 dling guidelines. A facility inspection and review of the caterer’s procedures identified improper holding temperatures for potentially hazardous foods as the likely cause of the outbreak. In this incident, prompt action by the police department, which employed an agency-wide radio communications system to warn offi...

The Ixodes ticks of Chiroptera (Ixodoidea, Ixodidae).

Rickettsiae and Borrelia burgdorferi in ixodid ticks.

Nymphs and adults of hard-bodied ticks were collected in Connecticut and tested by direct and indirect immunofluorescence staining methods for rickettsiae and Borrelia burgdorferi. Of the 609 Ixodes dammini ticks examined, 59 (9.7%) harbored rickettsialike microorganisms in hemocytes (blood cells). These bacteria reacted with fluorescein-conjugated antiserum to Ehrlichia canis, the etiologic ag...
