UNLABELLED A wide range of bacterial pathogens have been identified in ticks, yet the diversity of viruses in ticks is largely unexplored. In the United States, Amblyomma americanum, Dermacentor variabilis, and Ixodes scapularis are among the principal tick species associated with pathogen transmission. We used high-throughput sequencing to characterize the viromes of these tick species and ide...

The purpose of this study was to provide molecular evidence of Rickettsia spp. in ticks collected from 2 sites of Cordoba. From May to June 2009, 1069 Amblyomma cajennense ticks were removed from 40 capybaras (Hydrochoerus hydrochaeris) in a rural locality of Monteria. Furthermore, 458 Amblyomma sp. larvae and 20 Amblyomma sp. nymphs were collected in a rural locality of Los Cordobas (Cordoba) ...

s of these presentations are included in this publication to inform other research groups of these activities, which were not yet at the stage where formal publication of results was possible. Participants divided into four groups after each field had been covered. They evaluated the data available and made recommendations on future research priorities, with emphasis on the following areas: (I)...

INTRODUCTION AND OBJECTIVE Prevention of tick borne diseases in forestry workers is essentially based on the use of appropriate clothing. The objective of this pragmatic, randomized, controlled trial was to assess the potential benefit of permethrin-treated working trousers for the prevention of tick infestation during forestry work. MATERIALS AND METHODS N=164 male forestry workers were equi...

This proposal represents the cooperative efforts of the international tick research community to develop the first large scale genomic analysis of a medically significant tick, namely Ixodes scapularis. Ticks transmit the greatest variety of human and animal pathogens of any arthropod vector and are second only to mosquitoes as vectors of human disease (Fivaz et al., 1992; Sonenshine and Mather...

Tick-pathogen-host interactions have been closely studied to understand the molecular mechanisms of pathogen transmission for tick-borne diseases, including Lyme disease, babesiosis, spotted fever diseases, and Tick-borne encephalitis, among others. Such studies have yielded insights into disease processes and have identified promising candidates for vaccines against tick-borne diseases (Dai et...

In “Methicillin-resistant Staphylococcus aureus Necrotizing Pneumonia,” by Monica Monaco et al., an error occurred on page 1647, in the first full sentence of the third column. The sentence should read “On day 3 of admission, antimicrobial drug therapy was changed to linezolid (600 mg 2 times a day).” The corrected text appears in the online article at http://www.cdc.gov/ncidod/EID/vol11no10/05...

In our experience with Greyhounds over the past 17 years, the prevalence of TBDs has decreased markedly, likely due to better tick control. For example, 15 years ago approximately half of the retired racing Greyhounds evaluated as potential blood donors at OSU tested positive for Babesia canis or Ehrlichia canis serology, whereas now only 1-3% of the dogs are positive for any TBD. However, in s...

Several important human diseases worldwide are caused by tick-borne viruses. These diseases have become important public health concerns in recent years. The tick-borne viruses that cause diseases in humans mainly belong to 3 families: Bunyaviridae, Flaviviridae, and Reoviridae. In this review, we focus on therapeutic approaches for several of the more important tick-borne viruses from these 3 ...
