| pathogens in ectoparasites from free-ranging animals: infection with rickettsia asembonensis in ticks, and a potentially new species of dipylidium in fleas and lice. | vector-borne infections are persistent public health threats worldwide. in recent years, a number of mosquito-borne viruses have emerged or re-emerged to cause major disease outbreaks. other vector-borne pathogens, however, remain understudied and much neglected especially in the developing regions of the world including southeast asia. in this study, the brown dog tick rhipicephalus sanguineus sensu lato, cat louse felicola subrostratus, and cat fleas ctenocephalides felis and ctenocephalides o ... | 2017 | 28969827 |
| epidemiological survey of ticks and tick-borne pathogens in pet dogs in south-eastern china. | to understand the epidemiology of tick infestation and tick-borne diseases in pet dogs in south-eastern china and to develop a reference for their prevention and treatment, we collected 1550 ticks parasitizing 562 dogs in 122 veterinary clinics from 20 cities of south-eastern china. dogs were tested for common tick-borne pathogens; collected ticks were identified and processed for the detection of tick-borne pathogens. the use of an in vitro elisa diagnostic kit for antibody detection (snap®4dx® ... | 2017 | 28971797 |
| mutation in the sodium channel gene corresponds with phenotypic resistance of rhipicephalus sanguineus sensu lato (acari: ixodidae) to pyrethroids. | the brown dog tick, rhipicephalus sanguineus sensu lato (latreille), is a cosmopolitan ectoparasite and vector of pathogens that kill humans and animals. pyrethroids represent a class of synthetic acaricides that have been used intensely to try to control the brown dog tick and mitigate the risk of tick-borne disease transmission. however, acaricide resistance is an emerging problem in the management of the brown dog tick. understanding the mechanism of resistance to acaricides, including pyreth ... | 2017 | 28981687 |
