| investigations on a babesia isolated from scottish sheep. | the pathognomic, serologic and morphometric identity of a babesia sp. recently isolated from sheep in argyllshire was studied. initially, problems were encountered due to the occurrence of eperythrozoon ovis as a contaminant of the isolate and treatment with neoarsphenamine failed to remove it. finally, a combination of oxytetracycline therapy and rapid passage allowed isolation of the babesia sp. and its preservation in the form of a glycerolized, infected blood stabilate. inoculation of the st ... | 1981 | 7329723 |
| distribution of borrelia burgdorferi s.l. spirochaete dna in british ticks (argasidae and ixodidae) since the 19th century, assessed by pcr. | the distribution of borrelia burgdorferi sensu lato, the lyme borreliosis agent, was surveyed in british ticks in the collection of the natural history museum, london. alcohol-preserved specimens of eight species of ticks known to attack humans were studied: ixodes ricinus, i. hexagonus, i. uriae, i. trianguliceps, dermacentor reticulatus, haemaphysalis punctata, rhipicephalus sanguineus and argas vespertilionis. the sample comprised all life stages and originated from a wide range of host speci ... | 1998 | 9513944 |
| natural prevalence of infection with ehrlichia (cytoecetes) phagocytophila of ixodes ricinus ticks in scotland. | ixodes ricinus nymphs and adults were collected from vegetation and from sheep at four sites in scotland typical of areas endemic for tick-borne fever in sheep caused by infection with ehrlichia (cytoecetes) phagocytophila (rickettsiales). the great majority of ticks examined was from woodland sites adjacent to sheep farms where there was a high probability of them feeding on roe deer (capreolus capreolus) in a non-domestic focus of infestation and infection. ticks were examined for infection by ... | 1998 | 9760062 |
| rising burden of immature sheep ticks (ixodes ricinus) on red grouse (lagopus lagopus scoticus) chicks in the scottish uplands. | the sheep tick ixodes ricinus (l.) (acari: ixodidae) is an ectoparasite of major economic and pathogenic importance in scotland. its distribution in the scottish uplands is assumed to be governed by the abundance and distribution of its definitive hosts (deer and sheep) and climatic variables such as temperature and rainfall. as the numbers of its major host in scotland, red deer, have increased dramatically and climatic conditions have become more favourable, the level of parasitism could have ... | 2004 | 15009449 |

| the effect of host movement on viral transmission dynamics in a vector-borne disease system. | many vector-borne pathogens whose primary vectors are generalists, such as ixodid ticks, can infect a wide range of host species and are often zoonotic. understanding their transmission dynamics is important for the development of disease management programmes. models exist to describe the transmission dynamics of such diseases, but are necessarily simplistic and generally limited by knowledge of vector population dynamics. they are typically deterministic sir-type models, which predict disease ... | 2009 | 19631009 |
| altitudinal patterns of tick and host abundance: a potential role for climate change in regulating tick-borne diseases? | the impact of climate change on vector-borne infectious diseases is currently controversial. in europe the primary arthropod vectors of zoonotic diseases are ticks, which transmit borrelia burgdorferi sensu lato (the agent of lyme disease), tick-borne encephalitis virus and louping ill virus between humans, livestock and wildlife. ixodes ricinus ticks and reported tick-borne disease cases are currently increasing in the uk. theories for this include climate change and increasing host abundance. ... | 2010 | 19685082 |
| prevalence, distribution and risk associated with tick infestation of dogs in great britain. | current concerns over the potential impacts of climate change and the increased movement between countries of people and companion animals on the distribution of ectoparasites, highlight the need for accurate understanding of existing prevalence patterns. without these future changes will not be detected. here, the distribution and prevalence of tick infestations of domestic dogs in great britain were examined. a total of 173 veterinary practices were recruited to monitor tick attachment to dogs ... | 2011 | 21418263 |
