The population dynamics of tick-borne disease agents and in particular the mechanisms which influence their persistence are examined with reference to the flavivirus that causes louping-ill in red grouse and sheep. Pockets of infection cause heavy mortality and the infection probably persists as a
Rapid and precise virus detection procedures are an important component of any epizootiological study. An automated one tube reverse transcriptase and nested primer polymerase chain reaction (RT-PCR) followed by nucleotide sequencing of the cDNA product, was used for the rapid detection and
There has been an emergence and expansion of tick-borne diseases in Europe, Asia and North America in recent years, including Lyme disease, tick-borne encephalitis and human anaplasmosis. The primary vectors implicated are hard ticks of the genus Ixodes. Although much is known about the host
