Résumé
The objective of this study was to test the hypothesis that the paralysis ticks, Ixodes holocyclus and Ixodes cornuatus, are epizootic and/or enzootic in the Greater Melbourne Area (GMA). We examined the ticks in the museum collections of Australia, wrote to, phoned and visited veterinarians and other colleagues in the GMA to gather information about the cases of tick paralysis and to request the ticks for identification. We present evidence of I. holocyclus at 24 postcodes and I. cornuatus at 28 postcodes in the GMA. We found evidence that I. holocyclus is epizootic at four postcodes in the GMA: at East Melbourne, Williamstown, Moonee Ponds and Hoppers Crossing. We did not find evidence that I. holocyclus is enzootic in the GMA. I. cornuatus is apparently enzootic in the GMA at Bullengarook, Kinglake, Chum Creek and Healesville. Our hypothesis is that I. cornuatus is also enzootic at Mt Macedon, Gisborne and at other bushy postcodes in the GMA. Since this tick is apparently enzootic in the GMA, it may also be epizootic at postcodes adjacent to busy postcodes such as Bullengarook, Kinglake, Chum Creek and Healesville. The concept of hitch-hiker larvae, nymphs and adult female ticks may explain many of the cases of tick paralysis due to I. holocyclus in the GMA. The accurate assessment of the risk of tick paralysis in dogs and cats in the GMA requires a more detailed map of the distribution of I. holocyclus and I. cornuatus in Victoria.
