tick是一種類似跳蚤的昆蟲，體形比跳蚤大的多。
澳洲常見的tick有三種
Paralysis Tick
The Paralysis Tick (Ixodes holocyclus) is the single most dangerous parasite for dogs on the eastern coast of Australia. Just one tick is capable of causing paralysis and death. Dogs may become infected with ticks as they brush through long grass or scrub and without the repellent protection of Kiltix this can lead to serious problems. The Paralysis Tick releases toxin during the feeding which causes a varitey of clinical signs. These include a change in the dog’s bark and wobbly hind legs which, if left untreated, often leads to fatalaties .
The Brown Dog Tick
The Brown Dog Tick (Rhipicephalus sanguineus) is a serious pest of dogs. It is unique in that it can survive for long periods off the host. There can be massive numbers of ticks in a dog’s environment, either in its kennel or even the home, acting as a reservoir for continual re-infestation of the dog if not treated. Brown Dog Ticks can cause “tick worry” with dogs licking and scratching at the attachment sites. In large numbers they can cause anaemia.
The Bush Tick
The Bush Tick (Haemaphysalis longicornis) affects dogs from irritation of the skin to extensive blood loss in heavy infestations. |
