I'm no tick expert but I have had some experience/knowledge of them. Many animals carry the tick and it cannot live for long without a host body as it needs the blood supply. eg. kangaroo, possum, dog, wombat. Some animals have a greater tolerance than others, and there are various types of ticks and bacterias that they can spread.
Some ticks caused paralysis and even death in some animals (eg. some breds of dogs). Also, some animals can build up a resistence, whereas others will get progressively more susceptible after each tick infection (eg. German Shepherd dogs).However, in the channel country (around
Birdsville), there are no ticks and so there is no requirement for chemical treatments. This makes them natually "organic" because there is no use of chemicals at all in either their feed or handling.In farming/grazzing areas where the tick does exists, the Kangaroo is one of the worst carriers of the tick and another reason other than fencing why they are considered a pest to lifestock.Even residential areas such as
Sydney are prone to the paralysis tick and dogs, especially pedigrees can die within a few hours of getting a tick. The tick can drop off a moving animal (possums in particular carry them) onto the dog that is chasing them up a tree! or the tick can drop onto a bush or grass that a person or dog can brush up against. The tick quickly burrows itself into the skin and gets right into your blood. The tick will eventually drop off when it is so gorged of blood that it requires no more, but most humans cannot bear the pain and most dogs will die before the tick has got that far.
Depending on how far they have burrowed, there are different techniques. I grew up on the edge of the Kuringai-National Park and our family members did a lot of bushwalking, often bringing
home a stay tick on our bodies. In humans they are quickly felt and farily easily removed with the tweezers and a bit of metho. With dogs, much the same treatment, however you must be careful not to snap off part of the tick if it's deeply burried - you must use a magnifying glass to inspect that you have removed the whole body! Interestingly, my mother lives in
Sydney (on the edge of the Kuring-gai National Park) recently fell prey to the Rocketsa(?) bacteria spread by a tick that lives only on the bandicoot!! Symptoms were no itch, and no initial knowledge that it existed on her body, broke out in red hive like spots on ear then spread down neck then all over body. 3 weeks later she lacked energy, some dizzyness and recognised a problem. At this point bedridden and undiagnosed for some time as a mystery to doctors then more appearances of the symptoms locally and bandicoot discovered in residental areas. Finally sought antibiotics but very sick by this stage. 2mths later, dizzy spells led to suspected "Menears Disease" but MRI and bloodtests did not agree. Now believed to be residual bacteria from tick! WOW.

When I refer to "them" in the paragraph about the Channel Country I am refering to the cattle that are bred there and the beef is certified as "organic".

Hi Michelle,
My father-in-law suffered from the same symptoms you described for your mother. After many months, an astute doctor finally asked him if he'd been "bitten" by a tick recently. As it turned out, my father-in-law had whilst on holiday in the east. He got antibiotics which helped a little, but it took him literally years to get back to normal. Mostly suffered from ongoing dizzyness and fatigue. Hope your mum is feeling better.
Melissa.

The main tick transmitted diseases of concern are Lyme disease caused by an organism called Borrelia and Tick Typhus caused by an organism called Rickettsia australis. Both diseases may have similar symptoms and both can lead to a chronic illness difficult to treat with antibiotics. Q fever may also be tick-transmitted but this is less common.
It is not a good idea to try and use any chemicals to remove a tick as this may cause it to inject more toxin. Removal as stated above with fine-point tweezers or a tick remover is the way to go. When you have removed the tick completely then the site should be treated with some local antiseptic.
If anybody has more specific questions they can contact me directly on clay.golledge@health.wa.gov.au
