Beginning in the late 1980s, SFF afflicted with tick paralysis have been described in populations from the Atherton Tablelands in Queensland, Australia (8). The tick has been identified as Ixodes holocyclus (7), one of two paralysis ticks found in eastern Australia (9). One main theory has been presented describing why these arboreal animals have been so adversely affected by a tick that is considered to be ground dwelling. As the natural foraging habitat of the SFF is eliminated, the bats are forced to search elsewhere for food. For this reason, the bats have been attracted to the fruit of the lower growing, invasive tobacco bush (Solanum mauritianum); which is native to South America (10). This bush has been found to harbor large populations

During frequent walks through various SFF colonies, caregivers often find bats with ticks still attached. Back at the TBH facility, the tick is removed and anti-toxin is administered. Subsequently they are given intraperitoneal fluid and syringe fed as much juice as they will voluntarily consume. If a pup is latched on to the affected adult, they are separated and the pup is taken to the nursery for hand-rearing.
The adult bat receives continuous supportive care, including syringe feeding. Ideally, the bat should progress from syringe feeding juice to self-feeding from a hanging bottle and finally to consuming whole, cut fruits. Specialized enclosures allow the bat to hang naturally yet feel supported. Multiple 1” plastic boxes are used to modify the habitat to the support need of each specific individual.
The location of a tick bite contributes significantly to prognosis. Bites in the head/neck region will cause paralysis and limit the bat’s ability to eat. Unable to overcome the metabolic deficits, they become progressively weaker and are euthanized. Conversely, a bat bitten on a less critical area such as an extremity will typically begin eating on their own and regain strength. As they gain strength they are moved to progressively larger enclosures to encourage exercise and …show more content…
These pups are usually found alone, not attached to a mother (J.Maclean, per. comm.).There are a number of physical characteristics associated with this syndrome. Bats may manifest one or more of these characteristics to varying degrees of severity. External characteristics include lighter color wiry hair, decreased flexion of the claws causing decreased ability to hang/ambulate (possibly with a claw deformity or absence), abnormal craniofacial growth and the cleft deformity itself, which may manifest as anything from a hole to a complete midline tract. Any bat displaying the full cleft palate deformity is euthanized. Hand rearing has been attempted on several bats that have some of the lesser severities; however, the majority of them were also eventually euthanized.
