Characterisation of common hypothetical surface peptides between protozoan parasites (Perkinsus olseni) originating from different geographical locations.

Perkinsus olseni and P. marinus are classified as notifiable pathogens by the World Organisation for Animal Health and are known to cause perkinsosis in a variety of molluscs globally. Mass mortalities due to these parasites in farms and in the wild have been a recurrent issue.

Honeybee venom and melittin suppress growth factor receptor activation in HER2-enriched and triple-negative breast cancer.

Despite decades of study, the molecular mechanisms and selectivity of the biomolecular components of honeybee () venom as anticancer agents remain largely unknown. Here, we demonstrate that honeybee venom and its major component melittin potently induce cell death, particularly in the aggressive triple-negative and HER2-enriched breast cancer subtypes. Honeybee venom and melittin suppress the activation of EGFR and HER2 by interfering with the phosphorylation of these receptors in the plasma membrane of breast carcinoma cells.

Histopathological analysis and in situ localisation of Australian tiger snake venom in two clinically envenomed domestic animals.

Objective: To assess histopathological changes in clinically envenomed tiger snake patients and identify tissue specific localisation of venom toxins using immunohistochemistry.

Samples: One feline and one canine patient admitted to the Murdoch Pet Emergency Centre (MPEC), Murdoch University with tiger snake (Notechis sp.) envenoming.

Development of a sensitive enzyme immunoassay for measuring taipan venom in serum.

The detection and measurement of snake venom in blood is important for confirming snake identification, determining when sufficient antivenom has been given, detecting recurrence of envenoming, and in forensic investigation. Venom enzyme immunoassays (EIA) have had persistent problems with poor sensitivity and high background absorbance leading to false positive results. This is particularly problematic with Australasian snakes where small amounts of highly potent venom are injected, resulting in low concentrations being associated with severe clinical effects.
