This unprecedented occurrence, believed to be the world’s first recorded instance of a live worm inhabiting the human brain, has raised questions about zoonotic infections and the significance of food handling practices.

In what’s believed to be a world first, doctors in Australia have found an 8-centimetre or 3-inch live parasitic worm living in a 64-yr-old woman’s brain.

The surgeon who removed the worm said: “”I’ve only come across worms using my not-so-good gardening skills… I find them terrifying and this is not something I deal with at all.”

The discovery prompted a swift investigation into the identity of the parasite. Collaborating with an animal parasitology expert from a nearby governmental scientific research agency, Canberra Hospital infectious disease expert Sanjaya Senanayake unveiled the creature’s true nature.

The live worm was identified as Ophidascaris robertsi, a roundworm commonly found in pythons.

The patient resided in proximity to a lake area inhabited by carpet pythons in southeastern New South Wales.

Although she hadn’t directly interacted with these reptiles, it is speculated that the woman ingested the roundworm through the consumption of foraged Warrigal greens, a native leafy vegetable.

A snake’s faeces could have potentially contaminated the vegetation, leading to cross-contamination during cooking or consumption.

The patient’s ailment initially presented as abdominal pain and diarrhoea, evolving into a persistent dry cough, fever, and night sweats. Over time, her symptoms escalated to include forgetfulness and depression, prompting her referral to a hospital in the Australian capital.

Senanayake highlighted the broader implications of zoonotic infections, underscoring the encroachment of human habitats into animal territories.

The incident emphasises the increasing opportunities for interactions between humans, domestic animals, and wildlife, potentially leading to the transmission of diseases.

Senanayake cautioned that while the Ophidascaris infection does not transmit between humans, the prevalence of zoonotic infections, such as coronaviruses, necessitates greater vigilance.

The incident serves as a reminder of the risks associated with foraging and the importance of maintaining hygienic practices.

Proper hand hygiene and thorough washing of foraged materials used in cooking or salads are crucial to prevent contamination.
