In a shocking medical first, Australian doctors have found a live parasitic roundworm in a woman’s brain. The roundworm, known as Ophidascaris robertsi, is typically found in snakes and is a common parasite in kangaroos and carpet pythons. However, this is the first reported case of the parasite infecting a human.
The discovery was made after the 64-year-old woman began experiencing memory lapses. Doctors performed an MRI scan, which revealed an “atypical lesion” at the front of her brain. Upon further examination, they found an eight-centimeter roundworm.
Dr. Hari Priya Bandi, the operating surgeon, described the shocking discovery, saying, “Everyone was shocked. And the worm that we found was happily moving, quite vigorously, outside the brain.” The parasite was removed through surgery, and DNA testing confirmed its identity.
The woman had previously been treated for pneumonia but had not fully recovered. She was admitted to the hospital after experiencing abdominal pain, diarrhea, dry cough, and night sweats. Various treatments were tried, but her condition did not improve. Brain scans eventually revealed the presence of the parasite.
Researchers believe that the woman likely contracted the roundworm after coming into contact with a type of native grass called Warrigal greens near a lake. The area where she lived is also home to carpet pythons. As human populations expand and encroach on animal habitats, cases like this may become more common.
While the woman’s case is the first reported instance of Ophidascaris in humans, experts predict that more cases will be recognized in the future. Dr. Sanjaya Senanayake, an infectious disease expert, commended the patient for her patience and courage throughout the process.
As we continue to inhabit areas that were once solely inhabited by animals, it is important to recognize the potential for cross-species infections. Similar cases have occurred in the past, such as with the Nipah virus and various coronaviruses. By understanding these risks, we can better protect ourselves and prevent future infections.
