Insights

This case study details the first probable neurobrucellosis diagnosis in Australia, affecting a feral pig hunter. Prompt treatment with multiple antibiotics led to a positive clinical outcome.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Public Health

Background:

  • Brucellosis is a zoonotic infection with potential neurological complications.
  • Neurobrucellosis is rare but serious, requiring prompt diagnosis and treatment.
  • Australia has previously not documented cases of neurobrucellosis.

Observation:

  • A young adult feral pig hunter presented with neurological symptoms.
  • Symptoms included episodic left-sided visual loss, numbness, and headache.
  • The patient's history suggested potential exposure to Brucella species through feral pigs.

Findings:

  • The patient was diagnosed with probable neurobrucellosis.
  • Treatment involved a combination of intravenous ceftriaxone and oral rifampicin, doxycycline, and trimethoprim–sulfamethoxazole.
  • The patient showed a good clinical response to the prescribed antibiotic regimen.

Implications:

  • This case highlights the importance of considering neurobrucellosis in patients with relevant exposure history and neurological symptoms.
  • It underscores the need for increased awareness and diagnostic vigilance for this condition in Australia.
  • Effective multi-drug therapy can lead to favorable outcomes in neurobrucellosis cases.
