Guillain-Barré Syndrome Outbreak: The Role of Anti-Ganglioside Antibodies Testing
A recent outbreak of Guillain-Barré Syndrome (GBS) in Pune, India, has seen approximately 160 reported cases since early January. The outbreak has been linked to Campylobacter jejuni, a foodborne pathogen and one of the leading causes of GBS worldwide [1].
Understanding Guillain-Barré Syndrome and Its Triggers

GBS is a rare neurological autoimmune disease in which the immune system attacks the peripheral nervous system, causing muscle weakness, paralysis and, in severe cases, respiratory failure. Symptoms begin with tingling or numbness in the hands and feet and progress to loss of mobility. While most patients recover with treatment, mortality rates range from 3% to 13%, depending on access to health care [2].
The Connection Between Campylobacter Jejuni and Guillain-Barré Syndrome
Certain strains of C. jejuni have a sugar-coated outer layer that resembles human nerve cells. This can trigger an immune response known as molecular mimicry, which causes antibodies to attack nerve cells. Because C. jejuni spreads through contaminated food and water, authorities in Pune are containing the outbreak through water testing, promoting safe food practices, and setting up specialized hospital wards.
The Importance of Anti-Ganglioside Antibody Testing for Guillain-Barré Syndrome
Contrary to the BBC article suggesting limited diagnostic options for neurological autoimmune diseases[1], such as, but not limited to, Guillain-Barré Syndrome (GBS), acute motor axonal neuropathy (AMAN) and Miller–Fisher Syndrome (MFS), recent research highlights the continuing advances in diagnostic methods. One of the most recent studies by Kleiser et al. (2024), highlights that antibody testing, including anti-sulfatide and anti-ganglioside markers, continues to evolve and play a role in the identification of immune-mediated nerve damage. The study, which was conducted using our anti-ganglioside immunoblot, also points out that while anti-sulfatide antibodies may not always be highly specific diagnostic markers, their presence can provide insights into the pathophysiology of neurological autoimmune disorders. It also highlights the need for further research to refine diagnostic criteria and improve the accuracy of antibody-based testing for conditions like GBS [3].
Advancing Guillain-Barré Syndrome Diagnosis and Treatment
With recurrent outbreaks worldwide, early and accurate diagnosis is essential. However, prevention remains the most effective tool against GBS, as avoiding infections—especially those caused by C. jejuni—significantly reduces the risk of developing the syndrome. Despite earlier concerns about limited diagnostic as research advances, the link between Guillain-Barré Syndrome and specific anti-ganglioside antibodies becomes increasingly clear, supporting the need for targeted testing. Our company provides reliable anti-ganglioside antibody testing to support clinicians in identifying and effectively managing neurological autoimmune diseases, ensuring faster intervention and improved patient outcomes.
