Dr Vanya Gant

Infectious diseases

Medical interests: Infectious diseases, fever in immunodeficient patients, probiotics.



I have been practising ward-based infectious diseases medicine and microbiology for over 20 years. My main interest at work is diagnosing and treating fever in patients with immune deficiencies, mostly due to cancer, treatment for leukaemia or bone marrow transplantation. I am also interested in the emerging evidence that probiotics can and sometimes do work for restoring and maintaining health, and I strongly believe that antibiotics are used far too freely and unnecessarily, sometimes with adverse effects.

Medical training

Dr Vanya Gant studied medicine at the Middlesex Hospital in London and qualified in 1980. He then gained a decade of clinical experience in general hospital medicine, treating patients across several medical specialities. Following three years of intense research, he gained a PhD in cellular immunology and has since then focused his clinical work within the field of microbiology and infectious diseases. He has held the following posts:

Senior Lecturer in Microbiology within Guy’s and St Thomas’ Hospitals: Dr Gant held this post for five years, during which time he established a specialist clinical infection service, delivered at the bedside of patients in intensive care and in HIV inpatient units.

Clinical Director at the University College of London Hospital Trust: during his post at UCLH, he formed the Directorate of Infection.

Current appointments

Dr Vanya Gant is currently Consultant in Microbiology and Infectious Diseases, and is also Divisional Clinical Director at University College London Hospitals NHS Trust, where he is responsible for an inpatient infectious diseases ward, which also houses the United Kingdom’s Hospital for Tropical Diseases. He is also responsible for London’s Tuberculosis Find and Treat Service, a unique London-based outfit which diagnoses TB and ensures treatment completion in the hard-to-access homeless, who are sometimes also drug and alcohol dependent.

Dr Gant is still active in research and has published over 60 papers on academic subjects relating to infection and is currently involved in two research studies funded at over £10 million.
