Tuberculosis vaccine bacteria, SEM
Tuberculosis vaccine bacteria. Coloured scanning electron micrograph (SEM) of the Gram-positive rod-shaped (bacillus) Mycobacterium bovis bacteria. This is the BCG (bacillus of Calmette- Guerin) strain of the bacteria, used in the vaccination for tuberculosis (TB). The bacteria is live but attenuated (weakened) in the vaccine. The vaccine primes the immune system, without causing disease, so that it responds more rapidly if infected with TB bacteria. Magnification: x14, 800 when printed 10 centimetres wide

EDITORS COMMENTS
This print showcases the Tuberculosis vaccine bacteria, specifically the Mycobacterium bovis strain known as BCG (bacillus of Calmette-Guerin). In this coloured scanning electron micrograph (SEM), we can observe the Gram-positive rod-shaped bacilli in stunning detail. The BCG strain used in tuberculosis vaccination is live but attenuated, meaning it has been weakened to prevent causing disease while still stimulating a robust immune response. This vaccine serves as a primer for our immune system, allowing it to react more swiftly and effectively if exposed to TB bacteria. With a magnification of x14,800 when printed at 10 centimetres wide, this image offers an up-close look at these protective cells. The false colouring applied enhances their visual impact and highlights their biological significance. As tuberculosis remains a significant global health concern, understanding the biology and medicine behind its prevention is crucial. This SEM image provides valuable insight into the bacterium responsible for this infectious disease and how science aims to combat it through immunization. Captured by Science Photo Library's skilled photographers using advanced scanning electron microscopy techniques, this photograph not only celebrates scientific discovery but also reminds us of the ongoing efforts in medical research towards safeguarding public health worldwide.
