Louis Pasteur's groundbreaking work in bacteriology led to the development of vaccines for various diseases, including hydrophobia. Fast forward to modern times, and macrophages, those versatile immune cells, are now at the forefront of tuberculosis vaccine research. In Transmission Electron Microscopy (TEM) images, we see macrophages engulfing tuberculosis vaccine particles, ready to mount a defense against the bacteria. (Macrophage and tuberculosis vaccine, TEM) The intricate dance of immune response is captured in these images, with macrophages using their phagocytic abilities to neutralize the threat. Vaccinia virus particles, used in some tuberculosis vaccine formulations, are also visible in TEM, showcasing their protective role. (Vaccinia virus particle, TEM) In Scanning Electron Microscopy (SEM) images, we can see the tuberculosis bacteria themselves, their complex structures a testament to the intricacy of microbial life. (Tuberculosis vaccine bacteria, SEM) The macrophage's role in engulfing and neutralizing these bacteria is crucial in the fight against tuberculosis, making these images a powerful reminder of the ongoing battle between our immune systems and microbial threats.
