Mycobacterium tuber- culosis bacteria

False-colour scanning electron micrograph, SEM, of the rodlike bacteria Mycobacterium tuberculosis, causative agent of tuberculosis in humans. These bacteria may occur as filamentous branching organisms. They are inhaled into the lungs where they form a primary tubercle, nodular lesion. They then spread to the nearest lymph nodes. This form is called pulmonary tuberculosis or consumption & phthisis (wasting). Many people are infected with- out showing symptoms, the bodys immune system holds the disease in check. They remain carriers, transmitting the bacilli by coughing or sneezing. Infected cows milk may also transmit the bacilli. Magnification: x2925 at 35mm, x5850 at 6x7cm size

EDITORS COMMENTS
This print from Science Photo Library showcases the intricate details of Mycobacterium tuberculosis bacteria, the causative agent of tuberculosis in humans. In this false-color scanning electron micrograph (SEM), we can observe the rodlike structure of these bacteria, which sometimes appear as filamentous branching organisms. When inhaled into the lungs, these tiny invaders form primary tubercles, nodular lesions that mark the onset of pulmonary tuberculosis or consumption and phthisis (wasting). From there, they spread to nearby lymph nodes, causing further complications. Interestingly, many individuals become infected without exhibiting any symptoms; their immune systems successfully keep the disease at bay. However, these carriers unknowingly transmit the bacilli through coughing or sneezing. The transmission is not limited to human-to-human contact alone; even infected cow's milk may serve as a medium for spreading these dangerous bacteria. The magnification level used for capturing this image was an astounding x2925 at 35mm and x5850 at 6x7cm size. Through this mesmerizing visual exploration into microbiology and bacteriology, we gain a deeper understanding of how Mycobacterium tuberculosis operates within our bodies. This photograph serves as a reminder of both the complexity and resilience displayed by microbes while highlighting ongoing efforts to combat one of humanity's oldest foes - tuberculosis.
