Salmonella bacterium dividing, SEM
Salmonella bacterium dividing. Coloured scanning electron micrograph (SEM) of of a Salmonella bacterium dividing. The two new daughter cells are seen at upper right and lower left, still joined by a thin connection (centre). Flagella, thin thread-like structures used by the bacteria to move, are also seen. Salmonella bacteria can cause food poisoning when they are eaten in contaminated food such as raw eggs. Given the right conditions, they can multiply rapidly. Symptoms include abdominal pain, nausea, diarrhoea and vomiting

EDITORS COMMENTS
This print showcases the intricate process of Salmonella bacterium dividing. In this false-colored scanning electron micrograph (SEM), we are granted a glimpse into the microscopic world of biology and reproduction. The Salmonella bacterium is seen in all its glory, with two new daughter cells emerging at opposite ends, still connected by a delicate thread-like structure. The presence of flagella, those thin and agile structures used by bacteria for movement, adds another layer of fascination to this image. It's incredible to witness how these tiny organisms navigate their surroundings with such precision. However, behind the beauty lies a potential danger. Salmonella bacteria have gained notoriety as food poisoning culprits when consumed through contaminated sources like raw eggs. Under favorable conditions, they can multiply rapidly and wreak havoc on our digestive systems. Symptoms such as abdominal pain, nausea, diarrhea, and vomiting serve as reminders of the harm these microbes can cause. Understanding their behavior under a microscope allows scientists to develop strategies for prevention and treatment. This photograph serves as a reminder that even within the tiniest corners of nature's realm lie both marvels and threats that impact our daily lives.
