Staphylococcus aureus bacteria, SEM
Staphylococcus aureus bacteria, coloured scanning electron micrograph (SEM). These Gram-positive cocci (round) are found on the skin and mucous membranes of humans and many animals. The bacteria are usually harmless, but infections can occur on broken skin or within a blocked sweat or sebaceous gland, resulting in boils, pustules and abscesses. S. aureus can also cause food poisoning, producing toxins that induce vomiting. Certain strains cause the potentially fatal toxic shock syndrome (TSS). Some strains have developed wide-ranging antibiotic resistance, such as methicillin-resistant S. aureus (MRSA), and are hospital pathogens

EDITORS COMMENTS
This print showcases the intricate world of Staphylococcus aureus bacteria, captured through a coloured scanning electron microscope (SEM). These Gram-positive cocci, or round-shaped microorganisms, are commonly found on both human and animal skin as well as mucous membranes. While typically harmless, these bacteria can lead to infections when they enter broken skin or clog sweat or sebaceous glands. The result can be painful boils, pustules, and abscesses. Beyond skin-related issues, Staphylococcus aureus is also known for causing food poisoning by producing toxins that induce vomiting. In more severe cases, certain strains have been linked to toxic shock syndrome (TSS), a potentially fatal condition. Moreover, some strains of this bacterium have developed resistance to various antibiotics over time. Methicillin-resistant S. aureus (MRSA) is one such strain that poses a significant challenge in hospitals as it can cause difficult-to-treat infections. This image not only highlights the beauty within the microscopic world but also serves as a reminder of the complex relationship between humans and microbes. It underscores the importance of proper hygiene practices and infection control measures in preventing bacterial spread and maintaining public health. As we delve into this mesmerizing visual representation from Science Photo Library's collection, we gain insight into the fascinating yet sometimes perilous realm of pathogenic microorganisms like Staphylococcus aureus
