In a world where news articles claim that your water bottle has more bacteria than a toilet seat, it's natural to worry about microorganisms making you sick. However, it’s important to embrace the microbial world around us because they play crucial roles in our lives, and without them, we would be in bad shape. So, in this episode of the Joyful Microbe podcast, we’re covering how to appreciate microbes while maintaining a healthy respect for them.

For this topic, I wanted to discuss these ideas with someone who understands them well, which brought me to Dr. Sandra Wilks. She is a researcher specializing in infection prevention and control, specifically focusing on the contamination of medical devices. Here, we discuss how to enjoy the microbial world around us without fear.

With her vast knowledge and genuine enthusiasm, she shares her journey from childhood curiosity to a passion for microbiology. Sandra's fascination began with tools like magnifying glasses and a microscope, allowing her to discover unseen microorganisms on leaves, moss, and in pond water. She was captivated by the diverse communities of diatoms, amoebas, and other microscopic life forms. This curiosity grew during her time at the British Antarctic Survey, where she explored samples from icy seas and deepened her understanding of marine microbiology. She then went on to complete her PhD in marine microbiology.

Over the years, Sandra's research expanded to include various aspects of microbiology, such as animal waste, sewage, drinking water, food, and everyday surfaces. Her current focus lies in studying the contamination of medical devices and the microbial environments in hospitals and beyond.

Join us as we uncover misconceptions about what “dirty” actually means, appreciate the wonders of the microbial world, and learn to responsibly share our world with these invisible organisms that shape our lives, whether we realize it or not.
