This 2008 photograph depicted a Centers for Disease Control and Prevention (CDC) microbiologist, as she was demonstrating how one properly “candles” an embryonated chicken egg, which employs a very bright light that is either placed behind the egg, such as was done throughout history, by using a candle, hence the name, or employing more modern methods, using a powerful lamp placed against the broad end of the egg, as was the case here. In this way, the contents of the egg are revealed through the translucent shell. By using this procedure, she was able to access the viability of each egg used in the isolation of influenza viruses.
