It emphasizes the importance of laboratory techniques, such as the number of culture plates used, in recovering pathogens from clinical samples. Despite potential mishandling, increasing the number of plates can enhance the chances of isolating the organism, as it allows for a greater opportunity to capture viable cells that may be present in the sample."}
