Over the early 1920s, several researchers in Avery's laboratory at Rockefeller Hospital turned their attention to certain bacteria, such as Bacillus influenzae, which had previously only been grown in media containing blood or blood derivatives. Because of this, the bacteria were termed "hemophilic." In this fourth article resulting from a long series of studies on bacterial nutrition that Avery conducted, first with Thjotta and then Hugh Morgan, the scientists found that the presence of unheated plant tissue in the media resulted in a remarkable acceleration in the growth curve of pneumococcus, and resulted in longer-lived cultures of the bacteria.
