Description

A transmission electron micrograph of a diplococcus (renamed Streptococcus in 1974) pneumoniae bacteria. A striking feature of these bacteria is an intra-cytoplasmic membrane system which appears to be an extension of septa in dividing bacteria. Image is related to Figure 3 in J. Cell. Biol. 22:453-467, 1964. Image made available by James D. Jamieson and the Department of Cell Biology, Yale University School of Medicine.
