📄 Studies on the structure of a coronavirus avian infectious bronchitis virus

When avian infectious bronchitis virus (IBV) is fixed in formaldehyde, negative stains are able to penetrate the particle and to visualize an internal component. This component is seen as a tongue or flask shaped structure attached at one point to the outer virus membrane. A model yielding transmission patterns similar to the virus has been made. Gradient centrifugation studies on IBV reveal that the RNP is associated with the internal sac.
