Chlamydia trachomatis is a gram-negative bacterium that can replicate only within a host cell. Over the course of the C. trachomatis life cycle, the bacteria take on two distinct forms. Elementary bodies are 200 to 400 nanometers across, and are surrounded by a rigid cell wall that allows them to survive outside of a host cell. This form can initiate a new infection if it comes into contact with a susceptible host cell. Reticulate bodies are 600 to 1500 nanometers across, and are found onl… WebChlamydia species have genomes of approximately 1 to 1.3 megabases in length. ... This form is covered by a rigid cell wall and contains a DNA genome with a molecular weight of 66 × 107 (about 600 genes, one-quarter of the genetic information present in the DNA of Escherichia coli). It also contains a cryptic DNA plasmid with 7,498 base pairs. WebGram-positive bacteria have a thick peptidoglycan layer in their cell wall, which retains the crystal violet during Gram staining, resulting in a purple color. Gram-negative bacteria have a thin peptidoglycan layer which does not retain the crystal violet, so when safranin is added during the process, they stain red. ove 48 shower door
