lipids by intercepting vesicles departing from the Golgi apparatus and by stealing lipid droplets and host lipid transfer proteins. With the nutrients gathered from the host cell, the bacteria can perform glycolysis and the citric acid cycle. The bacteria also have a fully functional electron transport chain (ETC), which includes a Na+ translocating NADH dehydrogenase, cytochrome bd oxidase, and a V-type ATPase. C. felis uses oxygen as its terminal electron acceptor, in which the cytochrome bd oxidase is necessary. The presence of a Na+ translocating NADH dehydrogenase suggests that instead of a proton-motive force, the bacteria uses a sodium-motive force for creating an electrochemical gradient across the plasma membrane. C. felis has also been shown to have a complete pentose phosphate pathway (PPP) and gluconeogenesis pathway, as well as being capable of both creating and degrading glycogen. Genome A bacterial culture was obtained by inoculating fertilized chicken eggs with C. felis. After the strain had gone through several chicken egg passages, the strain went through four passages of McCoy cells before finally being used for genetic analysis. The genome of C. felis was sequenced via whole genome shotgun. Each gene was then annotated by programs BLASTP and FASTA. Programs GenomeGambler, GeneHacker plus, and Glimmer 2.0 were used to predict protein-coding genes. To search from transmembrane proteins, the program SOSUI was used, and tRNAscan-SE for tRNA genes. C. felis has one circular chromosome that consists of around 1,100,00 base pairs. Compared to non-pathogenic organisms, the size of the C. felis is relatively small. The genes that C. felis does possess encode over 1,000 proteins. Many of the genes are highly conserved within the Chlamydia genus. A specific plasmid is also highly conserved among Chlamydia. The plasmid C. felis possess is called pCfe1 and is about 7,500 base pairs long. A recent study has suggested that the plasmid is necessary for pathogenicity, though the exact mechanism is currently unknown. Ecology C. felis was originally discovered in the lungs of cats suffering from pneumonia. C. felis used to be considered a strain of another member of its genus, C. psittaci until it was recognized as a separate species and reclassified as Chlamydophila felis. Chlamydophila felis was then reclassified to Chlamydia felis due to dispute on the taxonomic usage of Chlamydophila, which is still disputed to this day. C. felis is found worldwide. It has been reported to infect humans as well, giving it
