Item #: SCP-XXXX

Object Class: Safe

**Special Containment Procedures: SCP-XXXX samples are to be kept in glass containers not exceeding 30 cubed millilitres of volume. The containers are to be kept at a constant pH of 6.5 in order to provide sub optimal conditions for growth thus slowing the metabolic processes of the SCP-XXXX sample, this allows the sample to only be provided with nutrition every 30 days.

The containers are to be kept at constant refrigeration of temperatures below 5°C to further slow metabolic rates during storage.

However, should SCP-XXXX be required for research it is to be kept at temperatures which do not exceed the human body's optimal 37°C, the sample is also to be provided with a solution of fructose every 12 hours.

Description: SCP-XXXX is a rod shaped mono flagellated motile bacterium measuring approximately 2µm of length and 0.5µm of width. SCP-XXXX's optimal conditions for growth are a pH of 7.4 (approximately that of human blood plasma) and a temperature of 37°C (approximately that of a human body) SCP-XXXX does not seem to be affected by the presence of oxygen as it is able of both anaerobic and aerobic respiration. SCP-XXXX was recovered on ¦¦/¦/¦¦¦¦ in ¦¦¦¦¦ Belgium by Agent ¦¦¦¦¦¦ ¦¦¦¦¦

SCP-XXXX is neither gram positive or negative as it's exterior has a composition not seen before, with a 3 seperate membranes surrounded by 3 cell walls made of an unknown carbon compound, this makes SCP-XXXX almost invulnerable to adverse chemical conditions and physical disturbances making any known antibiotic have no effect on SCP-XXXX cells, allowing the cells to be both air and water borne.

SCP-XXXX's anomalous properties arise when examining its DNA, unlike the majority of prokaryotic cells SCP-XXXX contains highly complex DNA with multiple chromosomes which allow SCP-XXXX to seemingly undertake actions that would otherwise not be possible for an organism of its size.

SCP-XXXX shows a preference for infecting the blood stream and large intestine of humans and primates, showing increased contagion when presented the opportunity to infect a human. SCP-XXXX's interaction with hosts varies greatly on a case by case basis. It is currently unknown how SCP-XXXX selects symbiosis with some hosts and parthenogenesis with others.

Upon entering the bloodstream SCP-XXXX cells will use their motility to colonise the blood plasma of their host, should SCP-XXXX encounter a white blood cell SCP-XXXX will embed itself inside the cell using a 'hook' like projection from its outer membrane, SCP-XXXX will then use an organelle resembling a pilus which will enter the white blood cell and travel to the nucleus, SCP-XXXX is then observed to replace sections of DNA with its own. After this "conversion" the white blood cell and any daughter cells will no longer produce an immune response upon encountering SCP-XXXX and will seemingly treat it as a body cell.

At this stage of infection SCP-XXXX will appear to make a decision on weather to act as a pathogen or probiotic to the host. If the parthenogenesis is chosen, SCP-XXXX cells will attempt to breach the blood brain barrier using enzymes to break the barrier down. Once in the brain the SCP-XXXX cells will reach the central nervous system, here the cells occupy the synaptic clef and are able to induce impulses by producing neurotransmitters and/or blocking existing neurotransmitters. At this point the host begins to [DATA EXPUNGED] in an apparent attempt to spread SCP-XXXX until the termination of the host due to prolonged [DATA EXPUNGED].

However should SCP-XXXX determine the host suitable a portion of the cells will travel to the intestines, here the host's natural microbiome will be eventually terminated by SCP-XXXX, the cells of SCP-XXXX will attack other forms of bacteria by secreting chemicals similar to antibiotics in composition and effect, this will result in the almost complete eradication of any native bacteria inside the host, however should it encounter non SCP-XXXX cells, SCP-XXXX will attack the cells in a similar manner to SCP-XXXX's method of 'converting' white blood cells, however it will instead fully replace the cell's native DNA with a copy of its own. The bacterium will then become a manifestation of SCP-XXXX, it is currently unknown what purpose this serves due to its inefficiency compared to more conventional reproduction methods. Dr ¦¦¦¦¦¦¦ hypothesises that SCP-XXXX may integrate useful components of the bacterium's DNA into its own genome, increasing its diverse range of actions.

Once the cells have fully colonised the host's intestines they will fulfil the function of the hosts previous microbiome, however SCP-XXXX will slowly change the behaviour of the host through unknown means. The host will be drawn to foods containing high concentrations of fructose sugar as well as hosts showing a preference towards crowded areas to spread the bacterium.

SCP-XXXX was also found to plant its DNA inside egg and sperm cells, the exact purpose of this is currently unknown, however because of potential ramifications, should any staff member be benignly effected by SCP-XXXX they are to be made sterile by surgical means.

Currently, due to the nature of SCP-XXXX it cannot be reliably treated once it has infected a host, therefore staff are to handle SCP-XXXX samples and hosts, in hazmat suits fitted with re-breathers.
Should a staff member be infected with SCP-XXXX early signs of parthenogenesis are to be investigated common symptoms include : Cranial swelling, psychosis, frequent internal bleeding and abnormalities in skull topography following advanced stages of infection.

Should a member of staff be found to have pathogenic SCP-XXXX cells they are to be isolated in a sterile room preferably in the on site medical ward. Should advanced stages on infection take place they are to be terminated and cremated at temperatures of at least 850? as these temperatures have been found to be high enough to damage the cell wall of SCP-XXXX, when finished the ashes are to be centrifuged and any DNA found from SCP-XXXX are to be isolated and stored for testing.
