 Item No. SCP-1429 Object Class, Euclid Special Containment Procedures All instances of SCP-1429 are stored in BioSight 66 in Facility A-1429. Free instances are to be kept in individual labeled vials in BioContainment Locker 1429. SCP-1429 is considered to be a Class III infectious disease. In the case of a broken container, all present personnel are to restrict themselves to the area and call for the nearest re-containment team. Personnel assigned to SCP-1429 are to be made aware that there is no way to detect SCP-1429 before manifestation, and they will be quarantined until an escaped instance is recovered. No instances of SCP-1429 should be extracted except for approved testing. Test subjects for SCP-1429 are to be kept in quarantine in specialized human containment suites for the duration of their infection. Upon the manifestation of SCP-1429-B, human test subjects are to be terminated with minimal physical trauma and autopsy for study. When study of a given SCP-1429-B appears unlikely to yield further useful information, instances to be destroyed and SCP-1429 to be recovered. Testing is not to be undertaken without a secure enclosure prepared for any eventual instance of SCP-1429-B. Enclosures must possess multiple angles of surveillance and a freshwater source. See Document 1429-3A for full requirements. Description SCP-1429 is a large luminescent amoeboid organism, approximately 5mm in diameter, of fluorescent blue coloration and unknown origin. Currently, nine instances of SCP-1429 are in the Foundation's possession, and one has been destroyed through testing. After an incubation period, SCP-1429 causes acute and variable mutation in human tissue. SCP-1429 does not share physical characteristics with any known terrestrial microorganisms and does not appear to have a detectable DNA structure. SCP-1429 does not appear to breed or multiply. When an infection, an instance of SCP-1429, will enter a human body painlessly through the skin and settle within a large internal organ, rooting itself and become effectively undetectable by conventional means. The time between infection and activation varies greatly, with test subjects displaying incubation time between 38 minutes and 8 months to 2 weeks. After this period of time, the instance of SCP-1429 becomes active and causes a series of radical mutations to the infected organ through an unknown process. The organism produces a luminescent web of tissue, similar to the nervous tissue around itself approximately 1 cm in diameter, somewhere within the mutated organ. Organs undergo genetic and morphological changes and become ambulatory, growing limbs and simple bodily systems of their own, effectively becoming independent organisms. These organisms were classified as SCP-1429-B. SCP-1429 will remain lodged within SCP-1429-B until the latter's death, after which they will remain for a short period of time before escaping. Instances are capable of repeatedly infecting new hosts if given the opportunity. No two infections have had exactly the same result. Discovery All instances of SCP-1429 were discovered after a series of outbreaks in the central United States over the course of two months. In total, 10 civilians have become infected with 10 individual instances of SCP-1429 and subsequently perished. As per a protocol, a standard media purge will undertake into the contained public knowledge of the events. Additionally, the remains of civilian victims were retrieved and replaced with false bodies. Live in the ceased wild instances of SCP-1429-B were extracted and put in containment for study. Dissection and instance of SCP-1429 were recovered from each recovered instance of SCP-1429-B. Researchers into the victim's personal histories revealed a shared skydiving trip approximately 22 days before the first death. Proposals concerning the examination of the Earth's upper atmosphere are pending. Select testing summaries. In 85% of test cases, the instance of SCP-1429-B succeeded in exiting the host's body, often by breaking through the skin. In 12% of test cases, SCP-1429-B remained trapped within the body and caused fatal internal damage to the host. The remaining 3% of tests yielded unique responses and subjects due to the placement of SCP-1429 and the nature of the subsequent mutation. A selection of testing summaries have been compiled below. This list contains instances of SCP-1429-B encountered through standard testing and not instances recovered from the field. Test number, incubation, affected organ, result, 1429-B. 001, 5 days, 4 hours, 3 minutes, liver. Hosts collapsed in pain as organ began to emulate violently. Organ tore skin and exited the torso before fully converting, causing fatal internal and external trauma. 1429-B 001 manifested 10 bonus legs of equal strength in a simple gut, with a beaked mouth replacing the hepatic vein. Instances capable of herbivorous aquatic life in a freshwater environment. 002, 19 days, 19 hours, 42 minutes, small intestine. Hosts collapsed with sudden, extreme nausea and vomited entire contents of bowel, went in the shock as intestine began to ambulate. Autopsy revealed significant internal bruising where organ detached itself from blood vessels and digestive tract. 1429-B 002 escaped through the host's mouth after its death by cardiac arrest. Upon expulsion, instances had grown several dozen pairs of muscular lobe fins along its sides, as well as a two-circular mouth on the front end. Later developed simple eyes and antenna along its back. Instances proved highly carnivorous and amphibious. 004, 8 days, 1 hour, 7 minutes, right lung. Hosts began internal hemorrhage and suffocated his left lung filled with blood. Autopsy released trapped instances of SCP-1429-B. 1429-B 004 escaped the thoracic cavity during autopsy. Instances had developed a simple muscular web over its surface and a pair of delicate wet wings and was capable of limited jumping and gliding action, accidentally destroyed by surprise coroner's aid as it leapt from the thoracic cavity. 005, 28 days, 2 hours, 58 minutes, heart and circulatory system. Instances collapsed from sudden cessation of blood pressure to the brain. Instances detached itself from the host and escaped through the navel, causing extreme damage to thoracic cavity. 1429-B 005 consisted of heart and a majority of the circulatory system. Instances possessed muscular webbing with a high-level articulation in larger veins and arteries. Finer veins and arteries apparently served as sensory organs. Instances with predatory having developed a small beak within the inferior vena cava and a simple gut, hunted by ambushing prey, anchoring itself and ripping off pieces of flesh before fleeing. 007, 22 hours, 37 minutes, tongue. Hosts began producing inarticulate vocalizations and attempted to bite tongue off as 1429-B began to ambulate. Hosts was sedated to foster the remainder of conversion, died of hemorrhage caused by SCP-1429-B 007 detaching itself. Hosts inflicted by host prevented the anterior half of 1429-B 007 from completing conversion. Instances possessed four pairs of boneless muscular limbs and no other mutations. 008, 82 days, 7 hours, stomach. Hosts complained of unusually intense stomach ache before vomiting blood, expiring from blood loss soon after. 1429-B 008 escaped through the host's mouth. Hosts developed several segmented muscular arms and a complex mandible complete with teeth. Instances of coniferous and retained for study, see attached photo. 01, 15 days, 6 hours, 11 minutes, left eye. Hosts complained of sudden blindness and pain around her eye. Within 4 minutes, ocular muscles had dislodged from the face and the instance of 1429-B escaped the skull. Event proved non-fatal to host. 1429-B 011 possessed three two-jointed limbs which had erupted from its posterior. Instances dried out in 48 hours and pairs with the systems. 015, 13 months, 6 days, 11 minutes, nervous system. Hosts complained of hallucinations, both auditory and visual, and phantom pain and non-existing extremities, was unable to clearly articulate the content of hallucinations. Hosts required outside assistance to escape the host.
