Sphingopyxis Italica
''Sphingopyxis italica'' is a bacterium. It is Gram-negative, aerobic, motile, rod-shaped and was isolated from volcanic rock in the Roman catacomb Catacombs are man-made underground passages primarily used for religious purposes, particularly for burial. Any chamber used as a burial place is considered a catacomb, although the word is most commonly associated with the Roman Empire. Etym ...s of Saint Callixtus in Rome. Its type strain is SC13E-S71T ( = DSM 25229T = CECT 8016T). References External links LPSN Sphingomonadales [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gram-negative
Gram-negative bacteria are bacteria that, unlike gram-positive bacteria, do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. Their defining characteristic is that their cell envelope consists of a thin peptidoglycan cell wall sandwiched between an inner ( cytoplasmic) membrane and an outer membrane. These bacteria are found in all environments that support life on Earth. Within this category, notable species include the model organism '' Escherichia coli'', along with various pathogenic bacteria, such as '' Pseudomonas aeruginosa'', '' Chlamydia trachomatis'', and '' Yersinia pestis''. They pose significant challenges in the medical field due to their outer membrane, which acts as a protective barrier against numerous antibiotics (including penicillin), detergents that would normally damage the inner cell membrane, and the antimicrobial enzyme lysozyme produced by animals as part of their innate immune system.

Motile
Motility is the ability of an organism to move independently using metabolic energy. This biological concept encompasses movement at various levels, from whole organisms to cells and subcellular components. Motility is observed in animals, microorganisms, and even some plant structures, playing crucial roles in activities such as foraging, reproduction, and cellular functions. It is genetically determined but can be influenced by environmental factors. In multicellular organisms, motility is facilitated by systems like the nervous and musculoskeletal systems, while at the cellular level, it involves mechanisms such as amoeboid movement and flagellar propulsion. These cellular movements can be directed by external stimuli, a phenomenon known as taxis. Examples include chemotaxis (movement along chemical gradients) and phototaxis (movement in response to light). Motility also includes physiological processes like gastrointestinal movements and peristalsis. Understanding moti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catacomb
Catacombs are man-made underground passages primarily used for religious purposes, particularly for burial. Any chamber used as a burial place is considered a catacomb, although the word is most commonly associated with the Roman Empire. Etymology and history The first place to be referred to as ''catacombs'' was the system of underground tombs between the 2nd and 3rd milestones of the Appian Way in Rome, where the bodies of the apostles Peter and Paul, among others, were said to have been buried. The name of that place in Late Latin was ''catacumbas'' (feminine nominative plural; the singular is ''catacumba'') — a word of obscure origin, possibly deriving from a proper name or a derivation of the Greek phrase ''cata cumbas'', "below the quarries". The word referred originally only to the Roman catacombs, but was extended by the 19th century to refer to any subterranean receptacle of the dead, as in the 18th-century Paris catacombs. The ancient Christians carved the first ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saint Callixtus
Pope Callixtus I (Greek: Κάλλιστος), also called Callistus I, was the bishop of Rome (according to Sextus Julius Africanus) from to his death or 223.Chapman, John (1908). "Pope Callistus I" in ''The Catholic Encyclopedia''. Vol. 3. New York: Robert Appleton Company. He lived during the reigns of the Roman emperors Elagabalus and Alexander Severus. Eusebius and the Liberian catalogue list his episcopate as having lasted five years (217–222). In 217, when Callixtus followed Zephyrinus as Bishop of Rome, he started to admit into the Church converts from sects or schisms. He was killed for being Christian and is venerated as a saint and martyr by the Catholic Church (the patron saint of cemetery workers). Life Callixtus I's contemporaries and enemies, Tertullian and Hippolytus of Rome, the author of ''Philosophumena'', relate that Callixtus, as a young slave from Rome, was put in charge of collected funds by his master Carpophorus, funds which were given as alms by oth ...
