Swarming and complex pattern formation in <it>Paenibacillus vortex </it>studied by imaging and tracking cells
Abstract Background Swarming motility allows microorganisms to move rapidly over surfaces. The Gram-positive bacterium Paenibacillus vortex exhibits advanced cooperative motility on agar plates resulting in intricate colonial patterns with geometries that are highly sensitive to the environment. The cellular mechanisms that underpin the complex multicellular organization of such a simple organism are not well understood. Results Swarming by P. vortex was studied by real-time light microscopy, by in situ scanning electron microscopy and by tracking the spread of antibiotic-resistant cells within antibiotic-sensitive colonies. When swarming, P. vortex was found to be peritrichously flagellated. Swarming by the curved cells of P. vortex occurred on an extremely wide range of media and agar concentrations (0.3 to 2.2% w/v). At high agar concentrations (> 1% w/v) rotating colonies formed that could be detached from the main mass of cells by withdrawal of cells into the latter. On lower percentage agars, cells moved in an extended network composed of interconnected "snakes" with short-term collision avoidance and sensitivity to extracts from swarming cells. P. vortex formed single Petri dish-wide "supercolonies" with a colony-wide exchange of motile cells. Swarming cells were coupled by rapidly forming, reversible and non-rigid connections to form a loose raft, apparently connected via flagella. Inhibitors of swarming (p-Nitrophenylglycerol and Congo Red) were identified. Mitomycin C was used to trigger filamentation without inhibiting growth or swarming; this facilitated dissection of the detail of swarming. Mitomycin C treatment resulted in malcoordinated swarming and abortive side branch formation and a strong tendency by a subpopulation of the cells to form minimal rotating aggregates of only a few cells. Conclusion P. vortex creates complex macroscopic colonies within which there is considerable reflux and movement and interaction of cells. Cell shape, flagellation, the aversion of cell masses to fuse and temporary connections between proximate cells to form rafts were all features of the swarming and rotation of cell aggregates. Vigorous vortex formation was social, i.e. required > 1 cell. This is the first detailed examination of the swarming behaviour of this bacterium at the cellular level.</p
Zürich, Braginsky Collection, B124 : Jacob ben Asher, <i>Tur Orah Hayyim</i> ("Row: Way of Life")
This manuscript by Jacob ben Asher (son of the rabbi and codifier Asher ben Jehiel) contains one of the oldest copies of the Jewish code Arba’ah Turim. The entire work treats all rules of Jewish law concerning prayers and the synagog. This manuscript contains only the first of four parts. The main text is surrounded by many glosses and commentaries; noteworthy is an autograph note by the influential 15th century German rabbi Jacob Weil in Slavic. The manuscript offers variant readings to the standard editions and contains some otherwise unknown Responsa ("rabbinic answers") by the important Rabbi Israel Isserlin (1390-1460).Online Since: 2015-03-1
Romance Literature in Hebrew Language with an Arabic Twist: The First Story of Jacob ben El'azar's Sefer ha-meshalim
Jacob ben El‘azar’s Sefer ha-meshalim (Book of Stories), was written in the first half of the 13th century in Toledo, a place where Arabic, Hebrew and Romance literary traditions had the opportunity to intermingle, most notably in the works of Jewish authors. Ben El‘azar exemplifies the figure of the Jewish author who straddled the diverse traditions of this time and space: he translated works from Arabic into Hebrew and composed original works in Judeo-Arabic and Hebrew. Further, while some Jewish authors of the period, such as Judah al-Ḥarizi, felt a close connection to the Arabic intellectual environment and largely ignored developments in Romance language practices, Ben El‘azar demonstrated an awareness of the Romance milieu without undervaluing his indebtedness to Arabic.Shalom Spiegel Institute for Medieval Hebrew PoetryDepto. de Lingüística, Estudios Árabes, Hebreos, Vascos y de Asia OrientalFac. de FilologíaTRUEpu
