マクロビオツス

Species name: Macrobiotus sp.
東京都　下水道局

大きさは0.2～1.0mmくらい。体はうすいキチン質の膜でおおわれ、棘剛毛、よろい板を持っている。四対の歩脚があり、先端部に爪がある。口と肛門の付近に、それぞれ線がある。本来は土壌中に生息する生物である。卵を脱皮した皮の中に多数個生む。動作はのろく、ゆっくり歩く姿がクマに似ているのでクマムシと呼ばれる。エサに口から出した歯針を刺し込み、咽頭の働きにより内容物を吸引する。ビデオでは出産が、みられる。

Human-Pathogen Interaction

Species name: Human-Pathogen
Stanford University　Stanley Falkow

Ninety percent of the cells humans carry are microbes. Only a few of the bacteria we encounter are pathogenic and can cause disease. Pathogens possess the inherent ability to cross anatomic barriers or breach other host defenses that limit the microbes that make up our normal flora. A significant part of human evolution has gone into developing ways to thwart microbial intrusion. In turn, microbes have come up with clever ways to avoid and circumvent host defenses but human — microbe interactions is still a "Work in Progress." When we study pathogens we learn as much about ourselves as we do about them.

Part 1: Biology of Plant Virus Infection

Donald Danforth Plant Science Center　Roger Beachy

This seminar describes the cell and molecular biology of plant virus infection. The first lecture will discuss how virus replication centers are set up in plants and how viruses use host cell mechanisms to facilitate cell to cell movement and eventual pathogenesis.

Part 2: Helicobacter pylori and Gastric Cancer

Species name: Helicobacter pylori
Stanford University　Stanley Falkow

Helicobacter pylori lives in the human stomach. It causes gastritis, ulcer disease and even gastric cancer. Some H. pylori can inject a protein, CagA, into gastric epithelial cells. CagA interacts with the tight junctions that bind cells together and with signaling molecules affecting motility and proliferation. CagA is associated with ulcer disease and cancer but we don't understand how it works to favor malignancy. Not long ago in history most humans carried H. pylori ; the incidence of carriage and gastric cancer is dropping but there is evidence that this microbe also had a protective effect on human health.

奈良先端科学技術大学院大学　小林 和夫

Small moving clusters of wild-type strain cells on a 1.5% agar plate. The wild-type strain was spotted on a 1.5% agar plate and incubated at 37°C for 6 h. Coverslips were placed directly onto the surface of the leading edge zones of the colonies and cell morphology observed under a video light microscope. The movie is real time. Scale bar, 20 μm.
