Proteus - L-Phase durch Penicillineinwirkung

With Proteus the action of higher concentrations of penicillin leads to the formation of the so-called L-phase. First small round structures emerge from the bacterial rods, rapidly enlarging to spheroplasts. These grow into "amoeboid" structures in which vacuoles develop. The spheroplasts multiply and in some places grow deeply into the culture medium where they form the so-called L-colonies. When the penicillin action is suspended there is a gradual regression of the described events and gradually rod-like structures develop again which divide transversely. A stable L-phase may also develop where this regression can no longer occur. Its multiplication is demonstrated. The results of quantitative evaluation are described in detail in the accompanying text.

Proteus - Hemmungsformen durch Penicillinwirkung

All species of Proteus show numerous morphological changes under low concentrations of penicillin, due to inhibition of cell wall synthesis, namely unusually long or thick threads, sometimes with protuberances, large round mobile or immobile bodies, and branching threads. The long threads sometimes form rotating spirals, the round or branching structures also sometimes show rotatory movement. The flagellae of the bacteria become well visible in the phase contrast microscope owing to their greater thickness. The synchronisation of their movements is clearly visible. The flagellae are increasingly cast off. Their aggregation to flagella plaits is easily seen. The results of quantitative evaluation are described in detail in the accompanying text.

Otis tarda (Otididae) - Schlüpfen

The film shows the hatching of two bustard chicks in the incubator. The hole in the shell made by the egg tooth is systematically enlarged. With jerkey movements, the chick undermines the shell layer until the flat pole of the egg is finally broken off. After a brief pause, during which the exhausted chick lies still, the chick finally slips from the shell. The down layer, which is wet at the beginning, drys within 30-40 minutes and the chick visibly rests and recuperates from the exertions of hatching.

Chemisch erzeugte Bewegungen isolierter Strukturen von Zellorganellen

Cheimically Induced Movements of Isolaated Structures from Cell Organelles. Cytolysed and extracted stalks from Vorticella contract in the presence of calcium ions. If the calcium ions are removed and replaced with EDTA, the stalks elongate. Cations from invert soaps cause contractions. Rhythmic contractions occur when calcium ions and ATP are both present. Addition of salyrgan induces a state of continuous relaxation, which can be neutralized by adding detergents. This relaxed-state can also be brought about by relaxing factor from mammalian muscles when ATP is persent. Isolated trichocysts elongate when exposed to calcium ions. Their movement is slowed by protamin. In conclusion, the beating frequency of ciliated epithelial cells isolated and extracted from a frog is shown to increase with increasing ATP concentration. Poisoning with salyrgan the movement of these cilia.
