Bacterial ribosomes are of 70S type and quite smaller than eukaryotic 80S types. They are made up of 2 subunits, the 50S, and 30S. Their main role is to synthesize bacterial proteins and enzymes. They are target sites for different antibiotics like erythromycin, macrolides, aminoglycosides, etc...
First let us look at the variety of shapes and then let us link that back to how bacteria obtain nutritients by the methods we have just described. The most common bacterial cell shapes are: 1) rod-shaped (usually a cylinder with hemispherical end-caps), bacteria with this shape are call...
Coccobacillus is an intermediate shape between a coccus and a bacillus. Spiral-shaped bacteria can exist as spirillum (plural: spirilla), spirochete, or vibrio. Pleomorphic bacteria vary in shape and size. Bacterial shapes and arrangements

Bacteria display many cell morphologies and arrangements Bacteria display a wide diversity of shapes and sizes, called morphologies. Bacterial cells are about one tenth the size of eukaryotic cells and are typically 0.5'5.0 micrometres in length. However, a few species'for example Thiomargarita namib...

Therefore, we first processed the images so that the cells appear as bright and well-defined shapes that can be easily thresholded and thus tracked. To do so, we converted the images into 32-bit, then we inverted the LUT, and we performed a local background subtraction using a kernel ...
