Microbiology: Scientific Figures & Vector Diagrams

A diagram of a typical prokaryotic cell. This diagram, made in Adobe Illustrator, is an improved version of a similar diagram, Prokaryote cell diagram.svg, which was also made by LadyofHats. Besides general appearance changes, this version adds plasmids and pili, and notes that DNA is circular.

This detailed scientific diagram illustrates Lysogenic And Lytic Cycle in the context of Microbiology.

Lysogenic Cycle: 1. The prokaryotic cell is shown with its DNA which is shown in green. 2. The bacteriophage attaches and releases its DNA, shown in red, into the prokaryotic cell. 3. The phage DNA then moves through the cell to the host’s DNA. 4. The phage DNA integrates itself into the host cell's DNA, creating prophage. 5. The prophage then remains dormant until the host cell divides. 6. After the host cell has duplicated, the phage DNA in the the daughter cells activate, and the phage DNA begins to express itself. Some of the cells containing the prophage go on to create new phages which will move on to infect other cells. https://biologywise.com/lytic-cycle-vs-lysogenic-cycle

Schematic diagram of cellular growth (elongation) and binary fission of bacilli. Blue and red lines indicate old and newly-generated bacterial cell wall, respectively. (1) growth at the center of bacterial body. e.g. Bacillus subtilis , E. coli , and so on. (2) apical growth. e.g. Corynebacterium diphtheriae .

Diagram depicting the failure of bacterial cell division in the presence of a cell wall synthesis inhibitor (e.g. penicillin, vancomycin). 1- Penicillin (or other cell wall synthesis inhibitor) is added to the growth medium with a dividing bacterium. 2- The cell begins to grow, but is unable to synthesize new cell wall to accommodate the expanding cell. 3- As cellular growth continues, cytoplasm covered by plasma membrane begins to squeeze out through the gap(s) in the cell wall. 4- Cell wall integrity is further violated. The cell continues to increase in size, but is unable to "pinch off" the extra cytoplasmic material into two daughter cells because the formation of a division furrow depends on the ability to synthesize new cell wall. 5- The cell wall is shed entirely, forming a spheroplast, which is extremely vulnerable relative to the original cell. The loss of the cell wall also causes the cell to lose control over its shape, so even if the original bacterium were rod-shaped, the sphereoplast is generally spherical. Finally, the fact that the cell has now doubled much of its genetic and metabolic material further disrupts homeostasis, which usually leads to the cell's death.
