Gram Negative Rods and Cocci Bdellovibrios. Bdellovibrios  are aerobic Gram-negative, curved rods that prey on other bacteria.  The organism attaches to the surface of a bacterium, rotates, and bores a hole through the host cell  wall. It then takes biochemical control of the host cell and grows in the space between the cell wall  and plasma membrane. The host bacterium is killed in the process. The comma-shaped  Bdellovibrio  bacteriovorus  is the most thoroughly studied species of the group.  Pseudomonads. Pseudomonads  are aerobic, Gram-negative rods that are motile with polar  flagella. Over 30 species are found in the group, and  Pseudomonas fluorescens  is a well-known  producer of a yellow-green pigment. Another species,  P. aeruginosa , causes urinary tract infections  and infections of burned tissue.  Azotobacter   and  Rhizobium   . Species of

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
