Mammalian cell cultures often are used for experimentation. The cell culture medium typically is supplemented with penicillin to prevent bacterial contamination of the cell line. However, researchers know that this antibiotic will not prevent Mycoplasma growth. Explain why penicillin does not protect the culture from Mycoplasma contamination.

The mechanism of pathogenesis by M. tuberculosis starts in the lung alveoli. The cell wall of M. tuberculosis allows it to resist phagocytolysis by the alveolar macrophages, where they can multiply. They can then induce apoptosis in macrophages, which die, and the bacteria is free to infect other macrophages. As the cycle of infection slowly progresses, the body's response to the infection is to try to wall off the bacteria in granulomas (wall of immune cells, both dead and alive, surrounding the bacteria to restrict its spread). Eventually, the bacteria can escape the granuloma and infect other parts of the lung. Transmission of Mtb Initial infection and Granuloma cavitation replication of Mtb in macrophages and dissemination of Mtb in the lung Infected macrophages Caseating granuloma Recruitment of Innate and adaptive immune cells Infected cells undergo necrosis resulting in the…arrow_forwardIn your own words, briefly describe the function of FeSO4 in the KIA medium in one sentence.arrow_forward
