25 Questions
What is one of the functions of the capsule of bacteria as mentioned in the text?
It protects the bacteria against phagocytosis
Which staining technique is mentioned in relation to the capsule of bacteria in the text?
Gram staining
How does the capsule of bacteria contribute to bacterial pathogenicity?
By increasing susceptibility to antibiotics
What effect can the absence of a capsule have on bacterial survival?
Increases susceptibility to phagocytosis
In what way does the capsule of bacteria impact host immune response?
Activates complement cascade
Which type of organism is a Protoplast?
Gram-positive bacterium without a cell wall
How does L-form differ from Mycoplasma in terms of cell wall reversion?
L-form can revert its cell wall, Mycoplasma cannot
What is the main cause of induced deficient cell wall in bacteria?
Failure of cell wall synthesis by antibiotics
In which type of medium can Mycoplasma survive?
Any media
What distinguishes Spheroplast from Protoplast?
Spheroplast is Gram-negative without a cell wall, Protoplast is Gram-positive without a cell wall
What type of genetic material is transferred during bacterial conjugation?
Deoxyribonucleic Acid (DNA)
Which type of bacterial cell acts as the donor during conjugation?
F+ cell
What is the term for the structure through which DNA is transferred during conjugation?
Sex pilus
How many cells are involved in the transfer of genetic material during conjugation?
Two cells
What is the nature of genetic material transfer during conjugation?
Nonreciprocal
What type of reproduction is unique to bacteria?
Binary fission
What is the main difference between binary fission and mitosis?
Binary fission does not involve chromosomes, while mitosis does
What happens to the genetic material during binary fission?
It is duplicated and evenly distributed between the daughter cells
What is the term for the time it takes for a bacterial cell to divide into two daughter cells?
Generation time
How does binary fission contribute to antibiotic resistance in bacteria?
Binary fission increases the number of bacteria, which increases the chances of mutations leading to antibiotic resistance
Which bacteria requires the highest percentage of CO2 for growth?
Brucella abortus
Which statement about CO2 requirements of bacteria is incorrect?
Brucella abortus requires less than 5% of CO2 for growth
Which of the following bacteria does NOT require a high percentage of CO2 for growth?
Escherichia coli
Which of the following is a true statement about CO2 requirements of bacteria?
Brucella abortus and Neisseria gonorrhea are examples of bacteria that require high percentage (5 - 10%) of CO2
Why is it important for some bacteria to have a high percentage of CO2?
For growth and survival
Test your knowledge on bacterial cell wall deficiency, including Mycoplasma, Protoplast, Spheroplast, and L-form bacteria. Learn about the importance of the bacterial cell wall and differences between various types of bacteria with deficient cell walls.
