Conjugation is sometimes called bacterial mating. Is it a form ofsexual reproduction? Explain.
What is the best explanation for why a bacteriostatic treatment might be chosen over a bacteriocidal treatment? Bacteriostatic treatments will eliminate all bacteria while bacteriocidal treatments will only eliminate a portion of the bacteria. Bacteriostatic treatments typically have lower toxicity to the host when compared to bacteriocidal treatments. Bacteriostatic treatments will prevent all bacterial growth, while bacteriocidal treatments will permit some bacterial growth. Bacteriostatic treatments are typically more costly than bacteriocidal treatments.
In a series of infection experiments, a researcher discovers that the ID50 value for the infectious bacterium Parasiticum mucoides is 2,000, and that the ID50 for another infectious bacterium, Donoteatum thisbacterium, is 150. Given these data, a person exposed to 1,000 bacteria of each type would be more likely to be infected by which bacterium?
There is no way to know given the information provided
Both infections are equally likely
Donoteatum thisbacterium
Parasiticum mucoides

Explain your answer. What is the mode of action of bacitracin? How does this influence the types of bacteria it can be used against effectively? What is the mode of action of tetracycline? How does this influence the types of bacteria it can be used against effectively? Describe how populations of bacteria can evolve resistance to antibiotics. In your description, use the terms/phrases: mutation, resistant, sensitive, individuals, populations, natural selection, horizontal gene transfer.arrow_forwardexplain why bacterial conjugation should not be considered sexual reproductionarrow_forward

Which of the following statements best describes future generations of these bacteria? A) They will be produced by sexual reproduction and will be just as susceptible to the antibiotic. B) They will be produced by asexual reproduction and will be just as susceptible to the antibiotic. C) They will be produced by asexual reproduction and will be more resistant to the antibiotic. D) They will be produced by sexual reproduction and will be more resistant to the antibiotic.arrow_forwardWhich of the statements is TRUE about conjugation? a) Plasmid DNA is transferred from a donor (F+) cell b) It may only be performed by competent cells c) DNA is always integrated into recipient chromosome d) It may be specialized or generalizedarrow_forwardHow might conjugation enhance the survival of bacteria?arrow_forward
- Use the following passage to answer 2 consecutive questions. A urine specimen was collected in a container and placed on the central desk for delivery at 10:00 am. The specimen is not sent to the lab until 5 hours later (3:00 pm). The sample time was marked by the central clerk as collected at 4:00 pm. The bacterial species has a generation time of 30 minutes at room temperature. There are 100 bacterial cells/ml at the time of collection (10:00 am). The laboratory will cite a bacterial infection at more than 1000 bacterial cells/ml.arrow_forwardDescribe bacterial conjugation and support your description with a diagram of two bacteria undergoing conjugation.
