In terms of microbial pathogenicity, molecular Koch's postulates are a set of experimental criteria that show:
A microbe is the aetiological agent of a disease
A gene encodes a product that contributes to disease
A gene encodes a product that contributes to immunity to a disease
A mutation does not contribute to disease
What is a lawn of bacteria?
an uneven layer of bacteria covering an entire surface
an uneven layer of bacteria covering only part of a surface
a uniform, even layer of bacteria covering an entire surface
a uniform, even layer of bacteria covering part of a surface
Bacteria have three major methods of resisting antibiotics.
They may lack (or modify) the feature that the antibiotic targets, so that the drug has little or no effect.
The may have an enzyme that helps them break down and inactivate the antibiotic.
They may have efflux pumps that remove the drug from the cell.
Which method of resistance are Gram-negatives particularly famous for?
Group of answer choices
target modification
enzymatic breakdown
horizontal transfer
efflux pumps

Give an example of the antibiotic that attack these parts. schematic drawing will do, I can just draw it on my ownarrow_forwardWhich of the following does NOT describe a mechanism of antibiotic resistance among bacteria? enzymes to hydrolyze or chemically alter the antibiotics mutations in target molecules so that antibiotics can no longer bind efflux pumps cell wall diffusion barrier, e.g. Gram-negative outer membrane, Acid Fast cell wall of Mycobacterium O increased synthesis of porins to increase antibiotic diffusion across membranesarrow_forwardWhich statements describe ways in which antibiotic resistant bacteria can spread? Health care workers become infected after have interacting with sick patients. Hospital visitors transfer resistant bacteria from patients to family or community members. Animals raised for meat or milk are routinely given antibiotics. Animal feces is used as a fertilizer for food crops. Antibacterial soaps are used at home, at schools, and in hospitals.arrow_forward

Disease Symptoms vomiting, abdominal pain, coughing, muscular weakness, visual disturbance botulism inflammation of lungs, fever, shortness of breath, fluid in lungs pneumonia typhoid fever red rashes, high fever, intestinal bleeding tetanus uncontrolled contractions of voluntary muscles Which two diseases listed in the table affect the digestive system? Be sure to support your reasoning with evidence from the table. Please write in complete sentences.arrow_forwardThe following graph shows the trends in bacteria and viruses after they infect an organism. Part A: Explain how reproductive differences between these two pathogens attribute to the differences shown in the graph. Identify whether viruses are organisms and describe how this graph supports your claim. Part B: Most antibiotics target the cell wall of a pathogen. Use the graph to explain why antibiotics can be ineffective against some pathogens.arrow_forwardWhat are the flaws ? Prokaryotes can live in many different environments. Anerobic organisms need oxygen to survive, while aerobic organisms can survive without oxygen. Autotrophs are organisms that can assemble high energy macromolecules for their energy. Chemotrophs are organisms that capture energy from light. Extremophiles are organisms that grow in extreme conditions like boiling water. Gram-positive bacteria have few layers of peptidoglycan, while gram-negative bacteria have many layers of peptidoglycan and are surrounded by an outer membrane. Harmful bacteria can cause illness like food poisoning. Helpful bacteria can be used in food production to make yogurt. The endosymbiotic theory states that some of the organelles in eukaryotes were once free living prokaryotes. This is supported by the mitochondria and cytoplasm since they have their own DNA and ribosomes. Harmful protists can cause diseases like malaria in humans and downy mildew in plants. Helpful protists can be…arrow_forward

The B portion remaining would still be able to bind to the target cell, but would not have toxic effects The remaining B portion would enter the cell and carry out its toxic activity, such as ADP-ribosylation The remaining B portion would cause inhibition of protein synthesis Nothing would happen because the A portion is responsible for binding to the target cell.
