Explanation / Answer
1. True. Helicobacter pylori is the most common organism found in the human stomach.
2. Clostridium and protists are not found in the GIT of a healthy individual. They cause diseases. The other options consist of the normal flora.
3. Vitamin C and CO2 are not produced by the intestinal flora in the gut. These organisms produce vitamin K and B12.
4. Bacteria make up about _____one third___ the weight of fecal matter.
5. When a person takes an oral antibiotic, the option is - all of the above..
6. Healthcare-associated infections are also called nosocomial infections. These occur when the apparatus used in hospitals is not sterile. The doctor/nurse may also be a vehicle of transmission.
7. All the given healthcare procedures can introduce pathogens into the patient. Catheterization is the introduction of a catheter inside the body. A spinal puncture also opens up the bosy while during surgery, pathogens can easily enter if the operation theatre is not sterile.
8. Infection is the growth of organisms not seen in the body. Virulence is the ability to cause a disease while disease is the symptomatic show of the inner growth of microbes. Pathogenicity is the method of infection.
9. Lipopolysaccharide does not act as a adherens factor. The rest of the options act as adherens factors.
