Cancer patients undergoing chemotherapy are normally more susceptible to infections. However, a patient receiving an antitumr drug that inhibited cell division was resistant to Salmonella. Provide a possible mechanism for the resistance.Explanation / Answer
1. The symptoms mentioned in question are due to the tetanus infection caused by the bacteria Clostridium tetani. The women had a wound in her toe and she did not take any medication. Since Clostridium tetani is predominant in soil, it might have caused tetanus in that woman. As a result, she experienced tightness of jaw and facial muscle spasms. Tetanus is also called lock-jaw disease and hence her condition is due to an infection. Tetanus is a non-communicable disease. Hence, she cannot transmit this infection to other people.
2. a. The most probable etiological agent in shrimp associated diarrhoea is E. coli. Strains belonging to Enteropathogenic E. coli mainly causes this type of diarrhea.
2. b. Two people in Vermont suffered from blurred vision and malaise due to an infection caused by the bacteria Clostridium botulinum. They might have ingested the botulinum toxin secreted by this pathogen.
3. Salmonella has the ability to grow in tumor cells. The antitumor drug is ineffective against this bacteria and hence they are resistant.
