A patient goes to the doctor with a cold and sore throat and asks for antibiotics. The doctor refuses to prescribe antibiotics because the illness is caused by which of the following pathogens?

Rationale

Viruses are responsible for causing colds and sore throats.

Colds and sore throats are typically caused by viral infections, such as rhinoviruses and coronaviruses. Antibiotics are ineffective against viruses, which is why the doctor refuses to prescribe them in this case.

A (Protist) YOUR ANSWER

Protists are a diverse group of eukaryotic microorganisms, including protozoa and algae, that can cause various infections, but they are not the primary cause of common colds or sore throats. These types of infections are more frequently linked to viral agents rather than protist pathogens.

B (Fungus) YOUR ANSWER

Fungal infections can lead to a range of health issues, including throat infections, but they are not the typical cause of the common cold or sore throat. The symptoms presented in this case align more closely with viral infections than with fungal ones.

C (Virus) CORRECT

Viruses are indeed the causative agents of the common cold and many cases of sore throat. They infect the upper respiratory tract, leading to the symptoms described. As such, they are the correct choice as the reason for the doctor’s refusal to prescribe antibiotics.

D (Bacteria) YOUR ANSWER

Bacterial infections can cause throat issues, such as strep throat, but they are not the typical cause of a cold. The presence of cold symptoms suggests a viral infection rather than a bacterial one, which is why antibiotics would not be appropriate treatment.

Conclusion

In summary, the refusal to prescribe antibiotics is based on the understanding that colds and sore throats are predominantly caused by viral infections, which do not respond to antibiotic treatment. While other pathogens like bacteria, fungi, and protists can cause throat infections, they are not responsible for the common cold, affirming the viral etiology of the patient’s symptoms.
