Capitolo 3, Problema 3
Assume a new enveloped RNA virus is causing an epidemic. Which of the following may be useful to manage the disease? Select all that apply.
a. Injectable antibodies
b. Interferons
c. Antibiotics
d. Nucleoside analogs
Guida verificata passo dopo passo1
Step 1: Understand the nature of the virus. Since it is an enveloped RNA virus, it means the virus has a lipid membrane and its genetic material is RNA, which influences treatment options.
Step 2: Evaluate the use of injectable antibodies (option a). These can provide passive immunity by directly neutralizing the virus, which is often useful in managing viral infections.
Step 3: Consider interferons (option b). Interferons are signaling proteins released by host cells in response to viral infections and can boost the immune response, making them potentially useful against RNA viruses.
Step 4: Assess the role of antibiotics (option c). Antibiotics target bacteria, not viruses, so they are generally ineffective against viral infections unless there is a secondary bacterial infection.
Step 5: Analyze nucleoside analogs (option d). These are antiviral drugs that mimic nucleosides and interfere with viral RNA replication, making them a common treatment strategy for RNA viruses.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Enveloped RNA Virus Characteristics
Enveloped RNA viruses have a lipid membrane surrounding their RNA genome, which influences how they enter host cells and evade the immune system. Understanding their structure helps in targeting treatments that disrupt viral entry or replication.

Antiviral Agents and Their Mechanisms
Antiviral agents like nucleoside analogs mimic viral nucleotides, interfering with viral RNA replication. Injectable antibodies can provide passive immunity by neutralizing the virus, while interferons boost the host immune response to inhibit viral replication.

Limitations of Antibiotics in Viral Infections
Antibiotics target bacterial structures and processes, making them ineffective against viruses. Using antibiotics for viral infections does not treat the virus and can contribute to antibiotic resistance.
