Chapter 25, Problem 6
Negri bodies are associated with which of the following?
a. Marburg virus
b. Hantavirus
c. Coltivirus
d. Rabies virus
Verified step by step guidance1
Step 1: Understand what Negri bodies are. Negri bodies are cytoplasmic inclusion bodies found in certain infected cells, specifically neurons, and are considered pathognomonic for a particular viral infection.
Step 2: Recall the viruses listed in the options and their characteristics: Marburg virus causes hemorrhagic fever, Hantavirus is associated with pulmonary syndrome, Coltivirus causes Colorado tick fever, and Rabies virus causes rabies with neurological symptoms.
Step 3: Identify which virus is known to produce Negri bodies. Negri bodies are characteristic of the Rabies virus infection and are used as a diagnostic marker in brain tissue samples.
Step 4: Confirm that Negri bodies are not associated with Marburg virus, Hantavirus, or Coltivirus, as these viruses do not produce such inclusion bodies.
Step 5: Conclude that the correct association of Negri bodies is with the Rabies virus.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Negri Bodies
Negri bodies are distinctive cytoplasmic inclusion bodies found in nerve cells infected by the rabies virus. They serve as a diagnostic hallmark in histopathology for rabies infection, appearing as eosinophilic, round or oval structures within neurons.

Rabies Virus
Rabies virus is a neurotropic virus from the Lyssavirus genus that causes fatal encephalitis in mammals. It travels through peripheral nerves to the central nervous system, where it induces characteristic pathological changes including the formation of Negri bodies.

Viral Inclusion Bodies
Viral inclusion bodies are aggregates of viral particles or altered host cell components visible under a microscope during infection. They help identify specific viral infections, as different viruses produce unique inclusion bodies in infected cells.

Textbook Question
Polio and smallpox have been eliminated as natural threats to human health in the United States. (Some risk from bioterrorism remains.) You have considered the features of these diseases that allowed them to be eliminated. From your studies of other viruses, what other viral diseases are candidates for elimination? Why hasn’t AIDS been eliminated?
