Viruses exhibit a wide host range, meaning they can infect a diverse array of organisms. Bacteriophages are a well-known class of viruses that specifically target and infect bacteria. Similarly, viruses capable of infecting fungi, known as mycoviruses, have been identified. Furthermore, plant viruses are common and cause numerous diseases in agricultural crops. Therefore, all three listed categories—bacteria, fungi, and plants—can be hosts for viral infections.
