While visiting another forum earlier in the month, the topic of mange was brought up regarding the disease in coyotes. Instead of cluttering up the earlier coyote thread here with my response, a fresh wound seemed to be the better route: Sarcoptic mange, often called scabies, is a debilitating skin disease caused by these guys - Sarcoptes mites: This is a highly magnified image of one under the microscope.
Because viruses, bacteria, and fungi cause many well-known diseases, it is common to confuse them, but they are as different as a mouse and an elephant. A look at the size, structure, reproduction, hosts, and diseases caused by each will shed some light on the important differences between these germs.nimals, plants, fungi, and bacteria are all subject to viral infection. But viruses tend to be somewhat particular about what type of cells they infect. Plant viruses are not equipped to infect animal cells, for example, though a certain plant virus could infect a number of related plants.
The difference between a bacterial infection and a viral infection can make the difference between a life threatening condition and a harmless one, so you might want to read on. Bacterial infections are caused by bacteria and viral infections are caused by viruses.
