One of them is pathogenic ... that is, it produces disease... and the other one doesn't.
The answer is more or less contained in the question.
The reason one produces a disease and the other doesn't has to do with the precise details of each, and cannot be answered generally.
Some viruses are pathogenic in a particular species and harmless in others; other viruses affect entire classes of organisms (for example, pretty much all mammals can get rabies).
Pathogenic refers to something, typically a microorganism like a virus or bacteria, that is capable of causing disease or infection in a host.
pcDNA3 is a plasmid vector commonly used to generate high levels of transient protein expression in mammalian cells, while adeno-associated virus (AAV) is a small, non-pathogenic virus that is commonly used as a vector for gene therapy due to its ability to efficiently transduce a variety of cell types and its low immunogenicity. AAV is typically used for stable, long-term gene expression, while pcDNA3 is mainly used for transient expression.
The word "virus" originated from Latin, where it meant a slimy liquid or poison. Its modern meaning as a pathogenic agent was first used in the late 19th century by scientists studying infectious diseases.
A virus is a microscopic infectious agent that can cause diseases. A disease, on the other hand, refers to a particular condition or illness that affects the functioning of a living organism. So, a virus can be the cause of a disease, but not all diseases are caused by viruses.
A software virus attaches itself to a program or file and requires user action to spread, while a software worm can self-replicate and spread without user intervention. Viruses need a host file to infect, while worms can move across networks independently.
A pathogenic bacterium is alive while a virus is not.
Swine flu is caused by a virus. An allergy is caused by the body reacting to a harmless compound.
A Virus IS a type of Pathogen.
yep
A virus runs in a thread, as do all programs. The difference between a generic thread and a virus is that the thread may not be harmful, while the virus generally is.
Tobacco mosaic virus and wheat streak virus are harmless to humans.
The pathogenic organisms are not considered animals at all. The three pathogenic organisms are virus, bacterium, and fungus. All of these can potentially cause illness in animals and humans.
The difference between a common animal virus and a retrovirus is that a retrovirus only contains RNA while a common animal virus will have DNA or RNA.
Pathogenic refers to something, typically a microorganism like a virus or bacteria, that is capable of causing disease or infection in a host.
A pathogen = a virus. An organism, macro or micro, is alive, but viruses cannot technically be considered 'living.' Thus, non-pathogenic means 'not a virus'.
Mumps is caused by a virus, so it is a pathogenic disease.
Computer virus' attack switches whereas human virus' affect cells.
