What is the difference between Reservoir and paratenic hosts?

Reservoir host: The host of an infection in which the infectious agent multiplies and/or develops and on which the agent is dependent for survival in nature; essential host for maintenance of the infection when active transmission is not occurring.

Paratenic host: A host in which a parasite survives without undergoing any additional development (a transport host only) Source: Diagnostic medical parasitology, pg 1161

and

Any animal that harbors an infection that can be transmitted to humans is called a reservoir host, even if the animal is a normal host of the parasite. Source: Pg no:4

So, we can conclude that paratenic host is different from reservoir host due to following differences:

• Paratenic host don't harbour infective stages , if they harbour them, then they would be called as reservoir host but not paratenic host( see second definition)

• No development takes place in paratenic hosts, whereas in reservoir host development and multiplication takes place( see 1st definition).

Is a reservoir host a biological vector then?

I too asked the same question, its answer is here.
