This is referred to as: spontaneous recovery
Spontaneous recovery is a theory of learning and memory which involves unexpected and recurrence of a conditioned response after a period of reduced response or delay. Spontaneous recovery is associated with classical conditioning and operant conditioning. Extinction will happen quickly after a spontaneous recovery, if the conditioned and unconditioned stimulus is not connected.

The first person to discover and accurately describe microbes was the amateur microscopist Antony van Leeuwenhoek (1632 - 1723) of Delft, Holland. He earned his living as a draper and haberdasher but spent much of his spare time constructing simple microscopes composed of double convex glass lenses held between two silver plates. </span>His microscopes could magnify 50 to 300 times and he may have illuminated his liquid specimens by placing them between two pieces of glass and shining light on them at a 45 degree angle to the specimen plane.
From<span> 1673, He sent detailed letters describing his discoveries to the Royal Society of London and it is clear from his descriptions that he saw both protozoa and bacteria.</span>
