Basically, there are five different stages of infectious disease which include the incubation stage, the prodormal stage, the illness stage, the decline stage and the convalescence. Firstly, the incubation period is a period where there are no signs and symptoms detected while the virus is incubating.
In Paramecium caudatum, the stages of conjugation are as follows (see diagram at right): 1  Compatible mating strains meet and partly fuse. 2  The micronuclei undergo meiosis, producing four haploid micronuclei per cell. 3  Three of these micronuclei disintegrate. 4  The two cells exchange a micronucleus. 5  The cells then separate.
