During conjugation in ciliates, two cells attach, and their diploid micronuclei undergo meiosis to produce eight haploid nuclei per cell. All but one haploid micronucleus and the macronucleus disintegrate, and the remaining haploid micronucleus undergoes mitosis. The cells then exchange one micronucleus, which fuses with the partner's remaining micronucleus to form a new, genetically distinct diploid micronucleus. This new micronucleus divides mitotically twice to yield four micronuclei, two of which merge to form a new polyploid macronucleus before the genetically altered cells separate.

Ciliate Conjugation

Protist conjugation is a form of sexual reproduction in eukaryotes (specifically ciliates) where two cells of distinct mating types join to exchange genetic material, a process distinct from bacterial conjugation.

Microbiology covers the scope and sequence requirements for a single-semester microbiology course for non-majors. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of the text make the material interesting and accessible while maintaining the career-application focus and scientific rigor inherent in the subject matter. Microbiology’s art program enhances students’ understanding of concepts through clear and effective illustrations, diagrams, and photographs.

Microbiology is produced through a collaborative publishing agreement between OpenStax and the American Society for Microbiology Press. The book aligns with the curriculum guidelines of the American Society for Microbiology.
