PROPOSITIONS associated with the PhD thesis Diversity in sporulation and spore properties
of foodborne Bacillus strains by Antonina O. Krawczyk
1. Knowledge on species and biological processes derived from studies
limited to laboratory-adapted strains and models shows just the tip of the iceberg. (Chapters 3-6, this thesis)
2. Mobile genetic elements are responsible for much more diversity
ob-served in nature than the commonly discussed antibiotic resistance mechanisms and virulence properties. (Chapters 4-5, this thesis) 3. The food production chain selects for bacterial strains with unusual
survival and resistance properties, making foodborne strains often comparable to isolates from extreme natural environments. (Chap-ters 3-6, this thesis)
4. Problems often come in pairs. / Nieszczęścia chodzą parami. (Polish proverb). (Chapters 4-6, this thesis)
5. Selecting the optimal reporter system is a crucial and non-trivial task in single-cell-level heterogeneity studies. (Chapters 2, this thesis) 6. Gene-trait matching is an effective approach for the identification of
novel genes involved in a biological process, when performed on a suf-ficient number of closely related bacterial strains. (Chapter 4, this thesis) 7. Strong inter-strain variation within a single bacterial species consti-tutes a common, but (too) often neglected phenomenon with signif-icant implications for medicine and industry. Therefore, inter-strain variation studies are necessary to describe the full phenotypic and genomic potential of the bacterial species. (Chapters 3-6, this thesis) 8. Closed genome sequences would make data analysis easier for
biolo-gists. (Chapters 3-6, this thesis)
9. Basic programming skills should be an integral part of the (life sciences) university study programs.
10. Although science promises objectivity and service to public interest, in re-ality it is often driven by subjective views, personal interests and politics. 11. Health care and health insurance systems are short-sighted and ma-nipulative, not only in regard to the patient wellbeing but also in re-gard to overall costs.
12. The ability to relax is a key element of a successful and productive work life.
