Tettelin

Tettelin is a surname that appears in scientific literature, most prominently associated with a microbiologist who worked at The Institute for Genomic Research (TIGR) and later at related genomics institutions. The individual, cited as H. Tettelin, is noted for early work in bacterial genomics and for co-authored studies that helped establish the field’s approaches to genome sequencing and comparative genomics.

Key contributions include leading sequencing projects that produced the genome of Streptococcus pneumoniae TIGR4, one of the early complete bacterial genomes studied in detail, and participating in the development of pan-genome concepts. The pan-genome describes the full set of genes found across all strains of a species and has influenced how researchers study genetic diversity in microbial populations.

Because of these contributions, the surname Tettelin appears in many microbiology and genomics publications. The individual is associated with data resources and public genome databases that have underpinned numerous comparative genomics studies and facilitated subsequent work in pathogen genomics.
