Borrelia burgdorferi lacking all cp32 prophage plasmids retains full infectivity in mice
Bibliographic record
Abstract
The causative agent of Lyme disease, Borrelia burgdorferi, contains a unique, segmented genome comprising multiple linear and circular plasmids. To date, the genomes of over 63 sequenced Lyme disease Borrelia carry one or more 32 kbp circular plasmids (cp32) or cp32-like elements. The cp32 plasmids are endogenous prophages and encode, among other elements, a family of surface exposed lipoproteins termed OspEF-related proteins. These lipoproteins are synthesized during mammalian infection and are considered important components of the spirochete's adaptive response to the vertebrate host. Here, we detail the construction and infectivity of the first described B. burgdorferi strain lacking all cp32 plasmids. Despite their universal presence, our findings indicate that B. burgdorferi does not require any cp32 plasmids to complete the experimental mouse-tick-mouse infectious cycle and a total lack of cp32s does not impair spirochete infectivity.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
