The role of Cladophora glomerata as a habitat for bacterial communities and a reservoir of antibiotic resistance.
Bibliographic record
Abstract
This thesis studied the filamentous alga Cladophora glomerata???s role in providing a refuge for antibiotic resistance and analyzed the community composition of the bacterial colonizers of C. glomerata mats by taking samples of water and C. glomerata mats from 4 sites along nearshore Lake Ontario and 2 wetland sites. Using plate screening techniques, bacteria resistant to ampicillin were found at all sites and sampling dates and vancomycin resistant bacteria were found particularly in sites immediately downstream of a wastewater treatment plant. qPCR targeting antibiotic resistance genes demonstrate the presence of the resistance genes ampC, tetA, tetB, and vanA. Lab experiments showed that C. glomerata exudates promote the growth of E. coli. Illumina sequencing of the bacterial community indicated that C. glomerata harbours a bacterial community distinct from the surrounding water, and supports the growth of fecal bacteria and bacterial taxa including the genera Clostridium and Campylobacter.

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.
