Prevalence and Genotype Distribution of <i>Chlamydia psittaci</i> in Feral Canada Geese ( <i>Branta canadensis</i> ) in Belgium
Bibliographic record
Abstract
Chlamydia psittaci is a zoonotic pathogen with a wide range of avian hosts and worldwide geographical spread. Zoonotic transfer occurs by inhalation or direct contact and may cause psittacosis or parrot disease. Host reservoirs of particular epidemiological interest include gregarious or migratory species, as colonial behavior facilitates microbial spread amongst conspecifics and a migratory ecology permits disperse over a wide geographic region. The current study detected C. psittaci antibodies in 76 of 81 (93.8%) feral Canada geese (Branta canadensis) using a species-specific enzyme-linked immunosorbent assay. Viable C. psittaci were isolated from pharyngeal swabs of 47 of 81 (58%) birds, and subsequent ompA-based genotyping revealed genotypes E, B, and E/B. Absence of clinical symptoms in these geese could reflect a strong natural protection or a persistent infection. Canada geese are considered an important alien species in Europe. Current results denote that this avian reservoir poses a considerable risk to native wildlife as a potential source of C. psittaci.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
