Determination of the Prevalence of Chlamydia psittaci by PCR in Iranian Pigeons
Bibliographic record
Abstract
Many areas in Iran such as parks and gardens can be highly contaminated with pigeon feces. Chlamydia psittaci is a lethal bacterial that causes endemic avian chlamydiosis, epizootic outbreaks in mammals, and respiratory psittacosis in humans. Chlamydia psittaci strains in birds infect mucosal epithelial cells and macrophages of the respiratory tract. The aim of this study was to determination of prevalence of Chlamydia psittaci in feces of pigeons in Iran using PCR assay. DNA was extracted from 445 fecal samples of pigeons. The prevalence of this pathogen was 14.3% in region of this study. These results indicate that pigeon feces are a source of several zoonotic agents for humans, bird and animals. We suggested that continuous surveys can estimate, and thus help to minimize the risk of humans contracting diseases from pigeons. Keywords: Chlamydia psittaci, pigeon, PCR

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.
