Prevalence of Salmonella spp. in red-footed tortoises (Chelonoidis carbonaria) from Grenada, West Indies
Bibliographic record
Abstract
Background and Aim: There is currently no published information on the prevalence of Salmonella spp. in pet red-footed tortoises in Grenada. Monitoring is essential to understand the dynamics of the epidemiology of Salmonella. This study aimed to estimate the prevalence of Salmonella spp. from pet red-footed tortoises from Grenada and to test for antimicrobial drug resistance of the isolates. Materials and Methods: Established bacterial culture, serotyping, and antimicrobial susceptibility methods were used. Fecal samples were obtained from 114 tortoises from five parishes of Grenada, and cultured for Salmonella using enrichment and selective culture techniques. The serotyping of isolated Salmonella was performed at the Office International des Epizooties Salmonella Reference Laboratory, Guelph, Ontario, Canada. The isolates were tested for antimicrobial susceptibility in the Microbiology Laboratory of the School of Veterinary Medicine, St. George's University, Grenada. Results: Fifteen tortoises (13.2%) out of 114 were positive for Salmonella spp. Five serovars were identified: Salmonella Javiana (6.3%), Salmonella Rubislaw (6.3%), Salmonella Saintpaul (18.75%), Salmonella Glostrup (6.3%), and S. I: Rough.O;e,h:1,2 (62.5%). All isolates were sensitive to the 12 antimicrobial drugs. Conclusion: Three serovars (S. Javiana, S. Saintpaul, and S. Rubislaw) are known pathogens causing disease in humans. Since tortoises included in the study were pets, the tortoises may be a possible source of transmission of Salmonella to their owners. The tortoise owners should be educated on the importance of hygienic raising of their pets. This is the first report of isolation of Salmonella spp. from pet red-footed tortoises in Grenada.

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.
