Immunoglobulin Deficiency in Cavalier King Charles Spaniels with <i>Pneumocystis</i> Pneumonia
Bibliographic record
Abstract
Abstract Serum concentrations of immunoglobulin G (IgG), IgM, and IgA were measured in 9 Cavalier King Charles Spaniels with pneumonia caused by Pneumocystis sp that were examined at 4 veterinary surgeries in the United Kingdom (UK) between September 2001 and November 2002. Pneumocystis pneumonia was confirmed in all dogs by visualization of the organism in bronchoalveolar lavage fluid or a transthoracic lung aspirate. Two dogs had a history of demodicosis. Immunoglobulin concentrations also were measured in breed-and age-matched dogs sampled over the same period. IgG concentrations were significantly (P= .000) lower in the affected dogs (median 3.2 mg/mL) than in the control dogs (median 8.5 mg/mL). IgM concentrations were significantly (P= .002) higher in the affected dogs (median 1.95 mg/mL) than in the control dogs (median 1.12 mg/mL). One affected dog had no change in IgG concentration more than 3 months after resolution of infection or vaccination, but did have reduction in IgM concentration after resolution of infection and vaccination. Control dogs had low serum IgG and IgM concentrations, compared with the reference interval for all dogs. Lymphocyte count in blood was normal or high in 7 of 8 affected dogs. The results of this study suggest that there is a defect in immunity in Cavalier King Charles Spaniels that underlies the susceptibility of these dogs to pneumocystosis. Further studies are indicated to elucidate the mechanisms behind the defect, the prevalence within the breed, and the potential mode of inheritance of the problem.

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.
