An intrafamilial transmission of<i>Arthroderma benhamiae</i>in Canadian porcupines (<i>Erethizon dorsatum</i>) in a Japanese zoo
Bibliographic record
Abstract
An intra-familial transmission of Arthroderma benhamiae in Canadian porcupines (Erethizon dorsatum) housed in a Japanese zoo was studied. The family consisted of an adult couple and two offspring (a male and a female). The porcupettes, born in Japan, showed severe hair loss while the parent animals, imported from the USA. (male) and Canada (female), showed mild symptoms or were asymptomatic. Morphologically identical Tricophyton spp. isolates were recovered within seven days from quills of all animals on chloramphenicol-supplemented potato dextrose agar plates incubated at 37 degrees C. Two representative colonies from each animal were identified as Arthroderma benhamiae Americano-European race based on mating type (+) and the internal transcribed spacer (ITS) 1-5.5S-ITS 2 region of the rRNA gene sequences (AB236404-AB236408). The present cases constituted the second isolation of dermatophytes from porcupines. There were two different ITS types, i.e., the predominant one isolated from all animals and a secondary one recovered from only the mother porcupine. The sequences have never been recorded in Japan or in the GenBank database to the best of our knowledge. In addition, they were located at a cluster involving the type strain and mating strains of A. benhamiae Americano-European race and its F1 progeny. In contrast, 28 rodents (eight species) and three insectivora (1 species) exhibited in the petting zoo were negative for any dermatophytes as determined by culture.

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.
