Abstract

fetched live from OpenAlex

During the course of evolution, the avian egg has developed a wide variety of physical and chemical barriers to protect the embryo from invading pathogens. Avian reproduction, as well as food safety for the unfertilized table egg, is dependent on these barriers. Bacterial contamination is a major concern for unfertilized eggs that are meant for human consumption. The avian eggshell, and the associated cuticle and shell membranes, are the egg’s first line of defense against contamination. Although the eggshell is mainly calcium carbonate, it has an associated organic matrix for which transcriptomics and proteomics analyses have revealed proteins/genes that provide antimicrobial protection, or influence shell strength and cuticle quality. This chapter will review the barrier function of the eggshell and the proteins involved in defense of the egg to resist contamination. Further understanding of these proteins and genes will inform selection strategies to enhancement the egg’s innate antimicrobial activity as well as strengthen the physical barriers that prevent bacterial entry.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
