What is American foulbrood American Foulbrood (AFB, Paenibacillus larvae), and what should send you to a veterinarian straight away?

Bacterial spores; the spores are extremely persistent in the environment, most jurisdictions list a confirmed colony as a notifiable disease, and destruction of the colony and equipment is often required to prevent spread. It presents with larval death and decay, sunken and perforated cell cappings, and a distinctive foul odour. The direction of handling is that it is dealt with under the regulations in most jurisdictions (suspected cases should be reported to the local beekeeping authority／quarantine service; it is not for the beekeeper to decide how to handle them). This row belongs to the category in the original chapter that needs prompt attention; the actual judgement still rests with a veterinarian assessing the individual case, and no drug names or dosages are given here.

What causes varroosis Varroosis (Varroa destructor), and what matters most in preventing it?

An external parasitic mite, the foremost threat to colony health worldwide, and a vector for several viruses. It presents with mites visible attached to larvae and adult bees, colony weakening, and worsening alongside viral disease. The key to prevention is regular monitoring and planned control, together with breeding queens selected for mite-resistant traits. The treatment direction must be assessed by a veterinarian case by case, and no drug names or dosages are given here.

What causes European foulbrood European Foulbrood (EFB, Melissococcus plutonius), and what matters most in preventing it?

Bacterial infection, milder than AFB but still contagious. It presents with larval death but a less pronounced odour, and signs milder than in AFB. The key to prevention is colony stress management (avoiding overcrowding and undernutrition) together with equipment hygiene. The treatment direction must be assessed by a veterinarian case by case, and no drug names or dosages are given here.

This record notes the source location and content hash of "Honeybees｜10 Common Diseases (cause → signs → examination → treatment direction → prevention)", so the text can be checked against the original.

How to use this record to verify

This record exists so that anyone can check for themselves whether the text has been altered. Every chapter of the veterinary encyclopaedia carries a starting line number and a content hash (the first 16 characters of its SHA-256). Recompute the hash over the original chapter: if it matches the value recorded below, what is published here is identical to the source chapter. The source list at the end is the authoritative material cited by that chapter — a chapter-level correspondence, meaning those sources underpin the chapter as a whole rather than mapping sentence by sentence. This is educational information and cannot replace a practising veterinarian; in an emergency, seek care immediately.

This record notes the source location of "Honeybees｜10 Common Diseases (cause → signs → examination → treatment direction → prevention) | Evidence chain": the section beginning at line 356 of `27-T8-農場與T9-馬.md` in the veterinary encyclopaedia. The SHA-256 of that section (first 16 characters) is `c2464b4400572581`, which anyone can recompute to confirm the content has not been altered.

Row-level anchors

Every row of the disease table carries a row-level anchor in the source chapter (claim id plus a SHA-256 of the row content); the anchor file is `planning-out/anchor-436.tsv`. Of the 10 rows in this section, 10 have a row-level anchor. One source row may map to several claim ids, listed separated by ／:
