What is bacterial septicaemia (the red-leg-like form), and what should make you call the vet at once?

Poor water quality and stress. You will see reddening of the skin and lethargy. The direction of management is antibiotics, which require a prescription, and this is an emergency. This row belongs to the group in the source chapter that needs prompt attention; the actual judgement still rests with a veterinarian case by case, and this text gives no drug names or doses.

What causes saprolegniasis and what matters most in preventing it?

Fungal infection triggered by poor water quality, common in axolotls. You will see cotton-wool-like white growth on the skin or gills. Prevention rests on regular water changes and maintaining water quality. The treatment direction must be assessed by a veterinarian case by case; this text gives no drug names or doses.

What causes impaction and what matters most in preventing it?

Ingestion of substrate, with axolotls at high risk. You will see refusal to feed and abdominal distension. Prevention rests on using fine sand or a bare tank bottom. The treatment direction must be assessed by a veterinarian case by case; this text gives no drug names or doses.

Ten common diseases of salamanders and newts (axolotl／Mexican axolotl／fire salamander／oriental newt) gathered into one table: Saprolegniasis, Impaction, Gill infection／atrophy, bacterial septicaemia (red-leg-like), Trauma (limb bites／impact injuries), Dehydration, Metabolic bone disease (MBD), Endoparasitism, Obesity, and Neoplasia. Each row lists cause, signs, examination, treatment direction and prevention; the treatment column gives categories only, never doses. It suits checking against when something looks wrong and you need to narrow down the direction first, or when taking on a new animal.

This content is compiled from the disease table for the Salamander/Newt (axolotl／Mexican axolotl／fire salamander／oriental newt) in the reptiles and amphibians chapter of the veterinary animal encyclopedia. The same sign calls for different handling in different species, and copying what is done for another species can be harmful — first confirm which animal you are dealing with.

#	Disease (Chinese／English)	Cause	Signs	Examination	Treatment direction	Prevention
1	Saprolegniasis	Fungal infection triggered by poor water quality; common in axolotls	Cotton-wool-like white growth on the skin／gills	Visual examination, microscopy	Prescription medication from a veterinarian, with water quality corrected first	Regular water changes, maintaining water quality
2	Impaction	Ingestion of substrate (axolotls are at high risk)	Refusal to feed, abdominal distension	Palpation, imaging	Severe cases require surgery	Using fine sand or a bare tank bottom
3	Gill infection／atrophy	Poor water quality (a risk particular to axolotls)	Darkening and shrinking of the external gills	Visual examination	Management by a veterinarian, with water quality corrected first	Maintaining water quality and a suitable water temperature
4	Bacterial septicaemia (red-leg-like)	Poor water quality, stress	Reddening of the skin, lethargy	Visual examination, bacterial culture	Antibiotics require a prescription; this is an emergency	Maintaining water quality, avoiding stress
5	Trauma (limb bites／impact injuries)	Animals housed together biting each other, problems with the structure of the environment	Loss of a limb or gill tissue with bleeding	Visual examination	Management by a veterinarian; axolotls can regenerate, but the wound still needs care	Avoiding housing aggressive animals together at high density
6	Dehydration	Insufficient environmental humidity for terrestrial species	Dry, cracked skin, reduced activity	Visual examination	Fluid replacement assessed by a veterinarian	Maintaining suitable humidity
7	Metabolic bone disease (MBD)	Calcium deficiency／lack of UVB in terrestrial species (the risk is lower in aquatic species)	Abnormal skeletal development	Palpation, X-ray	Calcium supplementation assessed by a veterinarian	Providing suitable UVB and calcium for terrestrial species
8	Endoparasitism	Poor environmental hygiene, wild-caught animals	Weight loss, reduced activity	Faecal microscopy	Anthelmintics require a prescription	Quarantine, regular faecal examination
9	Obesity	Overfeeding	A round body shape, reduced activity	Body condition assessment	Adjusting feeding frequency	Controlling the amount fed according to body size
10	Neoplasia	Older animals	Masses on the body surface, abnormal movement	Visual examination, imaging, biopsy	Treatment direction assessed by a veterinarian	Regular health checks for early detection

The 10 rows above are copied cell for cell from the encyclopedia chapter, neither rewritten nor condensed; the treatment column gives categories only, never drug names or doses, and any medication must be prescribed by a veterinarian. The line number and content hash of each row in the source chapter are in the evidence chain at the end.

Limits of this content

This content comes from the reptiles and amphibians chapter of the veterinary encyclopedia (see the evidence chain for the original location and content hash). The sources at the end are the authoritative materials cited by that chapter; the correspondence is at chapter level, which does not mean every sentence is traced sentence by sentence back to a given source. This material is for education and cannot replace diagnosis and prescription by a practising veterinarian; in an emergency, seek veterinary care immediately. This text has not been clinically reviewed by a named veterinarian.
