What is red leg syndrome, and what should make you call the vet at once?

Bacterial septicaemia caused by Aeromonas and similar organisms, triggered by environmental stress or poor water quality; it is a classic disease of amphibians. You will see reddening of the skin on the hind limbs and abdomen, 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 chytridiomycosis and what matters most in preventing it?

Fungal infection with Batrachochytrium dendrobatidis, a devastating disease for wild amphibian populations. You will see abnormal skin shedding, lethargy and abnormal posture. Prevention rests on quarantining new animals and avoiding mixing them with wild-caught animals. The treatment direction must be assessed by a veterinarian case by case; this text gives no drug names or doses.

What causes metabolic bone disease (MBD) and what matters most in preventing it?

Calcium deficiency and lack of vitamin D3 (UVB requirements vary by species). You will see softening of the bones and abnormal movement. Prevention rests on balanced calcium and vitamin supplementation. The treatment direction must be assessed by a veterinarian case by case; this text gives no drug names or doses.

Ten common diseases of the frog (White's tree frog／horned frog／clawed frog) gathered into one table: Red leg syndrome, Chytridiomycosis, Metabolic bone disease (MBD), Obesity and hepatic lipidosis, Chemical burn to the skin, Endoparasitism, Impaction, bacterial／fungal skin infection, Dehydration, and Trauma. 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.

Frog｜10 Common Diseases (cause → signs → examination → treatment direction → prevention)

This content is compiled from the disease table for the Frog (White's tree frog／horned frog／clawed frog) 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	Red leg syndrome	Bacterial septicaemia caused by Aeromonas and similar organisms, triggered by environmental stress／poor water quality; a classic disease of amphibians	Reddening of the skin on the hind limbs and abdomen, lethargy	Visual examination, bacterial culture	Antibiotics require a prescription; this is an emergency	Maintaining water quality, avoiding stress, quarantining new animals
2	Chytridiomycosis	Fungal infection with Batrachochytrium dendrobatidis, a devastating disease for wild amphibian populations	Abnormal skin shedding, lethargy, abnormal posture	PCR testing of a skin swab	Antifungal medication requires a prescription	Quarantining new animals, avoiding mixing with wild-caught animals
3	Metabolic bone disease (MBD)	Calcium deficiency, lack of vitamin D3 (UVB requirements vary by species)	Softening of the bones, abnormal movement	Palpation, X-ray	Calcium supplementation assessed by a veterinarian	Balanced calcium and vitamin supplementation
4	Obesity and hepatic lipidosis	Common in horned frogs; prolonged overfeeding	Marked obesity, reduced activity	Blood biochemistry	Dietary adjustment plus medication, which requires a prescription	Controlling feeding frequency and portion size
5	Chemical burn to the skin	Chlorine or detergent residue in contact with the skin	Ulcerated skin, abnormal secretions	Visual examination	Emergency management by a veterinarian	Dechlorinating the tank, avoiding detergent residue
6	Endoparasitism	Poor environmental hygiene, wild-caught animals	Weight loss, reduced activity	Faecal microscopy	Anthelmintics require a prescription	Quarantine, regular faecal examination
7	Impaction	Ingestion of substrate (horned frogs are at high risk because they swallow prey whole)	Refusal to feed, abdominal distension	Palpation, imaging	Severe cases require surgery	Avoiding substrate that is easily swallowed
8	Bacterial／fungal skin infection	Poor water quality, a damp and unhygienic environment	Skin lesions, abnormal secretions	Visual examination, culture	Prescription medication from a veterinarian	Maintaining water quality and environmental hygiene
9	Dehydration	Insufficient humidity (tree frogs／horned frogs) or poor water quality (clawed frogs)	Dry skin, reduced activity	Visual examination	Fluid replacement assessed by a veterinarian	Maintaining suitable humidity／water quality
10	Trauma	Jumping into the glass of the tank	Trauma with bleeding	Visual examination	Management by a veterinarian	Protecting the tank environment, reducing startling stimuli

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.

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.
