Also Known As: '''''Red-leg Disease'''''
==Introduction==
'''Red-leg syndrome''' is a serious condition in '''amphibians''' that is caused by '''septicaemia'''. The most common causative organism is '''''[[Aeromonas hydrophila]]''''', but infection with other ''[[Aeromonas species|Aeromonas spp.]]'' and [[Gram Negative Bacteria - Overview|Gram-negative]] organisms such as ''[[Pseudomonas species - Overview|Pseudomonas]]'' and ''[[Proteus|Proteus spp.]]'' can also result in the disease. Infection normally occurs secondary to '''poor husbandry and sanitation''', or the feeding of '''contaminated foodstuffs'''.
==Clinical Signs==
The clinical signs associated with the [[Septicaemia and Enteritis, Bacterial|septicaemia]] are '''erythema''' and '''full-thickness ulceration''' of the skin - particularly on the '''limbs'''. Systemic signs such as anorexia and lethargy are seen prior to '''death'''. Mortality rates are high.
==Diagnosis==
The clinical signs are very suggestive of the condition, but '''specific microbiological culture''' is necessary to confirm diagnosis. A '''thioglycholate broth''' that is incubated at '''30°C''' at a '''reduced oxygen''' atmosphere is used to grow the bacterium.
==Treatment==
Any affected or in-contact frogs should be placed in '''isolation''', in tanks with a low stocking density. High levels of''' hygiene''' should be maintained until healing has occured.
There are two options for medical treatment:
* Administration of an effective '''[[Antibiotics|bacteriocidal antibiotic]]''' (based on culture and sensitivity) '''orally or intramuscularly''' to individual frogs.
* Administration of '''[[Fluoroquinolones|enrofloxacin]]''' to the '''tank water''' of the affected frogs.
==Control==
Husbandry measures such as '''strict quarantine, high hygiene standards and dietary control''' can prevent outbreaks.
==Prognosis==
As Gram-negative organisms are normally very virulent in amphibians, the prognosis is '''guarded to poor'''.
