[QUOTE=Herpvet;90952]Hi,

Just a couple of comments on this (sorry, I get picky sometimes when I see these types of articles).

"Red leg" is a bit of an ambiguous term given that it is used non-rigorously by many people, but in the veterinary sense the preferred term is technically dermatosepticaemia. It is pathogen-associated septicaemia (systemic infection) - typically bacterial but as noted viruses, Chlamydophila and fungi may also be causes. The visible reddening is caused by various degrees of erythema/petecchiation/ecchymoses - basically dilation/small ruptures/large ruptures of the skin blood vessels due (it is thought) to damage to blood and vessels from the pathogen and/or its toxins.

"Stress" is almost always considered to be a factor in this condition, as with most amphibian health problems

[QUOTE]""Aeromonas hydrophyla is actually a parasite"" [QUOTE]

Unless Aeromonas hydrophyla exists and isn't just a typo in the original paper....Aeromonas hydrophila is a bacterium. Parasite as a term is not generally applied to bacteria, viruses or fungi

[QUOTE] Red leg is a difficult topic. It is a syndrome - a collection of symptoms - not a specific disease. Most all available information on it is theoretical and differing theories and opinions result in much controversy on the issue.
To start, the name itself is confusing since redness in the legs has little or nothing to do with it. Several species of frogs have a red tint to their legs which is perfectly normal and certainly no indication of illness. The reddening which can occur with this condition is as a result of the rupturing of blood vessels which causes a collection of pooling blood under the skin. This is most evident and visible in the legs and belly due to the light color of the skin allowing the red color of the blood to show through the skin. So it's important to point out that red legs are not a clear indication of this condition.
Secondly, there is still some debate as to the specific pathogen that causes this condition. It is most commonly believed to be caused by Aeromonas. It is believed that the causing pathogen is an opportunistic bacteria which lies dormant in the frog's system waiting for a chance to overtake it. A healthy frog's immune system can effectively fight off the bacteria. Any stressing factor, such as: improper temperature and/or humidity regulations, unclean tank conditions, infrequent water changes resulting in dirty water, unnecessary handlings, mixing species, exposure to toxins, another illness, etc., can result in a weakened immune system. Once the immune system is weak and not functioning properly, it can no longer hold the bacteria at bay. The bacteria then multiples and overtakes the system resulting in infection and the frog having "red leg". Although several antibiotics and various other treatments have been tried, there is no known cure. Therefore, prevention of this condition is very important as preventing it from occurring is much easier than treating and/or curing it as few frogs survive the illness.[QUOTE]

Well - having just said it's a syndrome, this article then seems to try to suggest there is a specific pathogen rather than one of many that may be the cause in a particular case, although it makes mainly valid points.

[QUOTE]In amphibians bacterial infections are commonly caused by gram-negative bacteria, such as Aeromonas, Pseudomonas, Proteus, and E. coli. Poor husbandry, (e.g., overcrowding, poor water quality, inappropriate cage design or setup, spoiled food, exposure to toxins such as pesticides) may allow one of these bacteria to overwhelm amphibian's immunologic defenses.
Aeromonas is the most common cause of clinical bacterial diseases in amphibians and has been associated with the syndrome known as red leg disease. Once the first warning signs are noticed, (e.g., reddening of the under-skin, loss of appetite) appropriate antibacterial therapy is necessary. Treatment will depend on the exact pathogen that has been cultured and definitely identified. [QUOTE]

No argument with this (unless I really want to quibble - antimicrobial is better than antibacterial here as other microorganisms may be involved...sorry)

[QUOTE] The most infamous frog disease of captive frogs, Red-leg is usually caused by the parasite Aeromonas hydrophyla. It appears as a reddening of the skin, particularly on the belly and underside of the thighs, (not to be confused with the natural colorings of some species of frogs!) Frogs that get red-leg tend to act apathetic and lazy. This is a really lethal disease so isolate the affected frog(s) right away! Sometimes in the case of newly imported animals it is more likely due to abrasions caused by dry packing, like cardboard. In the latter case, the only treatment necessary is to correct the cause and keep the affected animal(s) in an incredibly clean cage for a few days. Otherwise, red leg caught in it's early stages can sometimes be treated by bathing the frog in a Sulfamethiazine bath (15 ml for every 10 l water) daily for 2 weeks, or a 2% solution of copper sulfate or potassium permanganate for the same period. If it shows no signs of getting better after the first week, sometimes you can treat them with the use of an antibiotic like tetracycline, so consult your veterinarian on treatment. [QUOTE]

Ignore these treatment suggestions. Get the frog to a vet if possible. More modern antibiotics are likely to be much more effective, and other supportive treatments such as anti-inflammatories may help as well.

[QUOTE]Treating “red-leg” syndrome will depend on the underlying cause of the disease. For example, if it is due to the Aeromonas hydrophila bacterium, your veterinarian will prescribe antibiotics for the amphibian. Follow the guidelines set by your veterinarian to get optimum results.[QUOTE]

True.

[QUOTE]Red-leg syndrome, refers to the hyperemia of the ventral skin that accompanies systemic infection in amphibians. Saprophytic, gram-negative bacteria such as Aeromonas spp, Pseudomonas spp, Proteus spp, and Citrobacter spp typically result in “red-leg syndrome”. Viruses, fungi, and other pathogens may cause similar lesions.

I don't like the word saprophytic - it refers to organisms that derive nutrition from dead/decaying matter, and implies that it is not an active pathogen, which these organisms definitely can be.

Hope this helps,

Bruce.
Hi Bruce,
Thanks so much for posting , it is truly appreciated. You don't have to apologize about being picky. I appreciated your responding to these quotes.

I posted these quotes ( it was simply information I set aside for myself over the past year or so) . It helps to remind me - that prevention is the best medicine. I'm afraid that my intention to help ( the FF with her Red Eye ) went off the beat in path. None of this was scientific research. I did not save any resource information to link to. Quotes were used in my post because I would never want to take credit for another person written material- right or wrong.
