Colds and Respiratory Infections: Respiratory infections and colds are usually the direct result of improper care - drafts, cold bathing water, excessive temperature changes, and excessive humidity. Symptoms include nasal discharge, weeping eyes, coughing, wheezing, and sneezing. Most reptilien colds require treatment with antibiotics prescribed by your vet, because generally you won't notice the symptoms until the animal has become quite ill.
Mouth Rot (Stomatitis): Mouth rot is probably the worst bacterial infection in reptiles, and unfortunately is the cause of many an animal's loss. Bacteria of the groups Pseudomonas, Aeromonas, and Proteus accumulate in the oral mucous membrane and cause infections, swellings, and a cheesey discharge. Most cases of mouth rot occur after an initial injury to the snout and poor physical condition of the lizard. Early stages of mouth rot can be diagnosed if you notice the mucous membranes along the teeth and along the lips show a bright red inflammation. If you suspect your animal is infected, see your vet immediately. Proper diagnosis and treatment is best administered initially by your vet and can usually be continued at home.
Fungal Infections: Spread quickly and cause skin damage in reptiles that are generally kept in overly moist and warm enclosures. Infections usually start along the abdomen and produce raised brown-spotted scales. Further spreading causes open, weeping wounds in the skin. The fungus responsible for the infection must be diagnosed by your veterinarian who can then prescribe the proper treatment. Any lizard infected should be placed into quarrantine and kept there until the infection is stopped. Before placing the animal back into it's normal enclosure, the entire enclosure needs to be disinfected (including all decorations and contents) and treated with antifungals.
