| − | Sample all suspected infections for microscopy, culture and sensitivity. The majority of bacterial infections in lizards are by Gram-negative organisms, particularly Enterobacteriacae. Therapy may be required before the results of bacterial sensitivity tests are known.

| − | *Aminoglycosides and quinolones are effective against most aerobic pathogens and there is little bacterial resistance to them.
| + | [[Lizard Formulary - Hormones|Hormones]] |
| − | *The fluoroquinolone derivative enrofloxacin is bacteriocidal (inhibit microbial DNA gyrase) and is well distributed to tissues. It is active against a wide range of Gram-negative organisms as well Gram-positives and Mycoplama spp. It is not effective against anaerobes.
| + | [[Lizard Formulary - Nutritional Support|Nutritional support]] |
| − | *Carbenicillin and ceftazidime are good broad-spectrum antibiotics useful against anaerobes as well as most Gram-negative pathogens. If Pseudomonas spp. and anaerobes are present, ceftazidime is the most appropriate choice.

| − | The following has also been advised: amikacin in combination with ampicillin for respiratory infections; chloramphenicol for gastrointestinal infections; an aminoglycoside in combination with a broad spectrum penicillin for general systemic infections.
