Regarding the use of chloramphenical and amikacin, I have found several sources stating they are indicated for a myco flareup and the safe to use for rats with normal kidney function provided you make sure the rat's fluid intake is adequate.

Except from my below links:

CHLORAMPHENICOL PALMITATE


--------------------------------------------------------------------------------
CHLORAMPHENICOL SODIUM SUCCINATE 25 to 90mg/lb TID, PO

Must be obtained from compounding pharmacy

--------------------------------------------------------------------------------
15 to 25mg/lb BID, SQ or IM

.15cc to .25cc/lb for 7 to 14 days Bacteriostatic, broad-spectrum antibiotic that penetrates tissues other antibiotics cannot (e.g., central nervous system and eyes). Effective against mycoplasma. Should not be used in combination with Tylan, Erythromycin, or Zithromax. Use with caution. Oral form may be obtained from a compounding pharmacy. Mixed to order in any flavor you request. Expensive. Prescription needed.

AMIKACIN

BRAND: AMIGLYDE-V 5mg/lb BID or TID, SQ or IM

.10cc/lb for 7 to 14 days Bactericidal, broad-spectrum antibiotic. Good for respiratory infections. Can cause kidney damage, but it is not at all common, however, encourage the rat to drink plenty of liquids to be safe. Should be used for severe infections, or after other possible drugs have failed. Relatively expensive. Prescription needed.
