Ceftazidime
Sensitive Bacterial Infections
Pharmacokinetic Data
Red-Eared Sliders (Trachemys scripta elegans): 20-40 mg/kg, SC, q5d (Hiebert et al., 2024).
Loggerhead sea turtles (Caretta caretta): 20 mg/kg, IV/IM, q3d (Stamper et al., 1999).
Freshwater Turtles (T. carolina carolina, Trachemys scripta scripta, Pseudemys concinna): 20 mg/kg, IM, q72h q5d (Cerreta et al., 2018).
Kemp’s ridley turtles (Lepidochelys kempii): 22 mg/kg, SC q3d (Innis et al., 2012)
Indication Data
Post Hibernation leucopaenia and septicaemia (Testudo sp): 20 mg/kg, SC/IV/IM, q3d ((McArthur et al., 2004)
Immunosuppression, Septicemia, and Other Infections (Marine Turtles): 22 mg/kg, SC/IV/IM, q3-5d (Innis et al., 2012)
Antibiotic Classification(s)
EMA: B (Restrict) (EMA, 2024)
WHO: Tier 2 (Abdelsalam Elshenawy et al., 2023; WHO, 2023)
ARAV: Tier 2 (Divers et al., 2017; Divers and Burgess, 2023)
BSAVA: Second Line (Hedley et al., 2021)b
AMR Considerations
Only to be used if culture and sensitivity or MIC testing indicate WHO/ARAV/AAHA Tier 1 drugs are ineffective.
Therapeutics
Administration Routes
Although the PK studies have included only IV and IM routes of administration (Stamper et al. 1999, Innis et al. 2012), SC administration is commonly employed in chelonians with apparently good effect (Innis et al., 2017)
Administration Sites
SC administration sites: The skin between the neck and forelimbs (Divers and Stahl, 2019).
IM administration sites: The forelimb and pectoral muscles (Divers and Stahl, 2019).
IV administration sites: The jugular, brachial, or ventral coccygeal veins (Divers and Stahl, 2019).
Adverse Effects Profile
Ceftazidime appears well tolerated in all chelonian species. No publications examined discuss adverse effects or resistance development in chelonans.
Patient Support
Hydration, thermal, and nutritional support should always be provided to critically ill cheloians.
