Reptiles and amphibians are largely present in many environments, including domestic areas when they kept as pet animals. They often harbor zoonotic pathogens, which can pose a serious risk of infection for humans, mainly immunocompromised individuals, the elderly, children, pregnant women. Several studies have been carried out to verify role cold-blooded animals epidemiology some bacteria,

Pharmacokinetic characteristics of florfenicol in green sea turtles (Chelonia mydas) and hawksbill sea turtles (Eretmochelys imbricata) after intramuscular administration

Journal of Veterinary Pharmacology and Therapeutics, Journal Year: 2024, Volume and Issue: 47(4), P. 300 - 307

Published: March 22, 2024

Abstract The pharmacokinetics of florfenicol (FFC) in green sea and hawksbill turtles were evaluated following intramuscular (i.m.) administration at two different dosages 20 or 30 mg/kg body weight (b.w.). This study (longitudinal design) used 5 for the dosages. Blood samples collected assigned times up to 168 h. FFC plasma analyzed using validated high‐performance liquid chromatography equipped with diode array detection. pharmacokinetic analysis was performed a non‐compartment approach. concentrations increased dosage. elimination half‐life similar between treatment groups (range 19–25 h), as well protein binding 18.59%–20.65%).

Antibiotic Resistance of Bacteria Isolated from Clinical Samples and Organs of Rescued Loggerhead Sea Turtles (Caretta caretta) in Southern Italy

Animals, Journal Year: 2024, Volume and Issue: 14(14), P. 2103 - 2103

Published: July 18, 2024

Antimicrobial resistance affects all environments, endangering the health of numerous species, including wildlife. Increasing anthropic pressure promotes acquisition and dissemination antibiotic by wild animals. Sea turtles, being particularly exposed, are considered sentinels carriers potential zoonotic pathogens resistant strains. Therefore, this study examined profiles bacteria isolated from loggerhead sea turtles hospitalised in a rescue centre Southern Italy over 9-year period. Resistance to ceftazidime, doxycycline, enrofloxacin, flumequine, gentamicin, oxytetracycline sulfamethoxazole-trimethoprim was evaluated for 138 strains clinical samples or organs 60 Gram-negative families were most isolated:
