Abstract
The present study aimed to characterize the pharmacokinetic profile of oxytetracycline long-acting formulation (OTC-LA) in Thai swamp buffaloes, Bubalus bubalis, following single intramuscular administration at two dosages of 20 and 30 mg/kg body weight (b.w.). Blood samples were collected at assigned times up to 504 h. The plasma concentrations of OTC were measured by high-performance liquid chromatography (HPLC). The concentrations of OTC in the plasma were determined up to 264 h and 432 h after i.m. administration at doses of 20 and 30 mg/kg b.w., respectively. The Cmax values of OTC were 12.11 ± 1.87 μg/mL and 12.27 ± 1.92 μg/mL at doses of 20 and 30 mg/kg, respectively. The AUClast values increased in a dose-dependent fashion. The half-life values were 52.00 ± 14.26 h and 66.80 ± 10.91 h at doses of 20 and 30 mg/kg b.w, respectively. Based on the pharmacokinetic data and PK-PD index (T > MIC), i.m. administration of OTC at a dose of 30 mg/kg b.w once per week might be appropriate for the treatment of susceptible bacterial infection in Thai swamp buffaloes.

Abstract
To evaluate the fate and disposition of marbofloxacin (MBF) in freshwater crocodiles (Crocodylus siamensis), MBF was administered either intravenously (i.v.) or intramuscularly (i.m.) at a dosage of 2.0 mg/kg body weight. The concentrations of MBF in plasma were measured using high-performance liquid chromatography equipped with a fluorescence detector. The concentrations of MBF in the plasma were measurable up to 144 h after i.v. and i.m. administration. After the first 45 min, the mean pharmacokinetic profiles produced by the two administration routes were almost identical. No statistically significant differences in the pharmacokinetic parameters between the groups were observed. The half-life was long (about 2.5 days), the volume of distribution was large (about 1.44 L/kg), λz was small (0.01 h-1 ), and the clearance was slow (22.6 mL/h/kg). The absolute i.m. bioavailability (F%) was 105.36%. The dose of MBF administered in this study seems to produce appropriate PK-PD parameters that predict antibacterial success for disease caused by susceptible bacteria. More studies are warranted to evaluate the likely residues after administration of multiple doses.

Abstract
This study aimed to investigate the pharmacokinetic characteristics of amoxicillin (AMX) in Thai swamp buffaloes, Bubalus bubalis, following single intramuscular administration at two dosages of 10 and 20 mg/kg body weight (b.w.). Blood samples were collected at assigned times up to 48 h. The plasma concentrations of AMX were measured by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The concentrations of AMX in the plasma were determined up to 24 h after i.m. administration at both dosages. The Cmax values of AMX were 3.39 ± 0.18 μg/mL and 6.16 ± 0.18 μg/mL at doses of 10 and 20 mg/kg, respectively. The AUClast values increased in a dose-dependent fashion. The half-life values were 5.56 ± 0.40 h and 4.37 ± 0.23 h at doses of 10 and 20 mg/kg b.w, respectively. Based on the pharmacokinetic data and PK-PD index (T > MIC), i.m. administration of AMX at a dose of 20 mg/kg b.w might be appropriate for the treatment of susceptible Mannheimia haemolytica infection in Thai swamp buffaloes.

Abstract
Fates and residue depletion of enrofloxacin (ER) and its metabolite ciprofloxacin (CP) were examined in giant freshwater prawns, Macrobrachium rosenbergii, following either single oral (p.o.) administration of ER at a dosage of 10 mg/kg body weight (b.w.) or medicated-feed treatment at the feeding concentration of 5 g/kg of feed for five consecutive days. The concentrations of ER and CP in prawn muscle tissues were measured simultaneously using high-performance liquid chromatography (HPLC) equipped with a fluorescence detector. Muscle tissue concentrations of ER and CP were below the detection limit (LOD, 0.015 microg/g for ER; 0.025 microg/g for CP) after 360 and 42 h, following single p.o. administration respectively. Peak muscle concentration (C(max)) of ER was 1.98 +/- 0.22 microg/g whereas CP was measurable at concentrations close to the detection limit of the analytical method after p.o. administration at a single dosage of 10 mg/kg b.w. The concentration of ER in prawn muscle tissue with respect to time was analyzed with a non-compartmental pharmacokinetic model. The elimination half-life and area under the curve of ER were 39.33 +/- 7.27 h and 168.7 +/- 28.7 microg x h/g after p.o. administration at a single dose of 10 mg/kg x b.w. respectively. In medicated-feed treated group, ER was detectable in prawn muscle tissue 11 days postdosing at the dose of 5 g/kg of feed for five consecutive days, which is the value corresponding to the maximum residue limit (MRL) of ER in animal products. The maximum concentrations of ER and CP were 2.77 +/- 0.91 and 0.06 +/- 0.006 microg/g during medicated-feed treatment and postdosing respectively. The values of elimination half-life and absorption half-life of ER after single p.o. administration at a dosage of 10 mg/kg b.w. corresponded well with the values determined from medicated-feed treated group, showing 41.01 +/- 6.62 and 11.36 +/- 3.15 h respectively in M. rosenbergii. Based on data derived from this study, to avoid the ER residue in prawn muscle, it should take at least 11 days postcessation of medicated feed containing ER at the dose concentration of 5 g/kg of feed twice a day at a rate of 1% of total body weight for five consecutive days to wash out the drug from the muscle of M. rosenbergii.
