Seven different dosage levels of chloramphenicol, dihydrostreptomycin
sulfate, neomycin, penicillin G, streptomycin sulfate, penicillin G + streptomycin sulfate and penicillin G + streptomycin sulfate + chloramphenicol were added to each culture of microalgae.
antibiotics (200 mg procain penicillin plus 250 mg dihydrostreptomycin
sulfate; Diperinisol, Bayer, Istanbul, Turkey) and analgesia with i.m.
(Tamura-seiyaku Corporation, Tokyo, Japan), at a concentration of 10 ppm, was added to the water used for cultivation to prevent bacterial attachment to the larvae.
 proposed an HPLC-MS method for the determination of STP and dihydrostreptomycin
in milk and honey.
The parameters for positive results of the tetracycline antibiotics tested are: oxytetracycline (10 [micro]g/kg), tetracycline (10 [micro]g/kg), chlortetracycline (10 [micro]g/kg), and doxycycline (20 [micro]g/kg); the parameters for positive results of the aminoglycoside antibiotics tested are: dihydrostreptomycin
(10 [micro]g/ kg), gentamicin (50 [micro]g/kg), hygromycin (20 [micro]g/kg), kanamycin (20 [micro]g/kg), neomycin (20 [micro]g/kg), paromomycin (25 [micro]g/kg), spectinomycin (50 [micro]g/kg), and streptomycin (20 pg/ kg).
This solution contained 70,000IU of procaine benzylpenicillin, 70mg of dihydrostreptomycin
sulfate, 1.2mg of piroxicam and 3.46mg of procaine hydrochloride per kg of body weight, in a single dose.
The analytical standards used for the tetracyclines (chlortetracycline, doxycycline, oxytetracycline, and tetracycline) and aminoglycosides (amikacin, apramycin, dihydrostreptomycin
, gentamicin, hygromycin, kanamycin, neomycin, spectinomycin, streptomycin, and tobramycin) families were purchased from Sigma Chemical Co.
Antibiotic treatment with Repen (Benzilpenicillina dihydrostreptomycin
) at a dosage of 20.000 IU of Benzil-penicillina and 12.5 mg of dihydrostreptomycin/kg for 5 days IM.
The antibiotics used are mainly tetracyclines (oxytetracycline, doxycycline, remacycline, and chlortetracycline), sulphadimidine, dihydrostreptomycin
, piperazine, albendazole, tylosin, ivermectin, and benzylpenicillin which can lead to possible cross- and co-resistance [42, 43].
Erythromycin (ERY), Penicillin G sodium (PG) Dihydrostreptomycin
sesquisulfate (DHS), Trimethoprim (TMP), Sulfadimerazine (SLF), Sodium chloride (NaCl), D-(+)-Glucose, Manganese sulfate (MnSO4), Ethanol, Sodium hydroxide (NaOH) and Acetic acid were purchased from Sigma Aldrich.
