Abstract
Due to the high demand for honey, beekeepers often feed the bees with antibiotics to protect honeybees against illnesses; the determination of veterinary drugs and their residues in bee products especially in honey is gaining importance. In this study, commercially available 15 different brands, a total of 22 honey (14 blossoms and 8 pines) samples obtained from 5 chain supermarkets in the city of Bingöl and Diyarbakır, Turkey were analysed for 29 antibiotic residues. These antibiotics belong to 10 different categories, including tetracyclines, aminoglycosides, macrolides, sulfonamides, fluoroquinolones, benzimidazoles, anthelmintic, amphenicols, quinolines, and oxazolidines. For the qualitative and quantitative determination of the antibiotics, a triple quadrupole liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used. A total of 10 out of 22 honey (8 blossom, 57.14 % and 2 pine, 25 %) samples were found to be positive for antibiotics. Among the tested antibiotics, tetracycline, dihydrostreptomycin, streptomycin, erythromycin, and sulfadimidine were detected in the honey samples. Dihydrostreptomycin and sulfadimidine were detected in 6 samples, erythromycin was determined in 4 samples, streptomycin was found in 2 samples, and lastly, tetracycline was detected only in one sample. The highest and the lowest concentrations of antibiotics detected in the samples were dihydrostreptomycin and erythromycin found at the amount of 992.58 μg/kg and 0.77 μg/kg respectively. The proposed method was validated with a limit of quantification (LOQ) and limit of detection (LOD) ranging between 0.42 and 3.22 μg /kg and 0.13-0.97 μg /kg respectively. Good linearities were also achieved ranging between R2 =0.987 and 0.999.

Abstract
The purpose of this research was to evaluate the persistence of penicillin G and dihydrostreptomycin in milk of lactating buffaloes following intramuscular injection of procaine penicillin G (200000 IU/mL) and dihydrostreptomycin sulfate (250 mg/mL) every 24 h for 3 days. Milk samples were collected twice daily up to the 13th milking post-treatment and analyzed by ultra-high-performance liquid chromatography coupled to tandem mass spectrometry. The analytical method has been validated according to Commission Decision 2002/657/EC. The highest concentrations of penicillin G (275 μg kg-1) and dihydrostreptomycin (220.5 μg kg-1) were detected in the milk of the first milkings post-treatment, and levels were below the maximum residue limit of 4 and 200 μg kg-1 in all treated buffaloes at milkings 12 and 2, respectively. The results of this study demonstrate that a nine-milking withdrawal time set for bovine milk was not adequate for depletion of penicillin G in lactating buffaloes.

Abstract
OBJECTIVE To develop a method for simultaneous determination of streptomycin and dihydrostreptomycin residues in tomato ketchup by ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). METHODS The sample was dissolved with phosphorus solution (pH 2) and extracted by ultrasonic. The pigment was removed with n-hexane. Then, the sample was cleaned up by HLB SPE. The HILIC chromatographic column (100 mm x 2.1 mm, 1.7 μm) was used to complete the separation under gradient elution. The mixed solution of 0.1% formic acid solution and acetonitrile was used as mobile phase. The detection of streptomycin and dihydrostreptomycin were carried out by MS/MS under multiple reaction monitoring (MRM) mode. The external standard method was used for quantitative analysis. RESULTS The calibration curves for streptomycin and dihydrostreptomycin were indicated in the range of 0.005 - 0.100 mg/kg, and the detection limits were both 0.005 mg/kg. The recoveries of streptomycin and dihydrostreptomycin were ranged from 79.5% to 93.9% with relative standard deviations no more than 10%. CONCLUSION The method is simple and accurate to meet the requirements for determination of streptomycin and dihydrostreptomycin residues in tomato ketchup.

Abstract
Impurities in streptomycin (STR) and dihydrostreptomycin (DHS) were investigated by hydrophilic interaction chromatography/electrospray ionization quadrupole ion trap/time-of-flight mass spectrometry (HILIC/ESI-QIT/TOFMS). Samples were separated on a fused-core silica column (100 mmx2.1 mm i.d., particle size: 2.7 microm) with isocratic elution using 200 mM ammonium formate buffer (pH 4.5) and acetonitrile as mobile phase. Constant neutral loss survey in accurate mass measurement was carried out by QIT/TOFMS. Formulae, chemical structures of impurities in an STR sample were suggested with supporting results on the probable pathways of STR biosynthesis by Streptomyces griseus.

Abstract
A liquid chromatographic/tandem mass spectrometric (LC/MS/MS) method was developed for determining dihydrostreptomycin, gentamicin C1, and neomycin in veal kidney, liver, and muscle. The extraction prior to injection on the automated cleanup/analysis system is very simple, permitting preparation of 24 veal samples for analysis in half a day of work. The extracts are purified online on a reversed-phase column, with the help of an ion-pairing agent, and the analytes are separated on a Nucleosil C18 column prior to analyses by electrospray MS/MS. The cleanup is sufficient to minimize ion suppression/enhancement phenomena and permits quantification of the analytes extracted from veal tissues. Four secondary ions were measured for every analyte, which gives unambiguous identification of the compounds under analysis. Calibration curves were linear for all analytes between 50 and 5000 ppb, and recoveries in kidney were 76, 57, and 51%, respectively, for dihydrostreptomycin, gentamicin C1, and neomycin. Estimated limits of detection for kidney were, respectively, 0.1, 0.1, and 0.4 ppb. When compared to an LC method with fluorescence detection, the method gave equivalent results for kidneys incurred with neomycin. This rugged method has been applied to the analysis of more than 1000 veal samples over a 1-year period.

Abstract
Dihydrostreptomycin (DHS) is an aminoglycoside antibiotic used in veterinary medicine in combination with benzylpenicillin for the treatment of bacterial infections in cattle, pigs and sheep. A method to determine its residues in edible tissues of cattle, as well as in milk, was developed and validated. Extraction of DHS from the tissues was performed using a liquid extraction with a 10 mM phosphate buffer containing 2% (w/v) trichloroacetic acid, while milk samples were treated with a 50% (w/v) trichloroacetic acid solution, followed by a solid-phase clean-up procedure on a carboxypropyl (CBA) weak cation exchange column. Ion-pair chromatography, using a mixture of 20 mM pentafluoropropionic acid in water and acetonitrile as the mobile phase, was used to retain DHS and the internal standard streptomycin (STR) on a Nucleosil (5 microm) reversed-phase C18 column. The components were detected and quantified by electrospray ionization (ESI) tandem mass spectrometry. The method could be validated according to EC (European Community) requirements with respect to linearity, trueness and precision, the latter evaluated at the maximum residue limit (MRL) - 1000 ng g(-1) for kidney, 500 ng g(-1) for muscle, liver and fat, and 200 ng g(-1) for milk -, at one-half of the MRL and at one and a half times the MRL. A limit of quantification of 10 ng g(-1) and 1 ng ml(-1) was obtained for all tissues and for milk, respectively, which is far below one-half of the MRL as requested, while the limit of detection was in the low ppb range, varying between 1.9 and 4.2 ng g(-1) for the different tissues tested, and being 0.6 ng ml(-1) for milk. The method was used for the monitoring of DHS residues in incurred tissue and milk samples coming from cattle medicated with DHS in combination with benzylpenicillin by intramuscular injection, in order to evaluate withdrawal times.

Abstract
A novel method for the non-derivatization liquid chromatographic determination of streptomycin (STR) and dihydrostreptomycin (DHSTR) was developed and validated based on evaporative light scattering detection (ELSD). Utilizing a ThermoHypersil BetaBasic C18 analytical column, evaporation temperature of 50 degrees C and pressure of nebulizing gas (nitrogen) of 3.5 bar, the optimized mobile phase was 1.25 mL L(-1) TFA aqueous solution, in an isocratic mode at a rate of 1.0 mL min(-1). STR was eluted at 5.6 min and DHSTR at 7.8 min with a resolution of 4.4. Linear calibration curves were obtained from 2 to 120 microg mL(-1) (r > 0.9990) for STR and 2-75 microg mL(-1) (r > 0.9994) for DHSTR, with a LOD equal to 0.7 and 0.5 microg mL(-1), respectively. The developed method was applied for the assay of STR and DHSTR (sulfate) in pharmaceutical raw materials and formulations, while the simultaneous direct determination of sulfate was feasible (tR = 2.5 min, LOD = 1.4 microg mL(-1), double logarithmic calibration curve in the range of 4-50 microg mL(-1), r > 0.9998). Modified isocratic mobile phase (H2O-ACN, 90:10, v/v, containing 1.25 mL L(-1) TFA), was used for the determination of streptomycin B impurity in STR sulfate raw material and a gradient mobile phase (H2O-ACN containing TFA) was used for the determination of DHSTR in the presence of penicillinG procaine. The developed method was also applied for the assay of commercial formulations (STR powder and DHSTR injection solution and suspension) (%recovery 98-102, %RSD < 1.3, n = 3 x 3), for the determination of STR in bacteria culture medium (%recovery 99.6, %RSD = 0.8, n = 3 x 3), and for the determination of DHSTR in human plasma (2.0-23.0 microg mL(-1)) after solid phase extraction using carboxylate cartridges (%recovery 98.4-101.8, %RSD = 3.2, n = 3 x 3).

Abstract
Two liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods were developed for the determination of streptomycin (STR) and its derivative dihydrostreptomycin (DHSTR) in milk and honey. These aminoglycoside antibiotics are used as veterinary drugs. In the EU, the presence of dihydro- and streptomycin residues in honey is forbidden, the maximum residue level (MRL) in milk is 200 microg/kg. The methods were optimised with regard to sensitivity and chromatographic efficiency, and validated by a procedure consistent with EU directive 2002/657. Average recoveries and accompanying standard deviations were satisfactory. The limit of quantification of STR was 2 microg/kg in honey and 10 microg/kg in milk, of DHSTR it was a factor two lower. The precision of the milk analysis was improved by using STR as the internal standard for DHSTR and vice versa. In a survey of 186 honeys available on the Dutch market, 26% of the honeys of foreign origin were positive for (DH)STR. This occurence rate was consistent with previous surveys, but lower concentrations were found.

Abstract
A sensitive and selective method using liquid chromatography-electrospray mass spectrometry (LC-ESI-MS) for the determination of aminoglycoside antibiotics, streptomycin and dihydrostreptomycin, in meat has been developed. The LC separation was performed on a TSK-gel Super ODS column (10 cm x 2 mm i.d.) using 5 mmol/L heptafluoro-n-butyric acid (HFBA)-acetonitrile (88:12) as the mobile phase at a flow rate of 0.18 mL/min. The positive ionization produced typical [M + H]+ molecular ions of both drugs (streptomycin m/z 582; dihydrostreptomycin m/z 584). The calibration graphs for streptomycin and dihydrostreptomycin were rectilinear from 0.25 to 25 ng with selected ion monitoring (SIM). The drugs were extracted with 1% metaphosphoric acid, and the extracts were added to 2 mL of 0.1 mol/L heptanesulfonic acid. The solution was cleaned up on a Bond Elut C18 (500 mg) cartridge. The recoveries of streptomycin and dihydrostreptomycin from swine and bovine muscle fortified at 0.2 microgram/g were 73.2-82.6%, and the detection limits were 0.01 microgram/g for both drugs.

Abstract
The analysis of dihydrostreptomycin sulfate using a column packed with base deactivated reversed phase silica gel and ultraviolet detection at 205 nm is described. The mobile phase consists of an aqueous solution containing 4 g/l of sodium sulfate, 1.5 g/l of sodium octanesulfonate, 100 ml/l of acetonitrile and 50 ml/l of a 0.2-M phosphate buffer at pH 3.0. The method allows separation of streptidine, dihydrostreptomycin B, streptomycin, dihydrostreptomycin and deoxydihydrostreptomycin, as well as some other components which were not identified. The total time of analysis is 55 min. The effects of the different chromatographic parameters on the separation were also investigated. A number of commercial samples were analyzed using this method.

Abstract
An LC method for the determination of the aminoglycosides streptomycin (STR) and dihydrostreptomycin (DHS) in milk was developed/modified on the basis of published papers. Mean recoveries were 87 and 95% for STR and DHS, respectively. Recoveries are dependent on the concentration level and batch of solid-phase extraction columns used, and independent of fat content and homogenization. The relative standard deviations are 15.6 and 9.6% for STR and DHS, respectively, at a level of 100 micrograms kg-1. Limits of detection (8 and 12 micrograms kg-1, respectively) and quantification (12 and 18 micrograms kg-1, respectively) are far below the EU maximum residue limit of 200 micrograms kg-1. Lyophilized DHS samples can be used for internal control of the analysis as the DHS concentration is not influenced by the lyophilization process and subsequent storage at 6 degrees C. In incurred milk samples no false negative results of preliminary confirmation tests (Charm II Aminoglycoside test, Ridascreen Streptomycin ELISA) with respect to DHS concentrations > or = 20 micrograms kg-1 as determined by the LC method are observed. DHS concentrations of incurred samples determined by ELISA are higher than those obtained by the LC method. These differences were more pronounced with incurred than with spiked milk samples, thus leading to the conclusion that in incurred samples substances are present which co-react in the ELISA and which are not detected by the LC method.

Abstract
A method is presented for the determination of dihydrostreptomycin in milk, muscle and kidney by reversed-phase ion-pair high-performance liquid chromatography and post-column derivatisation with beta-naphthoquinone-4-sulfonate prior to fluorescence detection. The new sample work-up procedures include acid precipitation of proteins and, in the case of muscle and kidney, removal of fats by solvent extraction followed by solid phase extraction on a cation exchanger. The fluorescence response was linear from 25 to 2000 micrograms l-1 of injected analyte. The detection limits were 10 micrograms kg-1 for milk and 15 micrograms kg-1 for muscle and kidney and the analyte recoveries were on average 93% for milk, 70% for kidney and 75% for muscle.

Abstract
The ratio-spectra zero-crossing first- and third-derivative spectrophotometry have been used for determining ternary mixtures of penicillin-G sodium, penicillin-G procain and dihydrostreptomycin sulphate salts. The procedures are accurate, nondestructive and do not require resolutions of equations. In both methods, calibration graphs are linear, with zero-intercept, up to 30 micrograms ml-1 of penicillin-G sodium and penicillin-G procain, and up to 42 micrograms ml-1 of dihydrostreptomycin sulphate. r = 0.9999 in each instance. Working wavelengths, 218.5, 211 and 236 nm, respectively, in the first-derivative mode, and 222.5, 311.5 and 242 nm in the third-derivative mode. Detection limits for each drug at p = 0.01 level of significance were calculated to be 0.058, 0.010 and 0.014 micrograms ml-1 and 0.14, 0.012 and 0.34 micrograms ml-1, in the first- and third-derivative methods, respectively. Both methods apply favorably to either laboratory mixtures or commercial injections.

A method developed for the determination of the aminoglycoside antibiotics streptomycin and dihydrostreptomycin in tissues was applied to the analysis of fluid milk. Samples are extracted with 3.6% perchloric acid, and then injected onto a trace enrichment column, from which they are eluted onto a reversed-phase analytical column. The analytes are detected by fluorescence following postcolumn derivatization with 1,2-naphthoquinone-4-sulfonic acid. Recovery of analytes was in the range of 50-65% for skim or partially defatted fluid milk, while recoveries for homogenized whole milk were lower. Limits of quantitation were 10 ppb for streptomycin and 20 ppb for dihydrostreptomycin.

Abstract
A method for the determination of streptomycin and dihydrostreptomycin in pork and bovine muscle and kidney was developed. Dilute perchloric acid solution is used to precipitate proteins and extract the analytes from the tissue. The extract is loaded onto a cation-exchange, solid-phase extraction column, and the drugs are eluted with pH 8 phosphate buffer. The eluant is chromatographed by using an on-line column enrichment liquid chromatographic system with postcolumn derivatization using 1,2-naphthoquinone-4-sulfonic acid and detection by fluorescence. The recoveries were 61.1% (coefficient of variation [CV], 7.3%) for streptomycin and 55.3% (CV, 8.2%) for dihydrostreptomycin. The detection limits were 10 ppb for streptomycin and 20 ppb for dihydrostreptomycin.

Abstract
Causes of the occurrence of pyrogenic impurities in injection and infusion preparations as well as false-positive and false-negative results possible in the pyrogen test are reported. Possibilities of excluding pyrogenic impurities in the preparations concerned and of avoiding false-positive and false-negative results in the pyrogen test are discussed.

Abstract
1. The transfer of aminoglycoside antibiotics into eggs was determined separately from albumen, yolk or whole egg after oral administration of dihydrostreptomycin (DHS), neomycin and spectinomycin and after an intramuscular injection of DHS. Residues were assayed by an agar plate diffusion method in cylinders with a specific test organism for each antibiotic. 2. Only DHS, administered by the intramuscular route, led to detectable residues in eggs. The total amount of DHS excreted via the eggs represented 1% of the dose administered. 3. Residues in the whole egg were detected for 8 d.

Abstract
The effect of the conditions of the formation of liposomal preparations of streptomycin and dihydrostreptomycin on incorporation of the antibiotics into the liposomes was studied. The liposomes were obtained with the detergent (cholate) method modified by the authors. The modification implies preliminary application of a 20 per cent antibiotic buffer solution on columns for gel filtration of a mixed mycellar antibiotic solution (20 per cent). The volume ratio of the preliminary applied buffer solution and the mixed mycellar solution is higher than 4:1. The new procedure is simple, readily reproduced, providing formation of the liposomal preparations characterized by high levels of the antibiotic incorporation (about 300 micrograms per 1 mg of lecithin). The preparations are stable with regard to the antibiotic release. The liposomes do not aggregate on storage for a long period (more than 6 months). The liposomal preparations thus formed may be useful as intravenous dosage forms of the antibiotics.

Abstract
Cows were given liquid intrauterine infusions of dihydrostreptomycin and penicillin or dihydrostreptomycin alone approximately 24 hours after the onset of oestrus to determine the necessary withholding period for milk intended for human consumption. When dihydrostreptomycin and procaine penicillin were administered together, a withholding period of 72 hours provided an adequate safety margin. Thirty-six hours was an adequate withholding period when dihydrostreptomycin was administered.

Abstract
Nonvolatile and thermolabile antibiotics are investigated both by field desorption and by secondary ion mass spectrometry (SIMS). It has been successfully demonstrated that these two methods are complementary in obtaining informations about molecular weight and structure. Although FD is most widely used for the investigation of nonvolatile biologically active compounds, there are some compounds of which FD can not provide reliable information. SIMS is successfully applied to obtain structural information of these compounds. SIMS spectra frequently depend on the surface conditions of sample holder materials.

Abstract
Because dihydrostreptomycin can remain as a slowly removed antibiotic residue in dairy animals and because of the need for more sensitive procedures with which to provide information concerning antibiotic residues in food products, procedures were developed in more sensitive assays of dihydrostreptomycin in milk and some representative dairy products. The cleanup procedures that aided these improvements were (i) precipitation of milk proteins by acidification and (ii) centrifugation to extract cheeses and to remove physical barriers to diffusion in the cylinder plate assay. In addition, a thin, single seeded assay layer was used to maximize diffusion. Levels of dihydrostreptomycin as low as 0.06 microgram/ml in milk and 0.2 to 0.4 microgram/g in cheeses were measurable; these levels were some fourfold more sensitive than those presently recommended by the Food and Drug Administration.

Abstract
The spectra produced by the acid treatment and alkaline treatment of streptomycin and dihydrostreptomycin have been investigated to obtain suitable methods for their determination. Mixtures of the two antibiotics have been successfully determined in the UV region. Thus, using the orthogonal function method, dihydrostreptomycin has been determined after acid treatment whereas streptomycin has been determined after alkaline treatment followed by immediate neutralization.
