determination of drug residues in food is of great importance due to their toxicity. long-term exposure with low level of drug residues could be important, especially in children. based on document study, oxytetracycline (otc) is a prophylaxis and treatment agent for great number of diseases and possesses a broad spectrum activity against many pathogenic organisms and can be toxic or cause alle...

objective(s):  oxytetracycline (otc) is a broad spectrum antibiotic widely used for treatment of a wide range of infections. however, its improper human and animal use leads to toxic effects, including hepatonephrotoxicity. our objective was to evaluate protective effects of nigella sativa oil (nso) and/or ascorbic acid (aa), against otc-induced hepatonephrotoxicity in rabbits. materials and me...

Oxytetracycline (OTC) has been used for years in medical field. It is a wide-spectrum antibiotic, belonging to the group of tetracyclines with bacteriostatic activity (1-4). OTC chemical name is 4-(dimethylamino)-1,4,4a,5,5a,6,11,12a-octahydro3,5,6,10,12,12a-hexahydroxy-6-methyl-1,11-dioxotetracene-2-carboxamide. OTC possesses broad antimicrobial spectrum, similar to tetracycline. The antibioti...

On 1,374 food-producing animal farms in 2001-2004, we investigated the influence of antimicrobial usage within 6 months before a survey conducted on antimicrobial resistance in Campylobacter. Tetracyclines and fluoroquinolones were used for therapeutic purposes on 107 and 21 farms, respectively. Oxytetracycline-resistant C. jejuni and C. coli were found in 57.1% (8/14) and 92.5% (37/40) of the ...

Size and age estimates at sexual maturity were determined for 162 male and 273 female little skates Leucoraja erinacea collected from the western Gulf of Maine. Maturity ogives suggest that 50% maturity in females occurs at age 9.5 years and 480 mm total length (LT), whereas 50% maturity in males occurs at a slightly younger age of 7.7 years and smaller size of 460 mm LT. Age estimates were mad...

Dosis diaplikasikan dengan dicampur pakan dosis 250 gram pakan/2 (oxytetracycline 200 mg, MgSO4.7H2O 25 C 50 20 gm). Sampel penelitian sebanyak 90 ekor terbagi men...

Mixtures of biological control agents can be superior to individual agents in suppressing plant disease, providing enhanced efficacy and reliability from field to field relative to single biocontrol strains. Nonetheless, the efficacy of combinations of Pseudomonas fluorescens A506, a commercial biological control agent for fire blight of pear, and Pantoea vagans strain C9-1 or Pantoea agglomera...
