This study was conducted to determine whether the approved doses of oxytetracycline (OTC) for breeder hens and meat-type poultry would produce drug residue transfer into egg components when fed to laying hens. Twenty hens were assigned to equal groups (n = 10) and fed either 50 or 200 g/ton OTC for 5 d. Oxytetracycline concentrations in egg components were determined daily during a 2-d pretreat...
A total of 120 purebred Hereford cattle were selected from a herd on a ranch in Argentina that had a severe outbreak of infectious bovine keratoconjunctivitis (IBK, pinkeye) caused by Moraxella bovis. The animals were separated into six treatment groups: a nonmedicated control group, a group that received oxytetracycline at 300 mg injected intrapalpebrally, and four groups that received tilmico...
Normal prostate tissue contains high levels of citrate. In the presence of prostate cancer, the citrate level is diminished. In this paper we show that it is possible to use europium-oxytetracycline complex as a citrate fluorescent probe and consequently as a prostate cancer probe. We analyzed normal nude male mice urine and urine from nude male mice in which prostate cancer was induced by intr...
Panahi Z, Khakvar R, Aliasgharzad N, Zehtab S, Farshbaf PourAbad R (2023) The effect of copper nanoparticles on soft rot agent of potato, carrot and onion. Plant Pathology Science, 12(1):1-11. Doi: 10.2982/PPS.12.1.1 Abstract Introduction: Bacterial soft rot caused by Pectobacterium species is one of the important and common diseases in Potatoes and vegetables. Disinfection of tubers or...
to evaluate the effect of intrauterine cephapirin on treatment of endometritis 39 holstein dairy cows that affected with postpartum endometritis were selected and randomly assigned to two experimental designs. in experiment 1, 6 out of 14 cows were 25 to 30 days after parturition were treated by intrauterine oxytetracycline. another 8 cows were treated by intrauterine cephapirin (metri-care). i...
background: the antibiotics are excreted after their effect on the host body and together with other waste disposal are entered the treatment plant processes. antibiotics prevent the biological sewage treatment in the plant which consequently causes hazards to the environmental and human health. the purpose of this study was to investigate the effect of some popular antibiotics used by human an...
BACKGROUND Oxytetracycline (OTC) is a broad-spectrum antibiotic commercially produced by Streptomyces rimosus. Despite its importance, little is known about the regulation of OTC biosynthesis, which hampered any effort to improve OTC production via engineering regulatory genes. RESULTS A gene encoding a Streptomyces antibiotic regulatory protein (SARP) was discovered immediately adjacent to t...
Oxytetracycline is used to treat various disorders in poultry, particularly hens. Their use, however, may be connected with unsatisfactory residual levels food. Because the generally method for analyzing oxytetracycline residues expensive, unique preparation methods such as Molecularly Imprinted Polymer (MIP) approach have been developed. MIP one of most successful pre-analysis procedures extra...
Background: The aim of the present study was to investigate the effect of Paprika on the metabolism of lipid changes and hepatic enzyme activities following oxytetracycline administration in rats. Materials and Methods: A total of 36 adult male rats were divided into 6 equal groups and treated as follows. The control group (normal saline), fatty liver FL (oxytetracycline (Erfan drug Company) ...
