Background: Tetracycline antibiotics are widely used for prevention and control of disease. However, the presence of tetracycline antibiotics residues in food is a serious public health concern because of the harmful effects of these residues on consumer's health. Therefore, it is necessary to detect tetracycline residues in food of animal origin keeping in view the food safety issues and probl...

Shitandi, A. 2004. Risk factors and control strategies for antibiotic residues in milk at farm level in Kenya. Doctoral dissertation. ISSN 1401-6249. ISBN 91-576-6477-3. Antibiotic residues in milk in Kenya constitute a problem and there is strong interest to enhance milk safety. The research sought to establish whether the prevention of residues in milk was viable at the farm level. It also ev...

How do enzymes achieve substrate specificity? More specifically, how do structural elements and individual residues contribute to substrate recognition? Serine βlactamases are an interesting model to study the effect of exchange of individual residues on specificity because new enzyme variants with extended substrate spectra are a major cause of increasing antibiotic resistance of pathogenic ba...

conclusions: the combination of plasmid profiling and php techniques revealed the presence of diverse population of vre in sewage treatment plant in tehran. furthermore, the results showed that the php technique is a reliable method in determining the vre clonal diversity. results: all isolates were found to be resistant to erythromycin, ampicillin and ciprofloxacin. the pcr analyses showed tha...

In this study, a series of mastoparan analogs were engineered based on the strategies of Ala and Lys scanning in relation to the sequences of classical mastoparans. Ten analog mastoparans, presenting from zero to six Lys residues in their sequences were synthesized and assayed for some typical biological activities for this group of peptide: mast cell degranulation, hemolysis, and antibiosis. I...

Antibiotics are used in poultry farms to enhance growth, feed efficiency and reduce diseases. However, their irrational and non-moderate using can cause serious problems for the consumer and the manufacturer. The aim of this study is to estimate antibiotics residues in poultry (chicken and turkey) tissues collected from broiler farms in Meknès Morocco. For this purpose, 120 poultry meat samples...

A novel electrochemical immunosensing strategy for the detection of sulfonamide antibiotics in milk based on magnetic beads is presented. Among the different strategies for immobilizing the class-specific anti-sulfonamide antibody to the magnetic beads--such as those based on the use of Protein A or carboxylate modified magnetic beads - ,the best strategy was found to be the covalent bonding on...

background: antibiotics are an important class of drugs which are commonly used in veterinary for therapeutic, prophylactic and growth promotion purposes. antibiotic consumption may leave some residues in livestock food products leading to human health problems as well as failure in fermentation processing. the objective of this study was to investigate the antibiotic consumption pattern in ani...

Prevention of antibiotic residues in milk is an important aspect in milk production to ensure health protection for the consumer and high quality of milk for dairy processing. Limited information is available on the potential impact of milking frequencies associated with Automatic Milking (AM) on excretion of veterinary drugs in milk. Under experimental conditions the excretion of antibiotics i...
