- Optimization of particle size and encapsulation efficiency of vancomycin nanoparticles by response surface methodology.
- Honary S, Ebrahimi P, Hadianamrei R.Author information Department of Pharmaceutics, Faculty of Pharmacy, Mazandaran University of Medical Sciences , Sari , Iran and.AbstractAbstract Context: Treating vancomycin-resistant Staphylococcus aureus strains requires high doses of vancomycin, which might lead to adverse reactions such as nephrotoxicity and "red neck syndrome". Use of nanotechnology for antibiotic delivery is a promising approach to overcome antibiotic-resistance. Objective: The objective of this study was optimizing the particle size and encapsulation efficiency (EE) of vancomycin nanoparticles prepared from chitosan. Materials and methods: The nanoparticles were prepared by ionotropic gelation method, at different combinations of chitosan concentration, chitosan/tripolyphosphate mass and vancomycin/chitosan mass, using Box-Behnken experimental design. Dynamic light scattering and ultracentrifugation were used to measure the nanoparticle size and EE, respectively. Vancomycin was quantified in samples by spectrophotometery. The optimum conditions were determined by subsequent regression analysis and multicriteria decision analysis of the output data. Results: The nanoparticle size and EE were greatly influenced by the independent variables, which had interactive effects on both responses. The optimum conditions for production of nanoparticles were chitosan concentration of 0.5-1.2 mg/ml, chitosan/tripolyphosphate mass ratio of 3-3.5 and vancomycin/chitosan mass ratio of 1, which yielded nanoparticles between 130 and 150 nm with encapsulation efficiencies of 60-69%. Conclusions: The size and EE of vancomycin nanoparticles were optimized by the proposed procedure.

- Microbiological food safety: a dilemma of developing societies.
- Akhtar S, Sarker MR, Hossain A.Author information Bahauddin Zakariya University Multan, Department of Food Science and Technology , Multan , Pakistan .AbstractAbstract Current food safety issues are deleteriously reshaping the life style of the population in the developing world. Socioeconomic status of the population in poorer economies is one of the major determinants to delineate the availability of safe food to the vulnerable population. Assessment of the prevalence of foodborne illness in developing world is the most neglected area to control disease. Botulism, Shigellosis, Campylobacteriosis, Escherichia coli infection, Staphylococcus aureus infection, Salmonellosis, Listeriosis and Cholerae are extensively prevalent and pose a major threat to human health in underdeveloped communities. The existing food safety status of many African, South Asian, Central, and South American developing countries is distressing therefore; it seems much timely to highlight the areas for the improvement to ensure the supply of safe food to the population in these regions. Extensive literature search at PubMed, Science Direct and Medline was carried out during the current year to catch on relevant data from 1976 to date, using selective terms like food safety, South East Asia, Africa, Central and South America, and foodborne illness etc. Efforts were made to restrict the search to low income countries of these regions with reference to specific foodborne pathogens. This report briefly discusses the present food safety situation in these developing countries and associated consequences as prime issues, suggesting foodborne illness to be the most distressing threat for human health and economic growth.

- The use of nucleosides and arginine as alternative energy sources by coagulase-negative staphylococci in view of meat fermentation.
- Janssens M1, Van der Mijnsbrugge A1, Sánchez Mainar M1, Balzarini T1, De Vuyst L1, Leroy F2.Author information 1Research Group of Industrial Microbiology and Food Biotechnology (IMDO), Faculty of Sciences and Bio-engineering Sciences, Vrije Universiteit Brussel, Pleinlaan 2, B-1050 Brussels, Belgium.2Research Group of Industrial Microbiology and Food Biotechnology (IMDO), Faculty of Sciences and Bio-engineering Sciences, Vrije Universiteit Brussel, Pleinlaan 2, B-1050 Brussels, Belgium. Electronic address: fleroy@vub.ac.be.AbstractThe ability of coagulase-negative staphylococci (CNS) to use alternative energy sources in meat may partially explain their occurrence in fermented meats. Of 61 CNS strains tested, all metabolized adenosine and inosine in a meat simulation medium (MSM). The ability to catabolize arginine via the arginine deiminase (ADI) pathway varied between strains. All tested strains of Staphylococcus carnosus and Staphylococcus epidermidis possessed an arcA gene and showed ADI activity, whereas other species, such as Staphylococcus equorum and Staphylococcus succinus, did not. Arginine catabolic mobile elements (ACME), as in the positive control S. epidermidis ATCC 12228, were uncommon and only found in Staphylococcus xylosus 3PA6 (sausage isolate) and Staphylococcus chromogenes G222 (teat apex isolate). Monoculture experiments were performed in MSM with S. carnosus 833 and SS3-4, S. xylosus G211, and S. epidermidis ATCC 12228 and 2S7-4. At all pH values tested (5.3, 5.8, and 6.5), the strains of S. carnosus catabolized arginine faster than the strains of S. xylosus and S. epidermidis. Only at pH 6.5 could a low ADI activity be found for S. xylosus G211. Increased ADI activity occurred in the case of the ACME-positive S. epidermidis ATCC 12228, when compared to the ACME-negative S. epidermidis 2S7-4.
