AIM: Worldwide data indicate that antibiotics are frequently used inappropriately. The objective of this study was to investigate the extent of storage and wastage of antibacterial agents in households in Novi Sad, Serbia. METHODS: The study was performed in 8 months period (December 2011-July 2012) in households in Novi Sad, Serbia. The households were randomly selected from the telephone directory. The interviewer performed the survey visiting each household. RESULTS: The total number of antibacterial agents in the 383 surveyed households was 318, constituting 7.3% of the total stored medications. From 383 families included in the study antibiotics were found in 178 (46.5%). In 13 (7.3%) families were found more than one pack of the same antibiotics. The median number of antibacterial agents per household was 1 (range 1-5). The most common antibacterial agents that were not in current use were cephalexin (22.1%) and amoxicillin (16.6%), followed by doxycycline (11.4%), sulfamethoxazole/trimethoprim (11.4%) and amoxicillin/clavulanic acid (9.2%). The percentage of expired antibacterial agents was 20.8%, while 85.2% were not currently in use. CONCLUSION: Antibacterial agents were commonly encountered in Serbian households, and a relatively large percentage was wasted. Informational and educational activities aimed at improving the public knowledge about antimicrobials play the leading role in reducing imprudent use of antibiotics.

The purpose of this study was to improve the survival of Bifidobacterium animalis subsp. lactis 10140 during freeze-drying process by microencapsulation, using a special pediatric prebiotics mixture (galactooligosaccharides and fructooligosaccharides). Probiotic microorganisms were encapsulated with a coat combination of prebiotics-calcium-alginate prior to freeze-drying. Both encapsulated and free cells were then freeze-dried in their optimized combinations of skim milk and prebiotics. Response surface methodology (RSM) was used to produce a coating combination as well as drying medium with the highest cell viability during freeze-drying. The optimum encapsulation composition was found to be 2.1 % Na-alginate, 2.9 % prebiotic, and 21.7 % glycerol. Maximum survival predicted by the model was 81.2 %. No significant (p > 0.05) difference between the predicted and experimental values verified the adequacy of final reduced models. The protection ability of encapsulation was then examined over 120 days of storage at 4 and 25 °C and exposure to a sequential model of infantile GIT conditions including both gastric conditions (pH 3.0 and 4.0, 90 min, 37 °C) and intestinal conditions (pH 7.5, 5 h, 37 °C). Significantly improved cell viability showed that microencapsulation of B. lactis 10140 with the prebiotics was successful in producing a stable symbiotic powdery nutraceutical.
