Abstract

Abstract Background and objectives: Blood culture is a critical part of evaluation of Neonate suspected wath Septicaemia. This phenomenon is one of the most important causes of neonates in Neonatal. Material and Methods: This study was carried out on 1470 somples of neonates suspected with bacteraemia , using reutine microbiologicul technique. The samples wene assessed in hazrate Masoomeh hospilal of Kermansha,Iran. Results and Conclusions: of all samples, 112 (7.62%) ane pasitive. Most of the Positive cultures were obtained after 24 hours of incubation in broth mediu. we Confirmed this result by using diseriminafiue culture media the Isolated bacteria are Coagulase-negative Staphylococus(28.6%),Alfahymolylic Streptococus(0.09%), staphylococus aureus(10.7%),Klebseilla(6.2%),pseudomonas(12.5%),moraxella(0.9%),acin eto bacter(13.4%), Alcalingenes(13.4%),protenos(1.8%) and salmonela (0.9%). Conclusion: the frequency of Coagulase-negative Staphylococus Isolated from neonates Blood culture is more than the other micro organisms. Generally, the frequency of gram negative bacteria is higher than gram Positive. Key words: Septicaemia, Blood culture, Bacteraemia, Neonatal

Abstract

Abstract Background and Objective: This study was aimed to determine the extent of bacterial contamination and drug resistance patterns of isolates colonized in colonoscope and endoscope and in relevant personnel. Material and Methods: A total of 107 samples were obtained from staff of endoscopy and colonoscopy units (SEU and SCU) and gastroenterological imaging equipment. For isolation and identification of the bacteria, swab culture method and biochemical identification test were used, respectively. Antimicrobial resistance profiles, multi-drug resistance (MDR) patterns and phenetic relatedness of these isolates were also analyzed according to standard methods. Results: Most frequent pathogenic bacteria among the SEU and gastroenterological imaging related equipments were included S. aureus (20.8 % and 0 %) Enterococcus spp. (0 % and 5.4%) Pseudomonas spp. (0% and 13.5 %), and Clostridium difficile (0% and 12.5%). Analysis of resistance phenotypes showed a high frequency of MDR phenotypes among the SEU (82.1%), and also in endoscopes, colonoscopes, and other equipments (20%, 50% and 100%, respectively). Phylotyping of S. epidermidis isolates showed the role of staff in transmission of resistance strains to medical equipments and also circulation of strains with identical resistance phenotype among the studied samples. Conclusion: High frequency of pathogenic bacteria in colonoscopes, endoscopes and in the staff of endoscopy & colonoscopy units, and also contamination of these instruments with MDR pathogens emphasize the need for proper disinfection of endoscopes and colonoscopes and also instruction of staff in these units. Key words: Bacterial Contamination Endoscope Colonoscope Antimicrobial Resistance Gastrointestinal Disease.

Abstract

Background and objectives: Gouda Cheese is regarded as a high quality and one of the most popular cheeses in the world. The defining characteristics of Gouda cheese are its yellow color, great aroma and taste of caramel sweetness. The cheese should be well chilled before waxing, to get better seal. The seal is very important to prevent contamination with molds and putrefactive bacteria. Cheese wax is made from paraffin with additional microcrystalline to make pliable for better seal. The aim of this study was to investigate antibacterial effects of Gouda cheese wax.
Methods: Gouda cheese wax samples were collected from four different manufacturers in Iran. The total count of coliforms, Escherichia coli, Salmonella, coagulase-positive Staphylococcus and mold and yeast on the samples was determined. The antimicrobial activities of Gouda cheese wax against E. coli, S. aureus, Saccharomyces cerevisiae, Aspergillus brazilissis and Salmonella enterica were investigated by determining minimum bactericidal concentration and minimum inhibitory concentration.
Results: The results indicated that all Gouda cheese wax samples were prepared in accordance with the national standards. In addition, the examined wax samples had no antimicrobial properties against the tested microorganisms.
Conclusions: The wax used in production of Gouda cheese in Iran has no antimicrobial properties.
