Introduction: Periprosthetic joint infections (PJI) are increasing as a result of increased major joint arthroplasty (MJA). Classical treatment of PJI is a two-stage revision. However, this approach results in morbidity and is not cost effective. We investigated whether covering of the implants with bone cement is sufficient for eradication of microorganism on biofilm. Materials and methods: 24...

background and objectives: psychrotrophic bacteria can produce enzymes at low temperatures; this provides a wide biotechnological potential, and offers numerous economical advantages over the use of mesophilic bacteria. in this study, extracellular protease production by psychrotrophic rheinheimera sp. (km459533) was optimized by the response surface methodology. materials and methods: the cult...

Purpose: The purpose of the present study was to develop a novel selective medium (OVSM) and useful identification method for oral Veillonella species, assess prevalence this species using medium, investigate whether monitoring levels is as clinical indicator diagnosis halitosis. Methods: To examine bacterial populations in cavity, multiplex PCR were developed isolating identifying species. OVS...

BACKGROUND AND OBJECTIVES Entomopathogenic nematodes, belonging to the family heterorhabditis and steinernematidae, are reported to be symbiotically associated with specific bacteria and the secondary metabolites produced by these bacteria possess antimicrobial activity. In this study, bacteria were isolated from nematodes belonging to the family rhabditidae, and the antimicrobial activity was ...

More than 90% of the surviving cells of Escherichia coli NCSM were injured after freezing in water at -78 C. Injury was determined by the ability of cells to form colonies on Trypticase soy agar with yeast extract but not on violet red-bile agar and deoxycholate-lactose agar. Exposure of the injured cells to Brilliant Green-bile broth and lauryl sulfate broth prevented subsequent colony formati...
