We developed a simple and effective polydiacetylene-based, label-free multiplex DNA chip for the detection of various pathogenic microorganisms. A novel immobilization method of PDA vesicles on glass slides was exploited using α-cyclodextrin (α-CD). The surface topography of the efficiently immobilized PDA vesicles was confirmed using scanning electron microscopy (SEM) and atomic force microsco...

The rapid and accurate quantification of the pathogenic bacteria is extremely critical to decrease the bacterial infections in all areas related to health and safety. We have developed an electrochemical strategy for simultaneous ultrasensitive detection of E. coli O157:H7 and Vibrio cholerae O1. This approach was based on the specific immune recognition of different pathogenic bacteria by mult...

AIM The study aimed to determine qualitative and quantitative contamination of dental unit reservoir water with aerobic and facultative anaerobic bacteria, with regards to health risk to dental staff and patients. MATERIALS & METHODS The study material included water samples from 107 unit reservoirs. Conventional microbiological methods were used. The isolated bacteria were divided into three...

OBJECTIVES The aim of this study was to characterize the pathogens responsible for causing diarrhea according to season, region of isolation, patient age, and sex as well as to provide useful data for the prevention of diarrheal disease. METHODS Stool specimens from 14,886 patients with diarrhea were collected to identify pathogenic bacteria from January 2014 to December 2014 in Korea. A tota...

background :  a large number of plants are used for treatment of diseases because of their antimicrobial activities. this study aims to investigate the antimicrobial effects of some plants on the food pathogenic bacteria.   methods : plant extracts were obtained using the rotary system, the minimum inhibitory concentration (mic) by diluting method against bacteria was determined.   results :   ...

conclusions preliminary results indicate that the native iranian actinobacteria could be considered a suitable option for screening of the new antibacterial compounds. molecular research and antibacterial compound extraction against the aforementioned pathogenic strains are also being conducted. results based on the morphological characterization, 35 isolated cases belonged to actinomycetes and...

Long before bacteria infected humans, they infected amoebas, which remain a potentially important reservoir for human disease. Diverse soil amoebas including Dictyostelium and Acanthamoeba can host intracellular bacteria. Though the internal environment of free-living amoebas is similar in many ways to that of mammalian macrophages, they differ in a number of important ways, including temperatu...
