Background and aim: Use of laser technology in endodontics has greatly increased in the recent years due to the introduction of new wavelengths and methods and optimal antimicrobial and smear layer removal properties of lasers. This in vitro study aimed to compare the antibacterial effects of diode lasers of 810 nm and 980 nm wavelength on Enterococcus faecalis (E. faecalis) biofilm in the root...

The influence of nature of the feed sample, feeding frequency and pore size on the influx of bacteria and protozoa into synthetic fiber bags suspended in the rumens of sheep fed different diets was studied. Counts of total culturable bacteria in bags with a pore size of 10 microns were less than 30% of the ruminal counts for animals that were fed the lucerne hay and high-roughage diets. The max...

BACKGROUND The high numbers of heterotrophic microorganisms that have been cultured from dental unit waterlines (DUWs) have raised concern that this water may exceed suggested limits for heterotrophic plate counts (HPCs). The main purpose of this investigation was to examine HPC variability in DUWs and to examine in detail the effect of laboratory processing of water samples on HPC values. ME...

Effect of UMMB supplementation on rumen profile in buffalo calves was undertaken with the objectives to study the effect of UMMB on rumen microbiology and rumen metabolites. Eight apparently healthy male buffalo calves of 10 to12 months age and weighing between 100 to 150 kg were used as experimental animals. They were divided in to control and treatment groups consisting of 4 animals in each g...

Background Dental plaque is one of the predominant causes of major oral diseases. Although mechanical and chemical methods are extensively followed to control the development of plaque, plaque-related diseases still persist. Therefore, this necessitates for alternative measures of plaque control, one such alternative is photodynamic antimicrobial chemotherapy (PACT). Materials and Methods Spl...

OBJECTIVE Following tissue barrier breaches, interleukin-33 (IL-33) is released as an 'alarmin' to induce inflammation. Soluble suppression of tumorigenicity 2 (sST2), as an IL-33 decoy receptor, contributes to limit inflammation. We assessed the relationship between the IL-33/ST2 axis and markers of gut mucosal damage in patients with early (EHI) and chronic HIV infection (CHI) and elite contr...

nonpasturized cream is usually contaminated with different types of pathogens, and its use in foodstuffs such as creamy cake and ice-cream is the main cause of contamination of such foodstuffs. the purpose of the analysis was to show the contamination rate of nonpasturized cream and foodstuffs in which such creams are used. studies carried out on 70 samples from 231 distribution centers, from d...

UNLABELLED This study investigated the capability of three rapid microbiological methods to detect microorganisms in aseptically prepared pharmacy preparations at National Health Service hospitals in the United Kingdom. BacT/ALERT 3D (bioMerieux), AKuScreen (Celsis), and BactiFlow ALS (AES Chemunex) technologies were used to detect levels of microorganisms in pharmaceutical products. Four produ...

Microbial testing performed in support of pharmaceutical and biopharmaceutical production falls into three main categories: detection (qualitative), enumeration (quantitative), and characterization/identification. Traditional microbiological methods listed in the compendia and discussed by using the conventional growth-based techniques, which are labor intensive and time consuming. In general, ...
