Persistence of microorganisms or reinfections are the main reasons for failure of root canal therapy. Very few studies to date have included culture-independent methods to assess the microbiota, including non-cultivable microorganisms. The aim of this study was to combine culture methods with culture-independent cloning methods to analyze the microbial flora of root-filled teeth with periradicu...
BACKGROUND Necrotizing soft tissue infections (NSTIs) are a group of infections affecting all soft tissues. NSTI involves necrosis of the afflicted tissue and is potentially life threatening due to major and rapid destruction of tissue, which often leads to septic shock and organ failure. The gold standard for identification of pathogens is culture; however molecular methods for identification ...
The objective of this study was to determine the frequency of microorganisms isolated from blood samples of patients admitted to Intensive Care Unit (ICU), and the rate of their resistance to common administered antibiotics in an Iranian ICU. One-hundred patients with Systemic Inflammatory Response Syndromes (SIRS), hospitalized in ICU of Sina Hospital, Tehran, Iran, were entered to this cross-...
The main purpose of this research is studying the possibility of bioremediation of polycyclic aromatic hydrocarbons (PAHs) contaminated soils in Iran’s tar refinery area located in Isfahan. For many years a great quantity of tar produced by neighboring metallurgical plant has been stored in lagoons as natural reservoirs, causing the contamination of soil in this area. Microorganisms capable of ...
Background and Aim: Although antibiotics are used in the treatment of infectious diseases, there are many problems such as adverse drug reactions and resistance to antibiotics. Plants, which may have less adverse reactions, can be a suitable substitute for chemical drugs. Cichorium intybus L. is one of the herbs that can be easily found in many areas of Iran. Since Cichorium intybus L. has anti...

OBJECTIVE Microbiological examination of donated human cardiac tissue is a necessary procedure for Heart Valve Banks to determine the biological safety of preserved allografts. Test protocols must be validated to prevent false-negative outcomes that pose a risk of infection to recipients of the tissue. The Heart Valve Bank in Rotterdam evaluated a validated, alternative entry test for donated t...
