Rapid identification of microorganisms in blood cultures is required to optimize empirical treatment at an early stage. Fluorescence in situ hybridization (FISH) can reduce the time to identification of microorganisms in growth-positive blood cultures. In this study, we evaluated the performance, time to identification, and potential clinical benefits of FISH compared to those of conventional c...
Background & Objective: Aromatic hydrocarbons are produced by incomplete combustion of fossil fuels and pollute the soil following the emission into the atmosphere by precipitation. Numerous studies suggest that microbial inoculation has contributed to biodegradation of aromatic hydrocarbons. However, other studies have not confirmed the efficacy of this procedure in biodegradation. Regarding t...
Here, we review what is known about the microorganisms present in raw milk, including milk from cows, sheep, goats and humans. Milk, due to its high nutritional content, can support a rich microbiota. These microorganisms enter milk from a variety of sources and, once in milk, can play a number of roles, such as facilitating dairy fermentations (e.g. Lactococcus, Lactobacillus, Streptococcus, P...
Certain important industrial fermentations require substantial amounts of sterile air that are commonly obtained by filtration through beds of fibers, granular solids, or specially prepared filter media (Gaden and Humphrey, 1956). To control the efficiency of such sterilization filters, several methods to estimate the microorganism content of the air have been proposed. These methods can be cla...
results patients between 35 and 44 years of age were most frequently affected (25.00%) by otitis externa (average age, 43.87 ± 18.08 years). moreover, women (54.31%) were more frequently affected than men (45.69%). upon direct investigation, gram-positive bacilli were the most commonly identified microorganisms (22.41%). furthermore, bacillus spp. and coagulase-negative staphylococci (22.41% an...
Background and aims: Staphylococcus aureus is one of the most common foodborne pathogens, which is far more isolated from hospital foods and plays a key role in food poisoning. This study was conducted to investigate the prevalence of Staphylococcus aureus strain isolated from the foods of patients’ gavage samples and to determine their antibiotic resistance patterns in a military hospital in T...
Introduction: Chitosan has the property of inhibition of the growth of many pathogenic bacteria and fungi. Tissue conditioners are good substances for the growth and colonization of a variety of micro-organisms. The aim of this research was to investigate the antibacterial and antifungal properties of Chitosan, ZnO and Ag nanoparticles added to tissue conditioners. Methods: In this clinical tr...

Background and purpose: Hospital-acquired pneumonia (HAP) is the most commonly-acquired infection in patients in intensive care units and related to a high mortality rate. Due to differences in type of microorganisms and their resistance pattern, this study was conducted to determine profile of microorganisms and their resistance pattern for initiation of more effective empirical therapy.
