dental abscess is a frequently occurring infectious process known to the health practice. the fate of the infection depends on the virulence of the bacteria, host resistance factors, and regional anatomy. serious consequences arising from the spread of a dental abscess lead to significant morbidity and mortality. acute dental abscess is polymicrobial, comprising of strict anaerobes, such as ana...

Antibiotics are the chemotherapeutic agents that kill or inhibit the pathogenic microorganisms. Resistance of microorganism to antibiotics is a growing problem around the world due to indiscriminate and irrational use of antibiotics. In order to overcome the resistance problem and to safely use antibiotics, the correct measurement of potency and bioactivity of antibiotics is essential. Microbio...

During validation and verification of the system for the proper implementation of HACCP principles, it is essential to rely on microbiological data. Considerable science research has been carried out during the last twenty years on sampling and testing of carcasses for hygiene criteria. This includes the preferable indicator microorganisms to be used, in order to indicate the general hygiene of...

In hemodialysis, huge amounts of water are used for diluting the concentrates to produce dialysis fluid. The water is produced on site by reverse osmosis units. The chemical and microbiological quality of the water is essential for dialysis patients. Reverse osmosis units produce water of acceptable chemical quality that can be kept throughout the water system. The microbiological water quality...

Background Endoscopic lung volume reduction (eLVR) is a therapeutic option for selected patients with COPD and severe emphysema. Infectious exacerbations are serious events in these vulnerable patients; hence, prophylactic antibiotics are often prescribed postinterventionally. However, data on the microbiological airway colonization at the time of eLVR are scarce, and there are no evidence-base...

PURPOSE The aim of this study is to evaluate whether periodontopathogens are transmitted from husband to wife or vice versa. MATERIALS AND METHODS We tested the microbiological profile of 9 couples married for at least 10 years suffering from periodontitis. The microbiological analysis provides the quantification by Real-Time PCR of six main periodontopathogens, including P. gingivalis, T. de...

Maintenance of the microbiological quality of water has been used as an important means of preventing waterborne disease throughout the twentieth century. The commonest microbiological tests done on water are for coliforms and Escherichia coli (or faecal coliform). This paper reviews the legislative and other guidance for microbial standards in drinking and bathing waters and considers evidence...

BACKGROUND AND OBJECTIVES Microbiological follow-up is part of quality control of peripheral blood stem cell (PBSC) manipulation. DESIGN AND METHODS We prospectively studied microbiological cultures performed in 865 consecutive untreated autologous PBSC harvests from 348 patients. Our aim was to know the rate of microbiological contamination, the optimum moment to evaluate the sample and the ...

aims: regarding water as the main source of brio, not only its quantity and being availability is vital, but also its quality must be considered. this study was done in order to determine the correlation between physicochemical bod5 and microbiological parameters (fc and tc) in the kashan university of medical sciences wastewater effluent of activated sludge system.  materials & methods: this d...

A confidence interval is an interval (i.e., a range of values) estimate of a parameter of a population (e.g., a mean) calculated from a sample drawn from the population. A confidence interval has an associated confidence level, which is frequency with which a calculated confidence interval is expected to contain the population parameter. Confidence intervals are of interest in modeling and simu...
