Biogenic amines were determined by HPLC in four beer types. In spontaneously fermented beers (SF beers), the amounts of vasoactive amines reached high levels, namely a mean value (1) above 20 mg/l for tyramine and (2) close to 10 mg/l for histamine. Considering the bacterial origin of these amines, we established a calculation formula for a Beer biogenic amine index (Beer BAI), reflecting the m...

background: contamination of swimming pools’ water can lead to the transfer of different diseases to humans. the aim of this study was to investigate the quality of water in kerman swimming pools. methods: in this cross-sectional study, sampling from swimming pools was performed before and after swimming, every week. total number of samples collected was 150 samples. samples were investigated i...

conclusions a high prevalence of sleep disorder was found in this population, specifically among female students. analysis of the relationship between sleep disorder and academic performance indicates a significant relationship of psqi scores with marital status, habitat, smoking, physical activity, and academic performance. results a total of 177 respondents, with a response rate of 55%, were ...

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...

Microbiological food safety surveillance is a system that collects data regarding food contamination by foodborne pathogens, parasites, viruses, and other harmful microbiological factors. It helps to understand the spectrum of food safety, timely detect food safety hazards, and provide relevant data for food safety supervision, risk assessment, and standards-setting. The study discusses the mic...

the development of a surface water evaluation index is a critical factor in the assessment, restoration and protection of stream water quality. quantifying water pollution in specific grade using dominant parameters is important, as this can explain the current state of water pollution with accuracy. as a result, an integrated multi-parameter water quality index has been developed. it is based ...

The microbiological quality of 75 private drinking water supply boreholes in Co. Cork, Ireland was assessed in order to determine the incidence of contamination and the potential pathways of such contamination. Microbiological analysis was carried out using the membrane filtration technique for the recovery of thermotolerant (faecal) coliforms. The sanitary protection of the supplies was evalua...
