Objective. Compare the effects of three sampling methods on the microbiological monitoring results after reprocessing of gastrointestinal endoscopes, providing scientific basis for improving the monitoring quality of gastrointestinal endoscope cleaning and disinfection. Method. Gastrointestinal endoscopes after reprocessing were selected randomly at the gastrointestinal endoscopy center of a tertiary hospital in Shanghai from October 2018 to February 2019. The endoscopes selected were all sampled in three different methods under continuous sampling and intermittent sampling respectively. Methods used includes, the biopsy channel group (Group A), the entire channel group (Group B), and the disc brush group (Group C). Then the colony forming units (CFU/piece) were counted in the laboratory. Results. A total of 12 endoscopes were sampled by using continuous sampling approach, in which the detection rate of bacteria in disc brush group (33.3%) and entire channel group (33.3%) was higher than biopsy channel group (8.3%). Among the 12 endoscopes sampled with intermittent approach, the detection rate of bacteria from high to low was the disc brush group (50%), the entire channel group (41.7%), and the biopsy channel group (8.3%). Conclusion. Different sampling methods will lead to the difference of microbiological culture results after reprocessing of gastrointestinal endoscope, indicating that the improved sampling method is beneficial to objectively reflect the endoscope cleaning and disinfection effect, and improve the monitoring quality of endoscope disinfection.

Introduction: The association of Mycobacterium chimaera infection in patients undergoing cardiopulmonary bypass (CPB) with the use of heater-cooler units (HCU) has been reported in various literature. We described microbiological monitoring and the extent of microbiological contamination of HCUs utilized in our centre and strategies employed to reduce the high microbial load. Methods: Since August 2016, we have been following the new Instructions for Use from the manufacturer for the cleaning and disinfection of three units of Stöckert 3T and four units of Stöckert 1T HCU at the National Heart Centre Singapore. Microbiological monitoring began in January 2017 and included acid-fast bacilli (AFB) culture, Pseudomonas aeruginosa, total colony and total coliform count. Methods, such as increasing disinfection frequency and making the HCU inactive by keeping it empty in storage, were used to reduce the high colony count. Results: All three units of Stöckert 3T and two units of Stöckert 1T were contaminated with Mycobacterium chimaera. Pseudomonas aeruginosa and total coliform count were consistently <1 colony-forming unit (CFU)/100 mL in every water sample of each HCU. High colony counts were encountered initially in all units. Step-up frequency of disinfection was found to be not as effective as keeping the HCU inactive in bringing the total colony count to an acceptable level. Conclusions: All monitoring and maintenance measures of HCUs need to be established and maintained to mitigate potential infection risks to patients. Strict adherence to all cleaning and disinfection processes and keeping the HCU inactive maintained the water quality of the HCU at acceptable levels.

Decision making is an individual activity that is directly involved in obtaining and using the goods offered. Promotion is one of the variables in a marketing mix that is very important to be implemented by a company in marketing its products or services, thus influencing consumers to make purchasing decisions. The quality of the product can also affect consumers in making purchasing decisions. This study aims to analyze the effect of product quality and promotion on purchasing decision of Melon fruit. Population and sample of research is purchasing or buyer from consumer of PT. Syafina Niaga as many as 30 companies and sampling methods using saturated sampling techniques as well as analysis used with regression analysis. The results showed that there is a significant influence between product quality and promotion of purchasing decisions.

Mangroves are classified as permanent preservation areas and regarded as natural nurseries. However, they have suffered several anthropogenic stresses, resulting in their decline. In the light of that, comes the importance of researching their environmental characteristics and revealing possible factors that have led to the degradation of this important ecosystem. The aim of this study was to evaluate the environmental quality of different areas in the mangroves of Ilha do Lameirão Ecological Station through microbiological analyzes of sediment and interstitial water along ten (10) sites, distributed in two areas with different conservation levels (Canal dos Escravos (CE) and Maria Ortiz (MO)) between 2010 and 2012. The microbiological analyzes revealed that MO region, in all seasons of the year, achieved total coliform and thermo-tolerant coliform values above those permitted by the CONAMA Resolution 357/05, fitting the Class 2 conservation standard. The presence of high levels of total and thermo-tolerant coliforms in MO is a strong indicator of impacts originated from the human population and, consequently, the decline of the mangrove itself and the health of human communities surrounding that area.

Hygienic Conditions

The aim of this study is to evaluate the hygienic quality of the dishes cooked and sold by the women traders in the town of Korhogo. The study was carried out with 45 restaurants in the town of Korhogo. It consisted on the one hand, a survey based on the Ishikawa diagram in order to assess the hygienic conditions, and on the other hand of microbiological analyses of the ready-to-serve meals. A total of 90 samples were taken, including 2 dishes per restaurant, respectively consisting of one hot and one cold dish. Generally, results showed that hygienic conditions were unsatisfactory based on the utilized guidelines. From a microbiological point of view, the meal samples were 75.2% satisfactory, 7.6% acceptable and 17.2% unsatisfactory. In view of these results, it appears essential to improve hygiene conditions by greater involvement of the official services involved in training these traders and monitoring compliance with good hygiene practices and the establishment of a program of cleaning and disinfection of premises and equipment.
