Prevention of nosocomial infections origin and spreading in Český Krumlov a.s. hospital
The present Bachelor thesis focuses primarily on the prevention of occurrence of hospital-acquired infections and the causes of spread of these infections across healthcare facilities. The thesis relies on active communication with the coordinator for management of quality and safety of nursing care, who helpfully provided me with valid information and documents relating to the system of hospital-acquired infection prevention, and arranged for sampling for microbiological examinations in postoperative care departments (ONP) - ONP II and ONP - C III, the hospital Nemocnice Český Krumlov a.s. The Bachelor thesis consists of a theoretical part and a practical part. The theoretical part summarizes knowledge related to nosocomial infections as such, the division and manner of transmission, with an emphasis of prevention of occurrence of these infections and spread of the same among "healthy hospitalized persons." The practical part explores the hospital's approved internal documents aimed at prevention of nosocomial infections and training of staff in the healthcare facility. Moreover, the practical part also verifies the prevention of nosocomial infections by means of microbiological tests. The entire research was carried out in cooperation with two hospitals: Nemocnice Český Krumlov a.s., i.e. the location of sampling, and Nemocnice a.s. Prachatice, the location of microbiological processing. The laboratory-based research part was solved in a microbiology laboratory in the hospital Nemocnice Prachatice a.s., with the aim of identifying the individual microorganisms from the smears taken in the postoperative care department in the hospital in Český Krumlov. These smears reflect the quality of the performed hygiene in connection with the risk of occurrence of nosocomial infections. In addition to laboratory-based research activities, the present thesis also examines the current quality and processing of the hospital's internal documents relating to the prevention of nosocomial infections and the training schedule for the hospital's staff in this respect - trainings are conducted on an annual basis. The thesis is concluded by a summary of isolated microorganisms and comparison of these microorganisms in the framework of the two hospital departments. Last but not least, the presence of highly infectious agents for occurrence of nosocomial infections is excluded on the basis of valid legislation. The thesis also provides a result of qualitative processing in a form of recommendations e.g. for improvement of purpose-directed cleaning. The thesis may therefore be used as a tool for improving awareness of this problem area.
Microbial contamination of photographic materials
Ouředníčková, Veronika ; Dzik, Petr (referee) ; Veselá, Mária (advisor)
This diploma work is focused on a study of microbial contamination of photographic materials. In the first part of this work the information about the archive and museum microbial contaminations were collected. The most frequent contaminants of photographic collections – Penicillium chrysogenum and Aspergillus niger were studied. Their activity on photographic papers Fomaspeed and Fomabrom was evaluated. It was found that at the given experimental conditions the image layers of Fomaspeed paper are resistant to fungi mycelium growth. On the other hand, the Fomabrom paper image layer was irrecoverably damaged by action of fungi mentioned above. The degree image layer deterioration was evaluated with the aid of sensitometric curves.
Optimization of chloramination based on raw water quality and operational conditions of a water treatment plant
Švec, Pavel ; Látal,, Milan (referee) ; Dolejš, Petr (advisor)
The most difficult part of water treatment is to ensure that water will be delivered to consumer in unchanged form and hygienic unexceptionable. To hygienic safety is using doses of chlor, whiches are deadly for organisms and inhibite their proliferation in pipeline. Modern way how to clear water from organism is called chloramination. By the help of ammonium salts chlor is released in sequence. So large single-shot doses of chlor aren´t necessary. Due the big dose was THM and another dangerous compounds formed.
Disinfectants in food
Romanská, Veronika ; Vítová, Eva (referee) ; Vránová, Dana (advisor)
The aim the of bachelor thesis is description of chemical disinfection, which is used in food industry to eliminate microbial contaminations of food, food intermediates and foodborne diseases, which can occur if hygienic regulations are not observed correctly. The experimental part of the bachelor thesis characterizes the method which was used to specify the disinfecting effect. This method was used to determine two types of disinfectants which contain two different active ingredients. Based on the results, two disinfectants were evaluated and compared.
Risk assessement as a method for evaluation of preventive and crisis measures in the control of avian influenza in the Czech republic
The topic of my bachelor thesis is: {\clqq}Risk assessment as a method for evaluation of preventive and crisis measures in the control of the avian influenza in the Czech Republic``. Humanity has already fought with a series of diseases since the beginning of their existence. Recently the avian influenza has come into prominence. The history of the avian influenza, which stroke a wide spectrum of avian kinds, is probably very long, however the public became interested in it after the transmission to a human in Hong Kong in 1997. It has been responsible for hundreds of human deaths since. In my bachelor thesis, I was trying to estimate the possible risks of preventive and crisis measures in the control of the avian influenza in the Czech Republic. The {\clqq}word`` method of risks estimation was used and three possible risks, which could occur during an outbreak of the avian influenza in the Czech Republic, were selected {--} the risk of a human contagion by the avian influenza; the risk of a poultry contagion by the avian influenza and the risk of an outbreak of a pandemic virus. While estimating the risks, activities associated with the liquidation and prevention of the bird flu by the integrated rescue system, activities of the breeders and activities of the public were taken particularly under consideration. In terms of spreading of the disease, activities presenting the least risk seem to be those of the integrated rescue system. This is due to the fact that its members have been given an adequate training and education. The importance of the populace for the possibility of spreading the bird flu seems to be relatively low, however an appropriate degree of foreknowledge is highly recommendable. It was found that in terms of spreading the avian influenza, it is the breeder and other staff members associated with the farm, that are of particular importance. This is especially the case if they are not fully adhering to the appropriate level of disinfection and missing out on duties given by the law.
