Problematika infekčních chorob v povědomí žáků základních a středních škol. / Awareness of contagious disease in mind of pupils at basic and secondary schools.Peštová, Ilona January 2010 (has links)
Infectious diseases are a very hot topic nowadays in society. In recent years, there were several epidemics, infectious diseases (hepatitis A, Avian influenza, pandemic influenza A) and nobody knows when will the next "new" infection. At the outbreak of epidemics, there is great interest in the company to obtain information about the disease, but often also to unnecessary panic, because the media often publish incorrect information. It would be preferable, in order to improve public awareness and prevent the unnecessary spread of disease. Great emphasis should be given to prevent the disease - primarily on immunization, hygiene rules and principles of safe sex. Quality information should be mainly from teachers in teaching their pupils, as is clear from research books, infectious diseases are only mentioned in textbooks and the number of substantive information in them is missing. The fact that pupils of primary schools and grammar schools with basic information on infectious diseases do not meet in the classroom, evidenced by the results of a survey carried out in the 6th classes and first year at selected elementary schools and grammar schools in Prague. To raise awareness of the pupils in school was to create a methodical manual for teachers, which summarizes information about bacterial and...

Characterisation of Fusarium oxysporum species complex associated with Fusarium wilt of sweet potato in South AfricaNkosi, Brightness Zama 08 1900 (has links)
Sweet potato is a popular food security crop in South Africa and has a considerable commercial value. Fusarium wilt (FW), caused by the fungal pathogen Fusarium oxysporum formae speciales (f. sp.) batatas, has been reported worldwide and is widespread in sweet potato production areas in South Africa. Preliminary molecular identification of South African isolates from diseased sweet potato plants indicated that there are other formae speciales besides F. oxysporum f. sp. batatas associated with FW. The objectives of the study were to conduct a field survey and to characterise the isolates of the Fusarium oxysporum species complex (FOSC) using phylogenetic analyses, morphological characterisation and DNA barcoding. Phylogenetic analyses revealed two other formae speciales, namely F. oxysporum f. sp. tuberosi and F. oxysporum f. sp. vanillae that were associated with FW. This study has contributed in understanding and knowledge of FOSC associated with FW of sweet potato in South Africa. / Life and Consumer Sciences / M. Sc. (Life Sciences)
