The Influence of Pesticides on the Infectivity of Entomopathogenic Nematodes
NERMUŤ, Jiří
It is known that entomopathogenic nematodes rarely live in fields where pesticides and fertilizers are used. Because they are organisms with a high potential for biological and integrated pest control the thesis tried to determine the influence of pesticides on the infectivity and mortality of selected nematodes: Steinernema feltiae, S. arenarium and S. kraussei in water solution of some pesticides. The results are that preparations Vydate (a. i. oxamyl) and Sulka (a. i. sulphur) have the highest negative influence on both characteristics. These pesticides cause a mortality of 94.3 - 99.9 % and reduce infectivity by about 50 {--} 75 % (level 3). The following preparations may be identified as having higher potential for infectivity reduction: above all, Starane 250 EC (fluroxypyr), Sumithion super (fenithrothion), and Novozir MN 80 (mancozeb); on the other hand, Treflan 48 EC (trifluralin) significantly increases mortality. Another important observation is a fact that infectivity is significantly influenced only by concentration of pesticides, not by exposure time. During an experiment with enhacement of resistance to oxamyl (Vydate) I falling mortality and increasing infectivity of entomopathogenic nematodes were observed after five rounds.

The influence of nursing care on the course of hospitalization of the patient with MRSA diagnosis
ŠTVERÁKOVÁ, Martina
The aim of work to find out, how clients with diagnosis MRSA hospitalized in isolation, perceive nursing care from medical staff.

Nosocomial Infections in an In-Patient Department
Kopecký, Jindřich Bc. ; Střítecký, Rudolf (advisor) ; Lešetický, Ondřej (referee)
Nozokomiální infekce jsou v současné době významnou příčinou vzrůstající morbidity a mortality ve všech zdravotnických zařízení. Neznalost či ignorance metod prevence nozokomiálních nákaz může vést k závažnému ohrožení zdraví a života pacienta a výraznému zvýšení nákladů na léčbu. Práce komplexně představuje problematiku nozokomiálních nákaz a jejich efektů na lůžkové zdravotnické zařízení. Pozornost je věnována charakteristice procesu šíření nákaz, popsání současného stavu ve sledování a prevenci nákaz a konečně popsání situace v jedné nemocnici okresního typu.
