Detection of human respiratory DNA viruses in the respiratory tract samples of immunocompromissed patients.
Blagoevová, Kateřina ; Hubáček, Petr (advisor) ; Hirsch, Ivan (referee)
Respiratory tract diseases are of the most common infectious diseases among both children and adult population all over the world. Viruses are the most frequent cause of respiratory diseases. In healthy immunocompetent individuals respiratory infection proceeds mostly without major complications. Immunocompromissed hosts, for example patients after transplatation, are more susceptible to infection and even common infection may be life threatening for them. Human polyomaviruses KI (KIPyV) and WU (WUPyV) and human bocavirus (HBoV) are most frequently detected in the respiratory tract of patients with acute respiratory tract infection primarily in children and in immunosuppressed patients. However, clear causative link between presence of these viruses and the respiratory disease has not been established. In this retrospective study were tested by quantitative real-time PCR 822 (745 from adults and 77 from children) respiratory samples from 380 immunocompromissed patients included 326 adults and 54 children. Viruses were also detected in the 84 peripheral blood samples. The most frequently detected virus was HBoV (6,32 % positive pacients), followed by KIPyV (5,79 % positive pacients) and WUPyV (0, 53 % positive patients). Only HBoV was detected in blood samples. The study confirmed the presence of KI...

Detection and pathological impact of human Parvovirus B19 in the general population and in the immunocompromissed host
Dubišová, Mária ; Hubáček, Petr (advisor) ; Šmahelová, Jana (referee)
Parvovirus B19 is a non-enveloped single-stranded DNA virus, belonging to the Parvoviridae family. Despite parvoviruses are one of the smallest DNA viruses, some of them are able to infect humans. In general, most of humans experienced parvovirus B19 infection. In case of infection in healthy individual there are usually no complications. Most frequently infected are children and their symptomatic infection is known as fifth disease - erythema infectiosum (EI). However, serious complications may occur if infected person suffers from erythropoiesis disorders, weakened immunity or is pregnant. This thesis aimes the structure of the virus, the course of the infection, infectious diseases caused by parvovirus B19 and particular genotypes especially to pathogenesis of specific disorders. Key words: Parvovirus B19, single-stranded DNA virus, erythroid progenitor cells, Gb4, imunokompromissed host, anemia
