Detection of persistent forms of Borrelia burgdorferi sensu stricto in infected mice after antibiotic treatment
RAMZY, Ida
Antibiotic treatment of Lyme disease is a challenging procedure with unexpected outcomes that may arise sometime. According to standard protocols recommended by the Centers for Disease Control and Prevention, USA (CDC) for early Lyme disease, a short course of oral antibiotics cures the majority of cases. This thesis deals with the analysis of the efficiency of 2 majorly used antibiotics, doxycycline and amoxicillin, in elimination of Borrelia infection on laboratory mice model after 2 weeks of treatment. Our results confirmed the presence of persistent forms of spirochetes in mice tissues after antibiotic treatment using the spirochete cultivation method in liquid MKP medium.
Resistance to antimicrobial therapy of Helicobacter pylori strains
Moravcová, Monika ; Keil, Radan (advisor) ; Nyč, Otakar (referee)
Helicobacter pylori (hereinafter referred to as H. pylori) is a gram-negative bacteria which colonises the human stomach mucosa. Its role in the aethiopathogenesis of chronic gastritis, ulcer disorders of the gastroduodenum and MALT-lymphoma has been clearly demonstrated, and in connection with the occurrence of stomach cancer it has been indicated by the World Health Organisation (WHO) as a class I carcinogen. H. pylori infection can be detected from samples of stomach mucosa taken in an endoscopic examination (rapid urease test, microscopic examination, culture), or the non-invasive method can be used (13 C-Urea Breath Test or H. Pylori stool antigen test - HpSA). Effective therapy of H. pylori infection resides in the administration of a combination of antibiotics and a proton pump inhibitor. In recent years the resistance of bacterial strains to used antibiotics has been increasing on a worldwide scale, and we can also observe this trend in the case of H. pylori. If the level of resistance exceeds 20 % for clarithromycin and 40 % for metronidazole, these antibiotics are not recommended for the treatment of an infection caused by this bacteria. In a group of 61 patients at the Department of Internal Medicine at the University Hospital Motol who had undergone an endoscopic examination of the...
