Description
| - Tularaemia caused by inhalation of type A Francisella tularensis bacteria is one of the most aggressive infectious diseases known, but the reasons for the very rapid spread of the organism from the lungs to internal organs and the ensuingmortality are unknown. The present study used the mouse model to examine in detail the host immune response in the lung. After an aerosol challenge with 20 c.f.u. of the type A strain FSC033, all mice developed clinical signs of severe disease, showed weight loss by day 4 of infection and died the next day. Histopathological findings in the lung revealed acute inflammation and intense vasculitis and perivasculitis on day 4. Gene transcriptional changes in the mouse lung samples were examined on days 1, 2 and 4 of infection using a cDNA microarray with 20,600 mouse clones representing 18,500 genes. In total, 424 genes were found to be differentially expressed, some of which were both up- and downregulated at different time points, 192 of which were upregulated and 234

- Tularémie vyvolaná inhalací typem A Francisella tularensis je jednou z nejagresivnějších, známých onemocnění, nicméně příčiny rychlého šíření mikrobů z plic do vnitřních orgánů a z toho vyplývající mortalita jsou neznámé. V předložené studii byl použit myší model pro analýzu hostitelské imunitní reakce v plicích. Aplikace aerosolové infekce v dávce 20 c.f.u. subtypem A kmen FSC033 vedla u všech myší k vývoji klinických znaků závažného onemocnění. Všechny myši vykazovaly váhový úbytek 4. den po infekci a následující den zemřely. Histopatologický nález v plicích 4. den po infekci prokázal akutní zánět a intenzivní vaskulitidu a perivaskulitidu. Změny v genové transkripci v myších plicích byly analyzovány 1., 2. a 4. den po infekci pomocí cDNA microarray obsahujících 20,600 myších klonů reprezentujících 18,500 genů. Celkově byla prokázána změna exprese u 424 genů v různých časových intervalech, z nichž některé geny byly přepisovány ve zvýšené míře, u jiných pak byla transkripce zeslabena. Bylo zjištěno, (cs)
