lead to the so-called ‘superinfection’, which results in higher virulence and pathogenicity due to recombination events of the viral genomes ( Kann et al., 2006; Beczkowski et al., 2015 ). To test a cat’s infection status, point-of-care enzyme

The present study reports on the location of major foci of footrot in goats in the Extremadura region of Spain by the determination of locally occurring strictly anaerobic microorganisms involved in the pathogenesis and development of this disease. The most commonly isolated microorganisms belonged to the genera Dichelobacter, Fusobacterium, Porphyromonas and Prevotella; these were found in conjunction with other species of minor importance. The species most frequently isolated were Fusobacterium necrophorum (40%), Dichelobacter nodosus (31.7%), Porphyromonas asaccharolytica (21.1%) and Prevotella melaninogenica (12.9%). Virulence factors identified in the isolated microorganisms included haemolysins, elastases and lecithinases, which enabled the organisms involved to initiate and/or aggravate the disease. Serotyping was performed for Dichelobacter nodosus isolates, since this species is responsible for triggering the process of infection. A and C were the most frequently isolated serovarieties (representing 40.7% and 25.9% of the cases, respectively).

Better vaccines and new therapeutic drugs could be a successful breakthrough against intracellular bacteria. M. tuberculosis ABC transporter ATPase (Rv0986) plays a role in mycobacterial virulence by inhibiting phagosome-lysosome fusion. Thus, it could be a potential vaccine candidate. C. pneumoniae another important intracellular bacterium possesses a protein named CpB0255, which is homologous with the mycobacterial Rv0986. The aim of this study was the cloning, over-expression and purification of CpB0255 ABC transporter ATPase protein to study its biological properties. The immunogenicity and protective effect of recombinant chlamydial ATPase protein combined with Alum adjuvant were investigated in mice. The immunization resulted in the reduction of the number of viable C. pneumoniae in the lungs after challenge. Our results confirm that chlamydial ATPase induces protective immunity in mice.

A létfontosságú szervek elégtelenségének kezelésében a szervtranszplantáció a napi gyakorlat része. A recipiensek közös jellemzője, hogy immunszuppresszív kezelést igényelnek a szervkilökődés megakadályozása érdekében. Az immunszuppresszió növeli az infekcióhajlamot, különösen az egyébként alacsony virulenciájú opportunista kórokozókkal szemben. A szervtranszplantáltak fertőzéseinek jelentős része a tüdőt és a légutakat érinti. Az infekciós komplikációk felismerésében a pulmonológiai diagnosztika, magas szintű mikrobiológiai eljárások és a különböző képalkotó technikák alkalmazhatók. A terápia fejlődése és elérhetősége elengedhetetlen az infekciók eredményes kezeléséhez. Tekintve, hogy a szervtranszplantáltak száma folyamatosan nő, az orvos mind nagyobb számban találkozhat vese-, máj-, szív- vagy tüdőtranszplantált betegek pulmonalis komplikációival. Orv. Hetil., 2012, 153, 899–903.
