Objective(s):Typhoid fever is a dreadful disease of a major threat to public health in developing countries. Vaccination with bacterial immunodominant components such as surface proteins may prove as a potent alternative to live attenuated vaccines. InvH, an important part of needle complex in type three secretion system (TTSS) plays important role in efficient bacterial adherence and entry int...

BACKGROUND We performed quantitative real-time polymerase chain reaction (Q-PCR) to monitor the evolution of Brucella melitensis DNA load from initial diagnosis through post-therapy follow-up in patients with brucellosis. METHODS On the basis of real-time fluorometric quantification of PCR products, we used the ultra-rapid LightCycler system (Roche Diagnostics). We collected 180 peripheral bl...

The diversity and load of heterotrophic bacteria and fungi associated with the mangrove soil from Suva, Fiji Islands, was determined by using the plate count method. The ability of the bacterial isolates to produce various hydrolytic enzymes such as amylase, gelatinase and lipase were determined using the plate assay. The heterotrophic bacterial load was considerably higher than the fungal load...

Co-infection by multiple parasites is common within individuals. Interactions between co-infecting parasites include resource competition, direct competition and immune-mediated interactions and each are likely to alter the dynamics of single parasites. We posit that co-infection is a driver of variation in parasite establishment and growth, ultimately altering the production of parasite transm...
