Immunoprotectivity of Salmonella enterica serovar Enteritidis virulence protein, InvH, against Salmonella typhi
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...
متن کاملMolecular characterization of the Salmonella enterica serovar Typhi Vi-typing bacteriophage E1.
Some bacteriophages target potentially pathogenic bacteria by exploiting surface-associated virulence factors as receptors. For example, phage have been identified that exhibit specificity for Vi capsule producing Salmonella enterica serovar Typhi. Here we have characterized the Vi-associated E1-typing bacteriophage using a number of molecular approaches. The absolute requirement for Vi capsule...
متن کاملGenotyping of Salmonella enterica serovar Typhi strains
Results Forty representative S. Typhi strains belonged to 4 sequence types (ST1, ST2, ST890, and ST892). The predominant S. Typhi genotype (31/40) was ST2 and it had a diverse geographic distribution. We discovered two novel STs – ST890 and ST892. M-CGH showed that 69 genes in these two novel STs were divergent from S. Typhi Ty2, which belongs to ST1. In addition, 5 representative Typhi strains...
متن کاملThe genome of Salmonella enterica serovar Typhi.
The generation of complete genome sequences provides a blueprint that facilitates the genetic characterization of pathogens and their hosts. The genome of Salmonella enterica serovar Typhi (S. Typhi) harbors ~5 million base pairs encoding some 4000 genes, of which >200 are functionally inactive. Comparison of S. Typhi isolates from around the world indicates that they are highly related (clonal...
متن کاملMultidrug resistant Salmonella enterica serovar typhi.
Nepal is having a series of enteric fever epidemics over the last decade1,2 with changing resistance patterns.3 The fi rst report of multidrug resistant Salmonella enterica serovar Typhi in Nepal was published in 1991.4 In the following years, with the introduction of fl uoroquinolones in the treatment, nalidixic acid-resistant strains associated with reduced susceptibility to fl oroquinolones ...
