Mu-Like Prophage in Serogroup B Neisseria meningitidis Coding for Surface-Exposed Antigens

Masignani, Vega, Giuliani, Marzia Monica, Tettelin, Hervé, Comanducci, Maurizio, Rappuoli, Rino, Scarlato, Vincenzo

Sequence analysis of the genome of Neisseria meningititdis serogroup B revealed the presence of an ∼35-kb region inserted within a putative gene coding for an ABC-type transporter. The region...

The Region Comprising Amino Acids 100 to 255 of Neisseria meningitidis Lipoprotein GNA 1870 Elicits Bactericidal Antibodies

Giuliani, Marzia Monica, Santini, Laura, Brunelli, Brunella, Biolchi, Alessia, Aricò, Beatrice, Di Marcello, Federica, ...

GNA 1870 is a novel surface-exposed lipoprotein, identified by genome analysis of Neisseria meningitidis strain MC58, which induces bactericidal antibodies. Three sequence variants of the protein...

Genome analysis of multiple pathogenic isolates of Streptococcus agalactiae: Implications for the microbial “pan-genome”

Tettelin, Hervé, Masignani, Vega, Cieslewicz, Michael J., Donati, Claudio, Medini, Duccio, Ward, Naomi L., ...

The development of efficient and inexpensive genome sequencing methods has revolutionized the study of human bacterial pathogens and improved vaccine design. Unfortunately, the sequence of a single...

Identification of a Universal Group B Streptococcus Vaccine by Multiple Genome Screen

Maione, Domenico, Margarit, Immaculada, Rinaudo, Cira D., Masignani, Vega, Mora, Marirosa, Scarselli, Maria, ...

Group B Streptococcus (GBS) is a multiserotype bacterial pathogen representing a major cause of life-threatening infections in newborns. To develop a broadly protective vaccine, we analyzed the...

Streptococcus pneumoniae Pilus Subunits Protect Mice against Lethal Challenge▿

Gianfaldoni, Claudia, Censini, Stefano, Hilleringmann, Markus, Moschioni, Monica, Facciotti, Claudia, Pansegrau, Werner, ...

Streptococcus pneumoniae is a major public health threat worldwide. The recent discovery that this pathogen possesses pili led us to investigate their protective abilities in a mouse model of...

A universal vaccine for serogroup B meningococcus

Giuliani, Marzia M., Adu-Bobie, Jeannette, Comanducci, Maurizio, Aricò, Beatrice, Savino, Silvana, Santini, Laura, ...

Meningitis and sepsis caused by serogroup B meningococcus are two severe diseases that still cause significant mortality. To date there is no universal vaccine that prevents these diseases. In this...

Pneumococcal Pili Are Composed of Protofilaments Exposing Adhesive Clusters of Rrg A

Hilleringmann, Markus, Giusti, Fabiola, Baudner, Barbara C., Masignani, Vega, Covacci, Antonello, Rappuoli, Rino, ...

Pili have been identified on the cell surface of Streptococcus pneumoniae, a major cause of morbidity and mortality worldwide. In contrast to Gram-negative bacteria, little is known about the...

Vaccination against Neisseria meningitidis Using Three Variants of the Lipoprotein GNA1870
