Immunogenicity of a reduced-dose whole killed rabies vaccine is significantly enhanced by ISCOMATRIX™ adjuvant, Merck amorphous aluminum hydroxylphosphate sulfate (MAA) or a synthetic TLR9 agonist in rhesus macaques.

There is a need for novel rabies vaccines suitable for short course, pre- and post-exposure prophylactic regimens which require reduced doses of antigen to address the current worldwide supply issue. We evaluated in rhesus macaques the immunogenicity of a quarter-dose of a standard rabies vaccine formulated with Merck's amorphous aluminum hydroxylphosphate sulfate adjuvant, the saponin-based ISCOMATRIX™ adjuvant, or a synthetic TLR9 agonist. All adjuvants significantly increased the magnitude and durability of the humoral immune response as measured by rapid fluorescent focus inhibition test (RFFIT).

Plasmodium Falciparum malaria and perinatally acquired human immunodeficiency virus type 1 infection in Kinshasa, Zaire. A prospective, longitudinal cohort study of 587 children.

Background: It is uncertain whether Plasmodium falciparum malaria is more frequent or more severe in children with perinatally acquired human immunodeficiency virus type 1 (HIV-1) infection and whether P. falciparum infection accelerates the progression of HIV-related disease.

Methods: We conducted a prospective, longitudinal cohort study in Kinshasa, Zaire.

[Anomalies of enamel structure: description of a clinical case].

The anomalies of dental structure are quite common in pediatric dentistry; these anomalies can involve separately or in the same time enamel, dentin or cementum and they are due to many factors acting during odontogenesis and istogenesis. The Authors analyse these abnormalities and describe a personal case.
