[Various aspects of the influence of infection on growth and development].

It is pointed out how infections can delay growth and development through an aggressive and long-standing action, through direct action of an infecting agent (virus, bacteria, parasites). or through sequelae in main organs (brain, kidney, growth cartilage, muscular system, etc.).

[Counterimmunoelectrophoresis in the diagnosis of Bordetella pertussis].

The serum of 50 patients between 25 days to 15 years old who were admitted with the diagnosis of pertussis syndrome were investigated for precipitating antibodies by means of discontinuous counterimmunolectrophoresis (CIED). The presence of antibodies for Bordetella pertussis antigen was shown in 28 cases. All samples were taken within the first 24/48 hours of admission and at convalescence.
