Ação do oxigenio sob pressão sobre a ação patogenica dos germens anaerobios

1) O² under pressure reduces the infectiosity of anaerobic bacteria. 2) This action of O² is increased with the lengthening of the time of exposure of the bacterial suspensions to the gas. 30 The reduction in infectivity is due to the death of the greater part of the bacteria submitted to the action of the O².

A soro-aglutinação das Leishmanias

The first agglutination experiments (Tables 1 and 2) showed that the serum obtained with any one strain of Leishmania, agglutinates all the others even of another species. This finding reveals the existence of a common antigen. However as the titre of agglutination did not permit a sharp differentiation of species we tried the adsorption method. The first adsorption tests made...
