With the object of perfecting the knowledge of infectious diseases in the tropics and to give to tropical medicine the scientific basis now held by the most advanced nations, this conference requests of the Governments of the American Republics that wherever these elements of progress are lacking they encourage every project tending to provide special information on parasitology and on pathological anatomy.
CSP4.R13 - XIII. To request also of the Governments of the American Republics that they favor the establishment in seaports and important cities of laboratories where not only diagnoses may be made in order to comply with the requirements contained in the resolutions of our sanitary conventions, but where also original investigations in tropical medicine and general pathology can be made along lines which the sanitary authorities deem practicable.
