infective

Abscess in the spleen occasionally occurs, usually in association with infective endocarditis or with general pyaemia.

There are other infective diseases, in which we have not yet found the causative micro-organism, but we presume its existence.

Diphtheria is perhaps the most obscure and complex of all the infective diseases in its causes and favouring conditions.

Infective conditions due to pyogenic infection (œsophagitis and peri-œsophagitis) are rare.
