INFLAMMATION AND SUPPURATION 



found in the muco-purulent secretion by staining films with 



_ weak (1 : 10) carbol- 



fuchsin, and is often to 



be seen in the interior

\ Another organism ex- 



^ ceedingly like the prev- 



ious, apparently differing 



JJJfZffZf from it only in the rather 



V M>* wider conditions of 



growth, is Muller's bacil- 

 lus. It has been culti- 

 vated by him in a con- 

 siderable proportion of 

 cases of trachoma, but

bacilli, chiefly contained within a leucocyte, lus which is now well 



(From a preparation by Dr. Inglis Pollock.) rec ognised is the diplo- 



bacillus of conjunctivitis 



first described by Morax. It is especially common in the more 



subacute cases of conjunctivitis. Eyre found it in 2 '5 per cent 



of all cases of conjunc- 



tivitis. Its cultural char- 



acters are given below. 



The xerosis bacillus, 



which is a small diph- 



theroid organism (Fig. 



123), has been found in 



xerosis of the conjunc- 



tiva, in follicular con- 



junctivitis, and in other 



conditions ; it appears 



to occur sometimes also 



in the normal conjunc- 



tiva. It is doubtful 



whether it has any 



pathogenic action of im- 



portance. Acute con- 



junctivitis IS also pro 



duced by the pneumo- 



coccus, epidemics of the 



disease being sometimes due to this organism, and also by
