SECTION 7. EAEEE POEMS OF CONJUNCTIVITIS. 



1. Conjunctivitis due to the Bacterium Coli. 



PLATE I., FIG. V. 



In 1896 Axenfeld found the Bacterium coli in pure culture in a case 

 of ophthalmia neonatorum ; since then Bietti, Zur Nedden, Saemisch, 

 and McKee have also found it. In their series of cases of catarrh in 

 the new-born infant Groenouw and Cramer found, along with the 

 Gonococcus, Bacteria which belonged to the coli group, but in some 

 particulars differed from the ordinary form of coli. Axenfeld and 

 Bietti state that blennorrhoaa from this cause heals more rapidly 

 than the gono-blennorrhoea (of Saemisch) does. The bacilli when 

 tested on animals were very pathogenic. Jarnatowski reported a case 

 of conjunctivitis with the Bacterium coli in an adult. Vossius and 

 Markwaldt found bacilli of the coli group in a case of double con- 

 junctivitis with iridocyclitis occurring in dysentery. 



U. Tailor reported a case of peculiar necrotic diphtheritic inflamma- 

 tion in a child of one and a half years. It resembled a lime burn in 

 appearance, and in the discharge bacilli of the coli group were found, 

 which, when tested on animals, did not produce suppuration but 

 necrosis. 



We have no definite records of inoculation of human beings with 

 the Bacterium coli. As, however, the Bacterium coli can cause a catarrh 

 in other mucous membranes, especially the bladder, an etiological 

 role can be attributed to it in those cases where it is found in the con- 

 junctival sac in large numbers and in pure culture. Infectiousness 

 has not yet been observed. Its power of causing inflammation 

 and suppuration is apparent from the experiments of Panas and 

 Picot. 



The Bacterium coli has been found a few times in the pus of a 

 dacryocystitis* (Mircoli, Uhthoff, Mazet), once in a panophthalmitis 

 (Randolph), once in pus from the orbit (Loser), and a few times 

 in hypopyon-keratitis (Zur Nedden, de Berardinis, Bietti).
