678 INDEX OF INFECTIOUS DISEASES. 
the valves, when their introduction then increases and maintains the 
inflammatory process. 
Endometritis. The healthy uterine mucous membrane is usually 
sterile, but various species of bacteria have been observed in the 
secretions of the cervix uteri. In inflammations of the uterus not 
following abortion or child-birth the gonococcus is by far the most 
frequent micro-organism found. In inflammation following child- 
birth and operations the ordinary pus cocci and the colon bacillus 
are also frequently met with, as well as other varieties of bacteria. 
Erysipelas. Due to infection by streptococcus, 483. 
Fowl-cholera. Due to infection by bacillus cholere gallinarum 
(Fligge), probably identical with the bacillus of rabbit septicemia 
of Koch. 
Furunculosis. Due to infection by the different pus cocci, and 
more especially to the staphylococcus pyogenes aureus. 
Gangrene. Etiology not positively known, but probably due to 
. the invasion of various parasitic and saprophytic bacteria into the 
tissues when their vital resistance has become lowered by malnu- 
trition and pressure or by a poor blood-supply. 
Gas-formation. The bacillus aérogenes capsulatus, 545, has 
been found either alone or along with pyogenic bacteria. 
Glanders or Farcy. Due to infection by bacillus mallei, 600, 
602. 
Gonorrhea. Due to ‘‘gonococcus,” 528 (Neisser). 
Hog-cholera. Due to infection by bacillus of hog-cholera (Sal 
mon and Smith). 
Hog -erysipelas or Swine-plague. Due to infection by bacillus 
of swine-plague (Salmon and Smith), 
Hydrophobia. No micro-organism has as yet been discovered 
which is specific for this disease, 660. 
Influenza. La Grippe. Due to infection by the bacillus of 
influenza, 324. Pneumococcus inflammations often show similar 
symptoms. 
Influenza of Horses. Various micro-organisms, some resem- 
bling the pneumococcus and others the streptococcus in man, have 
been described and claimed to be the specific cause of this epidemic 
disease in horses. 
Keratitis. According to Bach (1895) purulent keratitis is due 
to the invasion of the cornea by micro-organisms, the pyogenic cocci, 
pneumococci, etc., secondary to traumatism. 
Leprosy. Due to the bacillus leprae, 316
