132 A MANUAL OF BACTERIOLOGY 



to Dr. Burger, 1 oval micrococci are often present 

 in the pearly phlegm ejected by patients suffering 

 from this disease. They have not yet been culti- 

 vated. 



Micrococcus in pernicious anaemia. According to 

 Frankenhauser 2 the blood of pregnant women suffer- 

 ing from pernicious anaemia contains a large number 

 of micrococci which appear to be of a pathogenic 

 character. These micrococci are comparatively of 

 large size, ' about one-tenth of the broad diameter 

 of a red blood-corpuscle.' These microbes have not 

 been cultivated. 



Micrococcus of Nitric Fermentation. Mr. E. War- 

 ington, F.K.S., 3 has recently isolated from soil a 

 micrococcus which converts nitrites into nitrates. 

 But this micrococcus, as well as Frankland's nitrous 

 bacillus, will be described later, i.e. under the head- 

 ing of ' the microbes of the soil.' 



Micrococci in Pyaemia and Septicaemia. A con- 

 siderable number of micrococci (from O'l to I'O //, in 

 diameter) have been found in various organs, blood, 

 etc., in pyaemia and septicaemia in the lower animals 

 and in man. 4 



Micrococci have also been described in haemo- 

 philia neonatorium, in ozsena, in acute yellow 

 atrophy of the liver, in closed abscesses, and in many 

 other diseased conditions.
