Bemarks. — De Mello and his colleagues (1917) found 

 Anaplasmosis in the blood of fishes, frogs, lizards, snakes, 

 tortoises, and man. Discussing the origin of the so-caUed 

 Anaplasma, they came to the conclusion that they are not 

 Protozoa, but are unquestionably due to hsemolytic altera- 

 tions. They regarded them as due to nuclear fragmentation,.

which is normal in Vertebrates with nucleated red corpuscles, 

 or pathological, as in anaemias of Mammals.

Bertarellia, Carini, 1930, pp. 1312-13 ; de Mello & de Meyrelles, 

 1937 b, pp. 98-108. 



Polymorphic intra-corpuscular bodies, probably of a para- 

 sitic nature ; usually round or oval, variable in size, smallest 

 of the size of cocci and the largest 1-2 ^u, in diameter. Stained 

 with Leishman's or Giemsa's stains, in the largest individuals 

 the cytoplasm is stained blue, usually with a chromatic granule 

 stained red. The infected red blood- corpuscles are not altered.

■fBertarellia calotis, de Mello & de Meyrelles, 1937 b, pp. 98-108, 

 pi. xii, 2 text-figs. 



Circular bodies, with refringent greenish cytoplasm 

 surrounded by a strong membrane, intra-corpuscular or free, 

 dividing by a process of budding. Stained by Leishman's 

 or Giemsa's stains they show a variety of forms ; they appear 

 either as a small round chromatic dot, of anaplasmoid nature.
