Coles, the first to study these organisms; M.L. fem.n. Colettsia an arbitrarily formed generic name. Large, pleomorphic cells occurring intracytoplasmically. Apparently non-pathogenic, but may be saprophj^tic. Found only in the conjunctival cells of goats, sheep and cattle. The type species is Colettsia pecoris Rake. 1.

Cultivable in chicken embryonic tissues in tissue culture. Susceptible to sulfonamides and antibiotics. Pathogenic, causing various diseases in warm-blooded animals.

The etiological agent of psittacosis (parrot fever). 2. Miyagawanella psittaci. III. The etiological agent of ornithosis (Meyer). 3. Miyagawanella ornithosis. IV. The etiological agent of one type of viral pneumonia. 4. Miyagawanella pneumoniae.
