MANUAL OF DETERMINATIVE BACTERIOLOGY 



4. Miyagawanella pneumoniae Rake, 

 spec. nov. Named for the disease, pneu- 

 monia. 



Coccoid bodies: As for Miyagawanella 

 lymphogranulomatis but slightlj' smaller, 

 circa 200 millimicrons in diameter. 



Cultivation : As for Miyagawanella 

 psittaci. 



Immunological aspects : As for Miya- 

 gawanella psittaci. Distinct from Miya- 

 gawanella ornithosis by the neutraliza- 

 tion test with chicken antisera. 



Pathogenicity: Pathogenic for birds, 

 man, cotton rats, hamsters, white rats, 

 kangaroo rats, mice and chicken embryos. 

 Causes a fatal pneumonitis in man. 



Tissue tropisms : As for Miyagawanella 

 ornithosis. 



Chemotherapy : As for Miyagawanella 

 ornithosis . 



Source : Occurs in lungs of infected hu- 

 mans. Possibly originally of avian origin. 



Habitat: The etiological agent of one 

 type of viral pneumonia. The type strain 

 is the so-called strain S-F (Eaton, Beck 

 and Pearson, Journ. Exp. Med., 73, 1941, 

 641). 



5. Miyagawanella bronchopneumoniae 

 Moshkovsky. (Aloshkovsky, Uspekhi 

 Souremennoi Biologii, 19, 1945, 19; Ehrli- 

 chia broncho pjieunwniae Moshkovsky, 

 idem.) Named for the disease, broncho- 

 pneumonia. 



Coccoid bodies: As for Miyagaivanella 

 pneumoniae. 



Cultivation: As for Miyagawanelki 

 lymphogranulomatis. Does not grow in 

 the allantoic cavity of the chick. 



Immunological aspects : As for Miya- 

 gawanella lymphogranulomatis but no 

 soluble antigen has been demonstrated. 



Toxic factor : Heavily infected 3'olk 

 sacs and yolk injected intravenously are 

 very rapidly fatal to mice. 



Pathogenicity : Pathogenic for mice, 

 hamsters and ferrets. Produces a mod- 

 erately severe pneumonitis. 



Tissue tropisms: Shows a predileclion 



for the lungs. In mice, it is also infec- 

 tive by the intravenous route. 



Chemotherapy : Susceptible to sulfon- 

 amides and to relatively large doses of 

 penicillin. 



Source : Found in lungs of certain 

 stocks of the laboratory mouse. 



Habitat : The agent of mouse pneumo- 

 nitis. Bronchopneumonie virus (Gon- 

 nert. Cent. f. Bakt., I Abt., Orig., H7 , 

 1941, 151). 



6. Miyagawanella felis Rake, spec. 

 nov. From Latin Jelis, cat. 



Coccoid bodies : As for Miyagawanella 

 lymphogranulomatis . 



Cultivation : As for Miyagawanella 

 psittaci . 



Immunological aspects : As for Miya- 

 gawanella psittaci but nothing known 

 about inapparent infections in the 

 natural host, the domestic cat. 



Toxic factor: Infected yolk sac or 

 other membranes and yolk or other fluids, 

 injected intravenously into mice or 

 chicken embryos or intraperitoneally 

 into mice are rapidly fatal. 



Pathogenicity : Pathogenic for cats, 

 hamsters, mice and chicken embryos. 

 Causes a fatal pneumonitis with acute 

 conjunctivitis in cats. 



Tissue tropisms : Prediliction for lungs 

 and conjunctivae. In laboratory ro- 

 dents, this species is infective by the 

 intranasal, intraperitoneal, intracerebral 

 and intravenous routes. 



Chemotherapy : As for Miyagaivanella 

 ornithosis. 



Source : Lungs of infected cats. 



Habitat : The etiological agent of one 

 form of cat nasal catarrh, influenza or 

 distemper (Baker, Science, 96, 1942, 475) 

 and feline pneumonitis. 



7. Miyagawanella louisianae Rake, 

 spec. nov. Named for the State of 

 Louisiana. 



Coccoid bodies : As for Miyagawanella 

 psittaci.
