MANUAL OF DETERMINATIVE BACTERIOLOGY 



Thermal inactivation : At 56° C in 30 

 minutes. 



Literature : Kuttner and Wang, Jour. 

 Exp. Med., 60, 1934, 773-791. 



4. Rabula exiguus spec. nor. From 

 Latin exiguus, petty. 



Common name : Rat salivary -gland 

 virus. 



Host : M URIDAE— rat. 



Insusceptible species: M URIDAE — 

 Mus musculus L., mouse. CRICETI- 

 DAE — Cricetulus griseus M. Edvv., Chi- 

 nese hamster. 



Geographical distribution : China, 

 Canada. 



Induced disease : In rat, no obvious 

 disease externally, but intranuclear in- 

 clusions in cells of the submaxillary 

 glands. 



Literature : Kuttner and Wang, Jour. 

 Exp. Med., 60, 1934, 773-791 ; Thompson, 

 Jour. Inf. Dis., 50, 1932, 162-170. 



5. Rabula latens spec. nov. From 

 Latin latens, hidden or lurking. 



Common name : Mouse salivary -gland 

 virus. 



Host: M URIDAE — Mus muscvlus L., 

 mouse. 



Insusceptible species: MURIDAE — 

 rat. CRICET I DAE— Cricetulus griseus 

 M. Edw., Chinese hamster. LEPOR- 

 I DAE— rahhii. CA VIIDAE—Cavia 

 porcellus (L.), guinea pig. 



Geographical distribution : China, 

 Canada, United States. 



Induced disease : In mouse, no obvious 

 disease externally, but inclusion bodies 

 in acinar tissue of serous and mucous por- 

 tions of submaxillary glands ; occasionally 

 also in duct cells or alveolar cells of paro- 

 tid gland; affected cells hypertrophied. 

 In Swiss white mice, extensive lesions in 

 liver and spleen but emulsions of these 

 organs fail to infect; rare pancreatic 

 lesions. 



Transmission : Experimentally, by in- 

 traglandular, subcutaneous, intraperi- 

 toneal, intra testicular or intracerebral 

 inoculation; inclusion bodies appear in 

 salivary glands irrespective of site of 

 inoculation. 



Thermal inactivation : At 60° C in 30 

 minutes. 



Filterability : Passes Berkefeld V filter 

 candle.
