BACTERIA IN DECOMPOSING SALMON 105 



Alaska, and eight times from canneries in Alaska extending from 

 Excursion Inlet on the north to Metlakatla on the south. This 

 culture was not found in decomposing salmon. 



As seen in the tables, cultures Wtc, 399 and 473 are identical 

 in morphology and cultural reactions. This organism was 

 isolated once from sea-water collected at Haines, Alaska, once 

 from salmon and twice from canneries at Yes Bay and Ketchikan, 

 Alaska. 



Cultures Wsa, 360 and 421 were identified as a flesh-colored 

 organism isolated once from sea-water collected at Ilwaco, 

 Wash., eleven times from salmon and once from a cannery at 

 Tee Harbor, Alaska. 



The culture of Bad. aeroqenes isolated twice from sea-water 

 from Alaska, once from sahnon and three tinaes from canneries 

 at Haines and Tee Harbor, Alaska, is designated in the tables 

 under ^^'l2, H; and 424. 



Cultures Wi2a, 314„ and 458 are identical. This organism was 

 isolated once from sea-water from Funter Bay, Alaska, three 

 times from sahnon and twice from canneries at Ketchikan and 

 Hawk Inlet. The isolation of this culture from material collected 

 from such widely separated areas indicates that it is generally 

 distributed throughout the whole region. 



Only two spore-forming bacteria were found in the course of 

 the work and one of these, represented in the tables as Wu and 

 397 was isolated three times from sea-water collected at Ilwaco, 

 Wash., Haines, Alaska, and Lynn Canal, Alaska. It was also 

 isolated once from decomposing salmon. Although this organism 

 appears to be widely distributed in the sea-water of that region 

 it was not common in the decomposing salmon and was not 

 found at all in the various parts of the canneries. When grown 

 in pure culture this spore-former seems to have no effect on fish. 



Cultures I and 420e are orange-colored organisms identical 

 in morphology and cultural reactions isolated once from salmon 

 and once from a cannery at Haines. It was not found in the 

 water samples examined. .\n orange-colored organism, repre- 

 sented by 401 and 443, was isolated once from salmon and twice 

 from canneries at Sitka and Chatham, Alaska.
