BACTERIA IN DECOMPOSING SALMON 101 



the salmon as described in table 10. Cultures Ws and 374 are 

 also identical strains of Ps. fluorescens isolated from sea-water in 

 widely separated localities and from the various parts of decom- 

 posing salmon. As shown in table 1 this organism was obtained 

 from water 3 times and from salmon 12 times. Ps. fluorescens 

 was not found among the 94 cultures from Alaskan canneries. 



Cultures Wsd and 301 „ are yellow bacteria identical in their 

 morphology and cultural reactions. This organism was obtained 

 once from sea-water collected at Ilwaco, Wash., and three times 

 from salmon. Cultures Wea, 303 and 456 are also yellow pig- 

 ment producing bacteria with identical moiphology and cultural 

 reactions isolated once from sea-water, four times from salmon 

 and nine times from Alaskan canneries. References to table 10 

 and to the map (fig. 1) will show that this organism was found in 

 widely separated areas throughout Southeastern Alaska. A 

 third yellow organism, represented in the tables as 403 and 467, 

 was obtained once from salmon and once from a cannery at 

 IVIetlakatla. 



Cultures We, 390 and 417 were identified as a strain of Bad. 

 cloacae isolated once from water collected at Chinook, Wash., 

 seven times from salmon and once from a cannery at Haines, 

 Alaska (see map, fig. 1). Since 316b, 323, 380 and 419 each 

 represent an atypical strain of Bad. cloacae they have not been 

 considered as identical with We, 390 and 417. It is possible, 

 however, that the correlation might be extended to include the 

 sources from which the atypical strains of this organism were 

 isolated. 



Cultures Wtu, 406 and 454 are identical and this organism was 

 found twice in water from Alaska, twice from salmon and three 

 times from canneries in Ketchikan, Alaska. It will be noted 

 that Haines and Tee Harbor, Alaska, where this organism was 

 found in the water are a great distance from Ketchikan (fig. 1) 

 where it was found in the canneries. The fact that this organism 

 was also isolated from salmon in Oregon indicates that it is 

 widely distributed. 



Cultures Wrb and 430 are bacteria having thes ame moiphology 

 and cultural reaction, isolated once from the water at Haines,
