ACQUISITION OF LACTOSE-FERMENTING PROPERTIES BY SALMONELLAE I

Acquisition of lactose-fermenting properties by salmonellae. I. Interrelationship between the fermentation of cellobiose and lactose.

The fermentation of lactose by salmonellae has seldom been accomplished, and in but few serological types (Kauffmann, 1954; Kristensen, 1948, 1955). In previous investigations we (Schafler and SchiLfler, 1959) succeeded in obtaining lactose-positive variants in 17 out of 30 salmonella strains belonging to different types, by means of 32 to 150 days of incubation on partially defined media conta...

Lactose-fermenting Salmonella.

Salmonella species are generally considered to be unable to ferment lactose and sucrose according to Bergey's Manual. Recently, however, J. M. Bulmash, McD. Fulton, and J. Jiron (J. Bacteriol. 89:259, 1965) and L. J. Kunz and W. H. Ewing (J. Bacteriol. 89:1629, 1965) have reported two separate species of Salmonella capable of fermenting lactose and sucrose. The organism reported here again illu...

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

Outbreak of food poisoning caused by lactose-fermenting Salmonella tuebingen.

An outbreak of food poisoning occurred in a cafeteria and involved 102 student nurses. A lactose-fermenting strain of Salmonella tuebingen was isolated. The source was traced to the chicken consumed. Production of H2S was not evident on triple sugar iron but was detected on lysine iron agar. Therefore, the present report emphasizes the importance of bismuth sulfite agar and lysine iron agar for...
