FURTHER STUDIES ON AEROMONAS. I. ADDITIONAL STRAINS AND SUPPLEMENTARY BIOCHEMICAL TESTS

Abstract

Summary The results are given of the behaviour of 88 strains of Aeromonas in an extended series of biochemical tests. Additional tests confirm the view that Aer. formicans merits specific rank. It is proposed that Aer. liquefaciens be renamed Aer. punctata and that Aer. formicans be renamed Aer. caviae.

The Classification of 'Bacterium salmonicida'

“…Since its systematic position is in doubt, the former name will be used here, though it is an illegitimate name. Recently, however, some workers, including Griffin, Snieszko & Friddle (1953a), Eddy (1960Eddy ( , 1962, Ewing, Hugh & Johnson (1961), and Schubert (1961), have classified the organism as one of the genus Aeromonas. The strains of this organism isolated at the Marine Laboratory, Aberdeen, did not fall into the genus Aeromonas when classified according to Skerman (1957) because of weak gas production from glucose.…”

Extracellular proteolytic activity of Aeromonas hydrophila complex.

“…Most investigators who studied this proteolytic activity have used gelatin liquefaction, and/or casein or milk diges tion as an index of activity (DE FIGUEIREDO and PLUMB, 1977;EDDY, 1960;KOU, 1972;MCCARTHY, 1975;NORD et al, 1975;PAVLOVSKIS and WRETLIND, 1979;VON RIESEN, 1975). Some researchers have included elastin hydrolysis (EDDY, 1962;NORD et al, 1975;POPOFF and VERON, 1976;SCHARMANN, 1972). However, few studies have been done which include albumin, fibrin or col lagen hydrolysis (CASELITZ and KREBS, 1961;EDDY, 1962;SCHARMANN, 1972).…”

However, few studies have been done which include albumin, fibrin or col lagen hydrolysis (CASELITZ and KREBS, 1961;EDDY, 1962;SCHARMANN, 1972). To date, the lack of standardized agar plate media with suffi cient sensitivity has hampered investigation of these proteolytic characteristics, especially elastin hydrolysis.…”
