Morganella

Several taxa of Enterobacteriaceae inclnding Morganella morganii, Proteus vulgaris, and Raoultella (Klebsiella) planticola are able to decarboxylate the amino acid histidine, which is abundant in the mnscle tissne of scombroid hsh (Yoshinaga and Frank 1982 Takahashi et al. 2003). The histamine produced has been associated with an incident of scombroid fish poisoning (Taylor et al. 1989). 

Under conditions of oxygen limitation, strains of Morganella morganii and Providencia rettgeri degraded hexahydro-l,3,5-trinitro-l,3,5-triazine (RDX) after initial reduction to the nitroso compounds (Kitts et al. 1994).

Salt concentrations of up to 2% have been shown to be ineffective in preventing the growth of Morganella morganii and Klebsiella pneumonia. Higher concentrations of salt (3.5 to 5.5%) could inhibit the histamine production of some histamine-forming bacteria. In one study, the degree of inhibition of bacteria stored for five weeks at 5°C showed a linear relationship with the concentration of salt.
