We present the derivation of the macroscopic equations for systems with an axial dynamic preferred direction. In addition to the usual hydrodynamic variables, we introduce the time derivative of the local preferred direction as a new variable and discuss its macroscopic consequences including new cross-coupling terms. Such an approach is expected to be useful for a number of systems for which o...
A variety of bacteria have been used as agents and vectors for antineoplastic therapy. A series of mechanisms, including native bacterial toxicity, sensitization of the immune system and competition for nutrients, may contribute to antitumor effects. However, the antitumor effects of Proteus species have been minimally studied, and it is not clear if bacteria can alter tumor hypoxia as a compon...
The present study aimed at analyzing the antibacterial efficacy of Mirabilis jalapa against different enteric bacteria includes Escherichia coli, Proteus mirabilis, Salmonella typhi, Shigella flexineri and Enterobacter aerogenes. Aqueous, Ethanolic, and hexane extracts of Mirabilis jalapa at the concentrations of 100, 200, 300, 400 and 500 mg were prepared for this study. The antioxidant proper...
N-nitrosodimethylamine, a potent carcinogen, was produced by three strains each of Proteus mirabilis, P. morganii, and P. rettgeri, but not by three strains of P. vulgaris grown under the same conditions. Many of the alkaline-extractable volatile metabolites elaborated by these organisms are the same, but there are some qualitative and quantitative differences among species. Representative gas-...
Quantitative urine culture by the dipinoculum technique of Mackey and Sandys (1965) has shown that the pattern of infection in male children is quite different from that of female children. Among boys under the age of 14 Proteus mirabilis is the causative organism in about 75% of cases of active urinary infection. By contrast only 15% of infection in girls is due to Proteus, the dominant pathog...
Thirteen indole-producing, swarming strains of Proteus were identified by additional biochemical testing as being Proteus mirabilis. These strains were characterized by 40 biochemical tests and by susceptibility testing to 11 antibiotics. All produced ornithine decarboxylase and were susceptible to members of the penicillin-cephalosporin groups of antibiotics. These indole-positive strains are ...

Proteus mirabilis, Proteus vulgaris, Morganella morganii, Providencia rettgeri, and Providencia alcalifaciens, which were once classified into the same genus, Proteus, were studied. Cefoxitin-resistant mutants from these species were isolated, and it was confirmed that the resistance was attributed to the lack of an outer membrane protein, resulting in a significant decrease in the penetration ...
