| [antibacterial activity of a lysozyme-like enzyme from staphylococci]. | a lysozyme-like enzyme isolated from the culture broth of staph. aureus 712 presented in its native state a lipoproteid complex. the lytic and antibacterial spectrum of the enzyme was similar to that of the egg albumin enzyme. however, the lipoproteid complex was somewhat superior to the egg albumin complex in its activity against micrococcus lysodeikticus, a number of gramnegative bacteria and staphylococci. out of the organisms studied microccus lysodeikticus, sarcina and bac. subtilis proved ... | 1975 | 813563 |
| fluid and electrolyte transport in rhesus monkeys challenged intracecally with shigella flexneri 2a. | shigella flexneri 2a is an invasive enteric pathogen that may produce diarrhea when ingested by human beings and subhuman primates. we have previously shown that shigella diarrhea correlates with water and electrolyte transport abnormalities in the jejunum and colon. dysentery alone is associated only with colonic transport abnormalities. to define the relationship between invasion and inflammation of the colon and the occurrence of jejunal transport abnormalities, we studied water and electroly ... | 1976 | 823110 |

| irradiation of cells by single and double pulses of high intensity radiation: oxygen sensitization and diffusion kinetics. | the biological effects of ionizing radiation in living cells are the ultimate result of a long chain of events with the initial step being the local absorption of radiation. whereas such physical abosrption is probably over within 10(-16) s after dose delivery, the biological consequences of radiation do not manifest themselves until very much later times. between these two extremes of time, events occur relatively early at the molecular level which are undoubtedly critically related to the stil ... | 1976 | 826371 |
| recurrent urinary tract infection due to shigella flexneri--case report. | a case of urinary tract infection due to shigella flexneri is reported. the case presented suggests that in persistent and recurrent urinary tract infection in topical countries, investigations for organisms such as shigella flexneri should be considered. urinary tract infection due to shigella flexneri is unknown and as far as we known has not been reported in the literature. a case report is presented in whom recurrent urinary tract infection was due to shigella flexneri and was treated effect ... | 1976 | 826670 |
| [use of the neutralization test for mass population studies]. | the authors applied the antibody neutralization test (ant) for detection of causative agent of intestinal infections in feces of healthy population in turkmenia. some part of the material was studied in parallel with the aid of the ant and by the bacteriological method. as a result of comparison it appeared that in using the ant causative agents of intestinal infections were revealed much more frequently than by the bacteriological method; in this connection this serological method can be recomm ... | 1976 | 828825 |
| in vitro activity of cinoxacin, ampicillin, and chloramphenicol against shigella and nontyphoid salmonella. | the in vitro antibacterial activity of cinoxacin was compared with that of ampicillin and chloramphenicol against 26 strains of nontyphoid salmonella and 44 strains of shigella. cinoxacin was found to have a lower minimal inhibitory concentration than ampicillin and chloramphenicol against all salmonella and shigella sonnei strains. cinoxacin had minimal inhibitory concentrations similar to those of chloramphenicol but lower than those of ampicillin against shigella flexneri and s. boydii strain ... | 1977 | 856008 |
