The customary methods of evaluation of chemical disinfectants concern the question of the germicidal performance under specified conditions of these products compared with that of a reference material. As a rule, the fundamental answer is sought to this query: When used in the recommended dilution, will a given disinfectant kill the test-organism wvithin the specified short period of time? From...

background: acinetobacter baumannii plays an important role in some types of nosocomial infections as an opportunist microorganism which increases levels of resistance to antibacterial drugs and disinfectants. objectives: the aim of this study was to determine the resistance and sensitivity of a. baumannii to different antibiotics and evaluate the minimal inhibitory concentration (mic) for cipr...

or uncombined, is beneficial in cholera. In the case under notice the black oxide of manganese was not used, therefore the gas obtained, I should have mentioned, was hydrochloric acid and not chlorine. Had black oxide of manganese been available at the time, it would have been employed, for the element in an uncombined form would be more potent than in a combined form. The carbonate of soda was...
