Care of dying patients.

This article provides an overview of the care required by patients in the last 48-72 hours of life, as well as the support required by carers.

Differentiation of Aerobacter-Klebsiella isolated from sugarcane.

Three hundred and eighty-four isolates were obtained in the completed test portion of the most probable number determinations of coliforms in sugarcane sources. Of these isolates, 88% were of the (- - + +) indole, methyl red, Voges-Proskauer, citrate (IMViC) type and were identified as Aerobacter aerogenes according to the protocol of the American Public Health Association (1). Employing 359 of these cultures, a comparative biochemical, serological, and pathogenicity study was carried out with Klebsiella pneumoniae CDC no.

Effect of herbicides on cellulose decomposition by Sporocytophaga myxococcoides.

The effects of 14 herbicides on cellulose decomposition by Sporocytophaga myxococcoides were studied by growing the organism in two different liquid cellulose-mineral salts media in the presence of the test agent and then quantitatively determining the residual cellulose. In the first medium, containing acid-hydrolyzed cellulose, anthrone reagent was used to determine residual carbohydrate. In the second medium, Gooch Pyrex fritted-glass crucibles were used to determine the amount of residual Whatman powdered cellulose.

COLIFORMS ASSOCIATED WITH SUGARCANE PLANTS AND JUICES.

A study of the coliforms found on sugarcane plants throughout the growing season indicated that members of the genus Aerobacter comprise a part of the epiphytic microflora. When quantitative determinations were made of the coliforms by means of the most probable number technique, no completed tests were obtained on young sugarcane plants during the test period of February through May; however, Paracolobactrum aerogenoides was isolated frequently. Nine different IMViC types of coliforms were identified among the 198 isolates chosen for study.

The effect of 2,3,6-trichlorophenylacetic and 2,2-dichloropropionic acids on nitrite oxidation.

The effects of two herbicides, 2,3,6-trichlorophenylacetic acid, sodium salt, and 2,2-dichloropropionic acid, sodium salt, on nitrite-oxidizing bacteria were studied by the soil perfusion technique. The time of application of 2,3,6-trichlorophenylacetic acid affected its toxicity to the nitrifier. When it was present in the environment as the nitrifier started growth, it was more toxic than if the organisms were allowed to nitrify actively before they were subjected to the herbicide.
