Yersinia enterocolitica was recovered from well water during a large water-borne outbreak of gastrointestinal illness. Isolates were predominantly Nilehn biotype 1, of which 57% were serologically nontypable. Isolation and enumeration of these Y. enterocolitica strains were made on M-Endo broth. Laboratory studies were conducted on selected isolates to establish the growth of Y. enterocolitica ...

The research on ciliates, flagelates and opalinates have been widespread by the utilization of techniques employing silver impregnation (protargol), modified by several authors. However, these are time consuming and its results are variable. The present work is a variant of the technique described by Tuffrau (1964, 1967) showing some adaptations made in our laboratory. The organisms can be pres...

ion Ezchunye Resins-De-Acidite (The Permutit Company, New York), washed on a 40 mesh screen with distilled water, was treated several times with aqueous 4 per cent sodium carbonate and repeatedly washed with distilled water, by suspension and decantation, until the supernatant liquid was colorless and had a pH of 8.0 or less. The resin collected on a suction filter contained 70 to 80 per cent w...

Heat dissipation from electrical appliances is a significant issue with contemporary electrical devices. One factor in the improvement of heat dissipation is the heat transfer performance of the working fluid. In this study, we used plasma arc technology to produce a nanofluid of carbon nanoparticles dispersed in distilled water. In a one-step synthesis, carbon was simultaneously heated and vap...

L( + )-Arginine hydrochloride was obtained from the Sigma Chemical Co., St Louis, Mo., U.S.A. The Arlco jackbean meal used in the preparation of urease was supplied by Hopkin and Williams Ltd., Chadwell Heath, Essex. The 'manganese-maleate solution' used in the preparation of arginase was made by dissolving 8-9 g. of MnSO4,4H20 and 1-8 g. of disodium maleate in glassdistilled water and making t...

The chemical composition and functional activities of cold-pressed and water distilled peel essential oils of Citrus paradisi (C. paradisi) and Citrus grandis (L.) Osbeck (C. grandis) were investigated in present study. Yields of cold-pressed oils were much higher than those of distilled oils. Limonene was the primary ingredient of essential oils of C. paradisi (cold 92.83%; distilled 96.06%) a...

Washed vegetative cells of Bacillus mycoides obtained and treated under specified conditions have been found to sporulate when shaken in distilled water under specified conditions. Within limitations of the methods, a heat-resistant cell (spore) is produced for each heat-sensitive vegetative cell present initially. Several different experiments designed to detect massive lysis and cell growth d...

Distilled water suspensions of Legionella pneumophila were found to be sensitive to low doses of germicidal ultraviolet radiation.

During the recent severe cholera epidemic (June to September 1945) in a group of villages in the Central Provinces I, as medical officer-in-charge of the Mundi Hospital, had occasion to treat ninety-five cases by saline transfusion with a mortality of only four persons. Of these four deaths, one was due, in my opinion, to my not being able to give a second transfusion owing to the distance and ...
