    Notes: [Auszug] Samples of pigeon manure from the concrete floors, walls and window-ledges of buildings inhabited by pigeons, and of soil from localities frequented by pigeons, were collected from four areas in west-central and one area in south-west London. These were examined for the presence of C. neoformans by ...

    Notes: Abstract The efficacy of paraffin bait technique in the isolation ofNocardia asteroides from clinical specimens has been investigated. In a comparative study 1091 clinical specimens, mostly sputa and bronchial aspirates collected from 639 patients of bronchopulmonary diseases and 11 of meningitis, were examined by paraffin baiting and the conventional technique. Thirty-six clinical specimens originating from 12 of the patients yieldedN. asteroides by the paraffin bait technique but only 4 by the conventional technique. Approximately 95 % of 125 sputum samples inoculated withN. asteroides yielded the pathogen by paraffin baiting as against 49 % by the conventional technique. Paraffin baiting was more productive than the conventional technique in the isolation ofN. asteroides from mixed suspensions with a number of fungi and bacteria. It is concluded that paraffin baiting can be profitably adopted as a suitable technique for the isolation ofN. asteroides from clinical specimens, such as, sputum, gastric lavage, etc., which are often contaminated. The technique has no particular advantage with non-contaminated specimens.

    Notes: Abstract Normal vibration analysis of the mono-, di-, tri- and tetra-glycines has been carried out employing the Urey-Bradley force field. The results show that the oligomers possess the planar zig-zag structure of polyglycine-I in the solid state.

    Description / Table of Contents: Zusammenfassung Die Zusammensetzung von Donator-Akzeptor-Komplexen von Harnstoff und Thioharnstoff mit einigen aromatischen Kohlenwasserstoffen, nämlich Naphthalin, Anthracen, Phenanthren und Biphenyl, wurde durch Phasendiagrammuntersuchungen ermittelt. Schmelzenthalpie und -entropie dieser Komplexe wurden mittels DSC bestimmt. Es wurde festgestellt, daß die relative Stabilität der festen Donator-Akzeptor-Komplexe nicht aus der Fläche unter der Kurve im Phasendiagramm der kongruenten Verbindungen vorausgesagt werden kann.

    Notes: Abstract The compositions of charge-transfer complexes of urea and thiourea with some aromatic hydrocarbons (naphthalene, anthracene, phenanthrene and biphenyl) have been established through phase diagram studies. The enthalpies and entropies of fusion of these complexes have been estimated by differential scanning calorimetry. It is observed that the relative stabilities of the solid-state charge-transfer complexes in the donor-acceptor systems studied cannot be predicted from the areas under the curves of the congruent compounds in the phase diagrams.

    Notes: Abstract Medically important thermophilic actinomycetes were isolated from 218 (64%) of 341 samples of vegetable substrates and soil examined from sites in north-western India. Thermoactinomyces vulgaris (T. candidus) was the commonest species, occurring in 56% of samples, followed by Saccharomonospora viridis in 29%, Thermoactinomyces thalpophilus in 27%, Faenia rectivirgula (Micropolyspora faeni) in 21% and Thermoactinomyces sacchari in 14%. T. vulgaris and T. thalpophilus were isolated from all types of substrate examined, with T. vulgaris always more common than T. thalpophilus. Of the other thermophilic actinomycetes, F. rectivirgula was isolated predominantly from hay (44%) and S. viridis (56%) and T. sacchari (44%) from sugarcane bagasse. The largest populations of T. vulgaris and T. thalpophilus were found in paddy straw, followed by T. sacchari, S. viridis and F. rectivirgula in sugar-cane bagasse. The widespread occurrence of these clinically important thermophilic actinomycetes suggests that exposure of humans and animals to them may be frequent in north-western India. Studies are required to determine the prevalence of extrinsic allergic alveolitis (hypersensitivity pneumonitis) caused by thermophilic actinomycetes in the local population.

    Notes: Abstract The study was prompted by the lack of information on the role of thermophilic actinomycetes in hypersensitivity pneumonitis in India. It reports the occurrence of precipitating antibodies against clinically important thermophilic actinomycetes in the sera of a population sample of dairy herd workers, Nangali, Delhi. Of 112 workers investigated, 28 (25%) showed precipitins againstFaenia rectivirgula, 4 (3.2%) againstSaccharomonospora viridis, 2 againstThermoactinomyces thalpophilus and one each againstT. vulgaris andT. sacchari. The results of enzyme-linked immunosorbent assay (ELISA) indicated that IgG antibody activity againstF. rectivirgula was significantly higher in the symptomatic group than in the asymptomatic group (p〈0.05) of workers and the controls (p〈0.01). Significant difference inF. rectivirgula IgG activity was also obtained between the precipitin-positive symptomatic group and the precipitin-positive asymptomatic group (p〈 0.05). In strong contrast, the IgG antibody activity againstT. thalpophilus was found to be uniformly low. A limited aeromicrobiological sampling of the dairy farm revealedS. viridis (55.8%) to be the commonest species followed byT. vulgaris (19.2%),T. thalpophilus (18.5%),F. rectivirgula (5%) andT. sacchari (15%). On the basis of suggestive clinical and laboratory findings, farmer's lung disease was suspected in four dairy herd workers. A comprehensive clinical evaluation including pulmonary function studies on the dairy herd workers and their long-term follow-up is indicated to determine the extent of respiratory morbidity caused byF. rectivirgula, S. viridis, T. thalpophilus, T. sacchari andT. vulgaris in India.

    Notes: Abstract A rapid pigmentation test for identification ofCryptococcus neoformans is described. The method is based on the formation of a characteristic, mousegrey to violaceous-black pigment when shake cultures ofC. neoformans in a phosphate-buffered,l-DOPA — ferric citrate medium are incubated at 37 C for one hour.
