City spore concentrations in the European Economic Community (EEC). IV. Summer weed pollen (Rumex, Plantago, Chenopodiaceae, Artemisia), 1976 and 1977.

This paper describes observations on the airborne pollen concentrations of four anemophilous weeds of very common occurrence in Western Europe, viz. Rumex spp .(sorrel and dock), Plantago spp. (plantain), Chenopodiaceae (goosefoot family) and Artemisia spp. (mugwort). Comparative results are recorded from London, Leiden, Brussels, Munich and Marseilles for the summers of 1976 and 1977 and this study is one of a series involving international collaboration between workers in cities of the European Economic Community. The literature on the clinical significance of summer weed pollen is reviewed and it is concluded that the pollen of Artemisia is likely to be of importance in areas where the weed is of common occurrence in late summer. The pollen of the other summer weeds is unlikely to be important, but may contribute to the problems of the pollen sensitive patient under exceptional circumstances.

[Spore concentration in cities of the European Economic Community. II. Spores of Cladosporium and Alternaria].

A comparative account of Alternaria and Cladosporium spore concentrations in four cities in the European Economic Community (EEC), is given for the years 1973 and 1974. Sijilar volumetric air sampling methods were employed in each of the cities, and concentrations of 3000 Cladosporium spores and 100 Alternaria spores/m3 were taken as the threshold concentrations for clinical significance. With Cladosporium, although highest concentrations were observed in Brussels, the differences were less marked at the other stations. Highest Alternaria concentrations were reocrded in Brussels, followed by London, Leiden and Munich. During the 2 years studied, the average number of days with spore concentrations greater than the threshold value for Cladosporium were 59 in Brussels, 36 in Leiden, 38 in London and 46 in Munich and for Alternaria, 48 in Brussels, 13 in Leiden, 33 in London and 5 in Munich.

City spore concentrations in the European Economic Community (EEC) I. Grass pollen, 1973.

Although clinical reports on the prevalence of summer hay fever in different parts of Europe have been published, comparative studies on atmospheric pollen concentrations appear to have been rarely undertaken. The present paper describes observations on the grass pollen content of the air at Bologna, Brussels, London, Munich and Strasbourg and is the first of a series involving international collaboration between workers in cities of the European Economic Community.

Fungal contamination of the floors of swimming pools, particularly subtropical swimming paradises.

We compared the level of dermatophyte contamination of the floors of traditional swimming pools and of subtropical swimming paradises, a new type of indoor swimming pool introduced in Belgium in 1981. From the results of routine hygiene inspections over several years and of a comparative study, we can conclude that the floors of subtropical swimming pools are much more highly contaminated by dermatophytes than the floors of traditional swimming pools. This higher degree of contamination is due to the huge number of visitors, the complexity of construction, the choice of materials and the long opening hours. In both types of swimming pools, the predominant species was Trichophyton mentagrophytes var. interdigitale, followed by T. rubrum. Other dermatophytes, such as Microsporum canis and M. gypseum, were isolated sporadically.

Typing by immunoblot of Aspergillus fumigatus from nosocomial infections.

Forty-four isolates of Aspergillus fumigatus from patients with nosocomial aspergillosis and their hospital environment were collected and typed by immunoblot. Laser densitometric analysis of the profiles and homology studies within each case were performed which established relationships between patient and environmental types and showed that patients are often contaminated by several types of A. fumigatus, not all necessarily responsible for the mycosis. One of the cases appeared to be a typical clonal hospital-acquired infection. This typing technique seems to represent a powerful tool to determine the origin and mode of spread of nosocomial aspergillosis.
