A study of air-borne Cladosporium
The viability of air-borne Cladosporium was studied by means of a slit sampler. From the results obtained it was concluded that the numbers of non-viable Cladosporium dispersion units in the autumn air at London is insignificant. A series of air-borne spore samples, taken by means of a cascade impactor and a slit sampler, showed that there was little to choose between the relative efficiencies of the two methods.
Summary ::: Thirty-two cases of histoplasmosis, thirteen of which have not yet appeared in the literature, are reviewed. The spontaneous infection in animals is also noted. The disease is widely distributed throughout the world and will undoubtedly be recognized with increasing frequency in the future. Diagnosis and the possibilities of successful treatment are discussed.
