Spore count

Cucumbers and cabbage fermented by lactobacilli are popular dishes in the central and eastern Europe. Sauerkraut is frequently consumed by low-income communities, especially in winter. Surprisingly, no cases of botulism have been linked to consumption of such products. This observation may be explained based on the results of studies carried out by Braconnier et al. (2003). The authors analyzed germination of spores of C. botulinum type A and B, as well as changes in spore counts, in mushroom, broccoli, and potato purees. The addition of mixtures containing L-cysteine, L-alanine, and sodium lactate to... 

Daily pollen and spore counts provide a snapshot of the atmosphere in a given area and typically represent the average daily concentration from a single air sampler. However, a great deal of variability exists within the atmosphere and physicians should be aware of the clinical implications of this variability. Major causes of variability relate to the diurnal rhythms of spore discharge, discharge related to weather events, seasonal effects, and spatial effects. Also contributing to variability are the ways that different spore types respond to environmental conditions. 

The variability in the atmosphere means that the average spore count does not apply to all times of the day or to all parts of a city (or region). There are additional sources of variance not related to the atmosphere that the physician should also recognize. Although the Burkard (Hirst-type) spore trap is one of the most widely used air-sampling instruments, there is no standard counting method used in analyzing the spores or pollen captured by this type of sampler. The most accurate method of analysis would be to count the entire exposed surface however, this is not practical because of time limitations. As a result only a portion of the daily capture is counted. Because the sampler drum with attached tape moves at 2 mm per hour by the intake orifice, microscopic...
