title: The effect of the fungus Clavatia utriformis on the morphological picture and physiological behaviour of bacteria.
abstract: When investigating the effect of various fungi on various bacteria, we found that the edible fungus Clavatia caelata (utriformis) affected the bacteria Alcaligenes faecalis in a triple way. A large zone of inhibition of these bacteria was found around the piece of this fungus. Bacteria growing in the outer, i.e., bacteriostatic zone, were morphologically changed/mostly elongated, but also thickened) and also enhanced in their haemolysis. These features are similar to those of some bacteria when under the influence of some antibiotics (esp. penicillins). These changes were only phenotypic. The changed bacterial forms reverted to normal bacterial form and normal haemolysis in 24 hrs. after the transfer to a medium without the influence of the fungus.
