Cell mixtures of different species and strains of cellular slime moulds.
INTRODUCTION T H E cellular slime moulds have, in their life history, a period of feeding of separate independent amoebae which subsequently stream together (by a process involving chemotaxis) to central collection points. Each of the resulting cell-masses differentiates into a fruiting body; in most species there is a delicate tapering celluose stalk which surrounds the large vacuolate stalk-c...
متن کاملBreakdown of self/nonself recognition in cannibalistic strains of the predatory slime mold, Dictyostelium caveatum
Dictyostelium caveatum amebas feed upon both bacteria and the amebas of other cellular slime molds. The capacity to feed extensively upon other cellular slime molds is unique to D. caveatum amebas. They are able to phagocytose amebas larger than themselves by nibbling pieces of the cells until they are small enough to ingest. Here we report the isolation from previously cloned stock cultures of...
متن کاملInteractions among Variant and Wild-type Strains of Cellular Slime Molds across Thin Agar Membranes.
The present results suggest that light emission in luminous bacteria is under the control of at least two genetic factors which, as far as one can tell, do not affect other reactions essential for the growth of the organism. Bacterial luciferase is a flavoprotein which can catalyze the rapid oxidation of reduced pyridine nucleotides by molecular oxygen,2 and it may have figured more prominently...
متن کاملSlime production by Staphylococcus aureus strains isolated from cases of bovine mastitis.
The objective of the present research was to determine the frequency of slime production by Staphylococcus aureus strains recovered from bovine mastitis and comparison of slime formation frequency, depending on the determination procedure employed. The investigations embraced 59 Staphylococcus aureus strains obtained from the inflammatory secretion of mammary glands of 45 cows. Slime production...

Oestrogen receptor protein (ER) was detected in 9 of 11 samples of malignant breast tissue and 8 of 9 samples of normal breast tissue. Levels of cytosolic ER (ERJ) in malignant breast were 21-1102 fmol mgsoluble protein (Kd1.8x 10-9-3.1 x 10-8moll-1) and those of nucleosolic ER (ERj), 13-526fmolmg-' soluble protein (Kd 2.1 x 10-9-1.4 x 10 8mol '1). In normal breast tissue ERC levels were 33-640...
