Isolation of a bacteriophage for Bdellovibrio bacteriovorus.
A phage infective for Bdellovibrio bacteriovorus was isolated. Electron microscopy revealed that it is tail-less, has a hexagonal appearance and two distinct capsomere layers, and is 60 to 70 nm in size. The nucleic acid appears to be single-stranded deoxyribonucleic acid. This is the first report of the isolation of a phage infective for B. bacteriovorus.
متن کاملChemotaxis by Bdellovibrio bacteriovorus toward prey.
A chemotaxis assay system that uses a modified Boyden chamber was characterized and used for measurements of chemotaxis by Bdellovibrio bacteriovorus strain UKi2 toward several bacterial species. Bacteria tested included both susceptible and nonsusceptible cells (Escherichia coli, Pseudomonas fluorescens, Bacillus megaterium, and B. bacteriovorus strains UKi2 and D). None was attractive to bdel...
متن کاملChemotaxis toward amino acids by Bdellovibrio bacteriovorus.
Chemotaxis toward amino acids by Bdellovibrio bacteriovorous strain UKi2 was studied by the capillary technique of Adler (J. Gen. Microbiol. 74:77-91, 1973). Chemotaxis was shown to be optimal when the capillaries were incubated at between 15 and 40 degrees C for 30 min; the optimal pH was between 7.0 and 8.2. The chemotactic response was proportional to the density of the suspension of bdellov...
متن کاملBdellovibrio bacteriovorus Parasitism in Shigella Species.
Bdellovibrio bacteriovorus was capable of parasitizing Shigella boydii, S. flexneri, and S. sonnei. The bdellovibrio was able to produce plaques on lawns consisting of heat-killed or ultraviolet-irradiated S. boydii.
متن کاملReward for Bdellovibrio bacteriovorus for preying on a polyhydroxyalkanoate producer.
Bdellovibrio bacteriovorus HD100 is an obligate predator that invades and grows within the periplasm of Gram-negative bacteria, including mcl-polyhydroxyalkanoate (PHA) producers such as Pseudomonas putida. We investigated the impact of prey PHA content on the predator fitness and the potential advantages for preying on a PHA producer. Using a new procedure to control P. putida KT2442 cell size...
