Emulsan production by Acinetobacter calcoaceticus in the presence of chloramphenicol.
When exponentially growing cultures of Acinetobacter calcoaceticus RAG-1 or RAG-92 were either treated with inhibitors of protein synthesis or starved for a required amino acid, there was a stimulation in the production of emulsan, an extracellular polyanionic emulsifier. Emulsan synthesis in the presence of chloramphenicol was dependent on utilizable sources of carbon and nitrogen and was inhi...
متن کاملSerotyping of Acinetobacter calcoaceticus.
Serotyping of Acinetobacter calcoaceticus by direct immunofluorescence and a capsule swelling reaction is described. One hundred isolates, including 12 from an outbreak in a neonatal department, were studied. Ninety five per cent of the isolates were typable by immunofluorescence and could be divided into 30 separate types, but 42.1% of typable strains, including 11 from the outbreak, were of o...
متن کاملRecurrent bacteremia caused by the Acinetobacter calcoaceticus-Acinetobacter baumannii complex.
This study investigated the clinical and microbiological characteristics of patients with recurrent bacteremia caused by the Acinetobacter calcoaceticus-Acinetobacter baumannii (ACB) complex at a medical center. All ACB complex isolates associated with recurrent bacteremia were identified to the genomic species level using a 16S-23S rRNA gene intergenic spacer sequence-based method. Genotypes w...
متن کاملChromosome mapping in Acinetobacter calcoaceticus.
RP4-mediated conjugation was used to map the loci of 23 different mutations on a circular linkage group in Acinetobacter calcoaceticus EBF65/65. The resulting genetic map indicated that the chromosomal organization of A. calcoaceticus differed from that of members of the enteric group of bacteria and was similar to Pseudomonas in showing an absence of clustering of functionally related genes.
متن کاملGenetic analysis of Acinetobacter calcoaceticus proline auxotrophs.
Twenty-six Acinetobacter calcoaceticus proline auxotrophs were isolated after ethyl methane sulfonate mutagenesis. Studies using the efficient transformation system of this organism indicate that the mutations comprise therr genetically distinct groups.
