Genetic 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.
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 کاملComplete Genome Sequence and Methylome Analysis of Acinetobacter calcoaceticus 65
Acinetobacter calcoaceticus 65 is the original source strain for the restriction enzyme Acc65I. Its complete sequence and full methylome were determined using single-molecule real-time (SMRT) sequencing.
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 کاملDefining resistance in Acinetobacter calcoaceticus-Acinetobacter baumannii complex strains.
We read with great interest the recent publication of Tien and colleagues in which they describe the antimicrobial susceptibilities of a large number of Acinetobacter baumannii-Acinetobacter calcoaceticus strains isolated from a medical center in Taiwan (1). They suggested that antimicrobial susceptibility was negatively associated with virulent potential because more-susceptible strains were r...
