Deletions in the tetracycline resistance determinant reduce the thermosensitivity of a trfA(Ts) derivative of plasmid RP1 in Pseudomonas aeruginosa.
A derivative of the broad-host-range plasmid RP1, pME301, was temperature-sensitive (Ts) at 43 degrees C for maintenance in Pseudomonas aeruginosa, P. mendocina, Klebsiella aerogenes and Escherichia coli. In E. coli, the Ts defect of pME301 could be complemented in trans by the cloned trfA gene, which is known to be essential for RP1 replication in E. coli and P. aeruginosa. Because pME301 expressed a Ts phenotype in P. mendocina and K. aerogenes, we assume that the trfA function is also vital in these organisms. When plasmid-encoded carbenicillin resistance (on transposon Tn801) was selected at non-permissive temperatures in P. aeruginosa strain PAO carrying pME301, we obtained either Tn801 insertions into the chromosome or pME301 derivatives having a deletion (or point mutation) in their tet genes, which determine resistance to tetracycline and are not transposable. From cloning experiments, we infer that the tet gene product(s) destabilize the pME301 replicon in P. aeruginosa at 40-43 degrees C.

[L-2-hydroxyglutaric aciduria -- a rare cause of macrocephaly].
We report on a 9-year-old girl who was referred to our department because of increasing macrocephaly and school problems. The neurological examination disclosed mild cerebellar dysfunction and positive pyramidal tract signs. An MRI of the brain revealed extensive signal alterations of the white matter. Biochemical investigations established the diagnosis of L-2-hydroxyglutaric aciduria which has to be kept in mind as a rare cause of macrocephaly.
