Dg. Rodionov et Ee. Ishiguro, TEMPERATURE SENSITIVITY OF BACTERIOLYSIS INDUCED BY BETA-LACTAM ANTIBIOTICS IN AMINO ACID-DEPRIVED ESCHERICHIA-COLI, Journal of bacteriology, 180(8), 1998, pp. 2224-2227
The temperature-sensitive penicillin tolerance response previously rep
orted in amino acid-deprived Escherichia coli (W. Kusser and E. E. Ish
iguro, J. Bacteriol. 169:2310-2312, 1987) was not due to the induction
of the heat shock response resulting from a temperature upshift and w
as therefore unrelated to the findings of another report (J. K. Powell
and K. D. Young, J. Bacteriol. 173:4021-1026, 1991) indicating a posi
tive correlation between the expression of heat shock proteins and pen
icillin tolerance. The thermosensitive event occurred in the lysis ind
uction stage.
