Five replicates of 48 pigs each, weaned at 12–14 d of age, were observed. Mean preferred temperature was found to decrease during the night and early morning, and increase during the day. Average preferred temperatures were 26.3°C, 25.7°C, and 25.3 °C for 3, 4, and 5 wk of age, respectively. Key words: Temperature preference, pigs, early weaned, operant conditioning

Preferred temperatures of underyearling rainbow trout (Salmo gairdneri) were determined in both vertical and horizontal temperature gradients. No statistically significant difference was found between the preferred temperatures by the two different methods. This suggests that the nature of the gradient plays a lesser role than generally believed in laboratory investigations of temperature preference.

Cell wall-deficient bacteria (CWDB) are pleomorphic bacterial forms. These atypical organisms may occur naturally or they can be induced in the laboratory. Their presence has been known about for over a century, but a definite link to clinical disease outcomes has not been demonstrated. A number of case reports and laboratory studies suggest some disease associations, however. Considerable controversy surrounds the true relevance of CWDB to disease; there is a widespread belief that they may represent a response by the walled organism to adverse extracellular conditions like antibiotic pressure. This review looks at studies published between 1934 and 2003, which were identified by Dialog DataStar using the key words ‘cell wall deficient bacteria and clinical significance and infections’ and by further scanning the reference list at the end of the papers retrieved. We conclude that the evidence for the clinical significance of CWDB in disease is not compelling.

A temperature-sensitive mutation in the murH gene of Escherichia coli confers a lysis phenotype at the restrictive temperature. An extragenic suppressor of murH apparently representing a new locus at 12.5 min on the linkage map and designated smhB is described. The smhB mutation by itself also conferred a temperature-sensitive lysis phenotype. A mutation in another new locus designated lytD which arose spontaneously in the smhB mutant was mapped close to smhB at 12.7 min on the linkage map. The lytD mutation by itself conferred a temperature-sensitive lysis phenotype indistinguishable from that of the murH mutant. Thus, the suppression of lysis in the smhB murH and the smhB lytD double mutants suggests a mechanism involving the reciprocal suppression of the two individual lysis-causing mutant alleles. The suppressor activity of smhB was apparently relatively specific in that smhB failed to prevent lysis induced by either mutational (murE or murF) or antibiotic-induced blocks in peptidoglycan synthesis. This suggests that murH, smhB, and lytD may be functionally related. Key words: temperature-sensitive mutation, Escherichia coli, lysis phenotype, suppression.
