Serotype c Streptococcus mutans mutatable to lactate dehydrogenase deficiency.

Three lactate-dehydrogenase-deficient mutants of serotype c S. mutans were made by using, as parents, two serotype c strains that produced unusually large amounts of ethanol, acetic acid, and acetoin, and very little lactic acid, when grown in broth containing a limiting amount of glucose. The mutants, obtained with N-methyl-N'-nitro-N-nitrosoguanidine, were stable during 12 weeks of daily subculture in broth. Crude cell-free extracts of the mutants had less than 1% of the LDH-specific activity of their parent strains. The serotype c mutants resembled serotype g mutants in having molar growth yields at least as high as those of their parents. However, in contrast to the g mutants, the c mutants produced cell crops (cell mass per ml medium) that were as high as those of their parent strains.

Indomethacin therapy in hydramnios.

AIM: The use of indomethacin in treatment of hydramnios was evaluated. SUBJECTS & METHODS: Twelve patients with symptomatic hydramnios were treated with indomethacin (2.2- 3.0 mg/kg body weight/day). RESULTS: The treatment was started at a gestational age of 31.17-/+7.94 weeks and continued for 3.74-/+2.3 weeks. Eleven patients responded to the therapy both subjectively and objectively and pregnancies were prolonged by 4.6-/+3.1 weeks (range 0.1-10 weeks). Five women had term deliveries. Six patients had a favourable perinatal outcome. Four patients who had a known congenital anomaly in the foetus, delivered stillborn babies or had an early neonatal death. One patient who did not follow up after commencing therapy delivered a full-term stillbirth. One patient delivered within 1 day of starting therapy. Indomethacin therapy caused no maternal complications. CONCLUSION: Indomethacin was effective in the management of hydramnios and preventing it's complications.
