The nucleotide sequence of genes involved in the leucine biosynthetic pathway of Clostridium pasteurianum.

A 2.2 kb SphI/ClaI fragment of the Clostridium pasteurianum chromosome has previously been cloned and shown to complement leuB401 and leuC171 mutations in Escherichia coli. The nucleotide sequence of this fragment has been determined (2327 bp) and carries three open reading frames. The products of translation of these reading frames display significant homologies with the alpha-isopropylmalate isomerase subunit (leuD) gene of Salmonella typhimurium, the beta-isopropylmalate dehydrogenase (leuB) genes of several organisms, and the dihydroxyacid dehydrase (ilvD) gene of E. coli.

Properties of influenza C virus grown in cell culture.

Influenza C virus was propagated successfully in primary chicken embryo lung (CEL) and fibroblast cells and in Madin-Darby canine kidney (MDCK) cells. In other cell lines, either no virus or only noninfectious hemagglutinin (HA) was produced. In productively infected cells (CEL), HA and infectious virus appeared by 24 h and reached a maximum by 36 to 48 h, cell-associated virus remaining at a constant low level. Infected Vero cells produced noninfective HA by 24 h which also remained predominantly cell associated until 60 to 72 h, when the cells disintegrated. Viral antigen was demonstrable on membranes of both CEL- and Vero-infected cells at 24 h; Vero cells yielded membrane vesicles containing HA, but none of the spherical or filamentous viral particles synthesized in CEL cells. Influenza C virus produced in cell culture or in eggs differed in several important respects from A and B viruses and from Newcastle diseases virus. All influenza C preparations, regardless of infectivity or source, lacked detectable neuraminidase activity, yet retained the ability specifically to inactivate receptors only for influenza C. Influenza C HA was not inhibited by soluble glycoproteins highly active against HA of A virus. A rat serum glycoprotein uniquely inhibited influenza C by binding to the surface components of virious.
