We present edition VII of the linkage map of Salmonella typhimurium. We list a total of 750 genes; 680 of these are located on the linkage map, and the remaining 70 are not yet mapped, although mutant alleles are known. The first edition of the map (411) contained 133 genes. Later editions were published in 1967 (408), 1970 (409), 1972 (410), 1978 (412), and 1983 (418). All genes presently know...

the role of vi-capsular polysaccharide (vi-cps) in human immunity against infection caused by salmonella typhi is well known. the downstream process of purification generally causes depolymerization of vi-cps to a nonimmunogenic low molecular weight form. in the present study, a standard strain of sal. typhi ty6s was grown under submerge cultural conditions in a pilot-plant scale of 90 liter fe...

for the first time, dioxomolybdenum(vi) complex with the general formula [moo2l2] containing a n-o bidentate ligands (hl=2-(o-aminophenyl)- benzimidazole) has been used for the oxidation of sulfides. elemental analyses (carbon, hydrogen, nitrogen), ft-ir and uv-visble spectra and 1hnmr analysis agree well with the proposed stoicheiometry of the complex [moo2l2].  a variety of sulfides were smoo...

Vanadium (III) gives a greenish- yellow complex with anthranilic acid in presence of pyridine. The complex is extractable with chloroform and is used for photometric determination of vanadium by measuring the absorbance at 390 nm against a reagent blank. Beer's Law holds good in the range of 1-20 pg V/ml. Moderate amounts of Pb (II) , Ca (II) , Sr (II) , Ba (II) , Cd (II) , Mg (II) , Mn (II...

This article summarizes current knowledge on the genetics and possible molecular mechanisms of Human pathologies resulted from mutations within the genes encoding several myosin isoforms. Mutations within the genes encoding some myosin isoforms have been found to be responsible for blindness (myosins III and VIIA), deafness (myosins I, IIA, IIIA, VI, VIIA and XV) and familial hypertrophic cardi...

The facultative pathogen Vibrio cholerae transitions between its human host and aquatic reservoirs where it colonizes chitinous surfaces. Growth on chitin induces expression of chitin utilization genes, genes involved in DNA uptake by natural transformation, and a type VI secretion system that allows contact-dependent killing of neighboring bacteria. We have previously shown that the transcript...
