More than 90 morphological and physiological characters of 546 strains of nonfermentative, nonfastidious, Gram negative bacteria isolated from clinical specimens were examined to determine those features most useful for the identification of these bacteria. The species examined included Moraxella osloensis, Mor. lacunata, Acinetobacter anitratum, Ac. haemolyticus subsp. haemolyticus, Ac. haemolyticus subsp. alcaligenes, Ac. Iwoffi, Alcaligenes faecalis, Alc. odorans var. viridans, Pseudomonas fluorescens, Ps. putida, Ps. pseudomallei, Ps. maltophilia, Ps. stutzeri, Ps. acidovorans, Ps. alcaligenes, and atypical strains of Ps. aeruginosa.

“…Under such conditions, nitrate must be reduced to ammonia, presumably through the intermediary formation of nitrite, so that cells can synthesize the amino groups of amino acids and other nitrogenous compounds. It has been shown that suspensions of Acinetobacter cells, which are grown in media containing nitrate as the source of nitrogen, possess nitrate reductase and nitrite reductase activities (34). When such cells are grown in the presence of amino acids, however, these reductase activities are completely repressed (34).…”

When such cells are grown in the presence of amino acids, however, these reductase activities are completely repressed (34). Since the test for ability to reduce nitrate to nitrite is generally performed by growing cells in complex, amino acid-containing media, it is understandable why such assays for appearance of nitrite are usually negative.…”

Interspecies Transformation of Acinetobacter : Genetic Evidence for a Ubiquitous Genus

The availability of a strain of Acinetobacter competent for transformation has made it possible to demonstrate the genetic relatedness of a large variety of gram-negative, oxidase-negative, nonmotile, and aerobic coccobacilli originally classified into eleven different genera. Deoxyribonucleic acid (DNA) species from 265 such strains are capable of transforming stable auxotrophs of the competent Acinetobacter to prototrophy. The compositions of these DNA species vary from 40 to 46.8% guanine plus cytosine. Strains with widely differing phenotypic properties are also included in this collection of acinetobacters. DNA species from all oxidase-positive strains of Moraxella and from a variety of common bacteria are unable fo transform the competent Acinetobacter. Although acinetobacters are usually considered to be unable to reduce nitrate to nitrite, six strains known to carry out this reduction have been shown to be authentic acinetobacters since their DNA species readily transform the competent Acinetobacter auxotrophs to prototrophy. In contrast to previous findings that acinetobacters rarely grow with glucose as a sole carbon source, the results of the present study show that 17 of the 265 strains grow readily in a glucosemineral medium, and 48 other strains can mutate spontaneously to grow in such a medium. A second competent strain of Acinetobacter, originally unable to use glucose, D-xylose, or D-ribose as carbon sources, has been transformed for ability to dissimilate these compounds using DNA species from strains that normally grow on these sugars. Although most of the 265 Acinetobacter strains studied were originally grown on complex media when isolated from human sources, only nine of these strains require growth factors in order to grow in a mineral medium containing a single carbon and energy source. A simple transformation assay has been devised for rapid examination of large numbers of strains to determine whether or not they are acinetobacters. This assay, which is suitable for routine diagnostic work, includes a procedure for preparation of crude transforming DNA from a small quantity of bacterial paste. Samples of DNA prepared from Acinetobacter cultures that had died on slants and plates were still able to effect transformation of the competent auxotrophs to prototrophy.

“…Nitrate is not reduced to nitrites (or reduced only slightly, for a light pink color of questionable significance may sometimes be seen after addition of the nitrite reagents), but this is apparently not due to failure of utilizing nitrate. Jyssum and Joner (297)(298)(299) found that a strain of B. anitratum could utilize nitrate or nitrite as sole source of nitrogen and that hydroxylamine was a possible intermediate in nitrate reduction. Juni (294) recently found that several strains of Herellea vaginicola reduced nitrate.…”
