EMENDED DESCRIPTION OF AURITIDIBACTER IGNAVUS YASSIN ET AL. 2011 View in CoL

Auritidibacter ignavus (ig.na′ vus. L. masc. adj. ignavus inactive).

In addition to properties described for the emended genus or as described for A. ignavus by Yassin et al. [ 1], strains may show the following characteristics: cells measure 1.85±0.45 µm in length and have a width of 0.44±0.05 µm. May assimilate substrate at pH 6. Reduction of nitrite not observed. Vogues–Proskauer (acetoin) production, DNase and starch hydrolyses are variable. Pyrrolidonyl arylamidase, esterase, leucine arylamidase and naphthol-AS-BIphosphohydrolase are variable. Isolates may grow at 42 °C and not at 25 °C. Isolates neither ferment nor assimilate conventional sugars nor those found in API panels. Using the Biolog panel, isolates may be positive or borderline positive for the utilization of dextrin, L-glutamic acid,L-pyroglutamic acid, p -hydroxyphenylacetic acid, D-galacturonic acid, L-lactic acid, Tween 40, Ɣ- aminobutyric acid, α-hydroxybutyric acid, β-hydroxy-DL-butyric acid, α-ketobutyric acid and acetic acid. In sensitivity tests, tetrazolium dyes may be reduced at pH 6, in 1%, 4%, and 8% NaCl, nalidixic acid, lithium chloride, potassium tellurite, aztreonam, sodium butyrate and sodium bromate. The remaining substrates are variably utilized or not used.

Isolates have been obtained from ear infections from patients located in Germany, Switzerland and Canada and detected by DNA sequencing from a bacteremia in Spain. A. ignavus NML 100628 has been deposited in two culture collections (NCTC 14178=LMG 30897) to serve as an additional reference strain for this species. The genomic DNA G+C content of the type strain ( A. ignavus DSM 45359 T) is 59.3% with those of other strains ranging from 59.4 to 59.5%.
