Four bacterial strains, A-IN1T, A-TC2T, E-TC7T, and K-TC2T, isolated from soil-borne nematodes of the species Oscheius tipulae Acrobeloides bodenheimeri, were found to represent new genera Acinetobacter, Alcaligenes, Enterobacter, Kaistia, respectively. In this study, we described these using a polyphasic taxonomic approach that included whole-genome whole-proteome phylogenomic reconstructions,...

Background Alcaligenes faecalis (A.faecalis) is a Gramnegative, rod-shaped, motile, oxidase, catalase and citrate positive obligate aerobe that is commonly found in the environment. A. faecalis is the most frequently isolated member of family Alcaligenaceae in the clinical laboratory. Infections caused by A. faecalis are opportunistic and are acquired from moist items such as nebulizers, respir...

Soil microorganisms are important sources of the nitrogen trace gases NO and N2O for the atmosphere. Present evidence suggests that autotrophic nitrifiers such as Nitrosomonas europaea are the primary producers of NO and N2O in aerobic soils, whereas denitrifiers such as Pseudomonas spp. or Alcaligenes spp. are responsible for most of the NO and N2O emissions from anaerobic soils. It has been s...

It has been shown that, although iodinated swimming-pool waters are usually free from coliform bacteria and enterococci, the total counts frequently become relatively high. Pseudomonas alcaligenes and Alcaligenes faecalis have been shown to account for most of these high counts. It was of interest, therefore, to compare the microbial flora of four alternately chlorinated and iodinated swimming ...

We found that 20 (10.6%) of 188 patients with chronic suppurative otitis media in Angola were co-colonized with fluoroquinolone-resistant Alcaligenes faecalis, commonly found in birds. A likely explanation for our findings was the use of bird feces by residents as a traditional remedy to prevent ear secretions caused by primary ear infection.
