PURPOSE
is a rare pathogen. Keratitis from this organism has never been specifically reported or described. In this report we provide the first clinical description and photograph of infectious keratitis.
OBSERVATIONS
A 41 year-old man presented with a three day history of left eye pain. He was found to have a corneal ring ulcer and infiltrate from which was cultured. The patient was successfully treated with intensive topical gatifloxacin (0.5%) and fortified tobramycin (1.5%); oral doxycycline was added to reduce corneal thinning. The patient's infection resolved with a residual scar and final best corrected visual acuity of 20/200 OS.
CONCLUSIONS AND IMPORTANCE
can present as a ring-shaped infectious corneal infiltrate and ulcer. Ring infiltrates have been observed with other microorganisms, including several other gram negative bacteria and classically, acanthamoeba. Frequently presumed to be purely immunologic, corneal ring infiltrates can have a number of other etiologies, including infectious and toxic. There are different types of immunologic rings as well, making differentiation of corneal rings sometimes difficult for the ophthalmologic generalist and subspecialist alike. In this paper we discuss characteristics of various corneal ring infiltrates, along with their immune pathophysiology. Infectious rings are distinguished from immunologic Wessely rings.

Cultural and chemical characterization of CDC groups EO-2, M-5, and M-6, Moraxella (Moraxella) species, Oligella urethralis, Acinetobacter species, and Psychrobacter immobilis.
We determined phenotypic characteristics, cellular fatty acid composition, and isoprenoid quinone content of representative strains of CDC groups EO-2, M-5, and M-6, Moraxella (Moraxella) species, Oligella urethralis, Acinetobacter species, and Psychrobacter immobilis. All organisms contained ubiquinone with eight isoprene units as the major isoprenolog, but distinct differences were observed in fatty acid composition. Twenty-eight of the original collection of CDC group EO-2 strains were further identified as P. immobilis, EO-2, or EO-3 by distinctive cellular fatty acid profiles, cellular morphology, and pigment production. The cellular fatty acid compositions of M-5 and M-6 were similar but were clearly different from those of other organisms. The genus Acinetobacter was differentiated from other organisms in the study by small amounts of 2-hydroxydodecanoic acid (2-OH-12:0), and P. immobilis was differentiated by small amounts of decanoic acid (10:0) and a branched-chain 17-carbon acid (i-17:0). All Moraxella species were distinguished by small amounts of decanoic acid (10:0) and the absence of i-17:0. M. bovis, M. nonliquefaciens, and some strains of M. lacunata formed a single fatty acid group, while M. osloensis, M. phenylpyruvica, M. atlantae, and other strains of M. lacunata (M. lacunata II) had species-specific fatty acid profiles. O. urethralis differed from Moraxella species by the presence of large amounts (49%) of cis-vaccenic acid (18:1 omega 7c), small amounts (1%) of 3-hydroxyhexadecanoate (3-OH-16:0), and the absence of 10:0 and 3-hydroxydodecanoate (3-OH-12:0). The combined use of chemical data and a small number of conventional tests permitted rapid identification and differentiation of these organisms from each other and from related organisms.

A gram-negative alkaline phosphatase- and pyrrolidone peptidase-positive rod-shaped bacterium (CCUG 45702) was isolated from two aerobic blood cultures from a female cancer patient. No identification could be reached using phenotypic techniques. Amplification of the tRNA intergenic spacers revealed fragments with lengths of 116, 133, and 270 bp, but no such pattern was present in our reference library. Sequencing of the 16S rRNA gene revealed its identity as Moraxella atlantae, a species isolated only rarely and published only once as causing infection. In retrospect, the phenotypic characteristics fit the identification as M. atlantae (formerly known as CDC group M-3). Comparative 16S rRNA sequence analysis indicates that M. atlantae, M. lincolnii, and M. osloensis might constitute three separate genera within the MORAXELLACEAE: After treatment with amoxicillin-clavulanic acid for 2 days, fever subsided and the patient was dismissed.
