ASM journals are the most prominent publications in the field, delivering up-to-date and authoritative coverage of both basic and clinical microbiology.

None of the misidentified strains was ADO or d-CEL positive. Soil and sediments were suspended in modified buffered peptone water with sodium pyruvate (mBPWp). This has resulted in very fragmented …

Modified Moore swabs were immersed in mBPWp. ↵▿ Published ahead of print on 30 December 2008. All misidentified E. coli O157:H7 strains and the “low-discrimination” strains shared the SAC-negative phenotype. Escherichia fergusonii has been associated with a wide variety of intestinal and extra-intestinal infections in both humans and animals but, despite strong circumstantial evidence, the degree to which the organism is responsible for the pathologies identified remains uncertain.

Bacterial identification was performed using the Vitek2 ID-GN system (bioMérieux). The identification test was repeated three times by three different operators and generated the following result: E. fergusonii, 99%, excellent identification. A biotype is defined as a group of strains that have a common biochemical reaction pattern that is unusual for the particular species ( 4 , 7 ). Confirmation that the organism is ADO and d -CEL positive is critical.

A state and federal collaborative investigation of watershed contamination was conducted in the Salinas Valley of California from October 2005 to September 2006. Such clones often posses plasmids which provide them with special virulence traits. In those species which are inhabitants of the gastrointestinal tracts of warm-blooded animals, Escherichia species provide a portion of the microbially derived vitamin K for their host. The E. coli O157 strains with 97 to 99% probabilities were all SAC positive and were variable or negative in the above three reactions. A biotype is defined as a group of strains that have a common biochemical reaction pattern that is unusual for the particular species (4, 7). Journal of Microbiology & Biology Education, Microbiology and Molecular Biology Reviews, Submission, Review, & Publication Processes, Misidentification of a Variant Biotype of Escherichia coli O157:H7 as Escherichia fergusonii by Vitek 2 Compact.

Washington, DC 20036 Escherichia fergusonii is the bacteria that is most closely related to E.coli.

The 23 isolates were MUG negative and O157:H7 serology positive and contained the stx1, stx2, and uidAm genes.

We do not retain these email addresses. The misidentified strains were negative for these three biochemicals. 16S rRNA analysis cannot provide a good identification (Ma-heux et al. 1752 N St. NW The Gram-negative genus Escherichia is composed of five species: E. albetii, E. coli, E. fergusonii, E. hermanii and E. vulneris, with E. coli as the type-species.

The consequences of misidentifying E. coli O157:H7 are severe. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. They are Gram-negative rods, oxidase negative, catalase positive, and usually motile, reduce nitrate to nitrite and ferment D-glucose. The “contraindicating typical biopattern(s)” listed negative SAC at 99% probability.

Relevant biochemical reactions are given in Table 1. 2011). E. coli and E. fergusonii isolates and biochemical reactions from Vitek 2 Compact. Thank you for sharing this Journal of Clinical Microbiology article. A few Escherichia fergusonii strains gave weak hybridization signals in response to both probes at 65 degrees C but not at 68 degrees C. None of the other bacterial species tested were detected by either probe. Escherichia fergusonii has been associated with a wide variety of intestinal and extra-intestinal infections in both humans and animals but, despite strong circumstantial evidence, the degree to which the organism is responsible for the pathologies identified remains uncertain.

Of the 23 isolates, 15 were misidentified by Vitek 2 Compact version 01.02 0.01.04 as Escherichia fergusonii with 99% probability and no contraindications, requiring 5 h to complete analysis.

Subsequently, 32 strains, including E. coli O157 of both high and low probability, previously misidentified E. coli O157, and E. fergusonii from human and animal sources were run on Vitek 2 Compact on the same day, controlling other factors. Eight were identified as “low discrimination,” with “analysis organisms and tests to separate” given as Escherichia coli O157 and Escherichia coli. Nevertheless, discriminating inactive E. coli, E. albertii and E. fergusonii from other Escherichia species is much more difficult. Surface water from creeks, agricultural drainage ditches, sloughs, and a river, modified Moore swabs placed in flowing surface water, and creek sediment and soil samples were obtained and examined for E. coli O157:H7 (3, 6). 2011).
