Abstract
We report the first draft genome sequences of two isolates previously classified as CDC EF-4b species, Neisseria sp. 83E34 and Neisseria sp. 74A18. Both strains were isolated from patients with animal bites and likely constitute novel genomospecies with average nucleotide identities of <95% to other sequenced strains.
Highlights
CDC eugonic fermenter 4b (EF-4b) is a designation of Gramnegative bacteria that are members of animal oral flora and are typically isolated from animal bite wounds in humans [1]
In 2006, this group was identified as Neisseria zoodegmatis based on 16S sequence and biochemical testing [1,2,3]
Five isolates from human infections have been reported since the taxonomical classification of Neisseria zoodegmatis, while Ͼ30 isolates have been collected from CDC EF-4b bacteria [1, 4, 5]
Summary
CDC eugonic fermenter 4b (EF-4b) is a designation of Gramnegative bacteria that are members of animal oral flora and are typically isolated from animal bite wounds in humans [1]. In 2006, this group was identified as Neisseria zoodegmatis based on 16S sequence and biochemical testing [1,2,3]. Five isolates from human infections have been reported since the taxonomical classification of Neisseria zoodegmatis, while Ͼ30 isolates have been collected from CDC EF-4b bacteria [1, 4, 5]. CDC EF-4b has been cultured from a case of infectious tenosynovitis due to a Siberian tiger bite [6].
