catelliCoccus marimammalium gen nov sp nov a novel gram positive catalase negative Coccus shaped bacterium from porpoise and grey seal
International Journal of Systematic and Evolutionary Microbiology, 2006Co-Authors: Paul A Lawson, Matthew D Collins, Enevold Falsen, Geoffrey FosterAbstract:Two strains of an unknown Gram-positive, catalase-negative, facultatively anaerobic, Coccus-shaped bacterium, originating from a porpoise and a grey seal, were characterized using phenotypic, biochemical and molecular phylogenetic methods. Chemical studies revealed the presence of a cell-wall murein based on l-lysine (type l-lys–gly–d-Asp) and a DNA G+C content of 38 mol%. Comparative 16S rRNA gene sequencing showed that this unidentified Coccus-shaped organism formed a hitherto unknown subline closely related to, albeit distinct from, a number of other catalase-negative genera which included EnteroCoccus, MelissoCoccus, TetragenoCoccus and VagoCoccus. Other known Gram-positive, catalase-negative taxa were more distantly related. Tree-branching considerations and sequence divergence values of >6 % with recognized taxa were indicative of this novel bacterium representing a separate genus. Based on phenotypic and phylogenetic evidence, it is proposed that this unknown bacterium, recovered from a porpoise and a grey seal, be classified as a novel genus and species, CatelliCoccus marimammalium gen. nov., sp. nov. The type strain is M35/04/3T (=CCUG 49459T=CIP 108575T).

atopoCoccus tabaci gen nov sp nov a novel gram positive catalase negative Coccus shaped bacterium isolated from tobacco
International Journal of Systematic and Evolutionary Microbiology, 2005Co-Authors: Matthew D Collins, Anna Wiernik, Enevold Falsen, Paul A LawsonAbstract:A novel Gram-positive, aerobic, catalase-negative, Coccus-shaped organism originating from tobacco was characterized using phenotypic and molecular taxonomic methods. The organism contained a cell wall murein based on l-lysine (variation A4α, type l-lysine–l-glutamic acid), synthesized long-chain cellular fatty acids of the straight-chain saturated and monounsaturated types (with C16 : 1 ω9, C16 : 0 and C18 : 1 ω9 predominating) and possessed a DNA G+C content of 46 mol%. Based on morphological, biochemical and chemical characteristics, the Coccus-shaped organism did not conform to any presently recognized taxon. Comparative 16S rRNA gene sequencing studies confirmed the distinctiveness of the unknown Coccus, with the bacterium displaying sequence divergence values of greater than 7 % with other recognized Gram-positive taxa. Treeing analysis reinforced its distinctiveness, with the unidentified organism forming a relatively long subline branching at the periphery of an rRNA gene sequence cluster which encompasses the genera AlloioCoccus, Allofustis, Alkalibacterium, Atopostipes, Dolosigranulum and Marinilactibacillus. Based on phenotypic and molecular phylogenetic evidence, it is proposed that the unknown organism from tobacco be classified as a new genus and species, AtopoCoccus tabaci gen. nov., sp. nov. The type strain of AtopoCoccus tabaci is CCUG 48253T (=CIP 108502T).

fastidiosipila sanguinis gen nov sp nov a new gram positive Coccus shaped organism from human blood
International Journal of Systematic and Evolutionary Microbiology, 2005Co-Authors: Enevold Falsen, Yuli Song, Sydney M. Finegold, Matthew D Collins, Christina Welinderolsson, Paul A LawsonAbstract:Phenotypic and phylogenetic studies were performed on two strains of an unidentified Gram-positive, fastidious, non-spore-forming, Coccus-shaped bacterium recovered from human blood. The organism was catalase-negative and grew under strictly anaerobic conditions and in the presence of 2 and 6 % O(2). Comparative 16S rRNA gene sequencing demonstrated that the unidentified bacterium was, phylogenetically, far removed from peptostreptococci and related Gram-positive Coccus-shaped organisms, but exhibited a phylogenetic association with Clostridium rRNA cluster III [as defined by Collins et al., Int J Syst Bacteriol 44 (1994), 812-826]. Sequence divergence values of 15 % or more were observed between the unidentified bacterium and all other recognized species within this and related rRNA clostridial clusters. Treeing analysis showed that the unknown bacterium formed a deep line branching at the periphery of rRNA cluster III and represents a hitherto unknown genus within this supra-generic grouping. On the basis of both phylogenetic and phenotypic evidence, it is proposed that the unknown bacterium from blood be classified in a new genus, Fastidiosipila gen. nov., as Fastidiosipila sanguinis sp. nov. The type strain of Fastidiosipila sanguinis is CCUG 47711(T) (=CIP 108292(T)).

staphyloCoccus lutrae sp nov a new coagulase positive species isolated from otters
International Journal of Systematic and Evolutionary Microbiology, 1997Co-Authors: Geoffrey Foster, H M Ross, Roger A Hutson, Matthew D CollinsAbstract:Phenotypic and phylogenetic studies were performed with three strains of a catalase-positive, gram-positive, Coccus-shaped bacterium isolated from otters. The results of a 16S rRNA gene sequence analysis demonstrated that these strains represent a hitherto unknown subline within the genus StaphyloCoccus. Based on the results of the phylogenetic analysis and phenotypic criteria, we propose that these bacteria should be classified as members of a new species, StaphyloCoccus lutrae. The type strain of S. lutrae is DSM 10244.

survey of brown soft scale Coccus hesperidum l parasitoids in southern california citrus
Biological Control, 2007Co-Authors: Apostolos Kapranas, Joseph G Morse, P Pacheco, Lisa Forster, Robert F LuckAbstract:The parasitoid complex of brown soft scale, Coccus hesperidum L., a multivoltine soft scale, was determined in southern California citrus over the period February 2004–March 2006. The survey was conducted by placing brown soft scale-infested yucca leaves in the canopy of citrus trees and subsequently rearing individually isolated parasitized scales in the laboratory. A total of 14 species parasitized brown soft scale in the field, the most abundant ones belonging to the genus Metaphycus Mercet (75%). The most abundant parasitoid species was Metaphycus angustifrons Compere (38% parasitism), and this is a new record of establishment for this species in California. Coccophagus species accounted for only 11% parasitism. There were important spatio-temporal differences across the parasitoid complex survey locations. We also found that the five most abundant encyrtid parasitoid species showed preferences for scales of different sizes. Our results have implications for biological control of citricola scale, Coccus pseudomagnoliarum (Kuwana), an important pest of citrus in the San Joaquin Valley of central California. Notably, this species is nearly absent in southern California. Brown soft scale is considered to be an alternate host for parasitoids of citricola scale, a univoltine soft scale, at times when the latter species is unavailable for parasitism.
