Jeotgalicoccus coquinae sp. nov. and Jeotgalicoccus aerolatus sp. nov., isolated from poultry houses

Two Gram-stain-positive, non-motile, non-spore-forming cocci (strains MK-7(T) and MPA-33(T)) were isolated from poultry houses. Strain MK-7T was isolated on marine broth agar from coquina, a food supplement for female ducks used in a duck-fattening farm. Strain MPA-33(T) was isolated from the air of a turkey house on TSA after filter sampling. On the basis of 16S rRNA gene sequence similarity studies, both strains were shown to belong to the genus Jeotgalicoccus; MK-7(T) was most closely related to Jeotgalicoccus psychrophilus YKJ-115(T) (99.3 % similarity) and MPA-33(T) was most closely related to Jeotgalicoccus halotolerans YKJ-101(T) (98.8 %). The quinone system of MK-7(T) was composed of equal amounts of menaquinones MK-7 and MK-6 and that of MPA-33(T) contained 76% MK-7 and 24% MK-6. The polar lipid profile of strain MK-7(T) consisted of the major compounds diphosphatidylglycerol and phosphatidylglycerol and six unidentified lipids present in minor to moderate amounts. In strain MPA-33(T), diphosphatidylglycerol was the single predominant lipid, whereas phosphatidylglycerol was detected in moderate amounts. In addition, one unidentified phospholipid and four unidentified lipids were detected. Fatty acid profiles with iso-15:0 and anteiso-15:0 as major fatty acids supported the affiliation of the strains to the genus Jeotgalicoccus. The results of physiological and biochemical tests as well as DNA DNA hybridizations allowed clear phenotypic differentiation of strains MK-7(T) and MPA-33(T) from the most closely related species. Strains MK-7(T) and MPA-33(T) therefore represent novel species, for which the names Jeotgalicoccus coquinae sp. nov. (type strain MK-7(T) =DSM 22419(T) =CCM 7682(T) =CCUG 57956(T)) and Jeotgalicoccus aerolatus sp. nov. (type strain MPA-33T =DSM 22420(T) =CCM 7679(T) =CCUG 57953(T)) are proposed.
