Microbial Contaminants of Cord Blood Units Identified by 16S rRNA Sequencing and by API Test System, and Antibiotic Sensitivity Profiling.

Over a period of ten months a total of 5618 cord blood units (CBU) were screened for microbial contamination under routine conditions. The antibiotic resistance profile for all isolates was also examined using ATB strips. The detection rate for culture positive units was 7.

Palleronia abyssalis sp. nov., isolated from the deep Mediterranean Sea and the emended description of the genus Palleronia and of the species Palleronia marisminoris.

Three strains designated 221-F1(T), 221-F2 and 3030-F1 were isolated from the Matapan Vavilov Deep canyon, also known as Calypso Deep in the Eastern Mediterranean Sea, at a depth of 4,908 m. Based on 16S rRNA gene sequence analysis these strains were found to be most closely related to Palleronia marisminoris and Hwanghaeicola aestuarii, with 16S rRNA gene pairwise sequence similarity of 95.3 and 94.

Halorhabdus tiamatea: proteogenomics and glycosidase activity measurements identify the first cultivated euryarchaeon from a deep-sea anoxic brine lake as potential polysaccharide degrader.

Euryarchaea from the genus Halorhabdus have been found in hypersaline habitats worldwide, yet are represented by only two isolates: Halorhabdus utahensis AX-2(T) from the shallow Great Salt Lake of Utah, and Halorhabdus tiamatea SARL4B(T) from the Shaban deep-sea hypersaline anoxic lake (DHAL) in the Red Sea. We sequenced the H. tiamatea genome to elucidate its niche adaptations.

Natrinema salaciae sp. nov., a halophilic archaeon isolated from the deep, hypersaline anoxic Lake Medee in the Eastern Mediterranean Sea.

Two halophilic archaea, strains MDB25(T) and MDB20, were isolated from a sample of the brine from Lake Medee, at a depth of 3050 m, in the Mediterranean Sea. Cells of the organisms were Gram-negative, non-motile and pleomorphic, and colonies were red pigmented. Strains MDB25(T) and MDB20 showed optimum growth at 45°C, in 2.

Description of Idiomarina insulisalsae sp. nov., isolated from the soil of a sea salt evaporation pond, proposal to transfer the species of the genus Pseudidiomarina to the genus Idiomarina and emended description of the genus Idiomarina.

A halophilic, aerobic Gram-negative bacterium, designated strain CVS-6(T), was isolated from a sea salt evaporation pond on the Island of Sal in the Cape Verde Archipelago. Phylogenetic analysis of the 16S rRNA gene sequence revealed a clear affiliation of the organism with members of the family Idiomarinaceae. Sequence similarities between CVS-6(T) and the type strains of the species of the genera Pseudidiomarina and Idiomarina ranged from 93.

A new lineage of halophilic, wall-less, contractile bacteria from a brine-filled deep of the Red Sea.

A novel strictly anaerobic bacterium designated strain SSD-17B(T) was isolated from the hypersaline brine-sediment interface of the Shaban Deep, Red Sea. Cells were pleomorphic but usually consisted of a central coccoid body with one or two "tentacle-like" protrusions. These protrusions actively alternated between a straight, relaxed form and a contracted, corkscrew-like one.

Bacillus isabeliae sp. nov., a halophilic bacterium isolated from a sea salt evaporation pond.

A low-G+C, Gram-positive isolate, designated strain CVS-8(T), was isolated from a sea salt evaporation pond on the Island of Sal in the Cape Verde Archipelago. This organism was found to be a catalase- and oxidase-positive, non-motile, spore-forming, aerobic, curved rod-shaped organism with an optimum growth temperature of about 35-37 degrees C and an optimum pH between 7.5 and 8.

Halorhabdus tiamatea sp. nov., a non-pigmented, extremely halophilic archaeon from a deep-sea, hypersaline anoxic basin of the Red Sea, and emended description of the genus Halorhabdus.

An extremely halophilic archaeon was isolated from a sample of the brine-sediment interface of the Shaban Deep in the northern Red Sea. Phylogenetic analysis of the 16S rRNA gene sequence revealed a close proximity to Halorhabdus utahensis (99.3%), the sole species of the genus Halorhabdus.

Salirhabdus euzebyi gen. nov., sp. nov., a Gram-positive, halotolerant bacterium isolated from a sea salt evaporation pond.

A low-G+C, Gram-positive bacterium, designated CVS-14(T), was recovered from a sea salt evaporation pond on the island of Sal in the Cape Verde Archipelago. This organism was catalase- and oxidase-positive. Cells were motile, spore-forming aerobic rods, with an optimum growth temperature of about 35-40 degrees C and optimum pH between 7.
