A Gram-negative, non-motile, aerobic bacterium, designated
strain IP7T, was isolated from seawater at the shore of the
Incheon Eulwang-ri beach, South Korea. Cells of strain IP7T
are straight or slightly rod-shaped and colonies are round,
convex and orange-yellow. Strain IP7T is flexirubin-negative,
mild halophile, catalase- and oxidase-positive, and produces
a yellow-orange carotenoid pigment. Growth is optimal
at 30°C, pH 7–9, and 2.0–4.0% NaCl (w/v). On the basis
of 16S rRNA gene sequence similarity, strain IP7T is affiliated
with genus Aestuariibaculum in the family Flavobacteriaceae,
the closest relative being Aestuariibaculum suncheonense
SC17T (98.3% sequence similarity). The DNA G + C
content of the novel strain is 37.4 mol%. The only quinone is
MK-6 menaquinone. Iso-branched C15:0, iso-branched C15:1
G, and iso-branched C17:0 3-OH are major fatty acids. The
major polar lipids are phosphatidylethanolamine, an unidentified
aminoglycolipid and two unidentified glycolipids.
The DNA-DNA hybridization value of strain IP7T with Aestuariibaculum
suncheonense SC17T is 28.87%. Based on the collective
DNA-DNA hybridization, biochemical, phylogenetic
and physiological data, we report a novel species of the genus
Aestuariibaculum for which the name Aestuariibaculum marinum
sp. nov. is proposed. The type strain is IP7T (= KCTC
52521T = JCM 31725T).

Abstract
PDF
-
Cervical cancer is strongly associated with chronic human
papillomavirus infections, among which HPV16 is the most
common. Two commercial HPV vaccines, Gardasil and
Cervarix are effective for preventing HPV infection, but cannot
be used to treat existing HPV infections. Previously, we
developed a human endogenous retrovirus (HERV)-enveloped
recombinant baculovirus capable of delivering the L1
genes of HPV types 16, 18, and 58 (AcHERV-HP16/18/58L1,
AcHERV-HPV). Intramuscular administration of AcHERVHPV
vaccines induced a strong cellular immune response
as well as a humoral immune response. In this study, to examine
the therapeutic effect of AcHERV-HPV in a mouse
model, we established an HPV16 L1 expressing tumor cell
line. Compared to Cervarix, immunization with AcHERVHPV
greatly enhanced HPV16 L1-specific cytotoxic T lymphocytes
(CTL) in C57BL/6 mice. Although vaccination
could not remove preexisting tumors, strong CTL activity
retarded the growth of inoculated tumor cells. These results
indicate that AcHERV-HPV could serve as a potential therapeutic
DNA vaccine against concurrent infection with HPV
16, 18, and 58.

Abstract
PDF

Studies of the retroviruses have focused on the specific interaction
of the nucleocapsid protein with a packaging signal
in the viral RNA as important for this selectivity, but the
packaging signal in porcine endogenous retrovirus (PERV)
has not been defined. Herein, we identified and analyzed
this packaging signal in PERV and found hairpin structures
with conserved tetranucleotides in their loops and nucleocapsid
recognition sequences; both of which are key elements
in the viral packaging signal of MLV. We evaluated packaging
efficiency of sequence variants isolated from viral and
proviral integrated genomes. All viral packaging sequences
(Ψ) were identical, while five distinct packaging sequences
were identified from proviral sources. One proviral sequence
(Ψ1) was identical to that of the viral Ψ and had the highest
packaging efficiency. Three variants (Ψ2, Ψ3, Ψ4) maintained
key elements of the viral packaging signal, but had nucleotide
replacements and consequently demonstrated reduced
packaging efficiency. Despite of the same overall hairpin
structure, the proviral variant (Ψ5) had only one GACG sequence
in the hairpin loop and showed the lowest packaging
efficiency other than ΔΨ, in which the essential packaging
sequence was removed. This result, thus, defined the
packaging sequences in PERV and emphasized the importance
of nucleotide sequence and RNA structure in the determination
of packaging efficiency. In addition, we demonstrate
efficient infection and gene expression from the PERVbased
viral vector, which may serve as a novel alternative to
current retroviral expression systems.
