Isolation and Identification of Non-O1/Non-O139 Vibrio cholerae in Wild Birds Inhabiting Wetlands in Metropolitan Lima, Peru.

During a survey in wetlands from southern Lima, Peru, two non-O1/non-O139 Vibrio cholerae isolates were obtained from samples collected from an American Oystercatcher (Haematopus palliatus) and a Wren-like Rushbird (Phleocryptes melanops). Vibrio cholerae was identified by amplification and sequencing of 16S rRNA, differentially grown on CHROMagar Vibrio media, and confirmed by ompW amplification. Isolates were confirmed to be non-O1/non-O139 serotypes and to lack the ctxA gene as inferred using PCR. Susceptibility to eight antimicrobial agents was assessed, with one isolate being resistant to azithromycin, doxycycline, tetracycline, and furazolidone. Our results indicate the utility of surveillance for V. cholerae in wetlands in the metropolitan Lima area.

Draft Genome Sequence of Streptomyces sp. Strain PAM3C, a Prospective Probiotic Agent Isolated from the Gut of the Bay Scallop, Argopecten purpuratus (Lamarck, 1819).

Several bacterial genera with antagonistic activity against pathogenic organisms have been isolated in pure culture from the gut of the Peruvian scallop, Argopecten purpuratus. One strain shows a broad inhibitory activity against aquaculture pathogenic bacterial strains. In this communication, we announce the draft genome sequence of Streptomyces sp. strain PAM3C.

Bacterial Diversity Profiling around the Orca Seamount in the Bransfield Strait, Antarctica, Based on 16S rRNA Gene Amplicon Sequences.

Hydrothermal vent activity is often associated with submarine volcanism. Here, we investigated the presence of microorganisms related to hydrothermal activity in the Orca seamount. Data profiling of the 16S rRNA gene amplicon sequences revealed a diversity pattern dominated mainly by the phyla Proteobacteria, Acidobacteria, Planctomycetes, and Bacteroidetes.

Comparative Analysis of Gut Microbiota in Two Populations of Argopecten purpuratus (Lamarck, 1819) Based on 16S rRNA Gene Amplicon Data.

Despite the importance of the Peruvian scallop Argopecten purpuratus as a major cultivated species, information on its microbiota is limited. Here, we provide a high-throughput sequencing data analysis of 16S rRNA gene amplicons from the distal intestine of A. purpuratus Geographical and seasonal variation of the indigenous gut microbiota is shown.

Draft Genome Sequence of Streptomyces sp. Strain RFCAC02, Isolated from the Gut Microflora of the Pacific Chub Mackerel Scomber japonicus peruanus.

A new strain of Streptomyces sp., strain RFCAC02, was isolated from the gut of the Pacific chub mackerel Scomber japonicus peruanus This strain produces a variety of secondary metabolites. Further bioinformatic analysis revealed the presence of biosynthetic gene clusters putatively coding for compounds related to the polycyclic tetramate macrolactams (PTMs).

Draft Genome Sequence of a New Vibrio Strain with the Potential To Produce Bacteriocin-Like Inhibitory Substances, Isolated from the Gut Microflora of Scallop (Argopecten purpuratus).

A new Vibrio strain, V7A, was isolated from the intestinal tract of the Peruvian scallop (Argopecten purpuratus). Strain V7A clusters within the Mediterranei clade of the genus Vibrio and has the potential to produce bacteriocin-like inhibitory substances (BLIS). Here, we report the draft genome sequence of Vibrio mediterranei strain V7A.

Draft Genome Sequence of Vibrio sp. Strain V1B Isolated from the Gut Microflora of the Scallop Argopecten purpuratus.

A new Vibrio strain, V1B, was isolated from the intestinal tract of the scallop Argopecten purpuratus Strain V1B is closely related to the species Vibrio inhibens BFLP-10, which has been characterized as showing antagonistic activity against pathogenic Vibrio sp. We report here the draft genome of the isolated Vibrio sp. strain V1B.
