Metagenomic analysis between free-living and cultured Epinephelus fuscoguttatus under different environmental conditions in Indonesian waters.

In this study, we analyzed and compared feces of free-living and cultivated fish species, Epinephelus fuscoguttatus under different environmental conditions in Indonesian waters. Metagenome analysis was performed using Illumina MiSeq sequencing of the whole metagenomic DNA isolated from fish feces samples. The analysis covered both prokaryotic and eukaryotic DNA.

Microbiome analysis and detection of pathogenic bacteria of Penaeus monodon from Jakarta Bay and Bali.

Penaeus monodon, the Asian black tiger shrimp is one of the most widely consumed marine crustaceans worldwide. In this study, we examine and compare the fecal microbiota of P. monodon from highly polluted waters around Jakarta Bay, with those of less polluted waters of Bali.

Microbial Diversity and Parasitic Load in Tropical Fish of Different Environmental Conditions.

In this study we analysed fecal bacterial communities and parasites of three important Indonesian fish species, Epinephelus fuscoguttatus, Epinephelus sexfasciatus and Atule mate. We then compared the biodiversity of bacterial communities and parasites of these three fish species collected in highly polluted Jakarta Bay with those collected in less polluted Indonesian areas of Cilacap (E. sexfasciatus, A.

Population structure of the Indonesian giant tiger shrimp Penaeus monodon: a window into evolutionary similarities between paralogous mitochondrial DNA sequences and their genomes.

Here we used both microsatellites and mtCR (mitochondrial DNA control region) sequences as genetic markers to examine the genetic diversity and population structure of Penaeus monodon shrimp from six Indonesian regions. The microsatellite data showed that shrimp from the Indian and the Pacific Ocean were genetically distinct from each other. It has been reported previously that P.

Expression of the toxin-antitoxin genes yefM(Lrh), yoeB(Lrh) in human Lactobacillus rhamnosus isolates.

Lactobacilli are important microorganisms in various activities, for example, diary products, meat ripening, bread and pickles, but, moreover, are associated directly with human skin and cavities (e.g., mouth, gut, or vagina).

Paralogous mitochondrial control region in the giant tiger shrimp, Penaeus monodon (F.) affects population genetics inference: A cautionary tale.

The mitochondrial control region (mtCR) is a widely used genetic marker for phylogenetic, phylogeographic and population genetic inference. The analysis of mtCR in 115 Indonesian specimens of the giant tiger shrimp, Penaeus monodon, revealed 26 individuals yielding a second - apparently paralogous - sequence in addition to the putatively authentic mitochondrial haplotype. The paralogous haplotypes fell into two major haplogroups that are highly diverged with respect to the authentic mitochondrial haplotypes (average pairwise sequence divergence of 12.

Fast short-fragment PCR for rapid and sensitive detection of shrimp viruses.

This article describes a fast short-fragment PCR method for the detection of white spot syndrome virus (WSSV), infectious hypodermal and hematopoietic necrosis virus (IHHNV), and monodon baculovirus (MBV). Fast two-temperature (95 degrees C denaturation and 60 degrees C annealing/extension) PCRs were performed in 5-10 microl volume samples in miniaturized microplates using a fast Peltier thermal cycler. 40 cycles were completed in 25-30 min.

Two-laser, large-field hyperspectral microarray scanner for the analysis of multicolor microarrays.

We describe the development and operation of a two-laser, large-field hyperspectral scanner for analysis of multicolor genotyping microarrays. In contrast to confocal microarray scanners, in which wavelength selectivity is obtained by positioning band-pass filters in front of a photomultiplier detector, hyperspectral microarray scanners collect the complete visible emission spectrum from the labeled microarrays. Hyperspectral scanning permits discrimination of multiple spectrally overlapping fluorescent labels with minimal use of optical filters, thus offering important advantages over standard filter-based multicolor microarray scanners.
