During the recent decade, uncultured bacteria have been special interest as potential candidates for discovering novel antibacterial compounds. Two strains C101 and C102 were negative Gram bacteria, only growing on low nutrient media as R2A/3, NB/3, LB/10 and R4/10 compared to the usual.

The marine environmental conditions are particularly different from terrestrial ones; recent studies have showed that marine actinomycetes might produce many novel compounds with good biological activity. The objective of this study is to isolate and screen actinomycetes strains from the marine environment with activity against pathogenic microorganisms.

The family Echinostomatidae includes four genera, Echinostoma, Hypoderaeum, Echinoparyphium, and Artyfechinostomum, which are of public epidemiological and pathogenic importance. The morphological similarity of species requires differentiating methods, and the use of molecular genetic markers is mainly encountered.

Mục tiêu của nghiên cứu là phát hiện sự lưu hành, mức độ kháng kháng sinh (KKS) của S. aureus và Streptococcus sp. phân lập từ lợn ở huyện Sơn Tịnh, tỉnh Quảng Ngãi. Các chủng S. aureus và Streptococcus sp. được định danh bằng phương pháp PCR khuếch đại gene 16S rRNA và gdh. Mức độ KKS của các chủng vi khuẩn phân lập được đánh giá bằng phương pháp khuếch tán trên đĩa thạch.

The bacteria capable of fixing atmospheric nitrogen were isolated from cassava cultivated soils of Vietnam. The potential isolates were identified by analyzing the 16S rRNA gene and by morphological, biochemical, cultural characteristics. The selected isolates were assigned to the species Bacillus sp. DQT2 M17, Bacillus subtilis DTAN6 M17, and Bacillus megaterium DSHB I8.

Bacterial infections have a substantial impact on global health and can become serious if misdiagnosed with several diseases related to the central nervous, cardiovascular, and respiratory systems. The prognosis in patients with infectious disease strongly depends on early diagnosis and appropriate antibiotic therapy.

Mussels of the genus Mytilus present morphologically similar karyotypes that are presumably conserved. The absence of chromosome painting probes in bivalves makes difficult verifying this hypothesis. In this context, we comparatively mapped ribosomal RNA and histone gene families on the chromosomes of Mytilus edulis, M. galloprovincialis, M. trossulus and M. californianus by fluorescent in situ hybridization (FISH).

Lactic acid, which can be produced by many bacterial groups through fermentation, is an interesting compound because it can be used in various fields such as in the food, pharmaceutical, material and chemical industries. In the present study, eight high lactic acid producing bacteria were isolated and screened from fermented mustard greens. The highest lactic acid producer (strain V156) was selected for further studies.

A new species Pseudocercospora solanicola is discovered causing severe leaf spot disease on Solanum nigrum from Sonebhadra. Species is described and illustrated based on morphology, molecular sequence analysis and phylogeny of the large subunit (LSU) and internal transcribed spacer region of the nuclear ribosomal RNA (rRNA) gene. Morphologically, new species has similarity with allied species in Pseudocercospora but differs in having black circular, velvety leaf spot and size of stromata, conidia and conidiophores. A key to Pseudocercospora species on Solanum has been provided.

Inocybe viscida sp. nov., a novel species found in a forest with old trees of Pinus brutia and tertiary relict endemic Liquidambar orientalis in coastal area of southwestern Turkey, is described and illustrated. We present this new species based on morphological and molecular data from nuclear rDNA internal transcribed spacer region (ITS1-5.8SITS2 = ITS) and the portions of nuc 28S rRNA (LSU) gene. Comprehensive description, field photographs, line drawings of the microscopic features and comparisons with phenetically similar taxa and phylogenetically related species are discussed.

Accumulating evidence shows that gut microbial dysbiosis may represent a risk factor for Parkinson’s disease (PD). Exercise has a positive effect on microbiota in general. The effect of aerobic exercise training (AET) on the gut microbial environment in PD remains to be explored. Here, we performed the 16S rRNA gene sequencing on feces from sham operated-mice (sham), PD mice model, and mice receiving AET (AET).

Marker gene surveys have a wide variety of applications in species identification, population genetics, and molecular epidemiology. As these methods expand to new types of organisms and additional markers beyond 16S and 18S rRNA genes, comprehensive databases are a critical requirement for proper analysis of these data.
