The aim of the Natural Sciences Bibliographic Web Portal including its two new Plasmid and Pneumoniae References sections is to provide comprehensive bibliographic information on the basic and applied life, earth and health sciences. The information contains a minimum of bibliographic information consisting of title, authors, publication year and source while expanded references provide an additional summary of the publication's scientific content. All references are grouped into eleven main sections which are subdivided into ten categories each. The site as well as every section and category provides RSS feeds alerting the site's users of newly published content. Every bibliographic reference is tagged with up to twenty scientific keywords which cross-connects them beyond sections and categories.
The section Bacteria contains information on these unicellular microorganisms. Bacteria lack organelles and an organized nucleus and many of them can cause disease. The latest content in this category is also available through a Bacteria RSS feed. The section currently contains circa 8,430 posts and is subdivided into ten categories including Bacillus, Lipopolysaccharide, Muscle, Necrosis, Pathogen, Plasmid, Pneumoniae, Pseudomonas, Streptococcus and Vaginosis.
Within this section, the category Plasmid contains information on these genetic structures in a cell that can replicate independently of the chromosomes. A plasmid typically is a small circular DNA strand in the cytoplasm of a bacterium or protozoan, but are sometimes found in eukaryotic organisms. They are frequently used in the laboratory manipulation of genes. The category currently contains circa 50 posts of which the latest inclusions are also available through a Plasmid RSS feed. It features a post on purification and characterization of cryptic plasmids pLS1 and pLS2 from Erwinia chrysanthemi and one on indigenous plasmids of Pseudomonas syringae pv. mori as the causal agent of bacterial blight of mulberry. Other bibliographic resources cover characterization of Tn904 insertions in octopine Ti plasmid mutants of Agrobacterium tumefaciens, analysis of a range of crown gall and normal plant tissues for Ti plasmid-determined compounds, and that the host range of the crown gall bacterium is determined by the virulence plasmid. The latter article was published in the journal "California Plant Pathology" in 1980.
The new category Pneumoniae covers pneumonia which is an infection of the lung that can be caused by nearly any class of organism known to cause human infections. These include bacteria such as Mycoplasma pneumoniae, Streptococcus pneumoniae, Klebsiella pneumoniae and Chlamydophila pneumoniae. The category currently contains circa 410 posts of which the latest inclusions are also available through a Pneumoniae RSS feed. It features a reference covering experimental comparative bacteriological and histopathological studies on Diplococcus pneumoniae in rabbits which was published in the journal of the Egyptian Veterinary Medical Association. While another post covers a bibliographic study on the effects of pollutants on resistance to infectious diseases and immunity with special reference to experimental results with PCB, it also presents a post on isolation of Nocardia asteroides from cattle with mastitis in Sudan and enterobacteriaceae in the faeces of dogs with special reference to Yersinia enterocolitica. The article on the microflora of the gut of healthy foraging honeybees provides an inventory of their gram-negative bacterial populations.
While the publishers of the web portal have a stock of 21,238,124 references of which 10,564,269 (50%) contain a summary, this information will be made successively available to the public until 2014. While the site has presently published a total of 840,000 posts online, the number of published bibliographic resources increases by circa 20,000 items every day. This status is reflected in the site's continuously updated tagline.
