Helicobacter pylori | Description | Helicobacter pylori is a motile‚ curved‚ spiral‚ or straight‚ slightly plump‚ gram-negative rod. It is believed to be a major cause of gastritis and peptic ulcers although it resides solely on the gastric mucosa and does not enter cells.

Biology101 McDowall 10/29/2012 Escherichia Coli “The Bacterial Beast” E.coli or binomial name Escherichia coli was discovered by a German pediatrician named Theodore Escherich in 1885. Dr. Escherich originally named the bacteria‚ bacillus communis coli. After the demise of Dr. Escherich the intestinal bacteria was then named Escherichia coli after the late doctor in 1919. The bacteria Escherichia coli are classified as follows. Domain- Bacteria Kingdom- Eubacteria Phylum- Proteobacteria

economical project. In this we want to show how to reduce the harmful effects of nitrogen which gets mixed with water by natural hazard or else by man-made hazards. With the help of two types of bacteria like thiobascillus and rod shaped bacteria of bacillus species‚ we want to reduce the adverse effects of the dissolved nitrogen in the water bodies. HYPOTHESIS:- Nitrate-rich water containing denitrifying bacteria will exhibit a faster rate of reduction in nitrate levels. OBJECTIVE:- To denitrify

If bacterial meningitis is suspected several tests sound be done before beginning treatment. A blood sample should be taken and a complete blood count (CBC) should be performed and a lumbar puncture should also be performed as soon as possible. Laboratory findings The white blood cell count (WBC) should be 5‚000-10‚000 /mm3. Critical values associated WBC are 30‚000 /mm3. Variables that may increase white blood cell count include: Physical activity and stress‚ final months of pregnancy and/or labor

Identification and characterization of Pierisin gene in P. napi The strategy was followed to amplify the Pierisin-6 gene was given in the supplementary Fig. 1. The mRNA of pierisin-6 gene was purified from the total RNA of fifth instar larvae of P. napi‚ the conserved region was amplified using gene specific primers (supplementary table-1)‚ cloned into pGEM®-T vector and sequenced. Further‚ 3’ and 5’ untranslated regions of pierisin-6 gene were identified by 3’/5’ RACE-PCR. The amplified cDNA sequence

Antimicrobial activity was performed on various fractionated extracts against five pathogenic microorganisms (Bacillus subtilis‚ Staphylococcus aureus‚ klebsiella species‚ Escherichia coli and Salmonela paratyphi). The zone of inhibitions shown by Acetone soluble (PPAs) and acetone insoluble (PPAins) extract when compared to that of standard antibiotic (streptomycin)‚ in which gram positive bacteria (Bacillus subtilis and Staphylococcus aureus) were found effective in ubiquitos of samples (10%PPAs and 15%PPAins)

strains of Corynebaterium diphtheria; this agent is classified as Actinobacteria. The bacteria’s scientific name is Corynebacterium diphtheriae‚ Corynebacterium is the genus and diphtheriae is the species. The minor bacteria are non-sporulated‚ gram-positive‚ bacillus “with enlarged extremities” (Cohen & Powderly‚ 2010). With a range 0.5 to 1 µm units in diameter‚ the single strain of cells vary in size. Corynebacterium diphtheriae has fimbriae; this allows the bacteria to cling on to the hos-cell receptors
