Detailed Introduction

Helicobacter pylori are a species of epsilon proteobacteria which colonizes the harsh environment of the human stomach. Its name refers to both its spiral shape (Helicobacter) and the area of the lower stomach which it habitually colonizes: the gateway (pylorus) between the stomach and small intestine (Meyers, 2007). This bacterium is thought to be present within up to 50% of the human population and has been linked to the development of a number of different medical conditions (Chalmers et al. 2004).

Genomes of isolates from different individuals are unusual in their diversity in gene order and sequences within individual genes. 'H. heilmannii1 is another gastric spiral shaped organism less frequently infecting humans but commonly found in cat and dog gastric tissue. H. felis is important in the mouse model of infection. A range of conventional phenotypic tests as well as some new PCR based assays are available for identifying isolates of Helicobacter from clinical specimens.[11](

Chemotherapeutic Methods of Control, Treatment, and Eradication

If you are found to have Helicobacter pylori infection, you may wish to have antibiotic treatment of some kind. Treatment of Helicobacter pylori is usually simple & straight forward. However, occasional patients need repeated endoscopies, biopsies, breath tests and several courses of treatment with different antibiotic combinations. After treatment of H. pylori, it is necessary to repeat one of these tests to see if the germ has been killed or eradicated for good. Only breath tests or endoscopy with biopsy can be used to prove that the bacterium has been eradicated. The blood tests *(serology) is not suitable to monitor H.pylori eradication because antibodies to H. pylori may remain positive for months or even years after successfully
