Helicobacter Pylori its pathogenicity, virulence and treatment
Characteristics of Helicobacter genus i) These bacteria are classified as Gram-negative organisms. ii) They exhibit a helical, curved, or straight unbranched morphology. iii) Their distinctive mode of rapid motility is achieved through the presence of sheathed flagella, which can be located at either one or both ends of the cell. iv) these bacteria produce an external glycocalyx when cultured in liquid environments. v) Notably, their major fatty acid profiles do not contain hexadecanoic acids. vi) These bacteria exhibit optimal growth at 37°C, with varying growth rates observed between 30-42°C. vii) They are microaerophilic, indicating a preference for low oxygen levels in their environment. viii) These organisms are susceptible to several antibiotics, including penicillin, ampicillin, amoxicillin, erythromycin, gentamicin, kanamycin, rifampin, and tetracycline. However, they show resistance to nalidixic acid, cephalothin, metronidazole, and polymyxin. ix) The chromo...
