Negative for catalase test ''Campylobacter jejuni'' is positive for catalase test. Negative for nitrate reduction test ''Campylobacter jejuni'' is positive for nitrate reduction test. Negative for oxidase test ''Campylobacter jejuni'' is positive for oxidase test. Immotile on wet mount ''Campylobacter jejuni'' contains polar flagella and is motile on wet mount. ''Campylobacter jejuni'' is a curved, helical-shaped, non-spore forming, non-glucose-fermenting, microaerophilic, gram-negative bacteria. It is one of the most common causes of human gastroenteritis worldwide. Infection with ''C. jejuni'' occurs following invasion of the microorganism of the colonic mucosa with disruption of epithelial cells. ''C. jejuni'' has also been associated with subsequent development of Guillain-Barré syndrome, which usually develops two to three weeks after the initial illness. ''C. jejuni'' is commonly associated with ingestion of poultry as it naturally colonizes the digestive tract of many bird species. ''C. jejuni'' is grown on specially selective agar plates at 42°C, the normal avian body temperature, rather than at 37°C, the temperature at which the majority of other pathogenic bacteria are grown. Since the colonies are oxidase positive, they will usually only grow in scanty amounts on the plates. Microaerophilic conditions are required for abundant growth. A selective blood agar medium (Skirrow's medium) may also be used. The following include the mportant oxidase-positive pathogens:<br> *''Campylobacter'' *''Helicobacter'' *''Legionella'' *''Neisseria'' *''Pseudomonas'' *''Vibrio''<br/> '''Educational Objective:''' ''Campylobacter jejuni'' is a curved, helical-shaped, non-spore forming, non-glucose-fermenting, microaerophilic, gram-negative bacteria.
