Abstract. The Gram-negative bacteria genus Neisseria includes both pathogenic and commensal species that are found primarily in the upper respiratory tract of humans and animals. The development of animal models to study neisserial pathogenesis has focused almost exclusively on two species that cause disease in humans.Click to see full answer. Besides, where is Neisseria found?Many normal individuals may harbor Neisseria meningitidis in the upper respiratory tract, but Neisseria gonorrhoeae is never part of the normal flora and is only found after sexual contact with an infected person (or direct contact, in the case of infections in the newborn). where are Neisseria found as normal flora? Neisseria are aerobic gram-negative diplococci belonging to the family Neisseriaceae, which mainly colonize the human oral cavity and nasopharynx. Most Neisseria are members of the normal microflora of the human body and are usually nonpathogenic. where is Neisseria meningitidis normally found in the body? N. meningitidis is a part of the normal nonpathogenic flora in the nasopharynx of up to 5–15% of adults. It colonizes and infects only humans, and has never been isolated from other animals.How do you identify Neisseria?N. meningitidis can be identified using Kovac’s oxidase test and carbohydrate utilization. If the oxidase test is positive, carbohydrate utilization testing should be performed. If the carbohydrate utilization test indicates that the isolate may be N.
