Neisseria is a large genus of bacteria that colonize the mucosal surfaces of many animals. Of the 11 species that colonize humans, only two are pathogens, N. meningitidis and N. gonorrhoeae.Most gonococcal infections are asymptomatic and self-resolving, and epidemic strains of the meningococcus may be carried in >95% of a population where systemic disease occurs at <1% prevalence Neisseria gonorrheae 1.

Neisseria meningitidis o meningococo es una bacteria Gram-negativa, oxidasa-positiva, aeróbica, que microscópicamente aparece como diplococos. Las distintas cepas se clasifican en serogrupos en función de los polisacáridos de la cápsula. Los meningococos son una de las principales causas de la meningitis meningocócica Neisseria gonorrhoeae From dc123.4shared.com - April 1, 2013 7:09 PM. CHARACTERISTICS: Neisseria spp. are gram-negative, non-motile, and non-spore-forming bacteria belonging to the family Neisseriaceae Footnote 1, Footnote 3. All members of the Neisseria spp., except the three subspecies of N. elongata and N. weaveri, occur as diplococcal bacteria with their adjacent sides flattened, resembling a kidney or coffee.
These are bacteria that define the opposite of the gram-positive bacteria in relation to the differential staining technique. During gram staining, the gram-negative bacteria will lose the crystal violet dye color after a wash with alcohol and take up the pink/red color of the counterstain, safranin..

SUMMARY The only natural reservoir of Neisseria meningitidis is the human nasopharyngeal mucosa. Depending on age, climate, country, socioeconomic status, and other factors, approximately 10% of the human population harbors meningococci in the nose. However, invasive disease is relatively rare, as it occurs only when the following conditions are fulfilled: (i) contact with a virulent strain. NEISSERIA MENINGITIDIS.

Talk to our Chatbot to narrow down your search Meningococcal meningitis, caused by Neisseria meningitidis bacteria, is of particular importance due to its potential to cause large epidemics. Twelve types of N. meningitides, called serogroups, have been identified, six of which (A, B, C, W, X and Y) can cause epidemics.. Meningococcal meningitis is observed in a range of situations, from sporadic cases, small clusters, to huge epidemics.
Gonorrhea is a sexually transmitted disease (STD) caused by Neisseria gonorrhea. It can infect mucus-secreting epithelial cells both in men and women.

Identification of Neisseria gonorrhoeae as the causative agent in a case of culture-negative dermatitis-arthritis syndrome using real-time PCR The viridans streptococci are a large group of commensal streptococcal Gram-positive bacteria species that are α-hemolytic, producing a green coloration on blood agar plates (hence the name viridans, from Latin vĭrĭdis, green). The pseudo-taxonomic term Streptococcus viridans is often used to refer to this group of species, but writers who do not like to use the pseudotaxonomic term.

Meningitis is an inflammation of the meninges, the lining surrounding the brain and the spinal cord. Public health concerns mainly focus on the bacteria *Neisseria meningitidis*, as it can cause large-scale epidemics. This course provides a general introduction to Meningitis and is intended for incident managers and personnel working for the United Nations, international organizations and NGOs One type of bacteria that infects meninges is called Neisseria meningitidis. An infection of this tissue can cause a dangerous buildup of pressure on the brain. Symptoms of infection may include
Pathogenic bacteria are bacteria that can cause disease. This article deals with human pathogenic bacteria. Although most bacteria are harmless or often beneficial, some are pathogenic, with the number of species estimated as fewer than a hundred that are seen to cause infectious diseases in humans. By contrast, several thousand species exist in the human digestive system Neisseria gonorrhoeae and Neisseria meningitidis are two important pathogens in this group. Gonorrhea is a sexually transmitted disease caused by N. gonorrhoeae and is one of the most frequently reported infectious diseases in the United States and worldwide. This organism is oxidase-positive, and growth is best obtained on Chocolate Agar or.

Meningitis is an acute inflammation of the protective membranes covering the brain and spinal cord, known collectively as the meninges.

Summary. Meningitis is a serious infection of the meninges in the brain or spinal cord that is most commonly viral or bacterial in origin, although fungal, parasitic, and noninfectious causes are also possible. Enteroviruses and herpes simplex virus are the leading causes of viral meningitis, while Neisseria meningitidis and Streptococcus pneumoniae are the pathogens most commonly responsible. A surgical site infection is an infection that occurs after surgery in the part of the body where the surgery took place. Surgical site infections can sometimes be superficial infections involving the skin only Succinate dehydrogenase (SDH) or succinate-coenzyme Q reductase (SQR) or respiratory complex II is an enzyme complex, found in many bacterial cells and in the inner mitochondrial membrane of eukaryotes.It is the only enzyme that participates in both the citric acid cycle and the electron transport chain.
