Klinker, a Samuel J. Borgert, a Brittany M. Butler, b Kenneth H. Rand, b and Nicole M. Iovine b G. V. Doern, Editor These results suggest dissemination of this clonal complex among low-risk patients. Neisseria gonorrhoeae, also known as gonococcus (singular), or gonococci (plural), is a species of Gram-negative diplococci bacteria isolated by Albert Neisser in 1879. Chocolate agar is used for growing fastidious respiratory bacteria, such as Haemophilus influenzae and Neisseria meningitidis. After failing to grow on standard and selective media, Neisseria meningitidis was identified by 16s PCR and subsequently typed as serogroup C. n. meningitidis, however, tends to undergo rapid autolysis in stationary … The interpretations of the sputum smear corre-lated well with the results of culture for meningo-cocci. [Detection of Neisseria meningitidis in pharyngeal exudates using a new culture media: agar N.M.8]. Ready-to-use QC organisms recommended for use in performance testing of media, stains, reagents and identification kits, and for the evaluation of bacteriological procedures. It is perhaps surprising that n. meningitidis colonies on blood agar are grayish, nonhemolytic, round, convex, smooth, moist, and glistening with a clearly defined edge. During an epidemic (a situation that is more common outside of the United States), secondary attack rates in family members may be as high as 4% to 5%. the organism grows on different media such as blood agar, trypticase soy agar, supplemented chocolate agar, and mueller-hinton agar.

Key words: Neisseria meningitidis, culture medium, vaccine, polysaccharide, batch cultivation INTRODUCTION Meningococcal disease is the major cause of death and morbidity throughout the world. Neisseria meningitidis, often referred to as meningococcus, is a Gram-negative bacterium that can cause meningitis and other forms of meningococcal disease such as meningococcemia, a life-threatening sepsis. NHBA is a surface-exposed lipoprotein expressed by all N. meningitidis strains in different isoforms. Three cases of infection with N.meningitidis serogroup W135 were reported in China . Neisseria meningitidis is responsible for one third of all bacterial meningitis cases in the planet. MICROBIOLOGY Aerobic, Gram-negative diplococcus Member of Neisseriaceae family, the organism has catalase and oxidase activity. Neisseria meningitidis colonizes the nasopharynx of humans, and pathogenic strains can disseminate into the bloodstream, causing septicemia and meningitis. The effects of charcoal impregnation of swabs, temperature, and an enriched CO2 atmosphere were examined with holding for up to 21 days. Polysaccharide production in batch process of Neisseria meningitidis serogroup C comparing Frantz, modified Frantz and Cartlin 6 cultivation media. Algorithm for culture and identification of Neisseria gonorrhoeae Media and cultural conditions for isolation: The primary specimens should be inoculated onto nonselective chocolate agar and selective agar containing antimicrobial agents that inhibit the growth of commensal bacteria and fungi. DISCUSSION. Neisseria meningitidis Laboratory diagnosis: Specimens: Blood, CSF, punctured material from petechiae, nasopharyngeal culture for carrier state Direct microscopic examination: Gram stained (methylene blue) smears from CSF, punctured material Antigen detection: In CSF Culture: Blood Blood culture media Onewasfromthethroatofa healthy volunteer and five were donated by the Standards Laboratory for Serological Reagents, Colindale. Other locations of invasive disease with Neisseria meningitidis are possible though rare, such as orbital cellulitis, septic arthritis, and pericarditis. N. meningitidis are gram-negative, coffee-bean shaped diplococci that may occur intracellularly or extracellularly in PMN leukocytes. The pathogen can be cultured in vitro on various media, for example, blood agar, and Mueller-Hinton agar. meningitidis is a leading cause of sepsis and meningitis, whereas N. gonorrhoeae (gonococcus) traditionally causes gonorrhea, a sexually transmitted infection involving the genitals, rectum, and throat. This manual summarizes laboratory techniques used in the isolation and identification and characterization of Neisseria meningitidis (the meningococcus), Streptococcus pneumoniae (the pneumococcus) and Haemophilus influenzae from the cerebrospinal fluid or blood of patients with clinical meningitis or bacteremia. ; Grows in blood or chocolate agar or selective media, e.g., Thayer Martin, Martin-Lewis or NY City culture media. [Europe PMC free article] [Google Scholar] ⇒ There are various culture media used for the cultivation of N. meningitidis (Meningococcus) in the laboratory and most commonly the Blood Agar and MHA medium is used, the other media are as follows - Sheep Blood Agar medium Columbia Horse Blood Agar medium Chocolate agar medium We demonstrate by using whole-genome sequencing orogenital transmission of a N. meningitidis sequence type 11 isolate causing urethritis in a monogamous couple of men who have sex with men.
