Antibiotic resistance in Neisseria meningitidis Penicillin has long been recognized as the antibiotic of choice for treatment of meningococcal infections, but clinicians have recently become concerned about the susceptibility of meningococci to penicillin and other antibiotics used in the management of meningococcal disease
  2. MICROBIOLOGY Neisseria meningitidis (the meningococcus) is a fastidious Gram-negative diplococcus that colonizes and invades only man. In genetic terms, its closest relative is the gonococcus, Neisseria gonorrhoeae. The entire genetic sequences of a serogroup A and a serogroup B meningococcus have been published
  3. Meningococcal disease is a contagious bacterial disease caused by the bacteria Neisseria meningitidis (N meningitidis) with high fatality rates: up to 15% for infection of the central nervous system (meningitis) and up to 50% to 60% among patients with blood stream infection and shock; up to 15% of survivors are left with severe neurological deficits
  4. Neisseria meningitidis (Nm, the meningococcus) is a leading cause of bacterial meningitis throughout the world. Besides meningitis, meningococci can cause sepsis, pneumonia and, occasionally, focal infections such as arthritis, myocarditis, pericarditis, endophthalmitis, epiglottitis, otitis and urethritis
  5. Neisseria meningitidis(the meningococcus) causes significant morbidity and mortality in children and young adults worldwide through epidemic or sporadic meningitis and/or septicemia. In this review, we describe the biology, microbiology, and epidemiology of this exclusive human pathogen

Neisseria meningitidis is a gram-negative diplococci (spheres clumped in pairs) bacteria. Meningitis and septicemia constitute the majority of cases of meningococcal disease. Other illnesses include septic arthritis, pneumonia, and rarely pericarditis. Only cases of invasive meningococcal disease (sterile site) are reportable and require a contact investigation Historically, N. meningitidis isolates in the United States have largely been susceptible to the antibiotics recommended for treatment and prophylaxis, including penicillin and ciprofloxacin. This report describes detection of penicillin-resistant and ciprofloxacin-resistant N. meningitidis serogroup Y (NmY) isolates in the United States Antibiotic-resistant Neisseria meningitidis Serogroup Y CDC recently reported multiple cases of β-lactamase-producing N. meningitidis serogroup Y in the United States, including eleven cases also resistant to ciprofloxacin Neisseria meningitidis (N. meningitidis) was first discovered in 1887 by Weichselbaum from analyzing the cerebrospinal fluid (CSF) of a patient infected with meningitis.[1] It is a human-specific bacterium that causes a multitude of illnesses, collectively termed meningococcal disease. Surprisingly, up to 10% of the general population carry the bacteria in their nose and throat without any.

Neisseria meningitidis is a gram-negative diplococcus that is closely related to the gonococcus. It causes a spectrum of disease, ranging from transient fever and bacteremia to menin-gitis and fulminant septicemia. For many years penicillin has been recognized as the antibiotic of choice for meningococca The most recent MMWR included a report about a novel, emerging strain of beta-lactamase-producing Neisseria meningitidis in the United States that is resistant to both penicillin and ciprofloxacin Neisseria meningitidis is a Gram-negative diplococci with 13 distinct serotypes. It inhabits the mucosal surface of nasopharynx and oropharynx [].However, about 90% of human disease are caused by serogroup A, B, C, X, Y, and W135 [].About 5-10% of healthy people carry N. meningitidis in the nasopharynx and oropharynx and during epidemics, the carrier state rises to 70-80% [] harbor strains of Neisseria meningitidis, especially during winter months. Less than 1% of persons harboring strains of Neisseria meningitidis develop invasive disease. In the absence of exposure to a person with invasive meningococcal infection, persons with pharyngeal colonization do not require antibiotic therapy

Once the organism is identified as N meningitidis, patients are typically treated with penicillin or ampicillin, antibiotics with a narrower spectrum of activity that's less likely to lead to.. Meningococcal disease is a sudden-onset, life-threatening illness caused by the bacterium Neisseria meningitidis. Prompt antibiotic treatment can reduce morbidity and mortality among patients and antibiotic prophylaxis can prevent secondary disease in close contacts (https://redbook.solutions.aap.org/chapter.aspx?sectionid=189640131&bookid=220 Neisseria meningitidis is the most common cause of bacterial meningitis in children and is a leading cause of meningitis in adults. N. meningitidis lives harmlessly in the mucous membranes of the nose and throat of 10%-20% of human beings. These symptom-free (asymptomatic) carriers are crucial to the transmission of N 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. The bacterium is referred to as a coccus because it is round, and more specifically, a diplococcus because of its tendency to form pairs Persistence of Neisseria meningitidis in the upper respiratory tract after intravenous antibiotic therapy for systemic meningococcal disease.

N. meningitidis is spread through the exchange of respiratory and throat secretions via activities like coughing or kissing.In addition to those who are in close contact with those infected by N. meningitidis, college students living in dorms are considered at increased risk of acquiring the infection.Antibiotic prophylaxis is suggested for those who were potentially exposed to the bacterium Neonatal conjunctivitis caused by Neisseria meningitidis is a rare occurrence. Using whole-genome sequencing, we analyzed an isolate of N. meningitidis from a 3-day-old infant in New York, USA, who was given a diagnosis of unilateral conjunctivitis Pathogenic bacteria have evolved numerous mechanisms to evade the human immune system and have developed widespread resistance to traditional antibiotics. We studied the human pathogen Neisseria meningitidis and present evidence of novel mechanisms of resistance to the human antimicrobial peptide LL-37. We found that bacteria attached to host epithelial cells are resistant to 10 μM LL-37.

Neisseria gonorrhea, on the other hand, continues to develop resistance; the acquired resistance due to selective pressure generated by the use of antibiotics is considered the main element. Approximately 75 percent of cases with invasive disease have meningitis (typically causing headache, photophobia and neck stiffness). Infants present with less-specific features. Other locations of invasive disease with Neisseria meningitidis are possible though rare, such as orbital cellulitis, septic arthritis, and pericarditis

Antibiotics for preventing meningococcal infections Cochran

Meningococcal meningitis is caused by the bacteria Neisseria meningitidis (also known as meningococcus). Meningococcus is the most common cause of bacterial meningitis in children and teens. It is a leading cause of bacterial meningitis in adults. The infection occurs more often in winter or spring. It may cause local epidemics at boarding. A total of 240 samples were collected (115 from males and 125 from females). The mean age of study participants was 11.1 years. The prevalence of nasal carriage for Neisseria meningitidis was 20.4% (49/240). Carriage was significantly higher among children living under crowded conditions (OR 1.268; 95% CI: 1.186-1.355; p = 0.006) Penicillin has long been recognized as the antibiotic of choice for treatment of meningococcal infections, but clinicians have recently become concerned about the susceptibility of meningococci to penicillin and other antibiotics used in the management of meningococcal disease. Strains relatively resistant to penicillin (minimum inhibitory concentrations ranging from 0.1 mg/L to 1.28 mg/L. The Neisseria meningitidis bacterium is usually spread through close, personal or prolonged contact with respiratory or oral secretions. Unlike a cold or the flu, the bacteria that cause meningitis cannot be spread by casual contact or by breathing the air where an infected person has been Keywords: Carriage, N. meningitidis, School children, Antimicrobial susceptibility Background Neisseria meningitidis is a Gram-negative diplococci with 13 distinct serotypes.

Symptoms: Sudden onset of fever, head-ache, nausea, vomiting, lethargy, and irritability in cases of meningococcemia; headache, nausea, vomiting, and stiff neck in cases of meningitis. A petechial rash is seen frequently. Delirium and coma are not uncommon Factsheet. Meningococcal disease is caused by the bacterium Neisseria meningitidis. The bacterium is often detected in the nasopharynx without causing disease, a situation described as asymptomatic carriage. The bacteria occasionally invade the body and cause meningococcal infection, which is an acute severe bacterial infection Some antimicrobials, like vancomycin and nystatin are usually added to the Thayer-Martin agar, to inhibit the possible growth of undesired bacteria or fungi, and maximize the growth of Neisseria species. However, other Neisseria species, like N. meningitidis, have the same properties. So the maltose fermentation test is done to differentiate.

N. meningitidis is especially dangerous in young children. Typical symptoms are headache, meningeal signs, and fever. Mortality is close to 100% if untreated; less than 10% with prompt and appropriate antibiotic therapy. Effective vaccines targeting the polysaccharide capsules of major pathogenic strains (serogroups) are available Neisseria meningitidis causes meningitis in about 25 out of 100 people who get the illness every year in the United States.
