Inducing Meningococcal Meningitis Serogroup C in Mice via Intracisternal Delivery10:03

Inducing Meningococcal Meningitis Serogroup C in Mice via Intracisternal Delivery

7.6K
Here, we describe a method to induce meningococcal meningitis through an intracisternal route of infection in adult mice. We present a step by step protocol of meningococcal infection from the preparation of inoculum to the intracisternal infection; then record the animal survival and evaluate the bacterial loads in murine...

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.
Percentiles are a type of fractile that partition data into...

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

Pneumonia I: Introduction

760
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Area of Science:

  • Infectious Diseases
  • Pulmonary Medicine
  • Bacteriology

Background:

  • Neisseria meningitidis commonly causes meningitis but is also a frequent cause of pneumonia.
  • Meningococcal pneumonia represents the most common non-neurological manifestation of this pathogen.

Purpose of the Study:

  • To review the literature on meningococcal pneumonia.
  • To describe risk factors, pathogenesis, clinical presentation, diagnosis, treatment, and prevention strategies.

Main Methods:

  • Literature review of case series and case reports.
  • Analysis of clinical features, diagnostic methods, and treatment outcomes.

Main Results:

  • Meningococcal pneumonia, associated with serogroups Y, W-135, and B, occurs in 5-10% of meningococcal infections.
  • Risk factors include older age, smoking, close contact, prior infections, and immunodeficiencies.
  • Fever, chills, and pleuritic chest pain are common symptoms; diagnosis relies on culture, with PCR showing future potential.

Conclusions:

  • Meningococcal pneumonia is a significant clinical consideration.
  • Early recognition and treatment are crucial, especially in at-risk populations.
