First case of CAPD-related peritonitis caused by Morganella morganii

Insights

Morganella morganii, a Gram-negative bacillus, rarely causes peritonitis. This case highlights a patient undergoing continuous ambulatory peritoneal dialysis (CAPD) with this infection.

Area of Science:

  • Medical Microbiology
  • Infectious Diseases
  • Nephrology

Background:

  • Peritonitis is a serious complication in patients undergoing peritoneal dialysis.
  • Gram-negative bacilli are infrequent causes of peritonitis in this population.

Observation:

  • A 55-year-old female patient on continuous ambulatory peritoneal dialysis (CAPD) presented with peritonitis.
  • The causative agent was identified as Morganella morganii.

Findings:

  • Morganella morganii, a Gram-negative bacillus, was confirmed as the pathogen responsible for the peritonitis.
  • This represents a rare instance of this bacterium causing peritoneal infection in a CAPD patient.

Implications:

  • This case underscores the importance of considering a broader spectrum of pathogens, including rare ones like Morganella morganii, in CAPD-associated peritonitis.
  • Prompt and accurate identification of the causative agent is crucial for effective treatment and management of peritonitis in dialysis patients.

Bacterial Meningitis01:24

Bacterial Meningitis

Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...

Bacterial Meningitis I: Introduction

Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
Pneumonia I: Introduction01:29

Pneumonia I: Introduction

Pneumonia is an infection of the lower respiratory tract that leads to inflammation of the lung parenchyma, often resulting in the accumulation of inflammatory exudate in the alveoli and airways. Unlike the watery, low-protein fluid exudate in pulmonary edema, the exudate in this case is a thick fluid rich in immune cells, proteins, and debris produced during infection and inflammation.This impairs gas exchange and can lead to consolidation of lung tissue. The infection may be caused by a...
Atypical Pneumonia01:14

Atypical Pneumonia

Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
