    Insights

    Plesiomonas shigelloides is a rare cause of invasive infections, often linked to the gastrointestinal tract. This case highlights its role as an opportunistic pathogen in patients with compromised immunity and liver disease.

    Area of Science:

    • Microbiology
    • Infectious Diseases
    • Clinical Medicine

    Background:

    • Plesiomonas shigelloides is typically associated with gastrointestinal infections in humans and animals.
    • Recent findings suggest an emerging role of this bacterium in opportunistic infections.
    • Patients with underlying conditions, such as liver disease, may be more susceptible to invasive infections.

    Purpose of the Study:

    • To report a case of Plesiomonas shigelloides septicaemia and pleural effusion.
    • To illustrate the potential of P. shigelloides as an opportunistic pathogen in immunocompromised individuals.
    • To emphasize the significance of P. shigelloides in patients with co-existing alcoholic liver disease.

    Main Methods:

    • Case report of a patient with alcoholic liver disease.
    • Clinical presentation and diagnostic findings of Plesiomonas shigelloides infection.
    • Review of literature on P. shigelloides as an opportunistic pathogen.

    Main Results:

    • The patient presented with septicaemia and pleural effusion.
    • Plesiomonas shigelloides was identified as the causative agent.
    • The infection occurred in a patient with pre-existing alcoholic liver disease, indicating a compromised host.

    Conclusions:

    • Plesiomonas shigelloides can cause severe invasive infections, including septicaemia and pleural effusion.
    • Patients with alcoholic liver disease are at increased risk for opportunistic infections by P. shigelloides.
    • This case underscores the importance of considering P. shigelloides in the differential diagnosis of infections in immunocompromised patients, particularly those with liver disease.

    Pneumonia I: Introduction01:30

    Pneumonia I: Introduction

    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...

    Pleural Effusion I: Introduction01:25

    Pleural Effusion I: Introduction

    Pleural effusion is an abnormal fluid accumulation in the pleural cavity, a narrow space between the lungs and the chest wall. It is not a disease per se but rather a symptom or indication of an underlying disease. In normal circumstances, this space contains a small amount of fluid (5 to 15 mL), a lubricant facilitating the non-frictional movement of the pleural surfaces.
    There are two main types of pleural effusion: transudative and exudative. They are differentiated using Light's criteria,...

    Pleural Effusion II: Symptoms and Management

    Pleural Effusion Overview
    A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
    Clinical Manifestations:
    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...
