    Insights

    A nosocomial infection outbreak caused by Klebsiella aerogenes in a surgical ward was traced to contaminated washing-bowls. Implementing individual, disinfected, and properly stored bowls can prevent future hospital-acquired infections.

    Area of Science:

    • Infectious Diseases
    • Hospital Epidemiology
    • Microbiology

    Background:

    • Nosocomial infections pose a significant threat in healthcare settings.
    • Klebsiella aerogenes is an opportunistic pathogen that can cause hospital-acquired infections.
    • Surgical wards are particularly vulnerable to outbreaks due to patient susceptibility.

    Purpose of the Study:

    • To describe an episode of Klebsiella aerogenes nosocomial infection in a surgical ward.
    • To identify the source and transmission route of the outbreak.
    • To recommend preventive measures against future outbreaks.

    Main Methods:

    • Case investigation of infected patients.
    • Environmental sampling and analysis of washing-bowls.
    • Microbiological identification of Klebsiella aerogenes.

    Main Results:

    • Six patients in the surgical ward were infected with Klebsiella aerogenes.
    • Contaminated washing-bowls were identified as the source of the outbreak.
    • The transmission was linked to the shared use and inadequate disinfection of washing-bowls.

    Conclusions:

    • Contaminated washing-bowls are a potential source of Klebsiella aerogenes transmission in hospitals.
    • Strict hygiene protocols, including individual patient bowls, are crucial for infection control.
    • Proper disinfection, drying, and storage of patient-use items are essential to prevent nosocomial infections.

    Bacterial Flora of the Large Intestine01:29

    Bacterial Flora of the Large Intestine

    The gut microbiome is formed by a vast and diverse community of bacteria that colonizes our large intestine. These bacteria start residing in the gut from birth and continue diversifying throughout life, influenced by factors such as diet, lifestyle, and stress. The gut bacterial community also includes bacteria from food and those that enter the colon through the anus.
    The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.

    Anatomy of the Intestines

    Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
    Small Intestines
    The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

    Chronic Bowel Disorders: Introduction

    Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
    Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

    Irritable Bowel Syndrome I: Introduction

    Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
    IBS is a chronic condition that can persist over a long period or recur frequently.
    The pathogenesis of IBS involves a complex interplay of the following factors:

    Physiology of the Gastrointestinal System III: Elimination

    The gastrointestinal elimination process involves a complex interplay of neural and hormonal mechanisms that coordinate the final waste removal from the body. This intricate operation encompasses the absorption of water and electrolytes, vital for transforming the remaining indigestible food matter into feces. The large intestine is pivotal in water and electrolyte absorption, forming feces from unabsorbed minerals, undigested food, bacteria, bile pigments, and shed epithelial cells. Essential...

    Inflammatory Bowel Disease I: Ulcerative Colitis

    Introduction
    Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
    Risk Factors
    The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
