Clinical Characteristics of Corynebacterium ulcerans Infection, Japan
Emerging Infectious Diseases
|July 24, 2023
Summary
Corynebacterium ulcerans infections are rising in Japan, causing diphtheria-like illness. Vaccination against diphtheria toxoid is recommended for adults to prevent further spread of this emerging zoonotic pathogen.
Area of Science:
- Microbiology
- Infectious Diseases
- Public Health
Background:
- Corynebacterium ulcerans, a bacterium related to C. diphtheriae, can produce diphtheria-like toxins.
- It is an environmental pathogen affecting livestock and wildlife, increasingly recognized as a zoonotic agent.
- C. ulcerans infections cause respiratory and nonrespiratory symptoms in humans.
Purpose of the Study:
- To analyze clinical characteristics, treatment factors, and outcomes of C. ulcerans infections in Japan.
- To understand the epidemiology of C. ulcerans in the region.
- To inform public health strategies regarding this emerging pathogen.
Main Methods:
- Retrospective analysis of 34 C. ulcerans cases in Japan from 2001-2020.
- Review of clinical data, treatment interventions, and patient outcomes.
- Epidemiological analysis of incidence trends.
Main Results:
- A marked increase in C. ulcerans infection incidence was observed between 2010-2020.
- The overall mortality rate for C. ulcerans infection was 5.9%.
- The study identified key clinical features and treatment considerations.
Conclusions:
- Corynebacterium ulcerans is an emerging zoonotic pathogen causing diphtheria-like illness in Japan.
- Increased incidence and notable mortality underscore the public health significance.
- Diphtheria toxoid vaccination for adults is recommended to mitigate spread.

01:28Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies
157
Peptic ulcer disease (PUD) presents with diverse symptoms depending on the location and severity of the ulcer. Clinical manifestations of peptic ulcer include dull pain and a burning sensation in the mid-epigastric region.
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.

36
Coryneform bacteria are gram-positive, aerobic, nonmotile rods that exhibit irregular, club-shaped, or V-shaped arrangements. Their V-shape results from snapping division, where the inner cell wall layer forms the cross-wall, while the outer layer remains intact until it ruptures on one side, causing the daughter cells to bend away.The primary genera are Corynebacterium and Arthrobacter. Corynebacterium includes diverse species, ranging from saprophytes to pathogens like Corynebacterium...

01:28Peptic Ulcer Disease II: Pathophysiology
522
Peptic Ulcer Disease (PUD) is characterized by the development of ulcers in the stomach or duodenal mucosa. Its pathophysiology is complex, involving a balance between damaging and protective elements.
Damaging agents such as Helicobacter pylori, gastric acid, pepsin, and nonsteroidal anti-inflammatory drugs (NSAIDs) can weaken the mucosal defense, allowing hydrogen ions to infiltrate back and harm epithelial cells.

01:30Peptic Ulcer Disease I: Introduction
202
Peptic Ulcer Disease (PUD) is characterized by mucosal excavation in the esophagus, stomach, pylorus, or duodenum. It can manifest as acute or chronic based on the extent and duration of mucosal involvement.
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
Peptic ulcers can also be...

01:22Pathophysiology of Peptic Ulcer Disease: Injurious Factors
640
Peptic ulcers are sores on the stomach's inner lining and the upper small intestine, which are the result of disruptions in the mucosal layer that houses parietal cells which produce gastric acid, and chief cells which secrete pepsinogen.
In the antrum region, G cells secrete the gastrin hormone that binds to gastrin-cholecystokinin-B (CCK2) receptors on parietal and enterochromaffin-like (ECL) cells in the fundic glands. Simultaneously, the vagus nerve releases acetylcholine, which binds...

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
