Summary
Lactococcus garvieae, a fish pathogen, caused infective endocarditis in a Japanese woman. This rare case highlights the pathogen
Area of Science:
- Infectious Diseases
- Microbiology
Background:
- Lactococcus garvieae is a known fish pathogen with low virulence in humans.
- Infective endocarditis caused by L. garvieae is rare, with only 10 previous reports globally.
- This case represents the first reported instance of L. garvieae infective endocarditis in Japan.
Purpose of the Study:
- To report the 11th case of L. garvieae infective endocarditis.
- To document the first case in Japan.
- To discuss the clinical presentation and management of this rare infection.
Main Methods:
- Case report of a 55-year-old Japanese woman with native valve endocarditis.
- Identification of the pathogen using 16S ribosomal RNA gene sequencing.
- Clinical management including antimicrobial treatment.
Main Results:
- The patient presented with native valve endocarditis caused by L. garvieae.
- Complications included renal infarction, cerebral infarction, and mycotic aneurysms.
- Successful treatment with antimicrobial therapy led to patient recovery and discharge.
Conclusions:
- Lactococcus garvieae can cause severe infective endocarditis, even in healthy individuals.
- 16S ribosomal RNA gene sequencing is a valuable tool for pathogen identification.
- Despite its rarity, L. garvieae endocarditis is clinically treatable.

01:25Endocarditis II: Clinical Features of Infective Endocarditis
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...
01:25Endocarditis I: Introduction
Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...
01:18Endocarditis III: Medical Management
Infective endocarditis management involves a multifaceted approach encompassing infection prevention, lifestyle modifications, pharmacological therapy, and surgical management.Infection Prevention:Hand Hygiene: Thorough handwashing is crucial to prevent the spread of infection. Hand hygiene should be performed regularly, especially before and after using the restroom.Oral Hygiene: Good oral hygiene is essential. It includes brushing teeth immediately after waking up and before bed, flossing...
01:29Endocarditis IV: Nursing Management
Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...
01:18Bacterial Gastroenteritis
Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
01:22Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies
The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
