Summary
This study reports the first case of chorioamnionitis caused by Leptotrichia trevisanii. The infection was identified in amniotic fluid and treated successfully, with the patient recovering fully.
Area of Science:
- Microbiology
- Obstetrics
- Infectious Diseases
Background:
- Chorioamnionitis is an infection of the amniotic fluid and membranes.
- Gram-negative bacilli are common causes of obstetric infections.
Observation:
- A 36-year-old multigravida woman presented with suspected chorioamnionitis.
- Gram staining of amniotic fluid revealed very long fusiform gram-negative bacilli.
- Bacterial culture showed pure, abundant growth of a catalase-positive, oxidase-negative bacterium, with greater growth under anaerobic conditions.
Findings:
- Matrix-assisted laser desorption ionization time of flight mass spectrometry identified the bacterium as Leptotrichia trevisanii.
- Microscopic examination of the placenta confirmed severe acute chorioamnionitis with abundant microorganisms.
- This is the first reported case of chorioamnionitis caused by Leptotrichia trevisanii.
Implications:
- This finding expands the spectrum of known pathogens causing chorioamnionitis.
- Early identification and appropriate antibiotic treatment (ampicillin and gentamicin) led to a favorable maternal outcome.
- Further research may be needed to understand the prevalence and clinical significance of Leptotrichia trevisanii in obstetric infections.

Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased...

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

The phylum Chlamydiae or Chlamydiota is composed of a single order, Chlamydiales. This phylum consists entirely of obligate intracellular parasites that infect eukaryotic hosts. While human pathogens within this group have been studied extensively, the phylum encompasses many species capable of interacting with various eukaryotic organisms. Members of Chlamydiae are typically small cocci, approximately 0.5 μm in diameter, and exhibit a distinctive developmental cycle. As is characteristic...

477
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

01:27Acute Pyelonephritis I: Introduction
778
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such...

Excavata is a diverse group of protists that includes both chemoorganotrophic and phototrophic species, with some thriving in anaerobic environments. Among the key groups within Excavata are diplomonads and parabasalids, which are flagellated protists that lack mitochondria and chloroplasts. These microorganisms typically inhabit anoxic environments, such as the intestines of animals, where they exist either symbiotically or as parasites, relying on fermentation for energy production. Some...
