Summary
Tetanus bacilli were detected in over a third of individuals in Peking using reliable culturing methods. These findings confirm the presence and shedding of tetanus bacilli within the digestive tract.
Area of Science:
- Microbiology
- Infectious Diseases
- Bacteriology
Background:
- Tetanus is a serious bacterial infection caused by Clostridium tetani.
- Accurate detection of tetanus bacilli is crucial for understanding its transmission and prevalence.
- Previous methods for identifying tetanus bacilli have limitations.
Purpose of the Study:
- To reliably detect the presence of tetanus bacilli in a human population.
- To investigate the prevalence of tetanus bacilli in stool samples.
- To understand the gastrointestinal colonization of tetanus bacilli.
Main Methods:
- Culturing suspected material for tetanus bacilli.
- Isolation of tetanus-like organisms.
- Demonstration of spasm-producing toxin neutralized by tetanus antitoxin.
Main Results:
- Tetanus bacilli were identified in 34.7% of stool samples from 78 individuals in Peking.
- The study confirmed the presence of tetanus bacilli in individuals on sterile diets.
- Significant shedding of tetanus bacilli spores was observed in stool samples.
Conclusions:
- Culturing is the definitive method for detecting tetanus bacilli.
- Tetanus bacilli are present in the digestive tracts of a notable portion of the population.
- Individuals can eliminate large quantities of tetanus bacilli spores.

01:29Tetanus
Tetanus is a life-threatening neurological disorder characterized by persistent muscle contractions and spastic paralysis. It is caused by Clostridium tetani, a motile, Gram-positive, rod-shaped, obligate anaerobe. These bacteria produce terminal endospores, giving them a distinctive “lollipop” or “tennis-racket” appearance. They thrive in anaerobic environments, such as those found in deep puncture wounds.Once introduced into the body, the spores germinate into vegetative cells. These cells...
01:30Bacterial Phylum Actinobacteria
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...
01:27Microbiota of the Large Intestine
The large intestine hosts the most densely populated microbial ecosystem in the human body. This complex community primarily consists of anaerobic bacteria, with Bacillota (formerly Firmicutes) and Bacteroidota (formerly Bacteroidetes) as the predominant groups. The distribution of these microbes varies along different sections of the large intestine, influenced by local environmental factors such as oxygen availability and nutrient composition.The cecum, located at the beginning of the large...
01:12Bacterial Toxins
Bacterial toxins are sophisticated virulence factors that enable pathogenic bacteria to interact with, invade, and damage host tissues. These toxins fall broadly into two types: protein exotoxins, which are secreted into the environment and target specific host receptors, and lipopolysaccharide endotoxins, which are structural components of the bacterial outer membrane released primarily during bacterial lysis or membrane shedding. Exotoxins generally act more selectively, binding to cell...
01:29Bacterial 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.

01:30Bacterial Phylum Spirochaetes
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 by a...
