Bacterial Phylum Bacteroidota

Bacterial Phylum Bacteroidota

The phylum Bacteroidota includes over 700 species classified into four primary orders: Bacteroidales, Cytophagales, Flavobacteriales, and Sphingobacteriales. These gram-negative, non-sporulating rods exhibit saccharolytic capabilities and can be aerobic or fermentative, encompassing obligate aerobes, facultative aerobes, and obligate anaerobes. Many species display gliding motility, though some are nonmotile or use flagella. The genus Bacteroides is well-studied due to its significant role in...

Bacterial Toxins

Bacterial 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...

Bacterial Phylum Proteobacteria

Bacterial Phylum Proteobacteria

Proteobacteria, one of the largest and most diverse bacterial phyla, encompasses a wide range of Gram-negative bacteria distinguished by their outer membrane composed of lipopolysaccharides. These microorganisms exhibit various metabolic capabilities, including phototrophy, chemolithotrophy, and heterotrophy, and thrive in diverse environments from soil to aquatic systems and host-associated niches. The phylum is divided into six classes: Alphaproteobacteria, Betaproteobacteria,...

Bacterial Phylum Actinobacteria

Bacterial 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...

Bacterial Phylum Firmicutes

Bacterial Phylum Firmicutes

Firmicutes is a diverse phylum of Gram-positive bacteria characterized by a low GC content in their genomes. This phylum includes organisms with monoderm or diderm cell envelopes, highlighting a complex evolutionary history. Firmicutes comprises several major orders, including Lactobacillales, Clostridiales, and Bacillales, which exhibit remarkable diversity in their morphology, metabolism, and ecological roles.The order Lactobacillales includes lactic acid bacteria, which are fermentative...

Bacterial Gastroenteritis

Bacterial 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...

Culturing and Maintaining Clostridium difficile in an Anaerobic Environment

Culturing and Maintaining Clostridium difficile in an Anaerobic Environment

Published on: September 14, 2013

Summary

This summary is machine-generated.

Clostridium difficile, a dangerous pathogen, can grow using CO2 and H2 as its only energy source, unlike previously assumed. This autotrophic ability may explain its survival and pathogenicity in the human gut.

Area of Science:

Microbiology
Bacterial Pathogenesis
Metabolic Flexibility

Background:

Clostridium difficile infection (CDI) incidence and virulence have increased globally.
CDI is a primary cause of antibiotic-associated and nosocomial diarrhea, particularly severe in the elderly.
Bacterial pathogens are typically considered heterotrophic, utilizing organic nutrients.

Purpose of the Study:

To investigate the metabolic capabilities of Clostridium difficile beyond heterotrophy.
To determine if C. difficile can utilize inorganic carbon and energy sources for growth.
To explore the implications of autotrophy for C. difficile pathogenicity.

Main Methods:

Culturing of clinical and rumen isolates of C. difficile under autotrophic conditions (CO2+H2).
Genetic analysis to identify conserved genes associated with autotrophic growth.
Comparative culturing experiments to assess the stability of autotrophic growth after prolonged heterotrophic cultivation.

Main Results:

C. difficile demonstrated the ability to grow using CO2 and H2 as the sole carbon and energy source.
Genes enabling autotrophic growth were highly conserved across different strains.
The capacity for autotrophic growth diminished or was lost with prolonged heterotrophic culturing.

Conclusions:

C. difficile is the first identified bacterial pathogen with autotrophic capabilities.
Metabolic flexibility, including autotrophy, may enhance C. difficile survival and niche differentiation in the gut.
This adaptability likely contributes to the organism's pathogenicity and persistence.
