Summary
Enterobacter cloacae enterotoxin boosts T-lymphocyte and natural killer cell activity. This thermolabile toxin influences both spontaneous and mitogen-activated blast lymphocytes, impacting cell proliferation.
Area of Science:
- Immunology
- Microbiology
- Cell Biology
Context:
- Investigating lymphocyte activation dynamics.
- Understanding the effects of bacterial toxins on immune cells.
Purpose:
- To determine the impact of Enterobacter cloacae thermolabile enterotoxin on lymphocyte blastogenesis.
- To compare the effects of the enterotoxin with known mitogens like phytohemagglutinin (PHA) and concanavalin A (ConA).
Summary:
- Enterobacter cloacae thermolabile enterotoxin increases the number of transforming T-lymphocytes.
- Phytohemagglutinin (PHA) primarily stimulates T-cell mitosis, while concanavalin A (ConA) stimulates natural killer cells.
- The enterotoxin stimulates mitotic activity in both T-cells and natural killer cells.
Impact:
- Reveals a novel immunomodulatory role for Enterobacter cloacae enterotoxin.
- Highlights the differential effects of mitogens and bacterial toxins on immune cell populations.
- Provides insights into bacterial pathogenesis and host immune responses.

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...
01:18Bacterial 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...
01:20Determinants of Bacterial Pathogenicity and Virulence
Pathogenic bacteria employ a variety of strategies to establish infections, including the secretion of extracellular enzymes that act as potent virulence factors. These enzymes facilitate bacterial colonization of host tissues and help evade immune surveillance. By targeting structural components of host tissues and interfering with immune mechanisms, these enzymes play a pivotal role in disease progression.Extracellular Enzymes Facilitating Tissue Invasion: Several bacterial pathogens secrete...
01:31Defense Against Bacterial Pathogens
The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

01:28Diphtheria
Diphtheria is an acute, toxin-mediated infectious disease that primarily affects the upper respiratory tract. It is caused by Corynebacterium diphtheriae, a Gram-positive, pleomorphic rod that lacks spore-forming capability and exhibits a characteristic club-shaped morphology under microscopic examination. While C. diphtheriae can asymptomatically colonize mucosal surfaces, clinical disease manifests only when the bacterial strain is lysogenized by a specific β-corynephage. This phage...
