Invasive strain of Escherichia coli belonging to O group 29
Journal of Clinical Microbiology
|February 1, 1979
Abstract:
A strain of Escherichia coli isolated from a child with diarrhea was biochemically similar and antigenically identical (O and K antigens) to the standard strain of E. coli O group 29 and was positive in the Serény test for invasiveness, which suggests that it can cause a Shigella-like illness.
Insights
A newly identified Escherichia coli strain, identical to E. coli O group 29, caused diarrhea in a child. This pathogen demonstrated invasiveness, suggesting it can induce Shigella-like illness.
Area of Science:
- Microbiology
- Pathogen Identification
- Clinical Microbiology
Background:
- Escherichia coli (E. coli) is a common bacterium with diverse strains.
- Some E. coli strains are pathogenic and can cause various illnesses.
- Understanding specific pathogenic strains is crucial for public health.
Observation:
- A specific E. coli strain was isolated from a pediatric patient presenting with diarrhea.
- The isolated strain exhibited biochemical properties consistent with known E. coli.
- Antigenic analysis revealed the strain was identical to the standard E. coli O group 29.
Findings:
- The E. coli strain was antigenically identical to E. coli O group 29.
- The pathogen tested positive in the Serény invasiveness test.
- Invasiveness suggests the bacterium can penetrate host tissues, characteristic of severe infections.
Implications:
- This E. coli O group 29 strain possesses pathogenic potential.
- The findings suggest a potential cause for Shigella-like dysentery.
- Further research into this strain's virulence factors is warranted for effective treatment and prevention strategies.
