Coinfection with multiple Campylobacter strains occurs in sporadic human cases. This finding is crucial for investigating outbreaks involving distinct strains from patients and potential sources.
Area of Science:
- Microbiology
- Infectious Diseases
- Genetics
Background:
- Campylobacter infections are a common cause of bacterial gastroenteritis worldwide.
- Understanding strain diversity is essential for accurate diagnosis and public health surveillance.
Purpose of the Study:
- To investigate the frequency of coinfection with multiple Campylobacter strains in sporadic human infections.
- To characterize the identified strains using molecular and phenotypic methods.
Main Methods:
- Culturing and isolation of Campylobacter from fecal samples.
- Serotyping, phage typing, antibiotic resistance profiling.
- Molecular typing including pulsed-field gel electrophoresis and flagellin gene typing.
Main Results:
- Most patients were infected with a single Campylobacter strain.
- Coinfection with two distinct Campylobacter jejuni strains was identified in 7.5% of samples.
- One patient was infected with Campylobacter coli, while others had Campylobacter jejuni.
Conclusions:
- Coinfection with multiple Campylobacter strains is a documented occurrence in sporadic campylobacteriosis.
- These findings have significant implications for epidemiological investigations of Campylobacter outbreaks.
