Clostridium botulinum type F: isolation from venison jerky
Applied Microbiology
|August 1, 1972
Summary
A novel Clostridium botulinum type F strain was identified from venison jerky linked to a US outbreak. This nonproteolytic strain differs from the known Langeland type F, impacting botulism research.
Area of Science:
- Food microbiology
- Neuroscience
- Toxicology
Background:
- Botulism is a rare but serious paralytic illness caused by botulinum neurotoxins.
- Clostridium botulinum produces different types of neurotoxins, with type F being particularly uncommon.
Purpose of the Study:
- To characterize the Clostridium botulinum type F isolate from a venison jerky-associated outbreak in the United States.
- To compare the properties of this isolate with the prototype Langeland type F strain.
Main Methods:
- Bacterial isolation and identification from food samples.
- Biochemical and physiological characterization of the Clostridium botulinum isolate.
Main Results:
- Clostridium botulinum type F was successfully isolated from the implicated venison jerky.
- The isolated strain was found to be nonproteolytic, distinguishing it from the proteolytic prototype Langeland type F strain.
Conclusions:
- This study reports the only known type F botulism outbreak in the US, linked to venison jerky.
- The identification of a nonproteolytic type F strain provides new insights into the diversity and characteristics of Clostridium botulinum.
