After Clostridium botulinum type G organisms and toxin were identified in necropsy specimens in cases of unexplained death in adults and infants (O. Sonnabend, W. Sonnabend, R. Heinzle, T. Sigrist, R Dirnhofer, and U. Krech, J. Infect. Dis. 143:22-27, 1981), extensive research to detect C. botulinum type G in soil samples from Switzerland was done. A total of 41 specimens from virgin soil and f...

Clostridium botulinum is a dangerous pathogen that forms the highly potent botulinum toxin, which when ingested causes a deadly neuroparalytic disease. The closely related Clostridium sporogenes is occasionally pathogenic, frequently associated with food spoilage and regarded as the non-toxigenic equivalent of Group I C. botulinum. Both species form highly resistant spores that are ubiquitous i...

In France, human botulism is mainly food-borne intoxication, whereas infant botulism is rare. A total of 99 group I and II Clostridium botulinum strains including 59 type A (12 historical isolates [1947-1961], 43 from France [1986-2013], 3 from other countries, and 1 collection strain), 31 type B (3 historical, 23 recent isolates, 4 from other countries, and 1 collection strain), and 9 type E (...

INTRODUCTION Clostridium botulinum is known to cause descending paralysis in infants throughout the world. METHODOLOGY The subject of this study was a three-month-old Costa Rican boy who was hospitalized because of poor suction and feeding, hypotonia, and constipation. Clinical history and physical examination findings suggested infant botulism. Samples were sent to the Winnipeg Public Health...

background: food-born botulism is caused by ingestion of contaminated food with clostridium botulinum neurotoxin. case: in food-born botulism, due to acetylcholine release blockade, neuromuscular signs and symptoms are common, but in this case report we present a food-born botulism with papiledema and venous sinus thrombosis. conclusion: papiledema and fever could not rule out the diagnosis of ...

Cold-tolerant, neurotoxigenic, endospore forming Clostridium (C.) botulinum type E belongs to the non-proteolytic physiological C. botulinum group II, is primarily associated with aquatic environments, and presents a safety risk for seafood. High pressure thermal (HPT) processing exploiting the synergistic effect of pressure and temperature can be used to inactivate bacterial endospores. We inv...

Clostridium sporogenes PA 3679 is a non-toxic endospore former that is widely used as a surrogate for Clostridium botulinum by the food processing industry to validate thermal processing strategies. PA 3679 produces spores of exceptionally high heat resistance without botulinum neurotoxins, permitting the use of PA 3679 in inoculated pack studies while ensuring the safety of food processing fac...
