Conjugative Botulinum Neurotoxin-Encoding Plasmids in Clostridium botulinum
BACKGROUND Clostridium botulinum produces seven distinct serotypes of botulinum neurotoxins (BoNTs). The genes encoding different subtype neurotoxins of serotypes A, B, F and several dual neurotoxin-producing strains have been shown to reside on plasmids, suggesting that intra- and interspecies transfer of BoNT-encoding plasmids may occur. The objective of the present study was to determine whe...
متن کاملClostridium botulinum Type D Lysogenized Organisms
We examined production of ADP-ribosyltransferase C3 in 11 strains of Clostridium botldinum type C and D and their nontoxigenic derivatives. Antisera to C3 proteins of type C organisms divided C3 proteins roughly into at least two groups, bearing no relation to their bacterial types. The C3 gene of type D strain South African was isolated from a toxigenic phage library, and the complete sequence...
متن کاملCharacterization of Clostridium botulinum spores and its toxin in honey
Botulism is a serious paralytic disease caused by Clostridium botulinum toxin in foods. There are seven recognized serotypes of botulinum neurotoxins among which the principal prevalent types in humans include A, B and E. Infant botulism results from intestinal colonization and toxin production by C. botulinum spores in babies less than 1 year old. Honey is the most important food discriminated...
متن کاملSerological studies of Clostridium botulinum type E and related organisms.
Clostridium botulinum type E antigens prepared from washed cells by either Formalin treatment or heating at 100 C were used for immunizing rabbits. Agglutination tests showed that high levels of antibody were produced by both types of preparations. Flagellar antigens were highly strain-specific, whereas the somatic antigens were sufficiently similar to produce complete cross-agglutination. One ...
