Plasmids in Clostridium botulinum type A and Clostridium sporogenes
A procedure to rapidly screen Clostridium botulinum type A and Clostridium sporogenes for plasmids was developed. Plasmid profiles of five C. botulinum type A strains and seven C. sporogenes strains were determined and a possible relationship of plasmids to toxin production was examined. The …

Struktur-Funktions-Beziehung der ADP-Ribosyltransferase Clostridium botulinum C2-Toxin
Das Aktin ADP-ribosylierende Clostridium botulinum C2-Toxin ist ein binäres Toxin, das aus der Bindungskomponente C2II und der enzymatischen Komponente C2I besteht. C2I ADP-ribosyliert G-Aktin und depolymerisiert so das Aktinzytoskeletts. In der vorliegenden Arbeit wurde die …

Sodium hypophosphite inhibition of Clostridium botulinum in pasteurized comminuted pork
… for inhibition of growth and toxin production of Clostridium botulinum in a model meat system. Fresh comminuted pork was formulated to contain 0, 1000, or 3000 ppm sodium hypophosphite, with or without 50 ppm sodium nitrite, and 156 ppm sodium nitrite. The test formulations were inoculated with an …

Growth and survival of Clostridium botulinum type E in pasteurized oysters
The risk of toxin production by Clostridium botulinum type E in pasteurized oysters was evaluated. Thermal death time studies for type E spores in a oyster homogenate showed that the spores survived pasteurization at 550 C; D-values ranged from 65 to 100 min at 700 C and 880 to 1300 min at 550 C. …

Clostridium botulinum toxin development in refrigerated reduced oxygen packaged Atlantic croaker (Micropogonias undulatus)
… transmission rate (OTR) on toxin development by Clostridium botulinum in refrigerated raw vacuum packaged croaker fillets, and to determine if toxin development precedes microbiological and/or organoleptic spoilage. Raw croaker fillets were vacuum packaged in oxygen-permeable films (OTR of 10,000 …

The inhibition of Clostridium botulinum growth and toxin production by essential oils of spices
… outgrowth, growth, and toxin production of C. botulinum strains in microbiological media. The oils of clove, thyme, origanum, and cinnamon were studied for their mechanism of inhibition of C. botulinum 67B. The most effective oil, in combination with sodium nitrite at different levels was …

Untersuchungen zur Substratspezifität der ADP-Ribosyltransferasen Clostridium botulinum C2-Toxin und Clostridium perfringens Iota-Toxin
Clostridium perfringens Iota-Toxin und Clostridium botulinum C2-Toxin gehören zur Familie der binären Aktin-ADP-ribosylierenden Toxine. Die Toxine bestehen aus einer Enzymkomponente (ADP-Ribosyltransferase) und einer separaten Bindungs- und Translokationskomponente, die die Zellaufnahme vermittelt. …

Botulism and Its Ophthalmic Lesions as Determined by Research With the Toxin of Clostridium Botulinum
The subject of botulism has never received due consideration or study on the part of ophthalmologists, although recognition of the syndrome which involves the globe and its adnexa, is paramount in the clinical diagnosis of the disease. Strange to say most of the data relative to the ocular findings …

Real-time PCR for diagnosis of botulism and quantification of neurotoxin gene expression in Clostridium botulinum
… develop molecular methods for (i) detection of Clostridium botulinum in food and clinical samples, and (ii) monitoring the expression of the neurotoxin gene, cnt, during different growth phases and under different growth conditions. For the diagnosis of botulism, a real-time PCR-based method …

Impact of strain variability on the risk presented to chilled foods by non-proteolytic clostridium botulinum
… information on variability of non-proteolytic Clostridium botulinum at strain level. The research on strain variability covers practical experiments as well as literature surveys and focuses on heat resistance properties of non-proteolytic C. botulinum spores, variability in growth at chill …

Effect of modified atmosphere packaging on growth of Listeria monocytogenes and nonproteolytic Clostridium botulinum in cooked turkey
… of Listeria monocytogenes and nonproteolytic Clostridium botulinum type B spores in cooked, uncured turkey was investigated separately under varying conditions of modified atmosphere packaging (MAP), refrigerated and temperature-abuse storage, and lactic acid bacteria (LAB) competition. L. …

The inhibition of germination and growth of Clostridium botulinum 62A by BHA, BHT, TBHQ and 8-Hydroxyquinoline
… upon cell growth and spore germination of Clostridium botulinum type 62A was studied using a complex liquid medium. The inhibition of spore germination was further investigated using a defined liquid medium containing L-alanine, L-lactic acid and NaHC0₃. Cell growth was monitored by optical …
