1. Biotechnological potential of Clostridium butyricum bacteria
In response to demand from industry for microorganisms with auspicious biotechnological potential, a worldwide interest has developed in bacteria and fungi isolation. Microorganisms of interesting metabolic properties include non-pathogenic bacteria of the genus Clostridium, particularly C. acetobutylicum, C. butyricum and C. pasteurianum. A well-known prope

2. Clostridium estertheticum em leite cru e em queijos parmesão e provolen / Clostridium estertheticum in raw milk and Parmesan cheese and provolen
A deterioração de queijos semicozidos e cozidos ou semiduros e duros, conhecida como tufamento tardio, tem sido o foco de vários estudos. Alguns microrganismos já foram relacionados com esta deterioração incluindo algumas espécies de Clostridium, como C. tyrobutiricum, C. butyricum, C. sporogenes e C. beijerinckii. Uma nova espécie, C. estertheticum,

3. Caracterização parcial de substância antagonista produzida por uma amostra de Clostridium butyricum
A produção de substâncias antagonistas por espécies bacterianas presentes em sistema de canais radiculares (SCR) infectados, tem um papel importante na colonização deste sítio. O objetivo deste estudo foi caracterizar parcialmente a substância antagonista produzida por amostra de Clostridium butyricum isolado de SCR infectados.A produção de substâ

4. Clostridium estertheticum in raw milk and Parmesan cheese and provolen / Clostridium estertheticum em leite cru e em queijos parmesão e provolen
The spoilage of semicooked and cooked cheeses and semihard and hard cheeses, known as late blowing, has been the focus of some studies. Some microorganisms already had been related with this spoilage including some species of Clostridium, as C. tyrobutiricum, C. butyricum, C. sporogenes and C. beijerinckii. A new species, C. estertheticum, is being incrimina

5. Poison as cure: a clinical review of botulinum toxin as an invaluable drug
Botulinum toxin is the most potent toxin known. It is readily absorbed from mucosal surfaces. If dispersed as an aerosol or mixed in the food or water it can lead to a large outbreak of botulism. The disease presents as a symmetric descending paralysis in an afebrile patient. Cranial nerve involvement with diplopia, dysarthria, dysphonia, dysphagia and respi

6. Survey of neuraminidase production by Clostridium butyricum, Clostridium beijerinckii, and Clostridium difficile strains from clinical and nonclinical sources.
Neuraminidase production was investigated in 57 Clostridium butyricum strains, 16 Clostridium beijerinckii strains, and 25 Clostridium difficile strains. Neuraminidase activity was found only in C. butyricum strains originating from one human newborn with neonatal necrotizing enterocolitis, two newborns with hemorrhagic colitis, one infected placenta, and on

7. Selective medium for isolation of Clostridium butyricum from human feces.
A selective medium, Clostridium butyricum isolation medium (BIM), is described for the isolation of C. butyricum from human feces. The BIM is a synthetic minimal medium and contains trimethoprim (16 micrograms/ml), D-cycloserine (10 micrograms/ml), and polymyxin B sulfate (20 micrograms/ml) as selective inhibitory agents. Qualitative tests indicated that C.

8. Genetic confirmation of identities of neurotoxigenic Clostridium baratii and Clostridium butyricum implicated as agents of infant botulism.
Two unusual neurotoxigenic clostridia isolated from fecal specimens from patients with type F and type E infant botulism were phenotypically identical to the existing species Clostridium baratii and C. butyricum, respectively. DNA hybridization experiments confirmed that one strain was C. baratii and that the other was C. butyricum. These species therefore d

9. Immunological characterization of Clostridium butyricum neurotoxin and its trypsin-induced fragment by use of monoclonal antibodies against Clostridium botulinum type E neurotoxin.
We examined the reactivities of Clostridium butyricum neurotoxin to nine monoclonal antibodies against Clostridium botulinum type E neurotoxin which recognize the light chain or the amino-terminal half (H-1 fragment) or the carboxyl-terminal half (H-2 fragment) of the heavy chain of botulinum neurotoxin. Butyricum neurotoxin and its derived chains did not re

10. Characterization of a neurotoxigenic Clostridium butyricum strain isolated from the food implicated in an outbreak of food-borne type E botulism.
Neurotoxigenic Clostridium butyricum was isolated from the food implicated in an outbreak of clinically diagnosed type E botulism in China. PCR assay showed that the isolate (LCL 155) contained the type E botulinum toxin gene. This appears to be the first report of neurotoxigenic C. butyricum causing food-borne botulism.

11. Comparative sequence analysis of the catB gene from Clostridium butyricum.
Sequence analysis of the Clostridium butyricum chloramphenicol acetyltransferase (CAT) gene, catB, showed that it encoded a CAT monomer of 219 amino acids with a molecular weight of 26,114. Comparison of the deduced amino acid sequence of the CATB monomer to those of sixteen other CATs showed that it was most closely related to the CATQ monomer from Clostrid

12. Ammonia assimilation pathways in nitrogen-fixing Clostridium kluyverii and Clostridium butyricum.
Pathways of ammonia assimilation into glutamic acid were investigated in ammonia-grown and N2-fixing Clostridium kluyverii and Clostridium butyricum by measuring the specific activities of glutamate dehydrogenase, glutamine synthetase, and glutamate synthase. C. kluyverii had NADPH-glutamate dehydrogenase with a Km of 12.0 mM for NH4+. The glutamate dehydrog
