Correlations between virulence and other characters of Clostridium perfringens type A.
The correlation analysis which has already proved its value in ecology has not yet been applied to the determination of virulence indicators. Its application to a group of Clostridium perfringens type A strains has brought out some characters that may be considered as virulence indicators. This study suggests that the toxicity of the culture supernatant fluids for mice is significantly correlat...

Comparison of virulence plasmids among Clostridium perfringens type E isolates.
Clostridium perfringens type E isolates produce iota-toxin, which is encoded by iap and ibp genes. Using Southern blot analyses, the current study identified iap/ibp plasmids of approximately 97 or approximately 135 kb among eight type E isolates. For most of these isolates, their iap/ibp plasmid also encoded urease and lambda-toxin. However, the beta2-toxin gene, if present, was on a different...
متن کاملClostridium perfringens Type E Virulence Traits Involved in Gut Colonization
Clostridium perfringens type E disease in ruminants has been characterized by hemorrhagic enteritis or sudden death. Although type E isolates are defined by the production of alpha and iota toxin, little is known about the pathogenesis of C. perfringens type E infections. Thus far, the role of iota toxin as a virulence factor is unknown. In this report, iota toxin showed positive effects on adh...
متن کاملon translation of phatic communion and socio-cultural relationships between the characters of the novels
phatic communion is a cultural concept which differs across cultures. according to hofstede (2001), the u.s. tends to have individualistic culture; however, asian countries tend to have collectivistic cultures. these cultures view phatic communion differently. in individualistic cultures like u.s., phatic communion reflects speakers’ socio-cultural relationships in conversations. to see whether...
