| isolation and characterization of clostridium perfringens from apparently healthy animals of the shandong province of china. | in a pilot study the presence and frequency of clostridium (c.) perfringens was investigated among apparently healthy farm animals in the shandong province of china. 748 faecal samples were collected from 9 pig-, 4 sheep-, 7 cattle- and 5 rabbit farms. c. perfringens was isolated from 124 samples (16.6%). the isolates were classified into major toxin types by using pcr analysis detecting the genes encoding these toxins. all isolates were identified as c perfringens toxin type a. there are also s ... | 2007 | 17970339 |
| clostridium perfringens toxin types from freshwater fishes in one water reservoir of shandong province of china, determined by pcr. | four hundred and twenty intestinal content samples (not including intestinal tissues) of freshwater fishes (60 silver carps, 100 carps, 100 crucian carps, 60 catfishes and 100 zaieuws) caught from one water reservoir were examined bacteriologically for the occurrence of c. perfringens. isolates were examined by polymerase chain reaction (pcr) for genes encoding the four lethal toxins (alpha, beta, epsilon and iota) for classification into toxin types and for genes encoding enterotoxin and the no ... | 2008 | 18717056 |
