| identification of symbiotic bacteria (photorhabdus and xenorhabdus) from the entomopathogenic nematodes heterorhabditis marelatus and steinernema oregonense based on 16s rdna sequence. | two species of entomopathogenic nematodes, heterorhabditis marelatus and steinernema oregonense, were described recently from the west coast of north america. it is not known whether the bacterial symbionts of these nematodes are also unique. here we compared partial 16s rrna sequences from the symbiotic bacteria of these two nematodes with sequence from previously described photorhabdus and xenorhabdus species. the 16s sequence from the new xenorhabdus isolate appears very similar to, although ... | 2001 | 11273687 |
| steinernema akhursti sp. n. (nematoda: steinernematidae) from yunnan, china. | a new species of entomopathogenic nematode, herein described as steinernema akhursti sp. n., was recovered from soil samples collected from yunnan province, the people's republic of china. both morphological and molecular data show congruently that s. akhursti sp. n. belongs to the steinernema feltiae group. it can be separated from all described steinernema species by the combined morphological and morphometrical characters of various stages of the nematodes. for the first generation male, the ... | 2005 | 16289544 |
