| pasteuria nishizawae sp. nov., a mycelial and endospore-forming bacterium parasitic on cyst nematodes of genera heterodera and globodera. | this study describes pasteuria nishizawae sp. nov., a fourth species of the genus pasteuria. this mycelial and endospore-forming bacterium parasitizes the adult females of cyst-forming nematodes in the genera heterodera and globodera. the distinct ultrastructural features and unique host range found for this bacterium separate it from two closely related species, pasteuria penetrans, which parasitizes several species of root-knot nematodes of the genus meloidogyne, and pasteuria thornei, which a ... | 1991 | 1947427 |
| emended description of pasteuria nishizawae. | the description of the gram-positive, obligately parasitic, mycelial and endospore-forming bacterium, pasteuria nishizawae, is emended to include additional observations on the life cycle, host specificity and endospore morphology. the nucleotide sequence of the 16s rrna gene is also provided. | 2005 | 16014501 |
| pasteuria sp. parasitizing trophonema okamotoi in florida. | two populations of trophonema okamotoi parasitized by pasteuria sp. were found on liquidambar styraciflua (sweetgum) and on an unidentified tropical grass in north-central florida. endospores of this pasteuria sp. attached to motile vermiform second-stage juveniles (j2) and males of t. okamotoi, but not to other developmental stages. sporangia and new endospores were produced only inside the bodies of swollen and sedentary third- and fourth-stage juveniles and females that developed in the host ... | 1992 | 19283199 |
| Pasteuria endospores from Heterodera cajani (Nematoda: Heteroderidae) exhibit inverted attachment and altered germination in cross-infection studies with Globodera pallida (Nematoda: Heteroderidae). | The Pasteuria group of Gram-positive, endospore-forming bacteria are parasites of invertebrates and exhibit differences in host specificity. We describe a cross-infection study between an isolate of Pasteuria from pigeon pea cyst nematode, Heterodera cajani, which also infects the potato cyst nematode, Globodera pallida, from the United Kingdom. A proportion of the attached endospores, 13% on H. cajani and 22% on G. pallida adhere to the cuticle in an inverted orientation. Inverted and conventio ... | 2011 | 22092805 |
