Pathogenicity of Aseptic Bursaphelenchus xylophilus
Pine wilt is a disease of pine (Pinus spp.) caused by the pine wood nematode (PWN), Bursaphelenchus xylophilus. However, the pathogenic mechanism of pine wilt disease (PWD) remains unclear. Although the PWN was thought to be the only pathogenic agent associated with this disease, a potential role for bacterial symbionts in the disease process was recently proposed. Studies have indicated that a...
متن کاملPathotypes of the Pinewood Nematode Bursaphelenchus xylophilus.
An isolate of Bursaphelenchus xylophilus from Pinus sylvestris in Missouri infected and reproduced in 2-3-year-old seedlings of P. sylvestris and to some extent in seedlings of P. nigra. Wilting, however, occurred only in P. sylvestris. B. xylophilus isolated from P. strobus in Vermont infected and reproduced only in P. strobus seedlings. P. taeda seedlings were resistant to both of these isola...
متن کاملGenomic Differences among Pathotypes of Bursaphelenchus xylophilus.
Total genomic DNA from Bursaphelenchus xylophilus pathotypes MPSy-1 and VPSt-1 and from B. mucronatus was digested with restriction endonucleases. DNA fragments were electrophoretically separated, Southern blotted to nitrocellulose, and hybridized to genomic DNA from one of the isolates. The resulting hybridization patterns indicate genomic differences in repetitive DNA sequences among these po...
متن کاملComparative Studies between Portuguese and Japanese Isolates of the Pinewood Nematode, Bursaphelenchus xylophilus.
Comparative studies between Portuguese (T and HF) and Japanese (S10, T4, C14-5 and OKD-1) isolates of the pinewood nematode Bursaphelenchus xylophilus have been made in order to provide information to better understand the possible origin of the Portuguese isolates, recently introduced in the European Union. The main comparative aspects investigated were pathogenicity (seedling mortality ratio)...
متن کاملGenetic variation of Sporothrix globosa isolates from diverse geographic and clinical origins in China
Sporothrix globosa is the main causative agent of sporotrichosis, a common mycosis that usually affects the skin, in China. Despite increasing efforts in the molecular identification of this fungal pathogen, its modes of transmission and epidemiology remain poorly understood. The goals of this study were to assess the genetic diversity of S. globosa using amplified fragment length polymorphism ...
