Xanthomonas oryzae (Xo) merupakan patogen penyakit hawar daun bakteri (HDB) yang dapat mengurangi produktivitas padi secara nyata. Petani menanggulangi Xo dengan bakterisida sintetik dan penanaman varietas tahan di lapangan, namun belum sepenuhnya berhasil. Berdasarkan latar belakang tersebut perlu adanya solusi untuk mengendalikan mencari musuh alami yaitu virus menginfeksi bakteri.Tujuan pene...

BACKGROUND It has been shown that a high percentage of interleukin-8 (IL-8) in blood is cell associated. Recently, a simple method for determination of cell-associated IL-8 in whole blood after cell lysis has been described. The purpose of this study was to evaluate this method, to examine the influence of preanalytic sample handling, and to establish the concentration range of total IL-8 and i...

It is demonstrated that a diagnostic PCR for Borrelia burgdorferi can be inhibited in the presence of more than 500 ng of host (monkey skin) DNA. The inhibitor is the host DNA itself. An acceptable value for analytical sensitivity can be obtained by diluting the skin-B. burgdorferi proteinase K lysate to a level below the inhibitory concentration of the host DNA. Dilution of the lysate may obvi...

A total of 120 Limulus amoebocyte lysate (LAL) determinations were made on plasma obtained from normal, healthy human blood donors. Results demonstrated a mean endotoxin level in blood of 0.02 to 1.57 pg/ml. The amount of Escherichia coli endotoxin added to human plasma samples can be quantitated by both nephelometry and turbidimetry. Endotoxin-spiked samples were shown to be significantly diff...
