The ability of different H pylori strains isolated from biopsy samples to stimulate TNF-alpha from PBMCs was significantly lower than that of E coli. Sonicated bacteria, as compared to intact bacteria, was a very poor inducer of TNF-alpha mRNA expression, suggesting that the conformation of lipopolysaccharides (LPS) on the outer leaflet of the outer membrane is not totally conserved in sonicated bacteria.
Mewabahnya penyakit yang tergolong baru di Kabupaten Lombok Timur saat ini telah mengakibatkan kematian dengan waktu yang relatif singkat pada ikan mas yang dibudidayakan. Penelitian ini dilakukan untuk mengetahui dan mendeskripsikan jenis - jenis patogen penyebab penyakit ikan mas di Kabupaten Lombok Timur. Proses identifikasi dimulai dengan mengkultur bakteri dari organ ikan mas yang terinfeksi yaituginjal dan cairan abdomen. Bakteri yang didapat diidentifikasi secara morfologi dan biokimia kemudian di cocokkan dengan buku panduan Bergey's Manual of Determinative Bacteriology. Hasil pencocokan tersebut menujukkan bahwa jenis bakteri yang terdapat pada organ ginjal dan cairan abdomen ikan mas yang terserang penyakit di BBI Aikmel adalah Edwarsiella tarda dan yersinia sp.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
