during the years 2007 and 2008, samples of winter jasmine (jasminum nudiflorum) with symptoms of galls on shoots were collected from shiraz, fars province, iran. gram and oxidase negative, aerobic bacterium that produced fluorescent pigment on kingۥs b medium was isolated from galls of infected trees. all isolates produced a hypersensitive reaction in tobacco. they were negative in arginine dih...
The current study aimed to detect the antimicrobial effect of cell free supernatant (CFS) Lactobacillus plantarum strain against Gram +ve and –ve bacterial strains. was isolated using selective media MRS agar. characterized on basis gram staining, colony morphology, biochemical tests DNA sequencing based method 16S ribotyping. A total four test strains (The three already reported (E.coli, S. au...
Posters are one of the media by presenting plots and pictures in explaining a material to make it easier for students understand. The purpose this study was poster based on research results local microorganisms (MOL) corn plant waste as animal feed bioactivators. This used MOL from cattle rumen molasses control (leaves, stems cobs) treatment. method experimentally visually observing morphologic...
in study, spherical silver nanoparticles (snps) were synthesized by chemical reduction method from a metal precursor silver nitrate in presence of an anionic surfactant and strong reducing agent. in this experimental work, snps are synthesized in presence of different concentration of stabilizing agent and effect of stabilizing agent on size distribution of snps have been observed. further anti...
RELIABILITY OF GLUCOSE OXIDASE STAINING AT THE ULTRASTRUCTURAL LEVEL FOR IMMUNOHISTOCHEMICAL STUDIES
BACKGROUND Although cerebrospinal fluid (CSF) culture is the diagnostic reference standard for bacterial meningitis, its sensitivity is limited, particularly when antibiotics were previously administered. CSF Gram staining and real-time PCR are theoretically less affected by antibiotics; however, it is difficult to evaluate these tests with an imperfect reference standard. METHODS AND FINDING...
Figure 25-4 Bacterial shapes and cell-surface structures Bacteria are classified into three different shapes: (A) spheres (cocci), (B) rods (bacilli), and (C) spiral cells (spirochetes). (D) They are also classified as Gram-positive or Gram-negative. Bacteria such as Streptococci and Staphylococci have a single membrane and a thick cell wall made of cross-linked peptidoglycan. They retain the v...
Trichomonas vaginalis, a flagellate protozoan parasite commonly found in the human genitourinary tract, is transmitted primarily by sexual intercourse. Diagnosis is usually by in vitro culture method and staining with Giemsa stain. There are laboratories that use Gram stain as well. We compared the use of modified Field's (MF), Giemsa, and Gram stains on 2 axenic and xenic isolates of T. vagina...
