root rot disease of broad-bean caused by fusarium solani is a serious disease of this crop. due to high cost and difficulty of the disease control, interaction between root nodulating bacteria and fusarium. solani were evaluated to use for disease management. broad-bean root nodulating bacteria were isolated and their interaction with f. solani was investigated in culture medium in a completely...

Understanding how bacteria move close to a surface under various stimuli is crucial for a broad range of microbial processes including biofilm formation, bacterial transport and migration. While prior studies focus on interactions between single stimulus and bacterial suspension, we emphasize on compounding effects of flow shear and solid surfaces on bacterial motility, especially reorientation...

A simple method for capsular serotype determination of Klebsiella is described, using staphylococci or latex particles coated by specific antibodies and the supernatant of a bacterial suspension in saline as antigen. These methods may be at least as reliable as other methods and easier to perform and less expensive than other methods.

A new commercial system for rapid extraction of DNA, consisting of a card on which a drop of bacterial suspension is spotted, was evaluated with 43 mycobacterial strains. Once dried, a small disk of the seeded area was directly transferred in the amplification mixture. All the samples produced good quality amplification products which were satisfactorily sequenced.

Abstract The use of bacteriophages to control the development different bacterioses, including those caused by bacterium Xanthomonas campestris is one most promising areas in field plant protection. At same time, selection active and determination parameters their remains urgent tasks this direction. phage preparations with low initial concentration particles may not only prevent bacterial dise...

PURPOSE To quantify and compare the in vitro adherence of Staphylococcus epidermidis and Pseudomonas alcaligenes to different intraocular lenses (IOLs). METHODS Fourteen intraocular lenses were used in the experiment. Four of polymethylmethacrylate (PMMA), four of silicone, four of hydrogel and two of acrylic. Eight intraocular lenses were placed in eight test tubes containing 4 ml of Pseudom...

Hunt et al. (2) and Norton (4) showed that the northern root-knot nematode, Meloidogyne hap/a Chitwood, increased the incidence of bacterial wilt in alfalfa. Hunt et al. (2) also f o u n d t h e b a c t e r i a l wilt organism, Corynebacterium insidiosum (McCuU) H. L. Jens., in plant tissue that had been inoculated only with the bacteria. This would indicate that the role of M. hapla is somethi...

OBJECTIVES To measure antibacterial action of photoactivated disinfection (PAD) on endodontic bacteria in planktonic suspension and root canals. METHODS Four bacteria, Fusobacterium nucleatum,Peptostreptococcus micros, Prevotella intermedia and Streptococcus intermedius, were tested in suspension. After mixing equal volumes of Tolonium chloride and bacterial suspension for 60s, each 200 micro...
