Ventilator-associated pneumonia is preceded by lower-respiratory-tract colonization by pathogenic microorganisms that derive from endogenous or exogenous sources. Most ventilator-associated pneumonias are the result of exogenous nosocomial colonization, especially, pneumonias caused by resistant bacteria, such as methicillin-resistant Staphylococcus aureus and multi-resistant Acinetobacter baum...

a factorial experiment based on complete block design was conducted to study the interactive effects of sulfur fertilizer and thiobacillus bacteria on corn growth and root colonization with two species of mycorrhiza fungi. treatments were five levels of sulfur (s0: 0, s1: 50, s2: 100, s3: 150 and s4: 200 mg.kg-1 of dry soil), thiobacillus in two levels [no application (t0) and application of ba...

The coffee nursery is susceptible to endoparasitic Pratylenchus coffeae. Application of biological method in the suggested control nematode population and maintain seedling health. objectives this study were observe ability Arbuscular Mycorrhiza Fungi (AMF) Glomus spp. liquid inoculant Helper Bacteria (MHB) consortium Pseudomonas diminuta Bacillus subtilis for increasing AMF colonization reduci...

with the aim to examine lead tolerance of populus nigra (clone 62/154) in symbiosis with arbuscular mycorrhizal fungi, a greenhouse experiment was carried out in a factorial randomized complete scheme with two factors 1) fungal inoculation in 4 levels (control, inoculation with glomus mosseae, inoculation with g. intraradices and inoculation with g. mosseae + g. intraradices) and 2) lead in 4 l...

seed inoculation by means of mycorrhizal fungi can alleviate the side-effects of fungicides on production of crops and their yields. an experiment was conducted in 2009 at the research field of islamic azad university, faculty of agriculture, mahdasht, karaj. in order to investigate the influence of different kinds of fungicides on colonization of mycorrhizal species and on grain yield in soybe...

The ability of nematode-trapping fungi to colonize the rhizosphere of crop plants has been suggested to be an important factor in biological control of root-infecting nematodes. In this study, rhizosphere colonization was evaluated for 38 isolates of nematode-trapping fungi representing 11 species. In an initial screen, Arthrobotrys dactyloides, A. superba, and Monacrosporium ellipsosporum were...

An investigation has been made about the vesicular arbuscular mycorrhizal fungi colonization in some medicinal plants Catharanthus roseus, C. pusillus, Wrightia tinctoria, Thevetia peruviana, Nerium indicum and Alstonia scholaris belongs to family Apocyanaceae were screened for the occurrence and association of VA mycorrhizal fungi. All the plants screened in the study harbored VA mycorrhizal f...

Bacterial biofilm formation on fungi participates in the synergistic degradation of substrates, antagonism of fungal growth, bacterial utilization of fungi as nutrient sources, and the formation of more complex synergistic associations for the purposes of nutrient acquisition. While bacterial biofilm formation has been described in many systems, the molecular mechanisms that govern these intera...

Maize is one of the most important crops worldwide and is strongly dependent on arbuscular mycorrhiza (AM) fungi, organisms that form a mutualistic association with land plants. In maize, AM symbiosis enhances spike dry weight, spike length, spike circumference, and the dry weight and dimensions of the grain. Notwithstanding its ubiquitous nature, the detailed relationship between AM fungal col...
