Different soil bacteria, actinobacteria and fungi contribute to pathogen and disease suppression through various mechanisms related to competition, antibiosis
, nutrition and induced disease resistance.
maculatus, expressing resistance through antibiosis
and/or non-preference for feeding.
The appearance of mycelium growth and ascospore germination inhibition on agar plates is considered as antibiosis
and competition for nutrients and / or space for growth (Cook and Baker, 1983).
The plants for studies of antibiosis
were sown in plastic trays, and 1 plant was transplanted at the first true leaf stage in plastic pots (25 cm ht x 20 cm diam) containing substrate made of 50% dark top soil from the region + 25% sand + 25% fowl manure.
Results obtained for nutritional indexes indicated that antibiosis
resistance characteristics were present in genotypes from cluster I, namely, Aelton, Arzm 05 083, Composto Chico, Composto Gaucha, Marcia, Mateus, and Viviane (Table 1).
Plant resistance mechanisms are classified as antixenosis, antibiosis
On the same day, an incision of the retropharyngeal abscess was performed, and an intravenous (i.v.) antibiosis
with ampicilline and sulbactam was initiated.
This may be due to undeniably its mode of action like competition, antibiosis
and mycoparasitim and it possess some important secondary metabolites and antibiotics like harzianiol and so many.
, production of antibiotic compounds and inhibition of other microbes, is the most important mechanism expressed by the antagonistic bacteria .
Initial parenteral antibiosis
was accomplished with Ceftriaxone (Intacef (d)) @15mg/kg b.wt.
The mechanisms include competition for space and nutrients, antibiosis
, antagonism, inhibition of pathogen enzymes and plant growth stimulation (Harman et al., 2004; Abdel-Khair et al., 2010).
Because of certain properties of metal flavonoid complexes such as synergic effect of metal ions and flavonoids, access to target spots as well as strong binding forces produced from the change in complex structure may contribute to many biological activities for instance, anti-tumor, antivirus, antibiosis
, anti-free radical and anti-inflammatory .
