Characterization of <i>Phytophthora</i> Species in Recycled Irrigation Water at a Container Nursery in Southwestern Virginia
… in recovery of <i>Phytophthora</i> spp. In pathogenicity tests, <i>P. cactorum, P. capsici, P. citrophthora,</i> and <i>P. nicotianae</i> caused significant mortality of <i>Salvia officinalis</i> and <i>P. cactorum</i> showed limited pathogenicity on <i>Gerbera jamesonii</i>. Asymptomatic …

The efficacy of two novel insecticides to control nuisance diptera breeding in sewage biological filters
… purificationprocesses. Laboratory based pathogenicity tests determined that the nematodeSteinernema feltiae is a viable biocide capable of infecting the larvae of sewage flies.Field trials at three sites using a dose of one million nematodes per m2 producedsignificant reductions (P<0.05) …

Phenotypic and biochemical characterisation of the causal agent of bacterial leaf streak of maize
… Pantoea, and Enterobacter. To elucidate the pathogenicity of the isolated strains, pathogenicity tests based on Koch's postulates were performed. Results from the pathogenicity tests confirmed that only the isolate Xanthomonas species was capable of inducing the characteristic BLS symptoms …

Fungi associated with the die-back of Pterocarpus angolensis (kiaat) in South Africa
… areas and were subsequently identified. Pathogenicity tests were used to evaluate the possible role that these species might play in the dieback of P. angolensis. Copyright

Identification of Pythium species inducing common bean (Phaseolus vulgaris L.) root rot symptoms and development of backcrosses to improve the level of varietal resistance to this disease
… different common bean producing areas in Rwanda. Pathogenicity tests of the 16 identified Pythium species were performed on a set of 10 common bean varieties. The results showed that all identified Pythium species were pathogenic to common bean: they all induce symptoms of root rot under …

Bio-control of root rot disease in vanilla
… where little information is available on fungal pathogenicity. Biocontrol is the main alternative for disease control in this crop, an attractive approach because of increasing concerns for environmental protection. The investigation considers two biocontrol strategies: first the introduction of …

Biological activity and regulation of cyclic lipopeptide production in Pseudomonas corrugata and Pseudomonas mediterranea
… in their MALDI-TOF MS spectra. Moreover, pathogenicity tests revealed that these long chain CLPs are important for P. corrugata virulence. Using real-time PCR we also ascertained that the regulators PcoR and RfiA are involved in corpeptins production/secretion. P. corrugata CFBP 5454 and …

Whole exome sequencing to investigate genetic variants of non-syndromic hearing impairment in a population of African ancestry
… variants were filtered based in rarity and pathogenicity. Tests for genetic differentiation and principle component analysis was performed on the combined patient exomes and combine control exomes. The first principle component analysis included data from African populations from the 1000 …
