“…Since disinfected greenhouse soil can be recolonized with FORL, crown and root rot disease control is difficult. On the other hand, while FOL only affects solanaceous plants, FORL is able to infect a total of 37 plant species and varieties belonging to Solanaceae, Leguminosae, Cucurbitaceae, and Chenopodiaceae (Rowe 1980;Menzies et al 1990). Therefore, some weeds, as well as the tomato crops, should be considered in crown and root rot control.…”

Levofloxacin was labeled with 99m Tc using cysteine • HCl as co-ligand and SnCl 2 .2H 2 O as reducing agent. The influence of various parameters such as amount of cysteine • HCl, reducing agent, pH value, and reaction time on labeling process was studied. After optimizing the conditions the labeling was performed at pH 5 using 1 mg of levofloxacin, 500 μ g of cysteine• HCl, 50 μ g of SnCl 2 .2H 2 O, and 15 min reaction time. The radiochemical purity was determined with the help of instant thin layer chromatography (ITLC) and reverse phase high performance liquid chromatography (RP-HPLC) which was more than 95% and was stable for up to 6 h. Biodistribution of 99m Tc-levofloxacin ( 99m Tc-lefx) was studied in infection induced rat models using live Staphylococcus aureus and heat killed S. aureus (sterile inflammation model). In the case of the live S. aureus induced abscess model, the accumulation of 99m Tc-lefx at target was 3.96, which was higher than that of 99m Tc-ciprofloxacin ( 99m Tc-cifx), taken as the control.

Characterization of fungi transferred by dust storms in Kuwait and their plant pathogenicity

2015

Dust storms carry large amounts of plant detritus and microorganisms that may cause diseases in humans, animals or plants. These storms are frequent in Kuwait throughout the year. This research was conducted to identify the fungal species carried by the dust storms in Kuwait, originating from the northwesterly direction, with emphasis on plant pathogens. Fungi were isolated from settled dust samples and identified using established microbiological and molecular approaches. Fungal isolates identified as Fusarium oxysporum from settled dust were examined for pathogenicity using a number of crop plants. In total, 17 genera of fungi were identified in the dust samples. These fungi included plant pathogens or facultative plant parasites that were transported in the dust storms as viable propagules. The most common dust-carried fungi belonged to the genera Fusarium, Alternaria, Ulocladium, Phoma, Aspergillus, Acremonium and Penicillium. The F. oxysporum isolates that had been characterized by partial 18S rRNA gene sequencing were pathogenic, causing root and stem rot in tomato, bean and cucumber, but not squash.

“…An alternative model of pathogenicity and host range would be that of F. oxysporum f. sp. Radicislycopersici (Rowe, 1980), a forma specialis consisting of root-and crown-rot pathogens that are highly host specific (Jarvis et al, 1975) or typically have a wider host range while exhibiting greater virulence to the host of origin (Rowe, 1980). Based on the symptomatology for these European strains, as mostly root-and crown-rot pathogens (Caesar et al, 1998), and the host ranges described herein, they may more closely resemble the former pattern for strains of F. oxysporum f. sp.…”

Abstract:Host-range tests were conducted in a greenhouse using 9 European and 11 U.S. strains of Fusarium spp. pathogenic to Euphorbia spp. Plants of 12 grass species native to the rangelands of North America were raised from seed, planted in soil infested with each strain, and assessed for dry weight after 24 weeks. Five of 11 U.S. strains of Fusarium spp. significantly reduced the dry weight of at least 1 species of grass native to North America. Only 3 native grass species were affected: Idaho fescue (Festuca idahoensis), big bluestem (Andropogon gerardi), and big bluegrass (Poa ampla). Mean reductions ranged from 56 to 92%. A single European strain caused a 53% reduction in dry weight of 1 grass species, sand lovegrass (Eragrostis tichodes). Root-dip assays of 3-week-old seedlings in the greenhouse, with assessment over 3 weeks followed by 9 weeks of further observation and recording of dry weights of surviving plants were used to assess pathogenicity to 27 cultivated plant species. Two of the 3 most virulent U.S. strains failed to cause disease on any crop species according to these criteria. Three U.S. strains were positive in root-dip assays, each to a single crop species, causing vascular discoloration of flax (Linum ussitatissimum) and root necrosis of okra (Hibiscus esculentus) and cotton (Gossypium hirsutum). Neither of the 2 most virulent European strains exhibited pathogenicity to any of 12 crop species. Two other European strains exhibited host ranges comprised of 3 and 4 crop species. Two strains of F. proliferatum from the U.S. and Europe differing in host range were vegetatively compatible. The greater frequency of disease incidence on Euphorbia in Europe and the narrow host range and apparently greater 1
