[en] Cranial eumycetoma (CE) due to direct inoculation of Madurella grisea into the scalp is extremely rare. We describe a case of CE caused by direct inoculation of M. grisea with the characteristic MRI findings of the “dot-in-circle” sign and a conglomeration of multiple, extremely hypointense “dots.”

[en] A newly isolated microbial inoculant showing potential as biofertilizer, M99 was evaluated for its effect on brassica plant in a greenhouse experiment. This experiment was carried out to evaluate the effect of M99 liquid biofertilizer (B), radiation processed chitosan (RPC) and chemical fertilizer (CF) on the growth and yield of brassica plant. The seedlings of brassica plant were grown in pots containing approximately 1.87 kg of soil mixture, dispersed in complete randomized design (CRD) with 20 replications for each treatment. This experiment consisted of 4 treatments: control (without CF, B, RPC); T1 (100% CF), T2 (B), T3 (RPC) and T4 (B, RPC). After completion of the experiment (33 DAT), the plants were harvested and separated according to parts viz., aboveground parts (stem, leaf) and roots to determine the growth characteristics and yield of the plant. Results showed that there was no significant difference among all the treatments in terms of leaf number. The tallest plant was observed in 100% CF treated brassica plant while the B and RPC treated plant did not show significant difference in plant height. Plant with longest root was observed in plant subjected to combination of B and RPC. In term of yield, the fresh weight and dry weight of aboveground plant (stem + leaves) of brassica plant treated with combination of B and RPC were comparable to 100 % CF treated plant. Synergistic effects between B and RPC on brassica plant were observed specifically in terms of root growth characteristics (length, fresh weight and dry weight) and yield (fresh weight and dry weight of aboveground parts). Combination of reduced amount of CF with B and O will be studied in the future. (author)

[en] Experiments were conducted with radiation sterilization of the carrier substrate for RIZOBIN, an inoculation material for the seeds of leguminous plants. The sterile substrate was used for propagating Rhizobia, whose concentration was measured. Complete sterility was achieved by irradiation with a dose of 35 kGy. If the container was kept hermetically sealed, the complete sterility was preserved for 18 months. Using the substrate thus prepared increased the number of Rhizobia by two orders of magnitude over that obtained with a heat-sterilized substrate. (author). 3 tabs

[en] A rhizobox experiment was conducted to investigate degradation of decabromodiphenyl ether (BDE-209) in the rhizosphere of ryegrass and the influence of root colonization with an arbuscular mycorrhizal (AM) fungus. BDE-209 dissipation in soil varied with its proximity to the roots and was enhanced by AM inoculation. A negative correlation (P < 0.001, R² = 0.66) was found between the residual BDE-209 concentration in soil and soil microbial biomass estimated as the total phospholipid fatty acids, suggesting a contribution of microbial degradation to BDE-209 dissipation. Twelve and twenty-four lower brominated PBDEs were detected in soil and plant samples, respectively, with a higher proportion of di- through hepta-BDE congeners in the plant tissues than in the soils, indicating the occurrence of BDE-209 debromination in the soil-plant system. AM inoculation increased the levels of lower brominated PBDEs in ryegrass. These results provide important information about the behavior of BDE-209 in the soil-plant system. - Research highlights: → BDE-209 dissipation in soil was affected by the proximity to the roots. → Microbial degradation contributes greatly to BDE-209 dissipation in the soil. → Twelve and twenty-four lower brominated PBDEs were detected in soil and plant samples. → AM inoculation increased root uptake and accumulation of BDE-209. - BDE-209 dissipation and degradation in soil were affected by both its proximity to ryegrass roots and inoculation with an AM fungus.

[en] Inoculation expedition of agar wood is a main field works for researcher in Nuclear Malaysia to prove the real inoculation of agar wood in real jungle. These expeditions was conducted fourth times in the jungles of Malaysia including Gunung Tebu in Terengganu, Murum in Belaga, Sarawak, Kampung Timbang in Kota Belud, Sabah and Nuclear Malaysia itself. This expedition starts from preparation of samples and equipment, transportation into the jungle, searching and recognition of agar wood and lastly, inoculation of the agar wood. Safety aspects precedence set out in the preparation and implementation of this expedition. (author)

[en] Live-attenuated viruses derived from SIV and SHIV have provided the most consistent protection against challenge with pathogenic viruses, but concerns regarding their long-term safety and efficacy have hampered their clinical usefulness. We report a longitudinal study in which we evaluated the long-term safety and efficacy of ΔvpuSHIV_PPC, a live virus vaccine derived from SHIV_PPC. Macaques were administered two inoculations of ΔvpuSHIV_PPC, three years apart, and followed for eight years. None of the five vaccinated macaques developed an AIDS-like disease from the vaccine. At eight years, macaques were challenged with pathogenic SIV and SHIV. None of the four macaques with detectable cellular-mediated immunity prior to challenge had detectable viral RNA in the plasma. This study demonstrates that multiple inoculations of a live vaccine virus can be used safely and can significantly extend the efficacy of the vaccine, as compared to a single inoculation, which is efficacious for approximately three years

[en] A natural phenanthrene-degrading consortium CON was inoculated with an exogenous strain Sphingobium sp. (ex Sp. paucimobilis) 20006FA yielding the consortium called I-CON, in order to study ecological interactions into the bacterial community. DGGE and proteomic profiles and analyses by HTS (High-Throughput Sequencing) technologies demonstrated inoculant establishment and changes on CON composition. Inoculation increased degradation efficiency in I-CON and prevented intermediate HNA accumulation. This could be explained not only by the inoculation, but also by enrichment in Achromobacter genus at expense of a decrease in Klebsiella genus. After inoculation, cooperation between Sphingobium and Achromobacter genera were improved, thereby, some competition could have been generated, and as a consequence, species in minor proportion (cheaters), as Inquilinus sp. and Luteibacter sp., were not detected. Sequences of Sphingobium (corresponding to the inoculated strain) did not vary. PICRUSt predicted a network with bacterial phylotypes connected with enzymes, showing functional redundancy in the phenanthrene pathway, with exception of the first enzymes biphenyl-2,3-diol 1,2-dioxygenase and protocatechuate 4,5-dioxygenase that were only encoded in Sphingobium sp. This is the first report where a natural consortium that has been characterized by HTS technologies is inoculated with an exogenous strain in order to study competitiveness and interactions.
