Published: May 2020

Fungi associated with diseased seeds of Sesamum indicum L. from four markets in Jos and Okene central market were isolated to study the deteriorative changes in lipid content. In terms of number and fungal species abundance, Faringada market had the highest fungal occurrence, while Aspergillus chevaliari showed the highest percentage occurrence in that market. Visually healthy seeds of Sesanum indicum were inoculated with spores of each of the nine fungi isolated from diseased seeds and incubated at 25±20C for 7days. The healthy and fungal infected seeds were analysed for their lipid content. Significant decreases in lipid content were observed in the seeds inoculated with all the fungi except in seeds inoculated with G. candidum, which showed increase in lipid content. A. chevalieri was responsible for the maximum depletion of the lipid content of the seeds. The results clearly indicate that these fungal species are capable of depleting the lipid content in storage.

As water resources become more and more scarce, production of crops under dry land conditions brings agriculture into potential conflict with other uses of water. There is an emerging awareness that the orientation of the goals of plant breeding can be shifted to create crops that can offset the negative impacts of agriculture on the environment in order to make agriculture more sustainable. Here we have explored the possibility to select lines of wheat, the crop that occupies more land than any individual crop, that contribute to the bioprecipitation cycle. In this cycle the ice nucleation (IN) active component of the microflora on leaves contributes to the ice nuclei in the atmosphere that activate processes in clouds necessary for rainfall. In line with this long term goal, we have deter-mined the capacity of breeding lines of wheat, adapted to dry land conditions, to harbor IN active bacteria. In particular, we focused on Pseudomonas syringae, the most ubiquitous of the IN active bacteria on plants. Because strains of this bacterium can be a plant pathogen, we evaluated the abundance of non-pathogenic IN active strains of P. syringae on a range of wheat genotypes from the research program of the International Center for Agricultural Research in the Dry Areas. Of the 25 genotypes of bread wheat examined, leaves of 12 genotypes naturally harbored P. syringae in the field. Eight of these genotypes harbored populations of IN active P. syringae with an impaired Type 3 Secretion System (involved in pathogenicity) as high as 4 x 105 105 CFU g-1 of leaf tissue. Three of these 8 wheat genotypes harbored IN active P. syringae that were not virulent on either bread or durum wheat and for 1 of these wheat genotypes the strains of IN active P. syringae were virulent on only 1 of the 13 plant species on which pathogenicity was tested. For the wheat geno-types that had P. syringae on leaves in the field, bacteria were naturally transmitted to seed but dur-ing seed storage the bacterium could be detected on only half of the genotypes after 3 months of storage. To explore the possibility of enhancing the IN active microflora on leaves, we assessed the capacity of bacteria inoculated on seed to be transmitted to seed. The effectiveness of the trans-mission depended on an interaction of wheat genotype and bacterial strain. Overall, this work points to the possibility of selecting plants with the goal of changing their microflora for purposes other than resistance to plant disease and in this case for the purpose of contributing to processes that could favor rainfall.

Root-rot of cotton (Gossypium spp.) is one of the most important diseases in Upper Egypt. Isolation has been done from diseased cotton roots and seeds which were collected from 11 counties in Assiut province, Egypt. Identification procedures of the isolated fungi confirmed that the isolated fungi were for Fusarium solani, F. moniliforme and F. oxysporum and Rhizoctonia solani. Thirty six isolates of Fusarium spp. and 10 isolates of Rhizoctonia solani were tested for their pathogenicity on both Giza 80 and Giza 83 cotton seedlings to verify their virulence on seedlings. The pathogenicity test results have grouped the Fusarium spp. isolates into three groups; highly virulent that caused 91-100% mortalities; moderately virulent that caused 81-90% mortalities and low virulent that caused lower than 81.0% mortalities. Data also shows that, in general Giza 80 cotton cultivar was more susceptible for infection with Fusarium spp. when compared with Giza 83 cotton cultivar. In case of Rhizoctonia solani, data revealed that the infection percentage was significantly affected by isolates while cotton cultivars had no significant influence on infection. Four 10-mer primers (1:6-d, 2:6-d, 4:6-d and 5:6-d) were used in RAPD-PCR to determine the genetic variability between six isolates, one virulent and one less virulent, of F. moniliforme, F. oxysporum and F. solani. Our results showed that the primer 2:6-d clearly separated F. moniliforme, F. oxysporum and F. solani and proved to be quite powerful in distinguishing the three different species and isolates of Fusarium spp.

Published: May 2020

Forest plantations in Ethiopia are mainly exotic genera of Eucalyptus, Cupressus, Casuarina, Pinus and native Juniperus species. Plantations species have suffered at varying degrees of attack by disease causing agents, particularly Amhara region is among regions with plantation forests that have in recent years been subjected to attack by diseases in Ethiopia. Plantation trees in commercial stands, farmlands and woodlots were surveyed for diseases symptoms in 20 selected areas of Amhara and Tigray from May to June 2016.Leaf blight, leaf spot, tip blight and stem canker were the most common symptoms appeared during the survey period with leaf spot and stem canker the most prevalent. Tree samples showing clear disease symptoms were collected, surface sterilized, cultured and morphologically characterized for pathogen identification. A total of 42 isolates of fungi colonies were identified from samples collected of 20 localities. Morphological characterization of fungal isolates reveals, six fungal genera belonging to Alternaria, Dioplodia, Pestalotiopsis, Curvularia, Phoma, and Penicillium were the cause of the symptoms of the symptoms of the observed disease. Among the isolates 14 (33.3%) were Alternaria species, 15(37.7%) were Phoma species, and the remaining 13 isolates were Diplodia3(7.2%), Pestalopsis7(16.7%), Curvularia2(4.7%) and Penicillium1 (2. 4%).Based on the findings of the study Phoma lingam, Phoma glomerata, Alternaria alternata, genera of Curvularia, Pestalotiopsis, Penicillium, and Diplodia were found to be the cause of diseases of the tree plantations. Phoma and Alternaria species were the most prevalent isolates, showing a majority of symptoms observed on plantations were due to their co-infection. The pathogenicity test result of the research also confirms fungal isolates were the cause of the symptoms of the disease observed. The findings of this research enable to study and design appropriate management options for the future prevention and control of the diseases especially when there is prolonged environmental stress in the country.

Should azithromycin be used to treat COVID-19? A rapid review
Authors: Gbinigie Kome , Frie Kerstin 
Published: May 2020

BackgroundThere are no established effective treatments for COVID-19. While novel drugs are being developed, azithromycin has been identified as a candidate treatment in the interim.AimTo review the evidence for the effectiveness and safety of azithromycin in treating COVID-19.Design & settingA rapid review of the literature was conducted.MethodElectronic searches were conducted on 16 April 2020 of PubMed, TRIP, EPPI COVID Living Map, MedRxiv, GoogleScholar, and Google. In vivo and in vitro studies were included assessing the safety and effectiveness of azithromycin for treatment of COVID-19, and/or the activity of azithromycin against SARS-CoV-2. In vivo studies needed to include a comparator group.ResultsThree studies were identified, two in vitro and one in vivo, which were suitable for inclusion. All three were published as pre-prints. The in vitro studies revealed conflicting results, with one finding anti-SARS-CoV-2 activity for azithromycin alone, while the other found activity against SARS-CoV-2 only when azithromycin was combined with hydroxychloroquine. A small trial of 36 patients, with high risk of bias, found superior viral clearance in patients with COVID-19 treated with azithromycin and hydroxychloroquine combined, compared with hydroxychloroquine alone.ConclusionThere is no evidence to support the use of azithromycin for the treatment of COVID-19 outside of the context of clinical trials, unless it is used to treat bacterial super-infection. There is extremely limited evidence of a possible synergy between azithromycin and hydroxychloroquine. The adverse events profile of azithromycin in the context of COVID-19 has not yet been established. Well-conducted clinical trials are urgently needed in this area.

Published: May 2020

A high-performance anion exchange membrane (AEM) is critical for the development of alkaline fuel cell. In this work, AEMs with an interpenetrating polymer network (IPN) are synthesized. An electron microscope clearly reveals a highly efficient “ion channel” network, which is constructed with a small amount of cation exchange groups. This specially designed ion channel leads to extraordinary hydroxide conductivity (e.g., 257.8 mS cm
