| 1 | Contribution of microbial phytases to the improvement of plant growth and nutrition: A review显示文摘Phytases belong to the class of phosphohydrolases that begin the step-wise hydrolysis of phosphates from phytates. Phytates are a derivative of myo-inositol, which is the primary storage form of organic phosphorus in plant cells. Phytase has been used globally to diminish phosphorus pollution and to enhance nutrition in monogastrics. In this review, the classification, sources, and diversity of microbial phytases, and their practical applications, as well as supplementation of the soil with transgenic and wild types of microbial strains, which can release phytase to enhance phosphorus availability for plant uptake and reduce the need for fertilizers, are discussed. The overexpressed microbial phytases in transgenic plants enhance the growth capacity of co-cultivated plants and can therefore be employed in agricultural and biotechnological practices, such as intercropping. The introduction of phytases into the soil for improved plant growth and enhanced crop yield can be accomplished without extra cost. A diverse group of photoautotrophic microalgae can synthesize phytase and will likely be useful in many human food and animal industries. | Bijender SINGH Ines BOUKHRIS PRAGYA Vinod KUMAR Ajar Nath YADAV Ameny FARHAT-KHEMAKHEM Anil KUMAR Davender SINGH Monia BLIBECH Hichem CHOUAYEKH Othman AALGHAMDI | 2020 | Pedosphere2020，30，3： | 2 |

| 3 | Evaluation of berries of Phytolacca dodecandra for growth inhibition of Histoplasma capsulatum var.farciminosum and treatment of cases of epizootic lymphangitis in Ethiopia显示文摘Objective:To evaluate the berries of Phytolacca dodecundra(P.dodecandra) for its effect on Histoplasma cupsulatum var.farciminosum(HCF) and for the treatment of cases of epizootic lymphangitis(ELi.Methods:Samples were collected from un-ruptured nodules of cases of EL at Debre Zeit and Akaki(central Ethiopia).Mycologieal culture and isolation of HCF were performed at the Akliln Lemma Institute of Pathobiology.Phytochemical screening was done for n-butanol extract of P.dodecandra to delect alkaloids,saponins,phenolic compounds and flavonoids.The minimum inhibitory concentrations(MICs) and minimum fungicidal concentrations(MFCs) ol aqueous and n-butanol extracts of P.dodecandra against FICF were determined by agar dilution assay.For the in vivo trial.5%simple ointment was prepared from n-butanol extract and applied topically to 24(twelve early and twelve moderate) cases of F.L.Results:Phytochemical screening showed that n-butanol extract ol P.dodecandra was positive lor alkaloids.saponins and phenolic compounds but negative for flavonoids.The MFCs of n-butanol and aqueous extracts of P.dodecandra were(0.039%-0.078%) and(0.625%-1.250%),respectively.The MFCs of n-butanol and aqueous extracts of P.dodecandra were(0.078%t-0.156%)and(1.250%-2.500%),respectively.The MIC and MFC of ketoconazole(positive control) was(1.200×10^(-5)%-2.500×10^(-5)%) and(5.000× 10^(-5)%-1.000×10^(-4)%),respectively while growth was observed on free medium(negative control).From the total of 24 treated cases of EL,14(58.3%) responded lo treatment;however,10(41.7%) did not respond to treatment.There was no significant difference in the degree of response to treatment between early and moderate cases(χ~2=0.086:P=0.408.Conclusions:It can be concluded that n-butanol extract of P.dodecandra demonstrates antifungal effects while the aqueous extract shows no antifungal activity. | Negesse Mekonnen Eyasu Makonnen Nigatu Aklilu Gobena Ameni | 2012 | Asian Pacific Journal of Tropical Biomedicine2012，2，7： | 2 |

| 5 | High helminthic co-infection in tuberculosis patients with undernutritional status in northeastern Ethiopia显示文摘Background:Tuberculosis and parasitosis are the widely distributed diseases in Ethiopia with the leading cause of mortality and morbidity,respectively.There has been no information on the status of co-infections of tuberculosis and parasitosis in Oromia Zone of Amhara Region and South Wollo,Ethiopia.Hence,this study primarily focuses on determining the status of tuberculosis and parasitosis co-infections and associated factors.Methods:The study was conducted in Oromia Special Zone of the Amhara Regional State and South Wollo Zone,northeastern Ethiopia from April 2015 to January 2017.Tuberculosis cases confirmed by health personnel at the health institutions were the source of the study sample.In a cross-sectional study 384 smear positive pulmonary and extra-pulmonary tuberculosis cases were recruited.Faecal specimens provided by the study participants were examined for parasitic co-infections using direct saline microscopic test,Kato-Katz and concentration techniques.Nutritional status was determined using body mass index and mid-upper arm circumferences.Data were analyzed using descriptive statistical methods and Pearson chi-square.Results:Tuberculosis and parasitosis co-infection prevalence was 10.8%,and the proportion of intestinal helminths accounted for 9.7%while intestinal protozoa accounted for 1.9%.Cases with single parasitic infection was 89.3%among co-infected individuals.Co-infection of both disease was not significantly associated with gender and age(P>0.05).The prevalence of undernutrition was 58.6%as determined using body mass index and 73.0%as determined using mid-upper arm circumference with no significant association with gender.Among all forms of tuberculosis cases(384)screened for the study,the bacterial positivity was relatively more common in males(55.5%)than females(44.5%).Tuberculosis lymphadenitis was found to be the most prevalent(85.9%)form of extrapulmonary tuberculosis with cervical adenopathy(75.3%)being the commonly existing disease.Conclusions:The rate of helminthic co-infection is predominantly high than that of intestinal protozoa.Single parasitic co-infection was more common than double or multiple co-infections.Both body mass index and midupper arm circumference anthropometric parameters revealed greater risk of undernutrition in tuberculosis patients.Thus,screening and prompt treatment of parasites in tuberculosis patients and a support of nutritional supplementation for malnourished tuberculosis patients should be further studied which might enhance the disease treatment and minimize the risk of its complexity. | Fikru Gashaw Samuel Bekele Yalemtsehay Mekonnen Girmay Medhin Gobena Ameni Berhanu Erko | 2019 | Infectious Diseases of Poverty2019，8，5： | 1 |
