| 1 | The effect of extracts of Selaginella involvens and Selaginella inaequalifolia leaves on poultry pathogens显示文摘Objective:To investigate the antimicrobial activity of some commonly available herbs against poultry pathogens such as Escherichia coli(E.coli) and Pseudomonas species isolated from poultry litter.Methods:The extracts of Selaginella involvens and Selaginella inaequalifolia were tested against E.coli and Pseudomonas isolated from poultry litter by the agar diffusion method.Results:Results indicated that different plant extracts showed inhibitory effects against E.coli(8-13 mm ) and Pseudomonas(6.5-13 mm).The four different extracts of Selaginella involvens and Selaginella inaequalifolia showed similar levels of antimicrobial activity on E.coli. Conclusions:The antimicrobial activities of all the four plant extracts are comparable and their potential as alternatives in the treatment of infections by these microorganisms were present in the poultry litter.Susceptibility testing is conduced on isolates using drugs selected on the basis of their importance to human medicine and use in poultry production. | Haripriya Duraiswamy Selvan Nallaiyan Jeyakumar Nelson Periasamy Rathina samy Marimuthu Johnson Irudayaraj Varaprasadam | 2010 | Asian Pacific Journal of Tropical Medicine2010，3，9： | 8 |
| 2 | The effect of leaves extracts of Clitoria ternatea Linn against the fish pathogens显示文摘Objective:To investigate the antimicrobial activity of Clitoria ternatea(C.ternatea) against the fish pathogens viz.,Pseudomonas aeruginosa(P.aeruginosa),Escherichia coli(E.coli),Klebsiella pneumonia(K.pneumonia),Bacillus subtilis(B.subtilis),Aeromonas formican(A.formicans)s, Aeromonas hydrophila(A.hydrophila) and Streptococcus agalactiae(S.agalactiae )isolated from diseased Tilapia(Oreochromis niloticus).Methods:The extracts of C.ternatea was tested against P.aeruginosa,E.coli,K.pneumonia,B.subtilis,A.formicans,A.hydrophila and S.agalactiae by the agar well diffusion method.Results:Different extracts of C.ternatea showed inhibitory effects against P.aeruginosa,E.coli,K.pneumonia,B.subtilis,A.formicans,A.hydrophila and S. agalactiae.Ethyl acetate extracts of C.ternatea showed maximum of zone of inhibition against A. formicans(18 mm),A.hydrophilia(19 mm),B.subtilis(19 mm) and P.aeruginosa(21 mm) next to that ethanol extract of C.ternatea showed A.formicans(18 mm) and E.coli(14 mm) followed by Acetone extract showed maximum zone of inhibition S.agalactiae(19 mm) and K.pneumonia(17 mm).Conclusions:The antimicrobial activities of all the four plant extracts are comparable and their potential as alternative in the treatment of infectious by these microorganisms was present in the fish.Susceptibility testing is conducted on isolates using drugs selected on the basis of their importance to human medicine and use in fish production. | Selvamaleeswaran Ponnusamy Wesely Ebenezer Gnanaraj Johnson Marimuthu Antonisamy Velusamy Selvakumar Jeyakumar Nelson | 2010 | Asian Pacific Journal of Tropical Medicine2010，3，9： | 4 |
| 3 | Biochar can Increase Chinese Cabbage(Brassica oleracea L.)Yield,Decrease Nitrogen and Phosphorus Leaching Losses in Intensive Vegetable Soil显示文摘There are few evidences on the effect of biochar on vegetable yield,nitrogen(N)and phosphorus(P)leaching losses under intensive vegetable production soil.The current field plot scale study evaluated responses of Chinese cabbage(Brassica oleracea L.)yield,N and P leaching losses using five N treatments of common N application rate according to local farmers’practice(N100%),reducing 20%or 40%N fertilizer(N80%and N60%),and reducing 40%N fertilizer but incorporating 10 or 20 t/ha biochar(N60%+BC10 and N60%+BC20).Results showed that N80%and N60%decreased both the cabbage economic and leaf yields by 6.8%-36.3%and 27.4%-37.7%,respectively.Incorporation of biochar with reduced N fertilizer rates improved the cabbage yield,in particular the N60%+BC20 matched the yield that observed in N100%treatment.Enhanced N and P uptake capacities of cabbage shoot probably contributed the higher vegetable production under both biochar amendment schemes.Biochar application mitigated the NH_(4)^(+)-N and total P leaching losses by 20%-30%and 29%-32%,respectively,compared with their counterpart treatment N60%.Nevertheless,biochar exerted no influence on the NO_(3)^(-)-N leaching.In addition,soil organic matter content was recorded with 7.4%-28.7%higher following 10-20 t/ha biochar application.In conclusion,biochar application can increase economic yield of cabbage via increasing N and P use efficiency,decrease N and P leaching losses,and improve soil quality in an intensive vegetable production system. | Haijun Sun Paramsothy Jeyakumar Hongdong Xiao Xuewen Li Jiayou Liu Min Yu Prabal Bir Jung Rana Weiming Shi | 2022 | Phyton-International Journal of Experimental Botany2022，91，1： | 3 |
