Research ArticleOpen accessIn the abstractMolecular Characterization of Pseudomonas aeruginosa UPM P3 from Oil Palm RhizosphereBadri Fariman Azadeh, Sariah MeonProblem statement: Pseudomonas aeruginosa has been used in agriculture as biological agents. It has shown substantial control of a variety of soil-borne plant pathogens including Macrophomina phaseolina, Botrytis cinerea, Rhizoctonia solani, Colletotrichum truncatum, Pythium, Fusarium and others. Species aggregate of Pseudomonas aeruginosa strain UPM P3 was shown to have potential as a biocontrol agent against Ganoderma boninense, the causal agent … …American Journal of Applied Sciences, Vol. 6, Issue 11 · 30 Nov 2009 · 7,805 accessesView PDFCite
Research ArticleOpen accessIn the abstractMolecular Gender Determination of Ancient Human from Malay PeninsularZ.A. Shahrul Hisham, S. Sahidan, M. A.W. Rohaya et al.Problem statement: DNA samples from fourteen modern human bloods (seven males and seven females) and two ancient skeletal samples excavated from Kalumpang Island and Dungun, Peninsular Malaysia were subjected for molecular genders determination using specific primers of human AMELX and AMELY. Approach: A standard multiple PCR mixture with forward primer and either a human X-specific reverse primer for AMELX or … …American Journal of Applied Sciences, Vol. 6, Issue 10 · 31 Oct 2009 · 7,609 accessesView PDFCite
Research ArticleOpen accessIn the abstractMolecular Characterization of a Phytoplasma Associated with Coconut Yellow Decline (CYD) in MalaysiaN. Nejat, K. Sijam, S. N.A. Abdullah et al.Problem statement: Molecular methods have been used to detect phytoplasma in Malayan Red Dwarf (MRD) ecotype of coconut for the first time in Malaysia. Detect phytoplasma from coconut showing yellowing symptoms by nested PCR and Classify phytoplasma associated with disease of coconut palms, based on analysis of 16S rRNA gene operon sequences and virtual RFLP. Approach: Twenty MRD symptomatic palms … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 7,923 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of the Presence of Huanglongbing in Seeds and Movement of the Pathogen in Citrus reticulataHajivand Shokrollah, Thohirah Lee Abdullah, Kamaruzaman Sijam, Siti Nor Akmar AbdullahProblem statement: Huanglongbing (HLB) also known as citrus greening disease is a fastidious phloem-inhabiting bacterium in the genus Candidatus Liberibacter. Using universal primers, the 16S ribosomal DNA sequence of three strains of the bacterium were obtained by PCR. However there is very little information on seed transmission and HLB pathogen movement to find a way for control or reduce the … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 8,092 accessesView PDFCite
Research ArticleOpen accessIn the abstractPassive Transfer of HIV-1 Antibodies and Drug Resistant Virus during a Health Care Worker Accident: Implications for HCW Post-Exposure ManagementCarlos Fernando De Oliveira, Ricardo Sobhie Diaz, Abdallah Harmache et al.Problem statement: We studied in detail a case in which a nurse caring for an HIV-infected child suffered a deep-laceration accident with contaminated blood. Approach: The patient had been treated with zidovudine (ZDV) and the nurse became infected despite prophylactic use of ZDV initiated 2 h after the accident. A reactive anti-HIV-1/2 EIA and an indeterminate western blot (gp120/160 reactivity) … …American Journal of Infectious Diseases, Vol. 4, Issue 4 · 31 Dec 2008 · 6,876 accessesView PDFCite
Research ArticleOpen accessIn the abstractModification of Artificial Oliogosaccharides in Recombinant Escherichia coli CellsTomohisa Kato, Rie Mitsumori, Kenichi HatanakaArtificial oligosaccharides were modified using recombinant Escherichia coli cells that overexpress sialidase. Based on the principle of the saccharide primer method by using bacterial cells overexpressing enzymes related to oligosaccharide modification. Problem statement: It is very hard to obtain oligosaccharides, because they have complex and diverse structures with different linkage patterns and monosaccharide components. Approach: It had been known that … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 6,804 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetection of Chlamydophila abortus in Sheep (Ovis aries) in MexicoJuan Manuel Jiménez-Estrada, Marcos R. Escobedo-Guerra, Gabriel Arteaga-Troncoso et al.Chlamydophila abortus is one of the pathogens which induce abortion in small ruminants; this pathogen has a tropism for ruminant placenta and causes the disease commonly referred to as Ovine Enzootic Abortion (OEA). In Europe are estimated economic losses of around 20 million pounds a year by OEA. In the American Continent the disease has been reported only in Canada, … …American Journal of Animal and Veterinary Sciences, Vol. 3, Issue 4 · 31 Dec 2008 · 7,892 accessesView PDFCite
Research ArticleOpen accessIn the abstractEpitope Mapping of Dengue-Virus-Enhancing Monoclonal-Antibody Using Phage Display Peptide LibraryChung-I Rai, Huan-Yao Lei, Yee-Shin Lin et al.The Antibody-Dependent Enhancement (ADE) hypothesis has been proposed to explain why more severe manifestations of Dengue Hemorrhagic Fever and Dengue Shock Syndrome (DHF/DSS) occur predominantly during secondary infections of Dengue Virus (DV) with different serotypes. However, the epitopes recognized by these enhancing antibodies are unclear. Recently, antipre-M monoclonal antibody (mAb 70-21), which recognized all DV serotypes without neutralizing activity, were … …American Journal of Infectious Diseases, Vol. 4, Issue 1 · 31 Mar 2008 · 8,455 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeographic Distribution and Genetic Analysis of Physiological Racesof Setosphaeria turcica in Northern ChinaJingao Dong, Yongshan Fan, Xiumei Gui et al.Five hundreds and forty-six isolates of Setosphaeria turcica, the causal agent of Northern Corn Leaf Blight, were collected in 61 corn-growing locations throughout six provinces of Northern China during 2000-2002, to determine their pathogenicity on two sets of host differentials: OH43/Huangzao4, OH43Ht1Huangzao4Ht1, OH43Ht2/Huangzao4Ht2, OH43Ht3/Huangzao4Ht3 and OH43HtN/Huangzao4HtN. The isolates were grouped into 13 different physiological races (0, 1, 12, 3, 13, … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 8,809 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiochemical and Genetic Responses of Fungi to the Toxic Effect of Synthetic and Natural FungicidesMarÍa-Elena Báez-Flores, Rosalba Troncoso-Rojas, Martin-Ernesto Tiznado-HernándezThe objective of the present review is to analyze the molecular basis of fungicide resistance mechanism to both synthetic fungicides and the natural fungicides isothiocyanates. The review is focused mainly on Alternaria sp., but whenever available, similar studies in other fungi have been included. Fungal resistant strains to dicarboximide and phenylpyrrole fungicides have been found to contain mutations in one … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 8,122 accessesView PDFCite
