Antimicrobial activities and phytochemical composition of extracts of Ficus species: An over view
This paper reviews the antimicrobial research undertaken on Ficus species. Antimicrobial methods [disc and well diffusion, minimum inhibitory concentration (MIC), minimum bacterial concentration (MBC)] were used to evaluate the different extracts. The majority of published articles use MIC assays for antimicrobial determination. An overview is given on the activities; extracts, compounds or...

Challenges and future prospects for Dengue vector control
Dengue is a significant public health issue in urban and suburban areas. It is a viral disease transmitted by Aedes mosquitoes. Due to lack of specific antiviral treatment or vaccine against dengue, vector control presently appears to be the only effective method for dengue prevention and control. Various methods are in use for vector control depending upon geography and climatic conditions of the...

Genetic characterization of Fusarium oxysporum isolated from guava in northern India
Fusarium oxysporum f. sp. psidii is a causal agent of wilt disease of guava in subtropical regions globally. The production of guava fruit is affected by wilt disease thus, there is a need to develop molecular markers for accurate, rapid, specific and sensitive diagnosis ofF. oxysporum. A set of species-specific primers were developed for amplification of the internal transcribed...

Screening, identifying and medium optimization of a lipase-producing filamentous fungus from soil for high chiral resolution of 1-phenylethanol
The kinetic resolution of racemates by biocatalysis is one of the major routes to manufacture optically pure compounds. Lipase-producing microorganisms were screened from soil for chiral resolution of 1-phenylethanol in the study. One microorganism with high chiral resolution ability was isolated and identified as Rhizopusstolonifer by the sequence similarity analysis and construction of...

Purification and stability characteristics of an extracellular alkaline serine protease from a newly isolated Stenotrophomonas maltophilia strain D2
One bacterial strain D2 (GenBank accession number CGMCC No. 1868) with a taxonomic affiliation to Stenotrophomonas maltophilia was isolated from the QINGDAO coast in China and can produce extracellular alkaline protease. In this study, the alkaline protease was purified 4.9-fold by a four-step purification protocol with 33% activity recovery and was designed S....

Epidemiological investigation on swine intestinal parasites in Shaanxi province, China
The present investigation was undertaken to determine the prevalence of common intestinal parasites in domestic pigs in Shaanxi province of China between May 2011 and February 2012. A total of 1339 pig fecal samples were collected from pre-weaners (252),growers (360), fatteners (417), breeding sows and boars (310) in 9 farms located in 8 counties/districts. Among them, 387 fecal samples were...

Assessing Listeria monocytogenes hly A genome in pregnant women with spontaneous abortion using PCR method in Yasuj, south west of Iran
Listeriosis is a disease which is caused by Listeria monocytogenes bacterium that endangers lives of infants, pregnant women, elderly and patients with suppressed immunity system. The aim of this study was to assess the prevalence of L. monocytogenes in pregnant women with spontaneously abortion and isolating it using polymerase chain reaction method in Yasuj. In a cross-sectional study,...

Parasporal crystal proteins of Bacillus thuringiensis strain BT6, originating from the faeces of Sika Deer, demonstrate anticoccidial activity against Eimeria tenella in chickens
The parasporal crystal proteins (Cry) of Bacillus thuringiensis (Bt) strain BT6, which was isolated from Sika Deer faeces, exhibited a similar effect with diclazuril for controlling the infection with Eimeria tenella in chickens. A far more considerable body weight gain was found in the chickens treated with BT6 Cry proteins, as compared to chemical drug-treated groups, infected-untreated...

Pathogenicity of mycoflora of tip-rot disease of Aloe vera (Syn Aloe barbadensis Miller), a common medicinal plant In Abraka, Delta State, Nigeria
The mycoflora associated with tip-rot disease of Aloe vera (Syn, Aloe barbadensis Miller) and their pathogenicity was investigated in Abraka, Delta State. Fungi associated with diseased plants were isolated and identified as Mucor hiemalis, Fusarium oxysporium, Pestalotia psidii, Cladosporium herbarum and Heteropatella alpina, with occurrences by 46.22, 20.17, 13.45, 10.92...

Bacteriology of chronic maxillary sinusitis in Jeddah, Saudi Arabia
The objective of the present study was studying the prevailing bacterial etiology of Chronic Maxillary Sinusitis (CMS) in different age groups, to evaluate the impact predisposing factors to chronicity and to estimate the susceptibility of the isolated microorganisms to commonly used antimicrobial agents. This study was carried out on 103 patients (60 males and 43 females) in age ranged from (12 to 67 years)...

Microscopic study of Alternaria brassicae infection processes in Brassica juncea cultivars by drop plus agarose method
Alternaria blight caused by Alternaria brassicae (Berk) Sacc. is one of the most serious diseases of Indian mustard [Brassica juncea (L.) Czern and Coss.] grown as edible oilseed crop in India. Poorly characterized tolerance mechanisms against this pathogen further confirm the strategies that can be undertaken to design durable resistance or effective disease control measures. The...

Screening of alkaline proteases in Phanerochaete chrysosporium grown in non-lignocellulose medium
Phanerochaete chrysosporium is a well known organism which produces extracellular proteases. In this study, the two principal extracellular alkaline proteases produced by submerged batch cultures of P. chrysosporium were characterized by SDS-PAGE and zymography. The protease activity was observed from the third day of incubation consisted of two protein bands ranging in size of 33 and 40...
