Efficacy of fungicides, botanicals and bioagents against Rhizoctonia solani inciting leaf blight on turmeric (Curcuma longa L.)
Leaf blight caused by Rhizoctonia solani is one of the most serious diseases that cause damage to turmeric crop. Fifty percent disease incidence was observed in turmeric growing areas of Andhiyur (Erode district) and Mettur (Salem district) of Tamil Nadu, India. The antifungal efficacy of botanicals, bioagents and fungicides were tested against R. solani in vitro. It was observed that seed extract and oil cake of...

Biochemical factors and enzymes governing resistance in Indian mustard (Brassica juncea) against Sclerotinia stem rot (Sclerotinia sclerotiorum)
Four mustard cultivars possessing different degrees of resistance to Sclerotinia stem rot (Sclerotinia sclerotiorum) were used to study the biochemical and enzymatic basis of resistance. These include two moderately resistant cultivars (RGN-13 and RRN-505) and two susceptible cultivars (Bio-902 and T-59). Phenol content in all the mustard cultivars tested was found to increase at all three stages of inoculation, that...

Cloning and expression of Bacillus thuringiensis cry1Ia in Escherichia coli and its insecticidal activity
The crystal (Cry) proteins produced by Bacillus thuringiensis determine a particular strain's toxicity profile. This study was focused on cloning a cry1Ia gene based on amplicon restriction fragment length polymorphism (ARFLP) profile which would be helpful in developing new biopesticides with broader and higher spectrum of toxicity against Lepidoptera and Coleoptera insect pests. The present paper describes cry1Ia...

Soil microbial properties, growth and productivity of pearl millet (Pennisetum glaucum L.) as influenced by moisture management and zinc fortification under rainfed conditions
Pearl millet (Pennisetum glaucum L.) is an important crop in rainfed conditions and marginal land areas; it is grown under improper crop establishment and imbalanced fertilization. Proper moisture management with zinc fortification has potential to improve productivity, solve zinc malnutrition problem, maintain soil health and economic sustainability. The present study was conducted during 2012 and 2013 at IARI, New...

Resistance pattern of uropathogenic bacteria in males with lower urinary tract obstruction in Kumasi, Ghana
We described the antimicrobial susceptibility pattern of pathogenic bacteria causing urinary tract infections among males with lower urinary tract obstruction (LUTO) at the Komfo Anokye Teaching Hospital (KATH), Kumasi, Ghana. Between January and December 2009, a cross sectional hospital based study was conducted for 102 subjects. Patients presenting with symptoms of LUTO and who were on short admission (at most 48 h)...

Comparative studies on five culture media for bacterial isolation
The research made comparative studies on five media for bacterial isolation. This study aimed at capturing important comparative data in the various types of media for growth efficiency and specific bacteria identification in clinical microbiology. The sources of the samples were urine, nasal swabs and stool. The totality of 15 samples was plated monthly and 120 samples were studied during an eight month period. The...

Biodegradation study of γ-hexachlorocyclohexane using selected bacteria isolated from agricultural soil
Bacterial isolates RP-1, RP-3 and RP-9 were isolated from agricultural soil using enrichment culture technique and screened positive for lindane degradation. RP-1, RP-3 and RP-9 were found to utilize and degrade higher concentrations (100 ppm) of lindane. RP-1 and RP-3 showed 69.5 and 65% lindane degradation after 10 days of inoculation where as RP-9 degraded 62% of lindane after 15 days. The estimated Cl- ion release...

Action of sanitizers on Staphylococcus aureus biofilm on stainless steel and polypropylene surfaces
The interest of researchers in various areas has resulted in the investigation of different biofilm systems using a wide range of techniques. Biofilms are microbial communities consisting of mono or multi-species sessile cells, embedded in a matrix of extracellular polymers (exopolysaccharides-EPS) adhering to surfaces. In the food industry, the existence of biofilms is quite problematic, being responsible for the...

In vitro susceptibilities of the clinical isolate of Entamoeba histolytica to Euphorbia hirta (Euphorbiaceae) aqueous extract and fractions
Euphorbia hirta (Euphorbiaceae) has been used widely in traditional medicine as a treatment against infectious pathogens. This medicinal plant is also well known for its diverse biological activities. The present study aimed to evaluate the susceptibilities of the clinical isolates of Entamoeba histolytica to E. hirta aqueous extract, methanol fraction, methylene chloride fraction, and hexane fraction. The clinical...

Biodegradation of cassava root sieviate with enzymes extracted from isolated fungi
This study was carried out to investigate changes in proximate and chemical components of cassava root sieviates (CRS) treated with extracted enzymes obtained from (a) Aspergillus niger (An); (b) Rhizopus stolonifer (Rs); (c) Trichoderma viridae (Tv) and (d) Mucor mucedo (Mm) applied on autoclaved CRS at 250 ml/kg. Another treatment had a commercial enzyme Roxazyme G2G (RG2G) as the degrading agent. At the end of the...
