Eco- friendly strategies for management of Fusarium wilt of Pisum sativum L.

The efficacy of different microbes for their antagonistic ability was determined in-vitro against Fusarium oxysporum f. sp pisi by dual culture method. T. viride andPseudomonas fluorescens-I exhibited maximum antagonistic activity in vitro. In-vivo T. viride and Pseudomonas fluorescens resulted in maximum reduction of seed rot root and wilt (Fusarium...

Efficacy of dichlorvos+tetramethrin, Bougainvillea glabra, potassium chloride and Bacillus thuringiensis on Tribolium castaneum

The present research was based on determining the effect of dichlorvos + tetramethrin (3.1% emulsifiable concentrate, EC), Bougainvillea glabra, potassium chloride and Shaf IBacillus thuringiensis alone or in combination against Tribolium castaneum (Jaculin Du val.) adults and larvae.  Bt was isolated from samples, cultured on different media by applying microbial techniques and then...

Studies on the bacterial flora and pathologic lesions of caprine pneumonic lungs in Maiduguri North-Eastern Nigeria

The study was conducted in Maiduguri, North - Eastern Nigeria to assess the bacterial flora, gross and histopathological lesions of caprine pneumonic lungs. A total of 500 caprine pneumonic lung samples from goats slaughtered at the Maiduguri municipal abattoir were collected and examined. The results of the bacterial isolates showEscherichia coli (86.6%), Mannheinmia haemolytica (54.4%), Klebsiella...

Comparative survival of acid-adapted Salmonella Heidelberg, Salmonella Montevideo and Salmonella Tennessee in simulated gastric fluid

This study compared the ability of Salmonella Heidelberg, Salmonella Montevideo andSalmonella Tennessee to adapt to acidic conditions (pH 6.0 and 5.0) and subsequently to survive in simulated gastric fluid (pH 1.5). Cells adapted at pH 5.0 showed lower maximum growth rates than non-adapted and adapted cells at pH 6.0. The resistance of acid adapted S. Heidelberg...

Laboratory study of the effects of nitrification inhibitors on the abundance of ammonia-oxidizing bacteria and archaea in a Hap-Ustic Luvisol

Nitrification inhibitors (NIs) could slow down nitrification by suppressing ammonia oxidizers. Responses of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) to NIs were studied in grassland soil and acidic agricultural soil, but we know little about effects of NIs and NIs per se on AOA and AOB abundance in neutral agricultural soil. We aimed to investigate the effects of NIs, dicyandiamide...

Potential role of Nostoc muscorum and Nostoc rivulare as biofertilizers for the enhancement of maize growth under different doses of n-fertilizer

Strains of the genera Nostoc (7 species) and Phormidium (one species) were isolated from soil. Cyanobacterial isolates were tested for their ability to form associations with the roots of wheat seedlings grown in liquid culture as well as fixing of atomospheric N2. The present study revealed that Nostoc colonization of wheat was tight association whilephormidium colonization was...

Effect of media on growth and antagonistic activity of selected Trichoderma strains against Ganoderma

This study was conducted to determine the effect of culture media on the growth rate and antagonistic activity of Trichoderma harzianum strain 1132 and Trichoderma virens strain 128 in Ganoderma sp. The two growth media evaluated were potato sucrose agar (PSA) and potato dextrose agar (PDA). Growth rate was determined by the rate of spore density production. Significantly higher spore...

New molecular diagnosis method combined with nucleic acid sequence-based amplification and probe amplification in rapid detection of Enterovirus 71

In this study, a new molecular diagnosis assay for rapid detection of virus RNA was established, which combined nucleic acid sequence-based amplification (NASBA) with rapid isothermal detection assay (RIDA). Using this method, we could rapidly identify Human enterovirus 71 RNA with high sensitivity and specificity; the detection limit of the new method was 102copy/ml. The whole assay was processed in one tube and the...

The survival of Escherichia coli O157:H7 and Salmonella Typhimurium in black mulberry (Morus nigra) juice

Black mulberry juice gains popularity based on the high antioxidant content of it. However, acid adapted pathogens in fresh fruit juice are strong threats for food safety. The survival and growth patterns of Escherichia coli O157:H7 (932) and Salmonella Typhimurium (NRRL B 4420) in black mulberry (Morus nigra) juice were determined in this study. The mulberry juices were differently concentrated...
