Abstract : Helminthosporium tetramera was a pathogen of Saccharum Officinarum, isolated from diseased leaves Nashik district and used for the present study. Pathogen grown on Czapek-Dox liquid medium substituting or adding different carbon, nitrogen to study biomass production. The growth as dry mycelial observed 8th day incubation period. A grate extent variation nitrogen. Among carbon source,...

Recently we reported a role for compatible solute uptake in mediating bile tolerance and increased gastrointestinal persistence in the foodborne pathogen Listeria monocytogenes1. Herein, we review the evolution in our understanding of how these low molecular weight molecules contribute to growth and survival of the pathogen both inside and outside the body, and how this stress survival mechanis...

Rates of growth and reproduction of the pathogens that cause emerging infectious diseases can be affected by local environmental conditions; these conditions can thus influence the strength and nature of disease outbreaks. An understanding of these relationships is important for understanding disease ecology and developing mitigation strategies. Widespread emergence of the fungal disease chytri...

In biology phenotypic switching is a common bet-hedging strategy in the face of uncertain environmental conditions. Existing mathematical models often focus on periodically changing environments to determine the optimal phenotypic response. We focus on the case in which the environment switches randomly between discrete states. Starting from an individual-based model we derive stochastic differ...

Erratum Unfortunately, the original version of this article [1] contained an error. There are two references in the text to the threshold for defining VAP as greater than 10^4 colony forming units/ml. These should read greater OR EQUAL to 10^4 colony forming units/ml. The error is in the abstract and in the intervention sections. In the abstract, please replace: Patients with clinically suspect...

Long-term survival of Escherichia coli O157:H7 in soil and in the rhizosphere of many crops after fumigation is relatively unknown. One of the critical concerns with food safety is the transfer of pathogens from contaminated soil to the edible portion of the plants. Multiplex fluorogenic polymerase chain reaction was used in conjunction with plate counts to quantify the survival of E. coli O157...

Potentially hazardous foods require time/temperature control for safety. According to the U.S. Food and Drug Administration Food Code, most cheeses are potentially hazardous foods based on pH and water activity, and a product assessment is required to evaluate safety of storage >6 h at 21°C. We tested the ability of 67 market cheeses to support growth of Listeria monocytogenes (LM), Salmonella ...

some possible effects of exogenous application of salicylic acid (sa) and bacillus subtilis on infection potential of root and stem rot disease and on induction of resistance against this pathogen were investigated in laboratory and as well under greenhouse conditions. in vitro, the effectiveness of sa concentrations (2-8mm) on growth of b. subtilis was observed as negative, while sa applicatio...

soybean, glycine max, is susceptible to a large number of disease agents such as seedling and root pathogens that cause serious damages to this crop plant. one of these soil-borne pathogens is macrophomina phaseolina, the causal agent of charcoal root rot. in this study, two bacteria, pantoea agglomerans and bacillus sp. bin, and a fungus, trichoderma harzianum t100, as potential biocontrol age...
