New pathogenicity test method

Next-generation sequencing (NGS) based population screening holds great promise for disease prevention and earlier diagnosis, but the costs associated with screening millions of humans remain prohibitive. New methods for population genetic testing that lower the costs of NGS without compromising diagnostic power are needed.

The sensitivity of some pathogenic bacteria used as test organisms to the new compounds 1–3 was determined. 1 showed appreciable antimicrobial activity with the diameter of inhibition zones ranging from 11 to 18 mm. 1 was active against the two multidrug resistant bacteria Acinetobacter baumannii and Staphylococcus aureus. Minimal inhibitory concentrations (MICs) of compound 1 were recorded for all the tested bacteria using the fluorescein diacetate method and the recorded MIC values ranged from 4 to 6 µM.

A survey was conducted in some districts of Upper Brahmaputra Valley Zone of Assam for most prevailing diseases in brinjal during the year 2015-16. Apart from the fruit rot disease of brinjal (Solanum melongena L.) caused by Phomopsis, Phytophthora, Alternaria etc., a new pathogen, Phoma exigua was observed. Initial symptom developed on the fruits as minute, slightly sunken spots, which later produced minute black bodies (pycnidia) scattered and immersed in the infected host tissues.

Seeds/grains may have the risk of association of a pathogen while exporting. They are, therefore, routinely tested under phytosanitary regulations to prevent pathogens movement along with maize grains/seeds into new territories and also affect seed quality. As there is an increased demand for the export of maize from India and maize seed borne fungal pathogens are concern of phytosanitary regulations which are detected through the different seed health testing methods.

Seed is the custodian of the genetic, potential of any cultivar and determines the limits of productivity in any cropping system. So awareness for seed health has increased among the growers, traders and consumers in recent years. A seed-borne inoculum not only secures the presence of a virulent strain of the pathogen along the seed but also favors the earliest possible establishment of the infection in seedlings along with possible threat of introduction of new physiological races/stains with seed.

Enterococci are Gram-positive, facultative anaerobic organisms, ovoid in shape, short chains, in pairs or single cells. The common enterococci-associated nosocomial infections are urinary tract infections, surgical wound infections and bacteremia. Resistance to vancomycin is now widely reported worldwide. In India, the prevalence of VRE has been reported as’ 8%, 5.5% and 23% in New Delhi, Chandigarh, and Mumbai. This study was done to detect the presence of vancomycin resistant enterococci (VRE) among the various samples in a tertiary care hospital.

Ship ballast water is a recognized medium for transfer and introductions of nonindigenous species. There is a need for new ballast water treatment methods that effectively and safely eliminate or greatly minimize movements of these species. The present study employed laboratory methods to evaluate the bactericidal efficacy of increased pH (pH 10.0–12.0) for exposure durations of up to 72 h to kill a variety of Gram-negative and Gram-positive bacteria including fish pathogens (Aeromonasspp., Yersinia ruckeri, Edwardsiella ictaluri, Serratia liquefaciens, Carnobacterium sp.
