Developmental biology and infection cycle of Sclerotinia sclerotiorum causing stem rot of carnation in India

Carnation (Dianthus caryophyllus L.) is a cut flower with greater stipulation in the world cut flower market. In India, carnations are cultivated under polyhouses in Nilgiris and Kodaikanal districts in the state of Tamil Nadu. Carnations cultivation is impeded by various diseases, among them stem rot caused by Sclerotinia sclerotiorum (Lib.) de Bary was found to be predominant in all varieties. Survey among...

Enhanced plant growth and/or nitrogen fixation by leguminous and non-leguminous crops after single or dual inoculation of Streptomyces griseoflavus P4 with Bradyhizobium strains

Plant growth-promoting endophytic bacteria have been widely used during crop production for either single inoculation or co-inoculation with nitrogen-fixing bacteria. The effect of Streptomyces griseoflavus P4 on growth of various crops was studied and the effects of co-inoculation on plant growth, nodulation and nitrogen fixation by soybean was investigated. Pot experiments were conducted in an environmentally...

Symbiotic effectiveness of different indigenous Bradyrhizobium strains on selected Rj-genes harboring Myanmar soybean cultivars

Many scientists are working to identify effective strains of rhizobia to increase nitrogen fixation and reduce nitrogen fertilizer application. Symbiotic nitrogen fixation of leguminous crops has become an alternative to nitrogenous fertilizer, due to its higher efficiency for nitrogen fixation. This experiment was conducted to select strains for improved nitrogen fixation of soybean (Glycine max L.). Bradyrhizobium...

Chromogenic agar media for rapid detection of Enterobacteriaceae in food samples

Recently, chromogenic media were used for rapid detection of pathogenic agents isolated from different materials (food, water and stool). Results of the present study indicated that specific and rapid identification of Enterobactiriaceae isolates from 46 food samples (egg, dairy products, meat, salads and cooked rice) as compared to conventional methods of biochemical test and plating selective media consume times, are...

Serogroups and antibiotics susceptibility pattern of avian pathogenic Escherichia coli strains responsible for colibacillosis in broiler breeding farms in the east of Algeria

In East Algeria, 100 Escherichia coli strains were isolated from livers and spleens of 120 broiler carcasses that presented colibacillosis lesions at autopsy. Serogrouping of these strains demonstrated that 83% of their serogroups belong to the most pathogenic serogroups of Avian Pathogenic Escherichia coli (APEC): O1 (14%), O2 (53%) and O78 (16%). In vitro susceptibility to antimicrobials of veterinary significance was...

Study of resistance mechanism in Enterobacter spp. with special reference to antimicrobials ceftazidime, moxifloxacin and nalidixic acid

Microbial resistance to antimicrobials is spreading all over the world making it difficult to treat diseases effectively. This study aims to understand the mechanism of resistance towards the antimicrobials Ceftazidime, Moxifloxacin and Nalidixic acid, by using resistant Enterobacter spp. and sensitive Enterobacter spp. While there was complete inhibition of growth of sensitive Enterobacter spp. at 8 µg/ml...

Salmonella Typhimurium, Enteritidis, Infantis and Derby in pasty dulce de leche

In order to evaluate the fate of Salmonella Typhimurium, Enteritidis, Infantis and Derby in pasty dulce de leche, aliquots of this sweet were experimentally contaminated with these pathogenic microorganisms at 102 bacterial cells per gram, and later analysed to evaluate microorganism count after storage for 0, 1, 2, 3, 5, 10 and 20 days. Salmonella Enteritidis was able to survive for up to 20 days in dulce de leche,...
