prevalencia de otitis parasitaria por Rhabditis sp en empresas ganaderas gyr en cordoba colombia
Revista U.D.C.A Actualidad & Divulgación Científica, 2016Co-Authors: Alfonso Calderon, Jose Cardona, Marlene I VargasAbstract:Dentro del genero Bos indicus, las razas Indubrasil y Gyr son mas susceptibles a la otitis parasitaria por Rhabditis bovis. El ganado Gyr, por sus caracteristicas zootecnicas en el Caribe colombiano, ha sido seleccionado para la produccion de leche. El objetivo de la presente investigacion fue determinar la prevalencia de otitis parasitaria por Rhabditis sp., en bovinos Gyr, en empresas ganaderas de Cordoba, Colombia. Se implemento un estudio descriptivo prospectivo de conveniencia, donde se recolectaron hisopados de cerumen de los conductos auditivos externos, de 136 bovinos. El criterio de diagnostico fue la observacion directa del movimiento en masa del cerumen y la visualizacion de los nematodos. La prevalencia de otitis parasitaria fue del 83,82%. Hubo diferencia significativa para las variables otitis clinicas, otorrea y olor. El diagnostico del parasito demuestra la existencia de Rhabditis sp., como causa de otitis parasitaria en ganados Gyr, en empresas ganaderas de Cordoba

an antimicrobial phthalate derivative from bacillus cereus the symbiotic bacterium associated with a novel entomopathogenic nematode Rhabditis oscheius sp
International Journal of Pharmacy and Pharmaceutical Sciences, 2015Co-Authors: K M Anju, C Mohandas, M M Archana, Bala NambisanAbstract:Objective: To isolate and identify the bioactive metabolites from the culture filtrates of a bacterium ( Bacillus cereus) symbiotically associated with a novel entomopathogenic nematode Rhabditis ( Oscheius ) species. Methods: The bacterium was cultured in three different media and the antimicrobial activity was determined by the well diffusion assay. The ethyl acetate extract of the cell free culture filtrate was then purified by silica gel column chromatography and thin layer chromatography. Identification of the active metabolite was done with HPLC, GC-MS and LC-MS. Results : The cell free culture filtrate of a nematode symbiotic bacterium showed both antibacterial and antifungal activities. Fermentation conditions were standardized and optimum antibacterial activity was observed in tryptic soy broth at 72 h of incubation at 30 °C. When the ethyl acetate extract was purified by silica gel column chromatography and thin layer chromatography, an active fraction was obtained which was subjected to HPLC analysis along with GC-MS and LC-MS leading to the identification of a major compound Bis (2-ethyl hexyl) phthalate. The compound was active against Gram positive bacteria Bacillus subtilis MTCC2756, Staphylococus aureus MTCC902, Gram negative bacteria Escherichia coli MTCC 2622 and fungi such as Aspergillus flavus MTCC27 7, Candida albicans MTCC183, Fusarium oxysporum MTCC 284, Rhizoctonia solani MTCC 4634. Conclusion : Bis (2-ethyl hexyl) phthalate was identified as one of the metabolites produced by a nematode symbiotic bacterium associated with a novel entomopathogenic nematode Rhabditis ( Oscheius ) species. Thus similar compounds isolated from novel entomopathogenic bacteria would pave the way for identifying new drugs for the pharmaceutical and agricultural sector.

nematicidal metabolite produced by symbiotic bacterium associated with a new entomopathogenic nematode Rhabditis oscheius sp
Indian journal of nematology, 2015Co-Authors: K M Anju, C Mohandas, I Deepa, M M Archana, Bala NambisanAbstract:Entomopathogenic nematodes (EPN) and their symbiotic bacteria are well-known as biological control agents and are found to produce a wide range of bioactive secondary metabolites. Studies carried out at the Central Tuber Crops Research Institute (CTCRI) on entomopathogenic nematodes resulted in the identification of novel EPN belonging to Rhabditis (Oscheius) species. This study reports the purification of a nematicidal metabolite from the symbiotic bacterium associated with Rhabditis (Oscheius) species. The crude culture filtrate and ethyl acetate extracts of this nematode symbiotic bacterium showed significant nematicidal activity against Meleidogyne incognita. The bacterium was cultured in tryptic soy broth at 72 hours of incubation at 30°C. The ethyl acetate extract was purified by silica gel column chromatography and thin layer chromatography. HPLC combined with GC-MS and LC-MS led to the identification of the major compound as Bis (2-ethyl hexyl) phthalate. Thus this nematode and the associated bacteria have the potential to be developed as nematicidal agent against plant parasitic nematodes.

isolation of proline based cyclic dipeptides from bacillus sp n strain associated with rhabitid entomopathogenic nematode and its antimicrobial properties
World Journal of Microbiology & Biotechnology, 2013Co-Authors: Nishanth Kumar, Bala Nambisan, C Mohandas, D Soban R Kumar, Ravi S LankalapalliAbstract:Entomopathogenic nematodes (EPN) are well-known as biological control agents and are found to have associated bacteria which can produce a wide range of bioactive secondary metabolites. We report herewith isolation of six proline containing cyclic dipeptides cyclo(d-Pro-l-Leu), cyclo(l-Pro-l-Met), cyclo(d-Pro-l-Phe), cyclo(l-Pro-l-Phe), cyclo(l-Pro-l-Tyr) and cyclo(l-Pro-d-Tyr) from ethyl acetate extract of the Luria Broth (LB) cell free culture filtrate of Bacillus sp. strain N associated with a new EPN Rhabditis sp. from sweet potato weevil grubs collected from Central Tuber Crops Research Institute farm. Antimicrobial studies of these 2,5-diketopiperazines (DKPs) against both medicinally and agriculturally important bacterium and fungi showed potent inhibitory values in the range of μg/mL. Cyclic dipeptides showed significantly higher activity than the commercial fungicide bavistin against agriculturally important fungi, viz., Fusarium oxysporum, Rhizoctonia solani, and Pencillium expansum. The highest activity of 2 μg/mL by cyclo(l-Pro-l-Phe) was recorded against P. expansum, a plant pathogen responsible for causing post harvest decay of stored apples and oranges. To our knowledge, this is the first report on the isolation of these DKPs from Rhabditis EPN bacterial strain Bacillus sp.

impact of beef extract and six carbon source on antifungal metabolites production by bacterium associated with entomopathogenic nematode against fusarium oxysporum
Archives of Phytopathology and Plant Protection, 2013Co-Authors: Sasidharan Kumar Nishanth, Bala Nambisan, Chellapan MohandasAbstract:A specific symbiotic Bacillus species isolated from a rhabditid entomopathogenic nematode, Rhabditis (Oscheius) sp., was found to produce a number of bioactive compounds. The present study was conducted to determine the effect of six different carbon sources in combination with beef extract on the production of antifungal substances by Bacillus sp. The yield of crude antimicrobial substances and antimicrobial activity against the test microorganism also differed significantly when the carbon sources in the fermentation media were changed. The highest yield was recorded for fructose plus beef extract (956 mg/l). The antifungal activity was significantly high in beef extract plus maltose (21 ± 1.5 mm) followed by beef extract plus glucose and beef extract plus fructose. Antifungal activity was significantly reduced in beef extract plus lactose and sucrose. High pressure liquid chromatography analysis of the crude antimicrobial substances revealed different peaks with different retention times indicating tha...

influence of carbon and nitrogen sources on antifungal metabolite production by bacterium associated with entomopathogenic nematode against penicillium expansum
Archives of Phytopathology and Plant Protection, 2013Co-Authors: Kumar S Nishanth, Bala Nambisan, R Ramya, Chellapan MohandasAbstract:A specific symbiotic Bacillus sp. isolated from a rhabditid entomopathogenic nematode, Rhabditis (Oscheius) sp. was found to produce large number of bioactive compounds. The present study was conducted to determine the effect of carbon and nitrogen sources for the production of antimicrobial substances by Bacillus sp. The yield of the crude antimicrobial substances and antimicrobial activity against the test micro-organism also differed significantly when carbon and nitrogen sources in the fermentation media were changed. The antifungal activity was significantly high in yeast extract plus fructose (46.5 ± 2.12 mm) followed by yeast extract plus maltose, beef extract plus fructose and meat infusion plus glucose. High pressure liquid chromatography analysis of the crude antimicrobial substances revealed different peaks with different retention time indicating that they produced different compounds. When the carbon source was not included in the fermentation media, the antimicrobial production was substanti...
