among 160 samples collected from rice paddy of the guilan province including rice plant, seed, rhizospher, paddy's soil, paddy's water and sclerotium of the causal agent of rice sheath blight (rhizoctonia solani), 610 bacterial strains were isolated. 71 bacterial strains (11.64%) had the ability of inhibition mycelial growth fungus in dual culture test on pda medium. according to two characteri...

Klebsiella pneumoniae-associated pathology is largely mediated by neutrophilic inflammation. In this study, we administered Klebsiella pneumoniae to experimental guinea pig groups and the ELR-CXC chemokine antagonist CXCL8(3-72), ceftazidime, and dexamethasone to different groups, respectively. After 24 h, we assessed the animal's pulmonary inflammatory levels, including gross histopathology, a...

Abstract Stemphylium disease caused by vesicarium is an important that becomes obstacle in TSS production. The attacks can lead to seed harvest failure. In the field. associated with purple spot fungus Alternaria porri . purpose of this study was obtain biological agents were effective controlling S and A on tests carried out in-vitro laboratory planta field under a plastic shade. experimental ...

Abstract Pyricularia grisea (blast disease) and bacterial diseases resulted rice yield loss. Tolerant varieties seed-dressing are expected reduces the disease. This research was aimed to define effect of tolerant seed - dressing incidence blast diseases. Research conducted at endemic area in Yogyakarta Indonesia from November 2021 March 2022. The experiment designed randomized block with 2 fact...

Bacterial leaf blight is a serious disease of rice caused by Xanthomonas oryzae pv. (Xoo). The objective this study was to develop bioformulation Bacillus velezensis strain N1 using microencapsulation techniques through spray drying and then evaluate its performance in controlling bacterial under greenhouse conditions. Three formulations with different main carrier were studied the viability af...

AIMS Isolation of bacterial antagonist for use in the biological control of phytopathogenic fungi like rice blast fungus, Magnaporthe grisea, and to further purify and characterize the antifungal molecule produced by the antagonist. METHODS AND RESULTS Bacterial antagonist exhibiting highest antifungal activity against the rice blast fungus M. grisea was isolated from soil and identified as B...

The present study was undertaken to explore the possibility of using an indigenous strain of Pseudomonas fluorescens to manage one of the most devastating disease of the economically important brinjal crop, the bacterial wilt. The bacterial wilt caused by Ralstonia solanacearum has severly limited brinjal production in all parts of the world. In an attempt to evolve a biological management of t...

Background：Vibrio splendidusVs is an important aquaculture pathogen that can infect a broad host of marine organisms. In our previous study, an antagonistic bacterium Vibrio sp. V33 that possessed inhibitory effects on the growth and virulence of a pathogenic isolate V.splendidusVs was identified. O...
