Abstract Sheath rot disease is one of the critical problems limiting rice production. Fusarium spp. pathogens that cause sheath and produce various mycotoxins. The study mycotoxins detection using specific primers their association to pathogenicity important in order comprehend types may occur this disease. objectives are investigate potential pathogen-related relation pathogenicity. This inclu...

The first barrier, when penetrating an insect host, encountered by microorganisms like fungi is insects cuticle; produce a wide variety of extracellular enzymes involved in the degradation protein, chitin, and lipids. main objectives were to assay enzymatic activity Cordyceps locustiphila anamorph, solid liquid medium at different temperatures also evaluate pathogenicity against South American ...

abstract brown rot is one of the fungal disease in the north of iran. symptoms on infected fruit in the initiation of infection appear as small dusky spots resembling peteca. then infected tissues were removed and cultured on the parph selective medium. based on morphological characters, growth rates, growth patterns and cardinal temperatures for growth, p. parasitica as a causal agent for mand...

The study of phylogenetic groups and pathogenicity island (PAI) markers in commensal Escherichia coli strains from asymptomatic Chinese people showed that group A strains are the most common and that nearly half of all fecal strains which were randomly selected harbor PAIs.

Assessment of eighty Fusarium proliferatum isolates obtained from maize, rice, sugarcane and onion using AFLP molecular marker separated the isolates into four distinct clusters according to their host’s. Isolates recovered from rice clustered in a distinct group. Isolates from sugarcane grouped in two distinct groups and isolates recovered from maize and onion clustered in a unit group. As wel...

Abstract Small GTPases of the Rab family play important roles in membrane trafficking and autophagy. Previous studies have shown that small GTPase Sec4 is involved vegetative growth, protein secretion, pathogenicity fungal phytopathogens. In this study, BcSec4, an ortholog yeast Sec4p protein, was characterized Botrytis cinerea . The ΔBcSEC4 mutant produces many abnormal conidiophores; it thus ...

This study aimed to survey, characterize, and identify the causal pathogen of tomato bacterial spots (TBS). The survey evaluated disease incidence severity on cultivated in Blue Nile State during autumn season 2015. surveyed sites were Alrosseris Aldmazein localities. Four farms selected from each locality. Symptomatic leaves collected sent plant pathology laboratory, Department Crop protection...

The effect of mutations of Newcastle disease virus (NDV) fusion (F) gene, hemagglutinin-neuraminidase (HN) gene, and phosphoprotein (P) gene and HN chimeras between the virulent Beaudette C and low virulence LaSota strains on pathogenesis and pathogenicity was examined in fully susceptible chickens. A virulent F cleavage site motif within a LaSota backbone increased pathogenicity and severity o...

After publishing results of a study that revealed diarrheagenic and emetic activity in 4-5-day old mice infected with Kudoa septempunctata (K. septempunctata) spores, the Korea Centers for Disease Control and Prevention reported 11 events of "Kudoa food poisoning" in 2015. The epidemiological design of the previous study was descriptive rather than analytical; therefore, this study aimed to fur...

various commercial vaccines for immunization of broiler chickens against infectious bursal disease (ibd) are available, so it would be appropriate to compare the pathogenicity and immune response of chickens to these vaccines. in this study the pathogenicity and serologic response of four ibd vaccines, cloned d78®, bursine-2®, bursimune® and cevac gambo-l®, were evaluated in specific pathogen f...
