Fusarium isolates obtained from diseased koa plants, rhizosphere soil and seeds/seedcoats may or may not be pathogenic on young seedlings under greenhouse conditions. This includes isolates of F. oxysporum, the putative cause of koa wilt/dieback disease in Hawaii. We tested ten Fusarium isolates, comprising four different species, for their pathogenic potential on Acacia koa seedlings under gre...

Background: Salmonella is one of the most important zoonotic agents known to infect humans and a wide range of animals, including poultry. Salmonella Infantis has been one of the 15 most frequently isolated serovars throughout the world. Despite its clinical importance, little is known about the molecular characteristics of S. Infantis strains from Iran. OBJECTIVES: The purpose of this study wa...

background: identification and quantification of mycotoxins produced by fusarium species are important in controlling fungal diseases. objectives: potential of zearalenone, butenolide and fusarin c production was investigated in five fusarium graminearum and five f. culmorum isolates at molecular level. materials and methods: presence of pks13, fg08079.1 and pks10 genes, associated with product...

BACKGROUND: Colibacillosis is one of the most prevalentdiseases in the world that causes multimillion-dollar annuallosses. OBJECTIVES: In order to evaluate molecular epidemiologyof some virulence associated factors in Escherichia coli,isolated from poultry, the presence of iut A, iss, hly F, omp T, iroN, afa, sfa (S)and pap G (II) were investigated by multiplex PCRassay. METHODS: Two hundred th...

Understanding genetic structure and status of genetic variation of Fasciola hepatica isolates from different hosts, has important implications on epidemiology and effective control of fasciolosis. Random amplified polymorphic DNA (RAPD-PCR) was used to study the genetic variation of F. hepatica in sheep and cattle. DNA was extracted from adult helminthes removed from livers of each infected ani...

despite routine vaccination programs against newcastle disease (nd), sporadic cases have occasionally occurred that remain a constant threat to commercial poultry. ten isolates of newcastle disease viruses (ndv) from infected broiler chicken cases were obtained from various locations in fars province during 2009-2011 and genetically analyzed using reverse transcription polymerase chain reaction...

objectives: the purpose of this study was to evaluate the effect of cuminum cyminum (c. cyminum) essential oil on the growth and fum1 gene expression of fumonisin-producing fusarium verticillioides (f. verticillioides) strains isolated from maize. materials and methods: all fungal strains were cultured on potato dextrose agar (pda) slopes at 30°c for 7 days. the antifungal activity was evaluate...

Pokkah boeng is a fungal disease that can cause serious yield losses in susceptible varieties. Pokkah boeng is caused by Fusarium, but there is some debate regarding the species involved. Previous research has revealed that some Fusarium species isolated from sugarcane could benefit the development of the stalk borer, Eldana saccharina, a serious pest of sugarcane in South Africa. The aim of th...

broomrape (orobanche spp.) is one of the most serious weed pathogen on many dicotyledonous plants such as tomato, cucumber, melon, tobacco and others. this weed parasite caused serious problem in tomato cultivation fields, especially in north west iran. some isolates of fusarium spp. and pseudomonas fluorescens are known as effective biological agents in biocontrol of this weed. in order to fin...
