the severe epidemics of fusarium head blight (fhb) as a devastating disease of cereal crops has occurred on wheat in north and northwest iran in recent years. the in vitro production of deoxynivalenol (don) was qualitatively evaluated in 41 fusarium isolates collected from wheat heads associated with the scab disease, in moghan area/northwest iran. infected wheat heads were collected during 200...

Wheat is one of the most important cultivated cereals in Uruguay for human consumption; however, when harvest yields are low, wheat is usually used in ensiling for animal feeding. Ensiling is a forage preservation method that allows for storage during extended periods of time while maintaining nutritional values comparable to fresh pastures. Silage is vulnerable to contamination by spoilage mol...

Fusarium graminearum (teleomorph Gibberella zeae) is an important plant pathogen that causes diseases on roots, stems, fruits, and seeds of diverse families. The fungus obtains nutrients through saprotrophic parasitic relationships. Mycotoxins produced by F. graminearum, which can be found in contaminated grains flours, constitute a threat to human animal health. aim this study was infer biolog...

We developed a molecular assay to detect predation on Anopheles gambiae sensu lato (s.l.) mosquitoes. This intergenic spacer ribosomal DNA polymerase chain reaction assay and restriction enzyme analysis uses An. gambiae-specific primers to detect mosquito DNA in the DNA extracts from whole invertebrate predators, which enables identification of species (An. gambiae s.s. versus An. arabiensis) a...

In order to determine the causal agents of Fusarium head blight, during 2015–16, wheat heads with disease symptom were collected from 10 and six main wheat production areas of Golestan and Mazandaran provinces (N Iran), respectively. A total of 431 Fusarium isolates were obtained belonging to nine Fusarium species based on their morphological characteristics. Fusarium graminearum species comple...

Borrelia miyamotoi sensu lato, a relapsing fever Borrelia sp., is transmitted by the same ticks that transmit B. burgdorferi (the Lyme disease pathogen) and occurs in all Lyme disease-endemic areas of the United States. To determine the seroprevalence of IgG against B. miyamotoi sensu lato in the northeastern United States and assess whether serum from B. miyamotoi sensu lato-infected persons i...

We investigated the nucleotide variation of a conifer, Cryptomeria japonica, and the divergence between this species and its closest relative, Taxodium distichum, at seven nuclear loci (Acl5, Chi1, Ferr, GapC, HemA, Lcyb, and Pat). Samples of C. japonica were collected from three areas, Kantou-Toukai, Hokuriku, and Iwate. No apparent geographic differentiation was found among these samples. How...
