newcastle disease virus (ndv) was isolated and identified for the first time from a flock of japanese quail suspected to nd in iran. birds of the flock aged variously, and some of them died from the disease. loss of appetite, weakness and decrease in egg production, diarrhea and nervous symptoms were the main clinical signs in the birds. hemorrhagic lesions of the intestinal tracts and proventr...

Yersinia enterocolitica serotype O:21, biotype 3 (Wauters) was isolated from the appendix and stool of a 7-year-old girl. The same organism was later isolated in pure culture from pus from a postoperative wound infection in this patient. She developed a significant serological response (titer of 800). There was thus strong clinical evidence of pathogenicity associated with this rather uncommon ...

pathogenicity and genetic variability of 13 fusarium oxysporum isolates collected from sugar beet field of six provinces of iran during 1999- 2008 were evaluated. pathogenic variability of the isolates was determined using a root-dip assay in spore suspension in test tubes for four- week plants. the isolates were classified into strong and weak pathogenic groups. a total of 15 rapd primers were...

This work was aim to evaluate the pathogenicity and level of aggressiveness ten strains Fusarium oxysporum f. sp. elaeidis (Foe) on palm oil seedlings susceptible vascular wilt. For this purpose, radial growth, sporulation morphological characteristics Foe from farm Cameroon Development Corporation (South-west) were studied in vitro. In addition, 500 wilt aged 5 months distributed a randomized ...

Soy is an important oilseed crop in Kazakhstan. However, its yield significantly reduced due to increase the development of fungal diseases with soil infection. This study aims identify root rot pathogen soybean varieties Western Kazakhstan and assess pathogenicity. Samples roots determine were selected at experimental plots Aktobe agricultural station 2021. Genetic analysis isolates observed o...

In March 2014, a kohlrabi stem rot sample was collected from the cold storage room of Daegwallyong Horticultural Cooperative, Korea. White and fuzzy mycelial growth was observed on the stem, symptomatic of stem rot disease. The pathogen was isolated from the infected stem and cultured on potato dextrose agar for further fungal morphological observation and to confirm its pathogenicity, accordin...
