Pathogenicity and anastomosis groups of seven Rhizoctonia-like isolates obtained from infected pistachio (Pistacia vera L.) seedlings were determined, in the central district Siirt province at Southeast Anatolia Region Turkey. Browning on crown root collected saplings drying plants observed. In pathogenicity test, most virulent isolate was Rs2 with a disease severity 93.75%. The group this isol...

background: the main goal of the present study was to set up an axenic cultivation of acanthamoeba and assess the pathogenic ability of t4 genotypes from different clinical and environmental strains of acanthamoeba using two physical assays. methods: sixteen acanthamoeba isolates including 10 environmental and 6 clinical strains were cul-tured axenically. axenic cultivation was performed using ...

Abstract During a survey conducted in June 2019, chlorosis symptoms were observed on lentil leaves field located at Relizane, Algeria. Based morphological and molecular identification, the pathogen was identified as Alternaria chlamydosporigena . A pathogenicity test carried out Koch's postulates verified fulfilled. To our best knowledge, this is first report of A. new worldwide.

Aeromonas infections are becoming a major risk factor in commercial aquaculture and it has been reported that a wide variety of fish and shellfish species are susceptible to this infection. In this study, 3 isolates of Aeromonas hydrophila were isolated from giant freshwater prawn (Macrobrachium rosenbergii) cultured in Kuala Pilah Simbilan Nigri in East Malaysia. Conventional and rapid identif...

H5N2 viruses were isolated from cloacal swab samples of apparently healthy chickens in Taiwan in 2003 and 2008 during surveillance of avian influenza. Each of the viruses was eradicated by stamping out. The official diagnosis report indicated that the Intravenous Pathogenicity Indexes (IVPIs) of the isolates were 0.00 and 0.89, respectively, indicating that these were low pathogenic strains, al...

numerous date palm orchards in south kerman, iran were investigated during 2001-2003. symptoms of leaf die-back appeared as light brown stripes which began at leaf tips and extended to leaf ends. infected tissues were surface sterilized with 0.05% sodium hypochlorite and, plated on pda medium. isolated fungi were purified using hyphal tip method. on pda medium, fungal colony was fluffy, first c...

The pathogenicity of Listeria monocytogenes as influenced by growth on crabmeat at 5 and 10 degrees C was studied. Crabmeat was inoculated with L. monocytogenes V7 (ca. 10(4) CFU/g) and incubated for up to 14 days at 5 and 10 degrees C. At selected incubation times, L. monocytogenes was removed from crabmeat by washing with 0.1 M potassium phosphate buffer (pH 7.0), and populations were determi...

This study was aimed to evaluate and compare the pathogenicity of rabies virus isolated from bats and dogs, and to verify the efficacy of a commercial rabies vaccine against these isolates. For evaluation of pathogenicity, mice were inoculated by the intramuscular route (IM) with 500MICLD₅₀/0.03 mL of the viruses. The cross-protection test was performed by vaccinating groups of mice by the subc...

background: the aims of this study were to identify blastocystis subtypes (sts) in a cohort of turkish patients with various gastrointestinal symptoms using a novel real time pcr method developed recently for blastocystis detection and assess the relationship between blastocystis sts and patient symptoms. methods: totally, 617 stool samples of patients with gastrointestinal symptoms were examin...
