This work aimed to identify the species distribution of common clinical and environmental isolates of black Aspergilli based on simple restriction fragment length polymorphism (RFLP) analysis of the β-tubulin gene. A total of 149 clinical and environmental strains of black Aspergilli were collected and subjected to preliminary morphological examination. Total genomic DNAs were extracted, and PC...

AIM To analyze the effect of TLR-9 (-1486 T>C) and TLR-9 (C>T) gene polymorphisms both at TLR-9 levels and together with their sepsis parameters. In this regard, the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique was used in order to detect TLR-9 gene polymorphisms, whereas the ELISA technique was used to analyze TLR-9 serum levels in 80 sepsis patients ...

Toxoplasmosis, caused by Toxoplasma gondii, is a parasitic zoonosis with worldwide distribution. The present study investigated the prevalence of T. gondii in dogs in Zhanjiang city, southern China, using both serological and molecular detection. A total of 364 serum samples and 432 liver tissue samples were collected from the slaughter house between December 2012 and January 2013 and were exam...

Soil fungal community structures are often highly heterogeneous even among samples taken from small field plots. Sample pooling is widely used in order to overcome this heterogeneity, however, no objective criteria have yet been defined on how to determine the number of samples to be pooled for representatively profiling a field plot. In the present study PCR/RFLP and T-RFLP analysis of fungal ...

One-hundred eight Mycobacterium avium isolates from pigs, humans, birds, and bovines were typed by the IS1245-based restriction fragment length polymorphism (RFLP) method and PCR-restriction enzyme analysis (PRA) of hsp65. Nine clusters of isolates showing more than 80% similarity in their RFLP profiles were detected. The largest cluster (cluster B) included 32 of 79 pig isolates (40.5%), 3 of ...

ABSTRACT The barley cv. Bolivia carries two leaf rust (Puccinia hordei) resistance genes, Rph2 and Rph6, and is the only known source of the latter gene. A resistant line (Bolivia-Rph6) carrying Rph6 only was obtained in the F(4) generation of a cross between cv. Bolivia and the susceptible cv. Bowman via progeny testing with differential isolates of the leaf rust pathogen. Genetic analyses and...
