Scabies is a disease that harms humans and other animals that is caused by the itch mite Sarcoptes scabiei burrowing into the stratum corneum of the skin. In the early stages of scabies, symptoms are often subclinical and there are no effective diagnostic methods. Herein, we cloned, expressed and
The regulatory effect of amino acids on the production of thaxtomin A, a phytotoxin produced by Streptomyces scabies, was investigated. Tryptophan had an important inhibitory effect on the toxin biosynthesis in all five strains of S. scabies tested. Two other aromatic amino acids (tyrosine and
During a survey of potato scab pathogens in China from 2003 to 2012, a new pathogen was found in Shanxi and Neimenggu provinces. The incidence was approximately 20% of all recovered strains. The lesions caused by the pathogen were slightly raised and similar to those caused by Streptomyces scabies
Potato scab disease is caused by gram-positive filamentous bacteria in the genus Streptomyces. A great variety of species cause this disease, but Streptomyces scabies is the most ancient of these pathogens and can be found in a worldwide distribution, whereas S. turgidiscabies and S. acidiscabies
Sarcoptes scabiei (Acari: Sarcoptidae) causes a common contagious skin disease that affects many mammals. Here, the complete mitochondrial genome of a mite, S. scabiei var. nyctereutis, from Japanese wild raccoon dogs was analyzed. The 13,837bp circular genome contained 13 protein-coding genes, two
Streptomyces turgidiscabies Car8 is an actinobacterium that causes the economically important disease potato scab. Pathogenesis in this species is associated with a mobile pathogenicity island (PAISt) that site specifically inserts into the bacA gene in Streptomyces spp. Here we provide the 674,223
Six representative Korean strains of streptomycetes (S33, S27, S71, S63, S77, and S78) that were pathogenic to potato were characterized based on phenotypic properties, analysis of 16S rRNA genes, production of thaxtomin A, and presence of nec1 and ORFtnp gene homologs. Strains S33 and S27 had
PAISt is a large genomic island located in the chromosome of the plant pathogen Streptomyces turgidiscabies Car8. The island carries clustered virulence genes, transfers to other Streptomyces species, and integrates by site-specific recombination at the 8 bp palindrome TTCATGAA. The palindrome is
