Streptococcus suis and Streptococcus equi subsp. zooepidemicus are capable of infecting humans and various animals, causing significant problems for the worldwide swine industry. As antibiotic resistance has increased, lysosomal enzymes encoded by phages have shown potential for use against pathogenic bacteria. In this study, a novel bacteriophage lysin, Ply30, encoded by the S. suis prophage p...
This study was aimed at determining the prevalence and characterising the strains of Salmonella species in various captive reptiles in the Czech Republic. A total of 211 samples of cloacal swabs from lizards, chelonians and snakes, and 14 swabs from terraria surfaces were collected between November 2014 and July 2015. After isolation according to the reference method (EN ISO), Salmonella spp. i...
Plasmid transfer between Bacillus thuringiensis subsp. kurstaki HD1 and B. thuringiensis subsp. tenebrionis donor strains and a streptomycin-resistant B. thuringiensis subsp. kurstaki recipient was studied under environmentally relevant laboratory conditions in vitro, in soil, and in insects. Plasmid transfer was detected in vitro at temperatures of 5 to 37 degrees C, at pH 5.9 to 9.0, and at w...
The pulsed-field gel electrophoresis (PFGE) pattern of SmaI digests of 29 strains of Lactococcus lactis subsp. lactis and subsp. cremoris were determined. Unrelated strains yielded markedly different patterns of digestion products. Bacteriophage-resistant derivatives of four strains, generated by a method analogous to that used regularly in some cheese factories, yielded patterns that were iden...
جنس zoegea l. با نام فارسی خورشید صبح از تیره کاسنی دارای حدود 1 گونه و 5 زیرگونه در دنیاست که یک عنصر ایرانو تورانی و مدیترانهای محسوب میشود. این جنس در ایران - دارای 6 تاکسون است که متعلق به 9 گونه میباشند: z. crinita subsp. crinita ، z. crinita subsp. glabricaulis ، z. crinita subsp. baldschuanica ، z. leptaurea s ، ubsp. mianensis z. leptaurea subsp. mesopotamica و zoegea purpurea . در مو...
A sandwich immunoassay for the rapid, low-level detection of Mycobacterium avium subsp. paratuberculosis has been developed. M. avium subsp. paratuberculosis is the causative agent of Johne's disease in cattle, and one of the major obstacles in controlling the spread of this disease is the inability to rapidly detect small amounts of bacteria or other diagnostic markers shed during the subclini...
RNA was degraded at 60 degrees C for 24 h by halophilic nuclease H in supernatants from broth cultures of Micrococcus varians subsp. halophilus containing 12% NaCl. Since contaminating 5'-nucleotidase exhibited almost no activity under these conditions, the 5'-GMP formed could be recovered from the reaction mixture, and the yield was 805 mg from 5 g of RNA.
تحقیق حاضر بهمنظور بررسی سمیت غلظتهای مختلف (صفر، 50، 100، 200 و 400 میکروگرم بر میلی‌لیتر) نانواکسید آهن (Fe3O4) بر جوانهزنی، رشد ریشهچه، ساقهچه و گیاهچه دو گونه Fisch. ex Link Agropyron desertorumو Agropyron elongatum (Host). Beauv بر پایه طرح کاملا تصادفی با 4 تکرار صورت گرفت. نتایج نشان داد، غلظت بالای نانواکسید آهن کاهش درصد جوانهزنی و رشد گیاهچه در دو گونه مورد مطالعه را به دنبال...
Teosinte ( subsp. H. H. Iltis & Doebley) has greater genetic diversity than maize inbreds and landraces ( subsp. ). There are, however, limited genetic resources to efficiently evaluate and tap this diversity. To broaden resources for genetic diversity studies in maize, we developed and evaluated 928 near-isogenic introgression lines (NILs) from 10 teosinte accessions in the B73 background. Joi...
An outbreak of fatal hemorrhagic pneumonia with 70-90% morbidity and 50% mortality occurred in an animal shelter in Yangju, Gyeonggi Province, Korea. Clinically, the affected dogs showed severe respiratory distress within 48 h after arriving in the shelter. The dead were found mainly with nasal bleeding and hematemesis. At necropsy, hemothorax and hemorrhagic pneumonia along with severe pulmona...
