Introduction Glanders is one of the oldest contagious and dangerous zoonotic diseases manifesting ulcerative granulomatous lesions on the skin and mucous membranes. Early methods possessing desirable sensitivity and specificity is important to diagnose the disease considering the just only one case report and preventing disease by identification and eradication. The present study was aimed to ...
Viable microbes have been detected beneath several geographically distant glaciers underlain by different lithologies, but comparisons of their microbial communities have not previously been made. This study compared the microbial community compositions of samples from two glaciers overlying differing bedrock. Bulk meltwater chemistry indicates that sulfide oxidation and carbonate dissolution a...
ELISA, cDNA dot blot hybridization and transmission by vector aphids were used to investigate the occurrence and degree of cross-protection produced in oat plants by virus isolates representing five strains or serotypes of barley yellow dwarf virus, namely PAV, MAV, SGV, RPV and RMV. Generally, the degree of cross-protection was positively correlated with the serological relatedness between the...
BACKGROUND Bacteria and yeasts isolated from respiratory tracts of 39 Cambodian and 28 Kenyan HIV-positive children were tested for the presence of HIV-1 sequences. MATERIAL/METHODS Bacteria and yeasts from the respiratory tract (nose, pharyngeal swabs) were isolated from 39 Cambodian and 28 Kenyan HIV-positive children. Bacterial chromosomal DNA was prepared by standard protocol and by Qiage...
Campylobacter jejuni colonization of chickens is presumably dependent upon multiple surface-exposed proteins termed adhesins. Putative C. jejuni adhesins include CadF, CapA, JlpA, major outer membrane protein, PEB1, Cj1279c, and Cj1349c. We examined the genetic relatedness of 97 C. jejuni isolates recovered from human, poultry, bovine, porcine, ovine, and canine sources by multilocus sequence t...
This paper deals briefly with a technique developed for the identification of the early stages of veligers of the surfclam Spisula solidissima from the larval stages of other common bivalve species using a combination of DNA probe and restriction fragment length polymorphism (RFLP) analysis. An oli¬ gonucleotide sequence designed from the 18S ribosomal RNA gene (nucleotide position 259-276) pro...
Brief micrococcal nuclease digestion of chick embryonic red blood cells results in preferential excision and solubilization of monomer nucleosomes associated with beta-globin sequences and also 5'-sequences flanking the beta-globin gene. Both regions are DNAse-I sensitive in nuclei. Such salt-soluble nucleosomes are enriched in all four major HMG proteins but HMG1 and 2 are only weakly associat...
A method incorporating DNA amplification and reverse dot blot hybridization for the detection and identification of mycobacteria to the species level is described. The amplification procedure allowed for the incorporation of digoxigenin-labeled UTP, which was detected by chemiluminescence, removing the need for radioactivity. Using a set of primers and probes from the gene for the 65-kDa heat s...
objective: the lrr (leucine rich proteoglycans) is a molecular recognition motif found in proteins with some roles in cell adhesion, signal transduction, dna repair and rna processing. opticin is a member of this family. takanosu et al (2001) detected messenger rna expression of mouse opticin in the eye, heart, brain, testis, thyroid and epididymis by dot blot hybridization. in this study, exp...
