Acquired macrolide resistance genes in Haemophilus influenzae?
OBJECTIVES The objective of this study was to determine the prevalence of specific acquired macrolide resistance genes previously reported as present in clinical isolates of Haemophilus influenzae. METHODS A collection of 172 clinical respiratory isolates of H. influenzae, including 59 isolates from cystic fibrosis patients and 27 from non-cystic fibrosis bronchiectasis patients with signific...
متن کاملAcanthopanax sessiliflorus stem confers increased resistance to environmental stresses and lifespan extension in Caenorhabditis elegans
BACKGROUND/OBJECTIVES Acanthopanax sessiliflorus is a native Korean plant and used as traditional medicine or an ingredient in many Korean foods. The free radical theory of aging suggests that cellular oxidative stress caused by free radicals is the main cause of aging. Free radicals can be removed by cellular anti-oxidants. MATERIALS/METHODS Here, we examined the anti-oxidant activity of Aca...
متن کاملHaemophilus parasuis diagnostics
In the past few years, our understanding of the dynamics of Haemophilus parasuis infection has greatly improved. Techniques such as polymerase chain reaction (PCR) for detection of this microorganism in clinical samples and genotyping of field isolates have certainly enhanced our knowledge on prevalence and epidemiology of infection. Although we still have a long way to go regarding the develop...
متن کاملTwo Glycosyltransferase Genes of Haemophilus parasuis SC096 Implicated in Lipooligosaccharide Biosynthesis, Serum Resistance, Adherence, and Invasion
Haemophilus parasuis is a common opportunistic pathogen known for its ability to colonize healthy piglets and causes Glässer's disease. The lipooligosaccharide (LOS) of H. parasuis is a potential virulence-associated factor. In this study, two putative glycosyltransferases that might be involved in LOS synthesis in H. parasuis SC096 were identified (lgtB and lex-1). Mutants were constructed to ...
متن کاملPlasmid-encoded Tet B tetracycline resistance in Haemophilus parasuis.
The complete sequence of two plasmids, pHS-Tet (5.1 kb) and pHS-Rec (9.5 kb), isolated from Haemophilus parasuis strain HS1543 has been obtained. Plasmid pHS-Tet contains four open reading frames including a tet(B) tetracycline resistance gene which unusually did not have an associated tetR repressor gene. From a total of 45 H. parasuis isolates surveyed (15 international reference strains, 15 ...
