The environment is heavily populated with polycyclic aromatic hydrocarbons (PAHs), which are dangerous to human health. Degradation and cleaning of PAH chemicals from water soil regions crucial due their chemical biological impacts persistent nature. In this study, we found that a very efficient bacterial consortium A-LOBP-19A+LOP-9 (99.62%) for benzo[a]pyrene up 1000ppm B-LOP-9 +GWP-2 (93.8%) ...
BACKGROUND It is essential to investigate the serotype distribution of pneumococcal diseases in each region and its associated clinical features. This study investigated the annual incidence of invasive pneumococcal disease (IPD) and the distribution of serotypes of isolates causing IPD at a medical center in northern Taiwan during the period 2000 to 2012. METHODS Serotypes of all available S...
Chemokines mediate monocyte adhesion to dysfunctional endothelial cells (ECs) and promote arterial inflammation during atherosclerosis. Hypoxia-inducible factor (HIF)-1α is expressed in various cell types of atherosclerotic lesions and is associated with lesional inflammation. However, the impact of endothelial HIF-1α in atherosclerosis is unclear. HIF-1α was detectable in the nucleus of ECs co...
Streptococcus pneumoniae is an important cause of otitis media and invasive disease. Since introduction of the heptavalent pneumococcal conjugate vaccine, there has been an increase in replacement disease due to serotype 19A clonal complex (CC)199 isolates. The goals of this study were to 1) describe genetic diversity among nineteen CC199 isolates from carriage, middle ear, blood, and cerebrosp...
The multidrug-resistant Streptococcus pneumoniae Taiwan(19F)-14, or PMEN14, clone was first observed with a 19F serotype, which is targeted by the heptavalent polysaccharide conjugate vaccine (PCV7). However, "vaccine escape" PMEN14 isolates with a 19A serotype became an increasingly important cause of disease post-PCV7. Whole genome sequencing was used to characterize the recent evolution of 1...
The heptavalent pneumococcal conjugate vaccine (PCV7) was introduced in the United States (US) in 2000 and has significantly reduced invasive pneumococcal disease; however, the incidence of nonvaccine serotype invasive disease, particularly due to serotype 19A, has increased. The serotype 19A increase can be explained in part by expansion of a genotype that has been circulating in the US prior ...
We used mouse models of pneumococcal colonization and disease combined with full genome sequencing to characterize three major drug resistant clones of S. pneumoniae that were recovered from the nasopharynx of PCV7-immunized children in Portugal. The three clones--serotype 6A (ST2191), serotype 15A (ST63) and serotype 19A (ST276) carried some of the same drug resistance determinants already ide...
OBJECTIVES The aim of this study was to evaluate susceptibility to common paediatric antibiotics for Streptococcus pneumoniae, non-typeable Haemophilus influenzae and Moraxella catarrhalis isolated from 2005 through 2007. METHODS Microdilution MIC assays were performed using CLSI-approved methods. S. pneumoniae 19A strains were identified by quellung reaction. RESULTS Among 143 non-typeable...
BACKGROUND Streptococcus pneumoniae is a common cause of otitis media (OM) in children; mastoiditis remains an important complication of OM. Limited data are available on the impact of the 13-valent pneumococcal conjugate vaccine (PCV13) on pneumococcal otitis. METHODS Investigators from 8 children's hospitals in the United States prospectively collected pneumococcal isolates from middle ear ...
