Bit swapping linear feedback shift register (BS-LFSR) is employed in a conventional linear feedback shirt register (LFSR) to reduce its power dissipation and enhance its performance. In this paper, an enhanced BS-LFSR for low power application is proposed. To achieve low power dissipation, the proposed BS-LFSR introduced the stacking technique to reduce leakage current. In addition, three diffe...

the sip gene encoding for a conserved highly immunogenic surface protein of streptococcus agalactiae was amplified using polymerase chain reaction (pcr) and subcloned into prokaryotic expression vector pet32a (+) and expressed as a recombinant protein in e. coli bl21 (de3). an indirect enzyme linked immunosorbent assay (elisa) was developed using the purified sip protein as a coating antigen, w...

Chylothorax is bacteriostatic in nature. Bacterial infection rarely develops in chylothorax and has never been reported in a non-immunocompromised host. A 33-year-old woman was admitted to National Taiwan University Hospital because of fever and right pleuritic pain. Chest roentgenography and computed tomography revealed right pleural effusion. Examination of the pleural effusion revealed a pro...

We present a case of infective endocarditis associated with community-acquired Streptococcus agalactiae in an immune competent patient. The endocarditis affected the native aortic valve with perforation of the coronary cusp and was complicated by a cerebral embolism. The use of intravenous ampicillin produced a satisfactory clinical and echocardiographic recovery despite not receiving a valve r...

background: group b streptococcus (gbs) colonizes the gastrointestinal and genitourinary tract of 10-40% of pregnant women and it is a major cause of neonatal morbidity and mortality. objective: this study was to evaluate whether vaginal gbs culture results alter after digital vaginal examination or not. antibiotic resistance pattern of this specie has been also assessed. materials and methods:...

The activity of tigecycline was tested against erythromycin-resistant streptococci (107 Streptococcus pyogenes and 98 Streptococcus agalactiae strains). The presence of erythromycin and tetracycline resistance genes was determined by PCR. Among S. pyogenes strains the most prevalent gene was mef(A) (91.6%). The erm(B) gene was the most prevalent (65.3%) among S. agalactiae strains. Tigecycline ...

Whole-cell protein electrophoretic analysis of the type strain of Streptococcus difficile (LMG 15799) revealed that this organism was indistinguishable from Streptococcus agalactiae strains. Although LMG 15799T (T = type strain) was originally described as serologically untypeable, we found that this strain was a group B streptococcus belonging to the capsular polysaccharide antigen type Ib gro...

Streptococcus agalactiae is an important microorganism involved in a number of conditions in pregnant women, newborns, elderly people (over 65 years of age) and individuals with chronic disabling illnesses. This pathogen is infrequently found among patients outside this age range or clinical profile(1-5) and is rarely reported in the etiology of sexually transmitted diseases. Here we describe a...

The brownseed mutants (bs(1), bs(2), and bs(4)) of tomato all possess dark testae and deleteriously affect seed germination speed and/or final percentage. Poor germination performance of the bs(1) but not the bs(4) mutant, was due to greater impediment to radicle egress. Testa toughening (bs(1)) was prevented by drying in N(2). However, poor germination speed was hardly affected by drying. GA(4...
