Group B Streptococcus (GBS), a commensal in the body, causes wide range of infectious diseases. This bacterium is dangerous for pregnant women and their babies, whom it responsible early neonatal bacterial sepsis (EOS). The colonisation levels GBS its resistance profile to antibiotics provide important information that useful orienting prevention strategies. There are few data available on subj...

In 540 beta-hemolytic streptococci, the rates of resistance to tetracycline, chloramphenicol, erythromycin, and clindamycin were 80.0, 22.8, 20.2, and 19.1%, respectively. Of the erythromycin-resistant isolates, 63.3% had the constitutive macrolide-lincosamide-streptogramin B (MLSB) resistance phenotype, 23.9% had the M phenotype, and 12.8% had the inducible MLSB resistance phenotype. The const...

Pseudomonas aeruginosa PAO lacks UV-inducible Weigle reactivation and Weigle mutagenesis of UV-damaged bacteriophages. This lack of UV-inducible, error-prone DNA repair appears to be due to the absence of efficiently expressed umuDC-like genes in this species. When the P. aeruginosa recA gene is introduced into a recA(Def) mutant of Escherichia coli K12, the P. aeruginosa recA gene product is c...

Vasculogenic mimicry (VM) is the release of angiogenic factors from tumor cells, leading to morphological changes, migration and proliferation vascular endothelial ultimately neovascularization. The presence VM has been identified in breast cancer, formation also gives cancer a poor prognosis such as drug resistance metastasis. authors focus on role PI3K/Akt signaling pathway, hypoxia-inducible...
