The production of virulence determinants and biofilm formation in numerous pathogens is regulated by the cell-density-dependent phenomenon, Quorum sensing (QS). The QS system in multidrug resistant opportunistic pathogen, P. aeruginosa constitutes of three main regulatory circuits namely Las, Rhl, and Pqs which are closely linked to its pathogenicity and establishment of chronic infections. In spite intensive antibiotic therapy, P. aeruginosa continue to be an important cause of nosocomial infections and also the major cause of mortality in Cystic Fibrosis patients with 80% of the adults suffering from chronic P...

Small viral proteins with cationic domains can be involved in multiple biological processes including cell penetration or interaction with intracellular targets. Within the last two decades several reports indicated that the C-terminus of HIV-1 Vpr is a cell penetrating sequence, a PP2A-dependent death domain and also displays toxicity against Gram-negative E. coli. Interestingly, HIV-1 Vpr, as well as some cationic proteins encoded by different viruses, share similar physical properties with the unique anti-microbial human cathelicidin LL37 peptide...

Cranioplasty (CP) is considered a low-risk operation in the field of neurosurgery following decompression craniectomy. Nevertheless, CP is still burdened by surgical complications, among which early or late infections are the most common outcome-threatening ones. Most of infection cases occur within a week after CP. Except that, implant-associated scalp infection is the most common complication, and leads to implant removal in many patients with refractory and recurrent infection. The authors reported a patient presenting with epidural infection about 3 months after titanium implant and cured by anti-infective treatment for 2 weeks...

The WalK/WalR two-component system (TCS), originally identified in Bacillus subtilis, is very highly conserved in gram-positive bacteria, including several important pathogens. The WalK/WalR TCS appears to be involved in the growth of most bacterial species encoding it. Previous studies have indicated conserved functions of this system, defining this signal transduction pathway as a crucial regulatory system for cell wall metabolism. Because of such effects on essential functions, this system is considered a potential target for anti-infective therapeutics...

This paper reports the diagnosis and treatment of 2 cases of acute schistosomiasis with ectopic lesion in the lung. It suggests that in schistosomiasis endemic areas, if the patients with the contact history of infested water have the symptom of fever, while the effects of anti-infection and the corresponding treatments are not good, the clinician should consider acute schistosomiasis.

Sortase A (SrtA)-catalyzed anchorage of surface proteins in most Gram-positive bacteria is indispensable for their virulence, suggesting that this transpeptidase is a promising target for antivirulence therapy. Here, an oligopeptide, LPRDA, was identified as an effective inhibitor of SrtA via virtual screening based on the LPXTG substrate sequence, and it was found to inhibit SrtA activity in vitro and in vivo (IC50 = 10.61 μM) by competitively occupying the active site of SrtA. Further, the oligopeptide treatment had no anti- Staphylococcus aureus activity, but it provided protection against S...
