Objective: Considering the emergence of biofilm-associated pathogens with multidrug resistance, the objective(s) of the present study was to evaluate the anti-virulence property of Syzygium aromaticum extracts/fractions against 2 multidrug-resistant catheter isolates. Materials and Methods: Pulverized clove buds were subjected to bioactivity-guided isolation to identify the bioactive extract/fr...

The sheath rot rice disease is known to be associated Pseudomonas fuscovaginae and a recent study on the symptomatic of revealed that this bacterial pathogen abundant in highland ecology cultivation Burundi. From asymptomatic samples rice, collection isolates culturable microbiome have been carried out. A comparison between total was made. Phenotypic assays vitro were performed after identifica...

The incidence of Lactococcosis caused by Lactococcus garvieae, in rainbow trout (Oncorhynchus mykiss, Walbaum, 1792) farms is disquieting and increasing in recent years. Knowledge of biotypes and serotypes involved in disease incidence is essential to adopt disease prevention and control policies. Twelve isolates of L. garvieae from some rainbow trout farms were identified by phenotypic, bioche...

Label-free biosensors offer integrated, kinetic and multi-parametric measures of receptor biology and ligand pharmacology in whole cells. Being highly sensitive and pathway-unbiased, label-free receptor assays can be used to probe the systems cell biology including pleiotropic signaling of receptors, and to characterize the functional selectivity and phenotypic pharmacology of ligand molecules....

OBJECTIVES Multidrug-resistant tuberculosis has emerged as a global health threat. Given poor treatment outcomes of fluoroquinolone-resistant multidrug-resistant tuberculosis, there is a pressing need for rapid drug susceptibility testing of multidrug-resistant Mycobacterium tuberculosis against fluoroquinolones. This review aims at evaluating these rapid assays. METHODS PubMed and OvidSP wer...

BACKGROUND Human Immunodeficiency virus type-1 (HIV) entry into target cells involves binding of the viral envelope (Env) to CD4 and a coreceptor, mainly CCR5 or CXCR4. The only currently licensed HIV entry inhibitor, maraviroc, targets CCR5, and the presence of CXCX4-using strains must be excluded prior to treatment. Co-receptor usage can be assessed by phenotypic assays or through genotypic p...

OBJECTIVE A novel rapid reverse transcriptase (RT) recombinant HIV-1 drug-susceptibility assay was developed to evaluate resistance to RT inhibitors. MATERIAL AND METHODS HIV-1 RTs from five treatment-naive and 10 highly active antiretroviral therapy-experienced patients were evaluated. HIV-1 isolates recovered by culturing peripheral blood mononuclear cells from patients were used in the con...
