Screening for efflux pump systems of bacteria by the new acridine orange agar method.

  • Authors: Amaral L, Martins A
  • Journal: In vivo
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/?term=Screening+for+efflux+pump+systems+of+bacteria+by+the+new+acridine+orange+agar+method

AIM:
Development of a non-toxic, fluorescent-based, agar system for the screening of overexpressed bacterial efflux pump systems with common, inexpensive UV accessories.

The activity of 16 new hydantoin compounds on the intrinsic and overexpressed efflux pump system of Staphylococcus aureus.

  • Authors: Amaral L, Armada A, Dymek A, Handzlik J, Kiec-Kononowicz K, Molnar J, Spengler G, Viveiros M
  • Journal: In vivo
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/?term=The+Activity+of+16+New+Hydantoin+Compounds+on+the+Intrinsic+and+Overexpressed+Efflux+Pump+System+of+Staphylococcus+aureus

AIM:
To evaluate a new series of 16 hydantoin derivatives for activity against the intrinsic and overexpressed efflux pumps of the ATTC 25923 Staphylococcus aureus and the clinical Staphylococcus aureus HPV-107 strain, respectively.

Potential therapy of multidrug-resistant and extremely drug-resistant tuberculosis with thioridazine.

  • Authors: Amaral L, Molnar J
  • Journal: In vivo
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/22351663

Multidrug-resistant tuberculosis (MDRTB) infections that continue to increase in frequency globally have progressed to become extremely drug-resistant tuberculosis (XDRTB). The therapeutic problems associated with MDRTB pale in comparison to those for XDRTB where mortality is high.

Contribution of efflux activity to isoniazid resistance in the Mycobacterium tuberculosis complex.

  • Authors: Amaral L, Couto I, Machado D, Rodrigues L, Viveiros M
  • Journal: Infection Genetics and Evolution
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/?term=Contribution+of+efflux+activity+to+isoniazid+resistance+in+the+Mycobacterium+tuberculosis+complex.+Infection

Resistance to isoniazid (INH), one of the main drugs used in tuberculosis (TB) therapy, is mostly due to chromosomal mutations in target genes. However, approximately 20-30% of INH resistant Mycobacterium tuberculosis isolates do not have mutations in any of the genes associated with INH resistance.

Inhibitors of mycobacterial efflux pumps as potential boosters for anti-tubercular drugs.

  • Authors: Ainsa J, Amaral L, Couto I, Machado D, Martins M, Rodrigues L, Viveiros M
  • Journal: Expert Review of Anti-infective Therapy
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/?term=Inhibitors+of+mycobacterial+efflux+pumps+as+potential+boosters+for+anti-tubercular+drugs

Tuberculosis is one of the major causes of infection across the world. The emergence of multi-, extensively- and totally drug-resistant strains of Mycobacterium tuberculosis contributes to the lack of therapeutic options available.
