Biosynthesized silver nanoparticles: are they effective antimicrobials?

Mem. Inst. Oswaldo Cruz; 112 (8), 2017
BACKGROUND Silver nanoparticles (AgNPs) are increasingly being used in medical applications. Therefore, cost effective and green methods for generating AgNPs are required. OBJECTIVES This study aimed towards the biosynthesis, characterisation, and determination of antimicrobial activity of AgNPs produ...

Protection mediated by chemokine CXCL10 in BALB/c mice infected by Leishmania infantum

Mem. Inst. Oswaldo Cruz; 112 (8), 2017
BACKGROUND Visceral leishmaniasis (VL) caused by Leishmania infantum is characterised by the loss of the ability of the host to generate an effective immune response. Chemokines have a direct involvement in the pathogenesis of leishmaniasis, causing a rapid change in the expression of these molecules du...

¿Se debe revisar la determinación de la CIM de colistín en Acinetobacter baumannii?

Rev. chil. infectol; 34 (4), 2017
Currently, there is a controversy in how to determine the minimal inhibitory concentration (MIC) of colistin against Acinetobacter baumannii. We compared three methods, concluding that the addition of Tween-80 (0.002%) to Müller-Hinton broth in the microdilution method could improve MIC determination an...

Interacciones evolutivas como un posible mecanismo de interacción medicamentosa: una aproximación para el control de la resistencia bacteriana

Rev. chil. infectol; 34 (4), 2017
Resumen En el siglo XXI, la humanidad se encuentra frente a una era post-antibiótica, en la cual es común la aparición de infecciones con una menor o nula alternativa terapéutica. En este contexto, se hace indispensable implementar medidas que optimicen el arsenal terapéutico disponible, generando n...

Desarrollo de un modelo experimental de osteonecrosis de maxilar asociada al tratamiento crónico con aminobisfosfonatos
Experimental model of osteonecrosis of the jaw associated to chronic treatment with aminobisphosphonates

Actual. osteol; 13 (2), 2017
La osteonecrosis de maxilar asociada a aminobisfosfonatos (BRONJ) constituye un efecto secundario del tratamiento crónico con los más potentes. Un modelo experimental permitiría determinar la patogenia de dicha alteración. La oveja presenta características orales y del metabolismo óseo similar al h...

In vitro susceptibility of nematophagous fungi to antiparasitic drugs: interactions and implications for biological control

Braz. j. biol; 77 (3), 2017
Abstract The fast anthelmintic resistance development has shown a limited efficiency in the control of animal's endoparasitosis and has promoted research using alternative control methods. The use of chemicals in animal anthelmintic treatment, in association with nematophagous fungi used for biological c...
