Monepantel is a member of the recently identified class of anthelmintics known as the amino-acetonitrile derivatives ( AADs ) . Monepantel controls all major gastro-intestinal nematodes in sheep including those that are resistant to the classical anthelmintics . Previous studies have shown that the Caenorhabditis elega...

Familial clustering and ethnic differences suggest that visceral leishmaniasis caused by Leishmania donovani is under genetic control . A recent genome scan provided evidence for a major susceptibility gene on Chromosome 22q12 in the Aringa ethnic group in Sudan . We now report a genome-wide scan using 69 families with...
The parasitic disease kala-azar , or visceral leishmaniasis , is associated with liver , spleen , and lymph gland enlargement , as well as fever , weight loss , and anaemia . It is fatal unless treated . Three major foci of disease occur in India , Sudan , and Brazil . Importantly , 80%–90% of infections are asymptomat...

In higher eukaryotes , induced resistance associates with acquisition of a priming state of the cells for a more effective activation of innate immunity; however , the nature of the components for mounting this type of immunological memory is not well known . We identified an extracellular subtilase from Arabidopsis , ...
Following a first encounter with a pathogen , higher eukaryotes develop enhanced resistance to subsequent infections by a broad spectrum of pathogens . This type of induced resistance ( IR ) exhibits memory characteristics after the first encounter with a pathogen —training effect— and appears evolutionarily conserved ...

Hsp70 is a well-conserved molecular chaperone involved in the folding , stabilization , and eventual degradation of many “client” proteins . Hsp70 is regulated by a suite of co-chaperone molecules that assist in Hsp70-client interaction and stimulate the intrinsic ATPase activity of Hsp70 . While previous studies have ...

Our aim was to broaden the utility of this scheme to incorporate a total of seven pathogenic species . We modified the existing scheme by replacing one of the seven MLST loc...
Leptospirosis is a common zoonotic disease worldwide . Genotyping of the causative organisms provides important insights into disease transmission and informs preventive strategies and vaccine development . Multilocus sequence typing ( MLST ) is the most widespread genotyping methodology for bacterial pathogens , but t...

A Single Multilocus Sequence Typing (MLST) Scheme for Seven Pathogenic Leptospira Species
The Vpu accessory protein promotes HIV-1 release by counteracting Tetherin/BST-2 , an interferon-regulated restriction factor , which retains virions at the cell-surface . Recent reports proposed β-TrCP-dependent proteasomal and/or endo-lysosomal degradation of Tetherin as potential mechanisms by which Vpu could down-r...
Restriction factors are cellular proteins that interfere with the multiplication and transmission of viruses and are therefore important components of natural immunity . Tetherin ( also known as BST-2 ) is a recently identified restriction factor that traps viruses at the cell-surface , preventing their release and thu...
