Transcriptional Silencing of Multiple Genes in Trophozoites of Entamoeba histolytica
In a previous work we described the transcriptional silencing of the amoebapore A (AP-A) gene (Ehap-a) of Entamoeba histolytica strain HM-1:IMSS. The silencing occurred following transfection with a plasmid containing a 5′ upstream region (473 bp) of Ehap-a that included a truncated segment (140…

The Malarial Host-Targeting Signal Is Conserved in the Irish Potato Famine Pathogen
Animal and plant eukaryotic pathogens, such as the human malaria parasite Plasmodium falciparum and the potato late blight agent Phytophthora infestans, are widely divergent eukaryotic microbes. Yet they both produce secretory virulence and pathogenic proteins that alter host cell functions. In P…

Glanville fritillary butterfly.: Genetic variation at the Pgi locus of the Glanville fritillary butterfly, Melitaea cinxia, has a significant effect on the growth of local populations, and provides direct evidence that the performance of individual genotypes can influence population dynamics. (See…

Stars with SARS.: I began working on this series of images in 2003. They began as an initial response to the striking images I had been seeing in news media and in advertising, both of which often appeared in the same publication. I began collecting images that caught my eye, and then began to turn…

B Cell Antigen Receptor Signaling and Internalization Are Mutually Exclusive Events
Engagement of the B cell antigen receptor initiates two concurrent processes, signaling and receptor internalization. While both are required for normal humoral immune responses, the relationship between these two processes is unknown. Herein, we demonstrate that following receptor ligation, a…

Empirical Support for Optimal Virulence in a Castrating Parasite
The trade-off hypothesis for the evolution of virulence predicts that parasite transmission stage production and host exploitation are balanced such that lifetime transmission success (LTS) is maximised. However, the experimental evidence for this prediction is weak, mainly because LTS, which…

Resistance Evolution to Bt Crops: Predispersal Mating of European Corn Borers
Over the past decade, the high-dose refuge (HDR) strategy, aimed at delaying the evolution of pest resistance to Bacillus thuringiensis (Bt) toxins produced by transgenic crops, became mandatory in the United States and is being discussed for Europe. However, precopulatory dispersal and the mating…

Control of Phage Bxb1 Excision by a Novel Recombination Directionality Factor
Mycobacteriophage Bxb1 integrates its DNA at the attB site of the Mycobacterium smegmatis genome using the viral attP site and a phage-encoded integrase generating the recombinant junctions attL and attR. The Bxb1 integrase is a member of the serine recombinase family of site-specific recombination…

The Obligate Human Pathogen, Neisseria gonorrhoeae, Is Polyploid
We show using several methodologies that the Gram-negative, diplococcal-bacterium Neisseria gonorrhoeae has more than one complete genome copy per cell. Gene dosage measurements demonstrated that only a single replication initiation event per chromosome occurs per round of cell division, and that…
