The induction of lytic replication of the Epstein-Barr virus (EBV) completely arrests cell cycle progression, in spite of elevation of S-phase cyclin-dependent kinase (CDK) activity, thereby causing accumulation of hyperphosphorylated forms of retinoblastoma (Rb) protein (A. Kudoh, M. Fujita, T. Kiyono, K. Kuzushima, Y. Sugaya, S. Izuta, Y. Nishiyama, and T. Tsurumi, J. Virol. 77:851-861, 2003)...

The postpartum involution of corpora lutea was examined by electron microscope cytochemistry of guinea pig ovaries previously fixed by vascular perfusion, a method which produces optimal preservation of steroid-secreting cells and yet maintains enzyme activity. The intracellular digestive apparatus was identified through the localization of two acid hydrolases, acid phosphatase (ACPase) and ary...

Like all other herpesviruses, the oncogenic human gammaherpesvirus, Epstein-Barr virus (EBV; human herpesvirus 4) manifests two distinct phases in its life cycle: latency and lytic replication. During latency EBV expresses a limited number of viral genes that are involved in tasks such as stimulating cell proliferation, inhibiting apoptosis, blocking viral lytic replication, and assuring accura...

The oomycete pathogen Aphanomyces astaci, also known as “crayfish plague”, is an obligate fungal-like parasite of freshwater crustaceans and considered responsible for the ongoing decline native European crayfish populations. A. astaci thought to secrete a wide array effectors enzymes that facilitate infection, however their molecular mechanisms have been poorly characterized. Here, we report i...

Staphylococcal biofilms are a major concern in both clinical and food settings because they are an important source of contamination. The efficacy of established cleaning procedures is often hindered due to the ability of some antimicrobial compounds to induce biofilm formation, and to the presence of persister cells, a small bacterial subpopulation that exhibits multidrug tolerance. Phage lyti...
