Transcriptomic Analysis Reveals Molecular Mechanisms Underpinning Mycovirus-Mediated Hypervirulence in <i>Beauveria bassiana</i> Infecting <i>Tenebrio molitor</i> by Charalampos Filippou, Robert H. A. Coutts, Ioly Kotta-Loizou, Sam El-Kamand, Alexie Papanicolaou

“…However, beauvericin, a mycotoxin capable of inducing oxidative stress at the molecular level, was expressed in all four isolates, indicating an important contribution to virulence against <i>T. molitor</i>. These observations suggest that detoxification of immune-related (oxidative) defenses and nutrient scouting, as mediated by these genes, occurs in mid-infection during the internal growth phase. …”

Effects of Environmental Temperature on the Dynamics of Ichthyophoniasis in Juvenile Pacific Herring (Clupea pallasii) by Jake L. Gregg, Johanna J. Vollenweider, Courtney A. Grady, Ron A. Heintz, Paul K. Hershberger

“…In addition to defining parameters for a herring bioenergetics model (discussed in Vollenweider et al. this issue), these experiments provided new insights into factors influencing the infectivity and virulence of the parasite Ichthyophonus. In groups of fish with established disease, temperature variation had little effect on disease outcome. …”

Cascading expression of ApiAP2 transcription factors controls daughter cell assembly in Toxoplasma gondii. by Maanasa Bhaskaran, Venkat Mudiyam, Thomas Mouveaux, Emmanuel Roger, Mathieu Gissot

“…While TgAP2III-2 has only a minor impact on the tachyzoite proliferation, we show that TgAP2XII-9 regulates many aspects of the cell cycle including the proper assembly of the daughter cells inner membrane complex and temporal expression of many virulence genes. Creation of a double mutant strain for TgAP2XII-9 and TgAP2III-2 shows that TgAP2XII-9 had a prominent role during daughter cell assembly. …”

“…In this connection, an assumption was made about the evolutionary advantage of the more virulent haplotype III. However, the results of our own research in conjunction with the data of other scientists indicate that the high virulence of individual virus strains is a consequence of the tendency to implement the maximum possible intensity of the synthesis of virus particles but not of the high damaging effect alone. …”
