All the worms were found dead 72 h post-treatment and showed advanced level of tegumental disruptions, consisting of severe distortion of spines, sloughing off the tegument to expose the basal lamina, formation of pores and isolated patches of lesions.
Avian mortality surveillance for WNV targets fresh carcasses (generally dead <24 h), especially corvids, for detection of infectious virus particles or RNA in brain or other viscera.
As reported for Arabidopsis cell suspensions [ 8], TA induced cell death in poplar suspension cultures; 73% of the cells were dead 48 h after adding 1.0 μM TA.
We compared the percentage of dead sperm 24 h and 96 h after a single mating for SR and ST males using a crossed two-way ANOVA with male genotype and time after the mating as the two factors and we performed t-tests to compare the results between males at each time.
In the control sample (ookinetes incubated with BSA) 6.3% ookinetes were dead by 24 h compared with 5.1% by 2 h.
In the lysozyme c-1 treated sample 3.85% ookinetes were dead by 24 h as compared with 3.80 by 2 h.
All of the mice injected with WT were dead by 12 h post injection, while 5 out of the 10 mice injected with the vvpE mutant remained alive 24 h after i.p. inoculation, thus showing some degree of the attenuation of mouse lethality.
These changes were exaggerated and several cells were found dead after 48 72 h.
The cell lines were cultured from integument biopsies of free-ranging and stranded cetaceans (dead within 12 h).
In primary cultures of kidney cells derived from the Terminator mouse, over 99.99% of cells were dead within 72 h of diphtheria toxin treatment.
Up to a concentration of 0.025 g/L all Daphnia were still alive after 24 hours, and above 0.075 g/L all were dead within 13 h (Fig. 1).
