As observed in the present study, the oral administration of bac-vp28 to shrimp generated a higher survival rate compared with immersion or other forms of vaccination in addition, the good biosafety profile of the baculovirus as a vaccine vector in both humans and shrimp make it an attractive choice. After iv administration of 150 mg 3h-ranitidine, 98% of the dose was recovered, including 5% in faeces and 93% in urine, of which 70% was unchanged parent drug after oral administration of 150 mg 3h-ranitidine, 96% of the dose was recovered, 26% in faeces and 70% in urine of which 35% was unchanged parent drug. The protection against wssv disease after oral administration of the purified recombinant vp28 was assessed by calculating the relative percent survival the time–mortality relationships in the first experiment are shown in fig 2 .
