摘要

在一个375头母猪的猪场厌氧消化系统中，每个月收集一次原液猪粪、厌氧消化出水、筛选过的厌氧消化固体、筛选过的厌氧消化出水、经筛选过的厌氧消化出水离心得到的厌氧消化残渣、离心浓缩液和最终储存的液体出水，为期9个月。猪肠病毒从猪肾细胞培养物中分离出来，最常见的是从生粪肥中分离出来，而从筛选的消化固体、厌氧消化残渣和最终流出的液体中分离出来的频率要低得多。由此得出结论，厌氧消化系统导致显著但不完全的病毒感染性降低。

Virological studies on an anaerobic digestion system for liquid pig manure

Samples of raw liquid pig manure, anaerobic digester effluent, screened digester solids, screened digester effluent, anaerobic digestion residue derived by centrifugation of the screened digester effluent, the centrifuge centrate and the final stored liquid effluent were collected at monthly intervals for 9 months from an anaerobic digestion system operated at a 375-sow pig farm. Porcine enteroviruses were isolated on pig kidney-cell cultures, most frequently from the raw manure, and significantly less frequently from the screened digester solids, anaerobic digestion residue and the final liquid effluent. It was concluded that the anaerobic digestion system resulted in significant, but incomplete, reductions in viral infectivity.
