The effect of porcine circovirus type 2 on classical swine fever virus-induced proliferation of porcine peripheral blood mononuclear cells
|
Abstract
Porcine circovirus type 2 (PCV2) is infectious to post-weaning pigs between 25 and 120 days old and proves to down-regulate the immune response of swine. The PCV2-susceptible age of pigs is known to overlap with the vaccination programs of the LPC vaccines at 3- and 6-week of age or 6- and 9-week of age. In the present study, the effect of PCV2 on cell mediated immunity (CMI) was evaluated by classical swine fever virus (CSFV)-induced proliferation of peripheral blood mononuclear cells (PBMC). We found that in vitro CSFV-induced proliferation of PBMC could be induced with the stimulation of 0.1 MOI of ALD strain for at least 4 days. Moreover, the effect of PCV2 on CSFV-induced proliferation of PBMC was examined and found that PCV2 was able to significantly reduce the viability, CD25 expression, and CSFV-induced proliferation of PBMC (P < 0.05). These results also indicate that PCV2 was able to suppress the CSFV-induced proliferation of PBMC and could subsequently affect the ability of CMI against CSFV.

Seroprevalence of cattle and goat melioidosis in Taiwan
|
Abstract
To investigate the seroprevalence of goat and cattle antibodies against Burkhoderia pseudomallei, both an enzyme-linked immunosorbent assay (ELISA) and a complement fixation test (CFT) were conducted. In this study, goat sera collected from various areas of Taiwan in different time, including 300 goat sera collected in 2008 from 4 counties located in southern and middle-western Taiwan, 650 goat sera collected in 2007 from 4 counties located in southern and southeastern Taiwan, and 634 cattle sera collected in 2007 from 4 counties located in southern and southeastern Taiwan, were tested. All tested sera, except 2 goat sera collected in 2007, showed negative by both ELISA and CFT. The 2 positive goat sera had CFT titer of 1:20 and 1:10, respectively. The overall seroprevalence of melioidosis for cattle and goats were 0 and 0.21 %.
