Abstract
AIMS Our study aimed to evaluate the effects of different dosages of sodium butyrate and niacin on the growth performance, fecal vitamin B and microbiota in weaned piglets. METHODS AND RESULTS Seventy-two weaned piglets (Duroc×Landrace×Yorkshire, age of 21d) were randomly assigned to 1 of 6 treatments (12 pigs / treatment): the control (CT) group was administered a basal diet. The groups which concentration ratio of sodium butyrate to niacin were 100: 1, 100: 2, 100: 4, 100: 8 and 100: 16 (BN1, BN2, BN4, BN8, BN16) were administered a basal diet supplemented with 2000 mg·kg-1 sodium butyrate and 20 mg·kg-1 , 40 mg·kg-1 , 80 mg·kg-1 , 160 mg·kg-1 or 320 mg·kg-1 niacin. After 14-d treatment, the samples were collected. The results showed that feed conversion rate (FCR) was reduced and average daily gain (ADG) was increased in BN2 (P < 0.05). The diarrhea index of pigs decreased with the low supplement. Additionally, compared with CT group, other groups significantly increased (P < 0.05) the abundance of Firmicutes (BN4, phylum), Lactobacillaceae (BN8, family), Megasphaera (BN8, genus), and Lactobacillus (BN8, genus). Furthermore, the sodium butyrate and niacin supplementation influence vitamin B1, vitamin B2, pyridoxine, niacin, nicotinamide, and vitamin B12 (P < 0.05). Correlation analysis of the association of microorganisms with vitamin B indicated that changes of vitamin B metabolism have potential correlation with alterations of fecal microbiota in weaned piglets. CONCLUSIONS The results indicated that adding of sodium butyrate and niacin in the diet could promote the performance and improve the fecal microbiota and vitamin B metabolism in weaned piglets. SIGNIFICANCE AND IMPACT OF THE STUDY Our study might provide clues to the research of correlations between fecal bacteria and fecal vitamin B, and these findings will contribute to the direction of future research in weaned piglets.

Abstract
OBJECTIVE To analyze the genetic diversity of Pomacea canaliculata based on the mitochondria DNA cytochrome c oxidase subunit Ⅰ (mtDNA COⅠ) gene as a molecular marker in Lincang City of Yunnan Province, so as to provide the scientific data for monitoring Angiostrongylus cantonensis in local areas. METHODS The genotypes and polymorphisms of 38 specimens of P. canaliculata collected from Mengding Town of Lincang City were analyzed by sequencing COⅠ gene. The phylogenetic tree and genetic distances were produced based on the haplotypes from GenBank and the present study by using the neighbourjoining method with the software MEGA version 6.06. RESULTS Totally 31 sequences were acquired in the present study and they produced 3 unique haplotypes. Haplotype 1 showed a higher frequency compared to the others and it accounted for 83.9 % (26/31). The data showed that the least genetic distances ranged from 0 to 0.052 between P. canaliculata and 3 haplotypes, as well as the largest genetic distances ranged from 0.021 to 0.239 between Pila conica and 3 haplotypes. Otherwise, the analysis of the phylogenetic trees based on COⅠ gene sequences of P. canaliculata indicated that all of 3 haplotypes clustered into one big clade with that from Japan (GenBank accession number: AB433769), China (GenBank accession number: KT313034) and USA (GenBank accession number: EU523129), which owned the closet relationship amongst them. Their genetic relationships were distantly related to the GenBank's reference sequences of P. insularum (GenBank accession number: EF514942), P. camena (GenBank accession number: EF515059) and so on. CONCLUSIONS There is a P. canaliculata species in Lincang City of Yunnan Province as well as a high genetic diversity amongst the acquired 3 haplotypes in this study.

Abstract
AIM To analyse the humoral immune response in mice to nucleic acid vaccines (VR1012/HG-MSP1-17 for intracellular expression or VR1012/TPA/HG-MSP-17 for secretion) containing Plasmodium falciparum merozoite surface protein 1 (MSP1) 17 block gene and gene fragment of several T cell epitopes from MSA1, MSA2, RESA, IL-1 and TT. METHODS BALB/c or C57BL/6 mice received three times intramuscular immunization with 200 micrograms/100 microliters or 100 micrograms/100 microliters of VR1012/HG-MSP1-17 or VR1012/TPA/HG-MSP1-17 per mouse each time. Anti-HG or anti-MSP1-17 antibodies were monitored by indirect ELISA. RESULTS BALB/c and C57BL/6 mice immunized with 100 micrograms/100 microliters of VR1012/HG-MSP1-17 per mouse raised significantly anti-HG and anti-MSP1-17 antibodies, but the levels of antibodies were not high. BALB/c mice immunized with 200 micrograms/100 microliters of VR1012/HG-MSP1-17 per mouse raised higher anti-HG antibodies but not anti-MSP1-17 antibodies. BALB/c mice immunized with 200 micrograms/100 microliters of VR1012/TPA/HG-MSP1-17 per mouse raised low level of anti-HG antibodies only. CONCLUSION VR1012/HG-MSP1-17 is more immunogenic than VR1012/TPA/HG-MSP1-17.
