Spartina alterniflora Loisel. is one of the most invasive species in the world. However, little is known about the role of artificial mowing in its invasiveness and competiveness. In this work, we studied the effect of mowing on its interspecific interactions with native species Phragmites australis (Cav.) Trin ex Steud of the Yangtze Estuary, China. We calculated their relative neighbor effect...

Rhizobacterial communities associated with Phragmites australis (Cav.) Trin. ex Steud. in a hypersaline pond close to Wuliangsuhai Lake (Inner Mongolia - China) were investigated and compared with the microbial communities in bulk sediments of the same pond. Microbiological analyses have been done by automated ribosomal intergenic spacer analysis (ARISA) and partial 16S rRNA gene 454 pyrosequen...

The aim of this study was to evaluate the physicochemical and functional properties of the protein recovered from mechanically deboned chicken meat (MDM) obtained by surimi and pH shift processes. The final products were characterized for proximate chemical composition with the protein isolate show in low value of lipids and a higher value of proteins than the surimi. Among these proteins, frac...

To evaluate pathogenicity of 3 Chicken Anemia Virus isolates-CV1, CV2 and CV3 respectively - the current experiment carried out. After tittering of the viruses, 30 one day old SPF chicks were grouped and intramuscularly inoculated with each isolate in a separate group. Two other groups as positive and control groups were inoculate with a live vaccine virus and normal saline respectively. During...

in this study, the pathogenicity of a/ch/it/5093/1999 h7n1 which had been isolated from chicken during the outbreak in italy was assessed in chicken by experimental infection virus. ten spf chickens of four week-old were inoculated with this virus, and five chickens were inoculated with uninfected allantoic fluid. for determination of virus shedding, oropharyngeal and cloacal swabs were taken f...

A new strain of avian picornavirus was identified in fecal samples from broiler chickens in a commercial farm in the municipality of Benevides, Pará, Brazil. Genomic analysis showed it to have a nucleotide identity of 78.4% with the family Picornaviridae, genus Avisivirus, and species Avisivirus A, suggesting that this is a possible new strain within this species.

The interaction in the chick gut between Streptococcus faecium and its phage was examined. In conventional chicks, large numbers of S. faecium and phage were found in the cecum and smaller numbers were found in the anterior gut. In gnotobiotic chicks associated with S. faecium SY1 and its phage, there was no marked effect on bacterial numbers, but resistance to the phage rapidly developed. Depr...

We have performed muon spin relaxation and susceptibility measurements of CaV4O9 and CaV2O5, systems in which spin gap-like behavior has been found. We observe spin freezing in the two compounds below 12 K and 50 K, respectively. Our results indicate the possibility that a substantial fraction of the vanadium magnetic moment is not in a spin singlet state at low temperatures in either material....
