We studied the prevalence of swine salmonellosis and PFGE genotype of isolates in Gunma Prefecture,Japan. Between 2005 and 2008, swine salmonellosis was confirmed in 430 of 2,707,402 (0.02%) swine atslaughterhouses. All isolates were identified as deriving from Salmonella Choleraesuis, biotype Choleraesuis (negativefor H2S production). We used 30 bacterial strains from 15 farms that had experienced outbreaks in 2006 and 2007. Allstrains were susceptible to various antibiotics such as cephems (cefotaxime), fluoroquinolones (norfloxacin andciprofloxacin), and fosfomycin. On the other hand, all strains were resistant to tetracycline (TC), and 29 of 30 (97%)strains were resistant to streptomycin (SM). The most predominant profiles …

Virus infection requires the interaction of a virus protein with the host-cell receptor. The Influenza A virusreceptor consists of sialic acid linked to the galactose unit in a α 2,3 or α 2,6 conformation. Various types of thesereceptors are expressed differently on the epithelial lining of various animal species. Here we characterized the typesof receptors that are expressed in the upper and lower respiratory tracts of cow, buffalo, pig and quail. Our findingsdemonstrate that SA α 2,6-gal linked receptors for human influenza viruses are present in the lower respiratory tractof cow and buffalo, while the SA α 2,3-gal linked receptors …

The present study was undertaken to determine the influence of sperm:oocyte ratio at fertilization in vitrousing frozen boar semen on fertilization rates and subsequent embryo development and quality in pig. Cumulusoocytecomplexes (COCs) were collected from porcine ovaries and then matured in vitro. After 44 hours of culture,matured oocytes were fertilized for 6 hours with three different sperm:oocyte ratios (1000:1, 2000:1, and 4000:1).Presumptive zygotes were fixed at 18-20 hours post-fertilization and then examined for sperm penetration andmonospermy rates. The developmental competence, in terms of cleavage and blastocyst rates, and the blastocystquality were evaluated at 48 and 168 hours post-fertilization, respectively. Sperm …
