A new Salmonella serovar S.III b 58:z10:z53:Rz50

A new Salmonella serovar S.III b 58:z10:z53:Rz50 was isolated from the water samples of Ashida river, Fukuyama city, Japan. Its antigenic structure is described.     

Salmonella enteritidis Serotype 501, 2, 3: z4, z24: -

Characteristics of a new Salmonella serotype, subgenus IV, are reported. Culture 5534-68 was recovered from the intestinal tract of Anolis biporcatus, an arboreal lizard found in deep forest tracts in Panama Province, Republic of Panama. The antigenic composition of this new serotype was found to be 50(1, 2, 3):z(4), z(24):-.     

Chromatographic separation and spectroscopic characterization of the e/z isomers of acrivastine

A reverse phase high performance liquid chromatography (HPLC) method has been developed for the separation of two geometric isomers of Acrivastine using crude reaction mixture. The resolution between two isomers was found more than 2.9. The geometric isomers have been isolated by preparative HPLC and characterized by spectroscopic techniques, such as NMR, infrared, and MS. The developed method has been validated for the determination of Z‐isomer in Acrivastine. The limit of detection and limit of quantification of the Z‐isomer were 0.05 and 0.2 μg/ml, respectively. The developed method is precise, linear, accurate, rugged and robust for its intended use. Chirality, 2011. © 2011 Wiley‐Liss, Inc.
