Campylobacter jejuni recovered from patients with Guillain-Barré syndrome (GBS) in different geographical locations and bearing different heat-labile and heat-stable antigens were found to have identical amino acid sequences in their flagellar flaA short variable region, suggesting that it may be a potentially useful marker for GBS association.

The NADC30-like strains of porcine reproductive and respiratory syndrome virus (PRRSV) are characterized by a 131-amino-acid deletion in nonstructural protein 2 (NSP2). Here, we report the complete genome sequence of a recombinant NADC30-like PRRSV strain, SCnj16, that exhibits the molecular marker of the Chinese highly pathogenic PRRSV (HP-PRRSV) in NSP2.

Objective(s) The aim of this study was to characterize the hepatitis B virus surface protein genotypes and sequence variations among hepatitis B virus surface antigen (HBsAg) positive chronic patients in Hormozgan province, south of Iran. Materials and Methods A total of 8 patients enrolled in this study. The surface gene was amplified and directly sequenced. Genotypes and nucleotide/amino a...

An experiment was conducted to study the effects of substitution soybean meal (SBM) with canola meal (CM) and formulated diets based on total and digestible amino acid on performance, egg quality, organs weight and blood parameters of laying hens from 73 to 83 weeks of age. A total of 128 laying hens were distributed by completely randomized design in a 2×2 factorial arrangement with 2 protein ...

Background and Aims: The aim of this study was to determine the correlation between the hepatitis B virus surface Ag (HBsAg) genotypes and variations in the clinical/serological pictures among HBsAg positive chronic patients from South Khorasan province of Iran. Methods: Twenty-five patients were enrolled in this study. The HBs Ag gene was amplified and was directly sequenced. Genotypes and nuc...

pistacia khinjuk (stocks) is a native species that, along with p. atlantica, is widely distributed from eastern to western iran through the makran zone, zagros mountains and the sanandaj-sirjan zone, ranging from 50 to 3300 m above sea level. the identification of resistance gene analogs holds great promise for developing resistant plants. a pcr approach with degenerate primers designed from co...

Recent advances in the knowledge of antibody structure have prompted much discussion of the number and arrangement of the genes which code for immunoglobulin light and heavy chains (6, 12). In no case, however, have immunoglobulin structural genes been located in a genetic linkage map of any organism. Knowledge of the linkage groups containing immunoglobulin structural loci would be useful in f...
