genome-wide survey of signature of positive selection in khuzestani and mazandrani buffalo breeds
identification of selection targeted genomic regions is one of the most challenging areas of research in animal genetics, particularly in livestock. we carried out a genome-wide scan for signatures of positive selection to identify genomic regions that had been under selection in iranian khuzestani and mazandrani buffalo breeds. a total of 148 water buffalo from khuzestani (n=121) and mazandran...
متن کاملDraft genome sequences of Actinobacillus pleuropneumoniae serotypes 2 and 6.
Actinobacillus pleuropneumoniae is a bacterial pathogen that causes highly contagious respiratory infection in pigs and has a serious impact on the production economy and animal welfare. As clear differences in virulence between serotypes have been observed, the genetic basis should be investigated at the genomic level. Here, we present the draft genome sequences of the A. pleuropneumoniae sero...
متن کاملA Genome-Wide Identification of Genes Undergoing Recombination and Positive Selection in Neisseria
Currently, there is particular interest in the molecular mechanisms of adaptive evolution in bacteria. Neisseria is a genus of gram negative bacteria, and there has recently been considerable focus on its two human pathogenic species N. meningitidis and N. gonorrhoeae. Until now, no genome-wide studies have attempted to scan for the genes related to adaptive evolution. For this reason, we selec...
متن کاملActinobacillus pleuropneumoniae disease and serology
Actinobacillus pleuropneumoniae is a primary bacterial pathogen causing swine respiratory disease and has been described in most major swine-producing regions of the world. Preliminary diagnosis of A. pleuropneumoniae is based on clinical signs and gross pneumonic lesions. Isolating and identifying the causative bacteria confirms the diagnosis. Twelve serotypes of A. pleuropneumoniae and a numb...
متن کاملActinobacillus pleuropneumoniae for Use in Live Vaccines
Clonal, noniridescent mutants ofActinobaciUlus pleuropneumoniae serotypes 1 and 5 were isolated following chemical mutagenesis with ethyl methanesulfonate. The absence of any detectable capsule was confirmed by inhibition radioimmunoassay. There were no differences between the parent and mutant strains in lipopolysaccharide or protein electrophoretic profiles or in hemolytic activity. There was...
