In this study, restriction fragment length polymorphisms (RFLPs) were identified with an immunoglobulin variable heavy chain region (Ig VH) probe and the inheritance of the polymorphisms was analyzed in families. Linkage within the VHII gene cluster and between the VHII and Ig CH genes was investigated by lod (logarithm of odds) score analysis. In addition, the position of the VHII genes was de...

In the west of Scotland use of a single intragenic restriction fragment length polymorphism (F9(VIII)/TaqI) allowed definitive genetic counselling for 45% of females at risk of being carriers for haemophilia B. Two further intragenic RFLPs, F9(VIII)/XmnI) and F9(VIII)/DdeI, have been applied to this population and by using all three polymorphisms the carrier status could be determined in 68% of...

Myxomatosis, a lethal systemic disease of European rabbits (Oryctolagus cuniculus), is caused by Myxoma Virus (MV). The entire genome of the MV has been sequenced, allowing a systemic survey of the functions of a large number of putative pathogenic factors. The data present in literature have shown that myxoma virus is characterized by a high degree of genetic stability. Aim of this study was t...

Most species of Ceratocystis sensu stricto are virulent pathogens of a wide variety of plants including forest and fruit trees, sweet potato, pineapple and sugar cane. Confusion exists regarding the taxonomy of the species in this genus. The aim of this study was to develop a rapid and reliable PCR-based RFLP identification method and to consider phylogenetic relationships among the betterknown...

Genetic analysis of noninvasively collected bird feathers is of growing importance to avian ecology; however, most genetic studies that utilize feathers make no mention of the need to verify their species of origin. While plumage patterns and collection location often are indicative of species identity, broad-scale feather collections may require definitive species identification prior to analy...

We characterized 38 Helicobacter isolates, including 22 from gastric biopsy samples obtained from 14 rhesus monkeys and single isolates from 16 monkeys in a different colony. Biochemical profiles of these isolates were nearly identical to that of Helicobacter pylori ATCC 43504. Restriction fragment length polymorphism (RFLP) analysis indicated that each infected monkey harbored one to four stra...
