Sažetak
Haemophilus somnus is a pathogen frequently associated with infectious thromboembolic meningoencephalitis in cattle. Five strains of H. somnus were isolated from clinically infected cattle. In the Sudan the organism is associated with a clinical syndrome characterized by nervous manifestations. The strains were found to be morphologically and serologically different as determined by cultural and biochemical characteristics. In the present study, a polymerase chain reaction (PCR)- based randomly amplified polymorphic DNA (RAPD) method was used to amplify H. somnus DNA using arbitrary oligonucleotide primers. The method was able to detect the heterogeneity of amplified DNA from the strains of H. somnus. The scientific data presented in this study suggests that RAPDPCR could be used as a valuable tool in the study of the the molecular epidemiology of H. somnus isolated from clinical samples of naturally infected cattle.
