Restriction Fragment Length Polymorphism Analysis (RFLP) of Some Streptomyces Strains from Soil
نویسنده
چکیده
To separate the unknown Streptomyces strains isolated from soil samples, the interspacer regions of 16S-23S rDNA of 14 isolates were amplified with PCR (polymerase chain reaction) and digested with three restriction endonucleases, namely, Bsp143I, HaeIII and MnlI. The restriction patterns were used for RFLP (restriction fragment length polymorphism) analysis. A dendrogram were constructed using the unweighed pair group method using arithmetic averages algorithm (UPGMA) after analysis restriction patterns. Five RFLP groups were obtained and one test strain was left as a single member group. RFLP profile indicated that unknown strains could be identified with data based on the interspacer region of 16S-23S DNA rapid and quickly.

Infectious bronchitis virus (IBV) is an acute and contagious viral disease of poultry that affects different systems, including the respiratory tract in particular. IBV causes major economic losses in the poultry industry globally. Due to antigenic variation of the causative agent, control of the disease is difficult. To control the disease, many vaccines that belong to different serotypes are...

BACKGROUND:Avian reoviruses (ARVs) are members of theOrthoreovirus genus; one of the 12 genera of the Reoviridaefamily. The ARVs are the cause of some important diseases inpoultry such as reovirus-induced arthritis, tenosynovitis,chronic respiratory disease, and mal-absorption syndrome.OBJECTIVES: In this study, the presence of ARVs in the Iranianbreeder flocks was investigated through reverse ...
