Marek’s disease (MD) is a lymphoproliferative disease of chickens characterized by lymphocyticinfiltration of various organs. The present study was an attempt to use polymerase chain reaction (PCR) tooptimize a rapid and reliable assay for detection of MDV genome. Detection of serotype 1 of MDV (MDV-1)was confirmed by presence of a 200 bp DNA fragment as a PCR product. Differentiation of MDV-1 ...

results the pellet of the 146s antigen of fmd virus serotype a was developed at a concentration of sucrose 50%. absorbance rate of the foot-and-mouth disease virus serotypes a at wavelengths of 240, 259 and 280 nm was 1.238, 1.573 and 1.157, respectively. moreover, the amount of 146s antigen at the same wavelengths was 163.416, 207.636 and 152.724 μg/ml, respectively. the amount of purified pro...

The occurrence of viral co-infection is a common phenomenon in cultivated and native plant species and can alter the dynamics of virus infection. In this study, disease progress was examined in single and mixed infections of Cucumber mosaic virus (CMV) and Bean yellow mosaic virus (BYMV) by measuring the rate of symptom development, disease severity and area under disease progress curve on infe...

BACKGROUND: Caprine pox virus disease play an important role in major constraints to small ruminants production in Iran. OBJECTIVES: This study was conducted in different districts of Iran to determine the prevalence of goats pox virus disease in different age groups, sex and seasons in Black goats of Iran. METHODS: In this study skin lesions of male and female goats were collected randomly ...

Newcastle Disease (ND) is a major viral disease in Indonesia. It is an RNA virus belongs to Paramyxovirinae. It is well known that RNA virus is easily to mutate. In some cases, this mutation could generate virulence alteration. It is noted that mutation of NDV which has avirulent amino acid sequence on the cleavage site, could mutate to be virulent Newcastle Disease Virus (NDV). It is needed to...

Plum pox or sharka, a viral disease caused by Plum pox virus (PPV), severely affects the production of Prunus species in Europe. The first evidence of sharka was reported in Iran in 2000 . Due to the economic impact of this disease on crop production, recent advances in the term of  biology, epidemiology, and disease management are provided in this paper to assure awareness among growers and pr...

Foot-and-mouth disease (FMD) is a major infectious disease in livestock. The common clinical signs in cattle include epidermal vesicles that are majorly distributed around oronasal cavity, feet and teats. The aim of this report is to document an uncommon clinical form of the disease which comprises the occurrence of classic vesicular lesion in a rarely observed location of the horn vegetative t...
