BACKGROUND Hepatitis B virus (HBV) infection is the most common and serious liver infection in the world. An estimated 350 million people are chronic carriers of this virus, of whom, more than 620,000 die from liver-related diseases annually. Due to the vaccination program, prevalence of HBV, particularly among the younger generation, is reported to have(More)
BACKGROUND Previous studies using cell culture systems for the replication of hepatitis C virus have opened new research dimensions, and paved the ways for further and detailed studies of the virus in vitro. OBJECTIVES The purpose of the present study was to cultivate hepatitis C virus in a cell culture system and evaluate viral amplification. MATERIALS(More)
BACKGROUND Chronic hepatitis C virus (HCV) infection is frequently associated with elevated serum iron markers. Polymorphisms in the hemochromatosis (HFE) genes are responsible for iron accumulation in most cases of hemochromatosis, and may play a role in HCV infection. OBJECTIVES We aimed to assess the prevalence of HFE gene polymorphisms in a group of(More)
Chronic hepatitis B is still a major public health issue despite the successful prophylactic vaccination attempts. Chronicity of hepatitis B virus (HBV) is mainly due to its ability to debilitate host's immune system. Therefore, major measures have been taken to stop this process and help patients with chronic hepatitis B infection recover from their(More)
BACKGROUND Hepatitis C virus (HCV) infection is one of the most prevalent infectious diseases responsible for high morbidity and mortality worldwide. Therefore, designing new and effective therapeutics is of great importance. The aim of the current study was to construct a DNA vaccine containing structural proteins of HCV and evaluation of its expression in(More)
Herpes simplex virus types 1 (HSV-1) and 2 (HSV-2) are members of the Herpesviridae family. About 40% to 80% of the world populations are infected with HSV and its prevalence is high in Iran. The high prevalence of this virus in the community and the ability of the virus in causing fatal diseases among immunocompromised patients, have encouraged studies to(More)
BACKGROUND Hepatitis delta virus (HDV) is dependent on the hepatitis B virus for transmission and propagation. Based on isolated HDV sequences from different parts of the world, at least three major different genotypes with different geographic distributions are suggested. Studies have shown that genotype 1 is the predominant genotype of HDV in different(More)
Anti-Hepatitis D Virus (HDV) among hepatitis B virus surface antigen (HBsAg) positive subjects has been reported from various countries such as Romania (1), Rus-According to studies carried out in Iran, HDV does not have a similar prevalence in different parts of the country. While the overall prevalence seems to have declined in Iran, studies demonstrated(More)
BACKGROUND AND OBJECTIVES The main cause of serious nosocomial infections is a Gram-negative pathogen known as Pseudomonas aeruginosa (P. aeruginosa). Carbapenems are widely used as an appropriate treatment for these infections, however resistance to these agents has been observed and is increasing. Metallo beta-lactamase (MBLs) enzyme is one of the main(More)
BACKGROUND Hepatitis C virus (HCV) infection is a significant health problem throughout the world. Chronic form of the disease is found in about 75% to 85% of the newly infected individuals. The chronic infection may lead to severe forms including chronic liver disease, cirrhosis and with a higher mortality rate, hepatocellular carcinoma. Since no vaccine(More)
