background: infection with parvovirus b19 may cause fetal losses including spontaneous abortion, intrauterine fetal death and non-immune hydropsfetalis. the aim of this study is to determine the frequency of parvovirus b19 in formalin fixed placental tissues in lost fetuses using real-time pcr method.   methods : in this cross-sectional study, 100 formalin fixed placental tissues with unknown c...

Background: Human parvovirus B19 was known as one of the possible cause of mild respiratory tract diseases in previous studies. However, there are some reports of acute obstructive respiratory disease and severe pneumonia. The purpose of current study was to assess the prevalence and clinical features of parvovirus B19 in respiratory infection.    Methods: This study was conducted on...

Background and Aims: Human parvovirus B19, a member of the parvoviridae family, with single-stranded DNA is a very minute non-enveloped virus. B 19 virus is mostly transmitted via the respiratory tract but some studies have been reported which B19 virus can be transmitted through blood and/or blood products. The aim of this study was to evaluate the prevalence of B19 among blood donors in Tehra...

human parvovirus b19 is a very common viral infection especially in school-aged children. the infection during pregnancy can affect the fetus due to lack of mother's immunity. although, there is still no evidence of fetal teratogenic effects with parvovirus b19, but non-immune fetal hydrops and abortion may be caused by vertical transmission of the virus during pregnancy. this study was aimed t...

OBJECTIVE To investigate the association of human parvovirus B19 infection with the onset of acute lymphoblastic leukaemia and its effect on TEL-AML-1 fusion gene and the presence of mutant P53. METHODS The case-control study was conducted at Basrah Hospital for Paediatrics and Gynaecology, Basrah, Iraq, from May 2009 to April 2010. A total of 100 blood samples were collected from 40 newly di...

Human parvovirus B19 infection was studied in 60 thalassemic patients in Thailand. Seroprevalence, persistence of parvovirus B19 and their genotypes were identified in blood samples. Prevalence of anti-parvovirus B19 IgG and DNA found in thalassemic patients were 38% and 13%, respectively. Anti-parvovirus B19 IgM could be detected in 4% of these positive anti-parvovirus B19 IgG patients. The se...

INTRODUCTION Human parvovirus B19 causes a wide range of complications in pregnant women including abortion, severe fetal anemia, non-immune hydrops fetalis, and even intrauterine fetal death. However, there is a dearth of information on the prevalence of the virus among pregnant women in southwestern Nigeria. METHODOLOGY Blood samples were collected from 231 pregnant women and screened for a...

Background and Aims: Human parvovirus B19 may transmit to the fetus via the placenta during pregnancy and cause serious complications such as severe fetal anemia, non-immune hydrops fetalis, and even intrauterine fetal death. The aim of this study was to determine the seroprevalence of parvovirus B19 antibodies among young women, Sanandaj, Iran. Materials and Methods: Ninety young women (15-40 ...
