background and aims: primary infections of rubella and human cytomegalovirus (hcmv) can lead to severe complications in pregnancy. the screening of rubella and hcmv in pregnant women is not routinely carried out in iran. this cross sectional study aimed to investigate the seroprevalence of hcmv and rubella infections in neonates with and without congenital defects. materials and methods: this s...

in order to estimate the mean of maternal antibody in calves against bhv-1 (bovine herpes virus type 1), this study was carried out in a population of calves from non-vaccinated dairy cattle at 2 livestock in qazvin province. one hundred thirteen sera out of 512 were collected from 1-4 months unvaccinated calves. we used blocking –percentage of maternal antibodies against bhv-1, which obtained ...

Background: Respiratory Syncytical virus infection is the most common cause of bronchiolitis and viral pneumonia in infancy. Objective: To investigate the placental transfer of RSV-specific IgG in Iranian mothers. Methods: The antibodies were measured in sera of 146 mother/newborn pairs using a commercially available indirect Enzyme Linked Immunosorbent Assay (ELISA). The studied subjects were ...

Background & Aims: Maternal infections with parvovirus B19 and cytomegalovirus (CMV) maybe associated with intrauterine fetal death. The aim of this study was to compare frequency of CMV & Parvovirus B19 Infections in intrauterine fetal death (IUFD) and normal pregnancy. Methods: In a case-control study in Afzalipour Hospital during 2006 placental biopsies were collected from 70 cases of IUFD a...

background: respiratory syncytical virus infection is the most common cause of bronchiolitis and viral pneumonia in infancy. objective: to investigate the placental transfer of rsv-specific igg in iranian mothers. methods: the antibodies were measured in sera of 146 mother/newborn pairs using a commercially available indirect enzyme linked immunosorbent assay (elisa). the studied subjects were ...

BACKGROUND Maternal antibodies can interfere with foot-and-mouth disease vaccination. In this study we determined whether intratypic heterologous vaccination could help to improve herd immunity. RESULTS In unvaccinated calves, a half-life of maternal antibodies of 21 days was determined. At two weeks of age, calves without maternal antibodies showed a good antibody response against both vacci...

Little is known about the maternal transfer of antibodies in natural host-parasite systems despite its possible evolutionary and ecological implications. In domestic animals, the maternal transfer of antibodies can enhance offspring survival via a temporary protection against parasites, but it can also interfere with the juvenile immune response to antigens. We tested the functional role of mat...

F4 enterotoxigenic Escherichia coli (ETEC) cause diarrhoea and mortality in piglets leading to severe economic losses. Oral immunization of piglets with F4 fimbriae induces a protective intestinal immune response evidenced by an F4-specific serum and intestinal IgA response. However, successful oral immunization of pigs with F4 fimbriae in the presence of maternal immunity has not been demonstr...
