The level and duration of RSV-specific maternal IgG in infants in Kilifi Kenya [PDF]

open access: yes, 2009
Background Respiratory syncytial virus (RSV) is the major cause of lower respiratory tract infection in infants. The rate of decay of RSV-specific maternal antibodies (RSV-matAb), the factors affecting cord blood levels, and the relationship between ...

Silent Reactivation of Varicella Zoster Virus in Pregnancy: Implications for Maintenance of Immunity to Varicella

open access: yesViruses, 2022
We encountered two cases of varicella occurring in newborn infants. Because the time between birth and the onset of the illness was much shorter than the varicella incubation period, the cases suggested that the infection was maternally acquired, despite

Placental and colostral transfer of antibodies reactive with enteropathogenic Escherichia coli intimins α, β, or γ

open access: yesJornal de Pediatria (Versão em Português), 2017
Objective: Intimins are protein adhesins of enteropathogenic Escherichia coli (EPEC) and enterohemorrhagic E. coli (EHEC) capable of inducing attachment and effacement lesions in enterocytes.

Support for viral persistence in bats from age-specific serology and models of maternal immunity. [PDF]

open access: yes, 2018
Spatiotemporally-localised prediction of virus emergence from wildlife requires focused studies on the ecology and immunology of reservoir hosts in their native habitat.

The Role of Maternally Acquired Antibody in Providing Protective Immunity Against Nontyphoidal Salmonella in Urban Vietnamese Infants: A Birth Cohort Study [PDF]

open access: yesThe Journal of Infectious Diseases, 2018
We found a high transfer ratio of anti-nontyphoidal Salmonella (NTS) antibodies from mothers to infants. Furthermore, despite a high seroincidence of NTS in infants, maternally acquired antibodies provided protection from seroconversion. Therefore, we propose prenatal immunization against NTS as a possible strategy for protecting infants from NTS ...

Kinetics of the neutralizing antibody response to respiratory syncytial virus infections in a birth cohort [PDF]

open access: yes, 2013
The kinetics of respiratory syncytial virus (RSV) neutralizing antibodies following birth, primary and secondary infections are poorly defined. The aims of the study were to measure and compare neutralizing antibody responses at different time points in ...

Passive and active immunity in infants born to mothers with SARS-CoV-2 infection during pregnancy: prospective cohort study

open access: yesBMJ Open, 2021
Objective To investigate maternal immunoglobulins’ (IgM, IgG) response to SARS-CoV-2 infection during pregnancy and IgG transplacental transfer, to characterise neonatal antibody response to SARS-CoV-2 infection, and to longitudinally follow actively and

Maternal Vitamin E Alters Passively Acquired Immunity of Chicks

open access: yesPoultry Science, 1978
Passively transferred antibody levels were significantly increased in plasma of two- and seven-day-old chicks when the dams were fed 150 and 450 p.p.m. vitamin E prior to immunization with Brucella abortus. However, if the hens were fed 90, 300 and 900 p.p.m. vitamin E before immunization, the chicks evidenced no increase in antibody titers relative to

Loss of Passively Acquired Maternal Antibodies in Highly Vaccinated Populations: An Emerging Need to Define the Ontogeny of Infant Immune Responses [PDF]

open access: yesThe Journal of Infectious Diseases, 2013
Protection against infectious diseases is provided to young infants by passive immunity through the transplacental transfer of immunoglobulin G during pregnancy and through immunoglobulin A in breast milk [1–7]. Despite the obvious benefits of these antibodies to the youngest infants, their levels wane over time, necessitating the development of active

Early-life hepatitis e infection in pigs: the importance of maternally-derived antibodies. [PDF]

open access: yesPLoS ONE, 2014
Passive immunity (PI), acquired through colostrum intake, is essential for piglet protection against pathogens. Maternally-derived antibodies (MDAs) can decrease the transmission of pathogens between individuals by reducing shedding from infected animals
