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.

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 ...

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

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

Infection-acquired versus vaccine-acquired immunity in an SIRWS model [PDF]

open access: yes, 2017
Despite high vaccine coverage, pertussis has re-emerged as a public health concern in many countries. One hypothesis posed for re-emergence is the waning of immunity.

Seroprevalence of measles and natural rubella antibodies among children in Bangui, Central African Republic

open access: yesBMC Public Health, 2011
Background Passively acquired maternal antibodies are necessary to protect infants against circulating measles virus until they reach the eligible age of vaccination.

Variation in innate immunity in relation to ectoparasite load, age and season : a field experiment in great tits (Parus major) [PDF]

open access: yes, 2010
It remains largely unknown which factors affect the innate immune responses of free-living birds. Nevertheless, the degree of innate immunity may play a crucial role in an individual's survival as it procures the first defence against pathogens.

Comparative Serological Evaluation of The Maternal and Acquired Immunity of Newcastle Disease In chickens [PDF]

open access: yesBasrah Journal of Veterinary Research
Infectious avian, including Newcastle disease (ND), are a major concern in poultry husbandry. The primary method of preventing viral infections is immunization by vaccines to produce neutralizing antibodies.
