Parvovirus B19-introduction Parvovirus B19 (B19) is an erythrovirus and recent studies have classified B19 as a genotype 1 erythrovirus with genotypes 2 (erythrovirus K71 or A6) and 3 (erythrovirus V9) also present in the human population. B19 is a significant human pathogen which can cause foetal hydrops and foetal death if maternal infection, followed by transplacental QA :1 foetal infection,...

Modulation of the maternal-foetal immune response, designed to benefit the gestation of an individual whose genetic material is foreign to that of the mother, since 50% is of paternal origin, is a unique, highly complex biological process involving the father, mother and child. The first signals emitted by the seminal fluid already promote the beginning of immune adaptation, in which the antige...

The nature and extent of the transmission of immunity by the mammary gland from the mother to her offspring is related to the rate of transmission during foetal life: in mammals with immunoglobulin (Ig) permeable placenta, the systemic immunity of the mother is transferred during foetal life; in contrast, in artiodactyls with Ig impermeable placenta, systemic immunity is transmitted just after ...

While there is strong evidence that maternal smallpox infection can cause foetal loss, it not clear whether infections were a demographically important of stillbirths historically. In this paper, we use parish-level data from the Swedish Tabellverket set for 1780–1839 to test effect on quantitatively, analysing periods before and after introduction vaccination in 1802. We find was major 1820, b...

Franz J., A. Milon, H. Salmon: Synthesis of Immunoglobulins IgG, IgM and IgA during the Ontogeny of Foetal Pigs. Acta vet. Bmo, 51,1982: 23-30. Using the modified micro-ELISA (enzyme linked immunosorbent assay) on the competitive principle immunoglobulins IgG, IgM and 19A were demonstrated in the blood serum, amniotic fluid and organ suspensions of 50to 150-day old pig foetuses. The predominant...

The histopathological appearances of the thymus, lymph nodes, spleen, and gut-associated lymphoid tissue (tonsil, Peyer's patches, and appendix) in cases of the combined immunity-deficiency syndrome are presented. The appearance of tissues remaining after foetal thymic transplants and the effects of such transplants on the morphology of lymph nodes are also discussed. Although thymic appearance...

Background: To study the morphological development and histomorphometry of foetal and adult ovaries in Kano brown goats. Materials and Methods: Fifty-one foetal and fourteen adult ovaries obtained from slaughtered Kano brown does in Nsukka abattoir were used for this study. The ages of the adult does were determined by dentition and foetuses by crown rump length method. The foetal and adult ova...
