2. Passive acquisition of anti-Staphylococcus aureus antibodies by newborns via transplacental transfer and breastfeeding, regardless of maternal colonization
OBJECTIVE: To investigate the transmission of anti-Staphylococcus aureus (Sa) IgG, IgG1 and IgG2 via placental transfer and the transfer of IgA via the colostrum according to maternal Sa carrier status at delivery. METHODS: We evaluated anti-Sa IgG, IgG1 and IgG2 in maternal and cord sera and IgA in colostrum from a case (n=49, Sa+) and a control group (n=

3. Zika virus damages the human placental barrier and presents marked fetal neurotropism
An unusually high incidence of microcephaly in newborns has recently been observed in Brazil. There is a temporal association between the increase in cases of microcephaly and the Zika virus (ZIKV) epidemic. Viral RNA has been detected in amniotic fluid samples, placental tissues and newborn and fetal brain tissues. However, much remains to be determined con

4. Cutaneous neonatal herpes simplex virus infection type 2: a case report
Abstract Neonatal herpes is a serious condition. Newborns can be contaminated in utero via transplacental hematogenic transmission, upon delivery (the most frequent route), or during the postnatal period (indirect transmission). Optimal management requires prompt and accurate recognition, particularly in newborns, in order to prevent complications. Acyclovir

5. Diagnóstico sorológico e avaliação da ocorrência da transmissão vertical de Neospora caninum nos rebanhos bovinos Curraleiro e Pantaneiro / Serological diagnosis and evaluation of occurrence of vertical transmission of Neospora caninum in Curraleiro and Pantaneiro cattle
A neosporose bovina é uma enfermidade parasitária causada pelo protozoário intracelular obrigatório Neospora caninum (filo Apicomplexa, família Sarcocystidae), formador de cistos. Enfermidade de distribuição cosmopolita, a neosporose apresenta forte associação com o abortamento bovino, sendo N. caninum considerado o protozoário mais importante para

6. Experimental infection with Neospora caninum in young dogs (Canis familiaris), adults and in pregnant bitches. / Infecção experimental por Neospora caninum em cães (Canis familiaris) jovens, adultos e em cadelas gestantes.
The objectives of this study were to evaluate transplacental transmission of N. caninum in different stages of pregnancy (Exp I) and evaluate different bovine tis.sues as means of transmission of N. caninum in young dogs and adults (Exp II). In Exp I, Three dogs were inoculated with 108 tachyzoites of N. caninum in the third week of gestation, three at 6 six

7. Apoptose e proliferação celular em células trofoblásticas (linhagem BeWo) são diferentemente moduladas pelas cepas de Toxoplasma gondii
Transplacental transmission causes one of the most severe forms of infection with protozoan parasite Toxoplasma gondii. The ability of the parasite to survive intracellularly largely depends on the blocking of different proapoptotic signaling cascade of its host cell. However, alterations in the incidence of apoptosis, during pregnancy, are associated with a

8. Aspectos EpidemiolÃgicos da Neosporose Bovina em Rebanhos Leiteiros de Minas Gerais. / Epidemiology of bovine neosporosis in dairy herds of the Minas Gerais state 2008.
Neosporosis is a major cause of abortion in dairy and cattle worldwide. The global objective of this study was determined the frequency of infection in calves and heifers from dairy herds of Lavras, MG. For than two studies were carried, the first one was to establish the frequency of infection and to analysis risk factors to Neospora caninum in calves and h

9. Detection of of porcine parvovirus (PPV) in swine fetal tissues / Pesquisa da presença de parvovirus suino (PVS) em tecidos de fetos de suinos
Swine female reproductive quality is mainly measured by return to estrus, litter size, abortion, stillbirth and mummies. Porcine parvovirus (PPV) transplacental infection is associated to fetal death at different gestacional age, and mostly with fetal mummification due to abscence of fetal immunecompetence in early pregnancy. In late gestational age, immunec

10. Transplacental transmission of a leukemogenic murine leukemia virus.
Recombinant inbred BXH-2 mice spontaneously produce a B-tropic murine leukemia virus (MuLV) beginning early in life and have a high incidence of spontaneous myeloid leukemia. These traits are not characteristic of the progenitor strains (C57BL/6J and C3H/HeJ) or of 11 other recombinant inbred BXH strains. Genetic analysis has shown that the virus is not tran

11. Transplacental Transmission of Serotype-Specific Pneumococcal Antibodies in a Brazilian Population
The highest incidence of severe pneumococcal infections in children occurs in the first 6 months of life; however, immunization of infants with the existing polysaccharide vaccines is ineffective. We wished to determine the prevalence of immunoglobulin G (IgG) pneumococcal antibodies in unimmunized Brazilian mothers and their transplacental transmission to t
