A successful pregnancy is characterised by an increase in Th2 cytokines and suppression of Th1 cytokine production. A Th1 to Th2 cytokine shift is also observed in the disease progression of HIV infection. Highly active antiretroviral therapy (HAART) suppresses HIV viremia, increases CD4+ cell counts and counteracts the Th1 to ...

There is an increasing amount of evidence suggesting a systemic link between periodontal disease in the pregnant mother and pre-term low birth weight (PLBW). Severe periodontitis affects at least 10% of the general population. The aetiology of periodontitis is essentially a bacterially induced inflammatory reaction within the attachment surrounding the ...

Caenorhabditis elegans has emerged as a powerful model system for studying the biology of the synapse. Here we describe a widely used assay for synaptic transmission at the C. elegans neuromuscular junction. This protocol monitors the sensitivity of C. elegans to the paralyzing affects of an acetylcholinesterase inhibitor, aldicarb. Briefly, ...

BACKGROUND: Over 95% of fetal complications (fetal hydrops and death) occur within 12 weeks following acute parvovirus B19 (B19) infection in pregnancy. Therefore, weekly fetal ultrasound monitoring is generally recommended for this time period. However, in the majority of women, typical symptoms of acute infection (rash or arthropathy) are absent, ...

Diagnosis of fetal infection has depended on identification of pathogens by means of microbiological cultures, immunologic techniques, and special molecular biology techniques that can identify organisms known or suspected of being associated with adverse outcomes of pregnancy. Rubella, cytomegalovirus (CMV), herpes simplex virus (HSV), and human immunodeficiency virus (HIV), for ...

In September 2005, we published an article on Chickenpox, pregnancy and the newborn. One of the issues it considered was fetal varicella syndrome, an uncommon but potentially fatal consequence of in-utero chickenpox infection. We reported evidence suggesting that contracting maternal chickenpox within the first 28 weeks of pregnancy can lead ...

The entomopathogenic nematode Steinernema carpocapsae is mutualistically associated with the bacterium Xenorhabdus nematophila. Infective Juveniles (IJs) transport X. nematophila cells that provide them with good conditions to reproduce within the insect. In the laboratory, long term stationary-phase culture conditions sometimes lead X. nematophila's variant 1 cells, which were previously isolated ...

Pregnant women who report possible exposure to a viral illness can present a clinical predicament for obstetric providers. Although some viruses are benign in pregnancy, others can have serious consequences. Parvovirus B19, the causative agent of fifth disease, is one of the more serious of the common viruses. Understanding the ...

BACKGROUND: Antiretroviral therapy is recommended for human immunodeficiency virus (HIV)-infected patients during pregnancy to reduce the vertical transmission to the newborn. Complications from this therapy are uncommon. CASE: A 38-year-old HIV-positive pregnant woman was treated with lamivudine and zidovudine. At 28 weeks of gestation, her hemoglobin had fallen to 4.6 ...

Approximately 22% of pregnant women are infected with herpes simplex virus (HSV)-2, and 2% of women will acquire HSV during pregnancy. Remarkably, up to 90% of these women are undiagnosed because they are asymptomatic or have subtle symptoms attributed to other vulvovaginal disorders. Diagnosis of genital herpes relies on laboratory ...

Leishmania infantum, an etiologic agent of zoonotic visceral leishmaniasis, is widespread among foxhounds in the United States. Although sand flies are widely distributed throughout the United States, epidemiological data do not support a major role for sand flies in the transmission of L. infantum in foxhounds in this country. Congenital ...

In utero viral infections have been associated with an adverse pregnancy outcome and may have a causative role in the unexplained fetal death file. Parvovirus B19 and cytomegalovirus are among the most common pathogens implicated in fetal loss cases. Parvovirus B19 has been reported to account for cases of spontaneous ...

Acute infections by the protozoan Toxoplasma gondii during pregnancy (gestational toxoplasmosis) are known to cause serious health problems to the fetus (congenital toxoplasmosis). In Brasília, there have been few studies on the incidence of toxoplasmosis. This report summarizes a retrospective study performed on 2,636 selected pregnant women attended by the ...
Mohlala Boshishi K F - - 2005
BACKGROUND: In the absence of interventions and breast-feeding, the in utero transmission rate of human immunodeficiency virus (HIV) is estimated to be 10%-15%, and the role that amniotic fluid (AF) plays in this is unclear. OBJECTIVES: Levels of cytomegalovirus (CMV) in AF and levels of HIV-1 in AF, maternal blood, ...
Tan Michael Paul - - 2006
Varicella infection during the first and second trimester of pregnancy may increase the risk for congenital varicella syndrome 0.5-1.5% above the baseline risk for major malformation. Third trimester infection may lead to maternal pneumonia which can be life threatening if not treated appropriately. Varicella-zoster immune globulin (VZIG) should be administered ...
Kupka Roland - - 2005
BACKGROUND: Among HIV-infected pregnant women, low selenium status may increase risk of mother-to-child transmission (MTCT) of HIV and poor pregnancy outcomes (low birthweight, small for gestational age, preterm birth, and fetal death) through several mechanisms, such as by promoting maternal HIV disease progression, viral shedding in the genital tract, and ...

Infection with the protozoan parasite Neospora caninum is an important cause of abortion in cattle. A major source of infection is transplacental transfer of the parasite from mother to offspring during pregnancy. This study describes investigations on the immunisation of outbred Qs mice before pregnancy with live or a crude ...

Chlamydophila abortus is one of the major causes of infectious abortion in pregnant sheep (enzootic abortion of ewes or EAE) worldwide. Organisms shed in infected placentas and uterine discharges at lambing time are the main sources of environmental contamination, responsible for transmission to susceptible animals and possible human contacts. In ...

OBJECTIVE: To investigate whether there is any correlation between Helicobacter pylori infection and platelet counts during pregnancy. METHODS: One hundred and twenty pregnant women without any complications were evaluated. Platelet counts were determined during pregnancy and postpartum. H. pylori infection was assessed by the detection of serum antibodies at the ...

During human gestation, viruses can cause intrauterine infections associated with pregnancy complications and fetal abnormalities. The ability of viruses to spread from the infected mother to the fetus arises from the architecture of the placenta, which anchors the fetus to the uterus. Placental cytotrophoblasts differentiate, assume an endothelial phenotype, breach ...
Yeo Alvin - - 2005
BACKGROUND: Recent studies have suggested that subclinical infection may be an important cause of low birth weight. Campylobacters are important human pathogens, causing septicemia and occasionally abortion, premature labor, or severe perinatal infection. The potential role of oral species of Campylobacter in mediating adverse pregnancy outcomes in animal models has ...
Williams R H - - 2005
Recent research suggests that vertical transmission may play an important role in sustaining Toxoplasma gondii infection in some species. We report here that congenital transmission occurs at consistently high levels in pedigree Charollais and outbred sheep flocks sampled over a 3-year period. Overall rates of transmission per pregnancy determined by ...
