Abstract
The placenta is a selective maternal-fetal barrier that provides nourishment and protection from infections. However, certain pathogens can attach to and even cross the placenta, causing pregnancy complications with potential lifelong impacts on the child's health. Here, we profiled at the single-cell level the placental responses to three pathogens associated with intrauterine complications-Plasmodium falciparum, Listeria monocytogenes, and Toxoplasma gondii. We found that upon exposure to the pathogens, all placental lineages trigger inflammatory responses that may compromise placental function. Additionally, we characterized the responses of fetal macrophages known as Hofbauer cells (HBCs) to each pathogen and propose that they are the probable niche for T. gondii. Finally, we revealed how P. falciparum adapts to the placental microenvironment by modulating protein export into the host erythrocyte and nutrient uptake pathways. Altogether, we have defined the cellular networks and signaling pathways mediating acute placental inflammatory responses that could contribute to pregnancy complications.

Abstract
Listeria monocytogenes is a Gram-positive facultative intracellular pathogen that can cause severe invasive infections upon ingestion with contaminated food. Clinically, listerial disease, or listeriosis, most often presents as bacteremia, meningitis or meningoencephalitis, and pregnancy-associated infections manifesting as miscarriage or neonatal sepsis. Invasive listeriosis is life-threatening and a main cause of foodborne illness leading to hospital admissions in Western countries. Sources of contamination can be identified through international surveillance systems for foodborne bacteria and strains' genetic data sharing. Large-scale whole genome studies have increased our knowledge on the diversity and evolution of L. monocytogenes, while recent pathophysiological investigations have improved our mechanistic understanding of listeriosis. In this article, we present an overview of human listeriosis with particular focus on relevant features of the causative bacterium, epidemiology, risk groups, pathogenesis, clinical manifestations, and treatment and prevention.

Abstract
OBJECTIVE To describe maternal risk factors, presentations, peripartum findings, and pregnancy outcomes in Listeria monocytogenes-infected women. METHODS A retrospective descriptive case review. The records of 51 pregnant women infected with listeriosis who delivered infants between February 1, 2016 and February 28, 2018 at three academic hospitals in Johannesburg, South Africa, were included. The diagnosis of listeriosis was made on maternal/neonatal-sampled blood or tissue cultures. RESULTS Forty-eight (82.3%) Listeria infections of maternal and neonatal listeriosis were diagnosed on blood culture. The median gestational age at diagnosis was at a preterm gestation of 33 (20-43) weeks. Twenty-eight women (54.9%) had normal vaginal deliveries. Precipitous labor was described in 18 (39%) of these women. Fetal distress was the indication for cesarean section in 22 (41.2%) women. Meconium-stained amniotic fluid was found in 21 (61.7%) women at the time of delivery. The category of very low birth weight had 14 (27.4%) neonates with an Apgar score of less than 7 at 5 min. Maternal morbidities included chorioamnionitis (3 [5.8%]) and puerperal infections (7 [13.7%]). The HIV-positive anemic women had a tendency towards listerial infections. CONCLUSIONS Symptoms of listeriosis were non-specific and diagnosis was detected on blood culture sampling. Risk factors included HIV seropositivity and were associated with puerperal infections and anemia.

Abstract
Infection with Listeria monocytogenes during pregnancy is associated with miscarriage, preterm birth, and neonatal complications, including sepsis and meningitis. While the risk of these conditions is thought to be greatest during the third trimester of pregnancy, the determinants of fetoplacental susceptibility to infection, the contribution of gestational age, and the in vivo progression of disease at the maternal-fetal interface are poorly understood. We developed a nonhuman primate model of listeriosis to better understand antecedents of adverse pregnancy outcomes in early pregnancy. Four pregnant cynomolgus macaques (Macaca fascicularis) received a single intragastric inoculation between days 36 and 46 of gestation with 107 CFU of an L. monocytogenes strain isolated from a previous cluster of human listeriosis cases that resulted in adverse pregnancy outcomes. Fecal shedding, maternal bacteremia, and fetal demise were consistently noted within 7 to 13 days. Biopsy specimens of maternal liver, spleen, and lymph node displayed variable inflammation and relatively low bacterial burden. In comparison, we observed greater bacterial burden in the decidua and placenta and the highest burden in fetal tissues. Histopathology indicated vasculitis, fibrinoid necrosis, and thrombosis of the decidual spiral arteries, acute chorioamnionitis and villitis in the placenta, and hematogenous infection of the fetus. Vascular pathology suggests early impact of L. monocytogenes infection on spiral arteries in the decidua, which we hypothesize precipitates subsequent placentitis and fetal demise. These results demonstrate that L. monocytogenes tropism for the maternal reproductive tract results in infection of the decidua, placenta, and the fetus itself during the first trimester of pregnancy. Although listeriosis is known to cause significant fetal morbidity and mortality, it is typically recognized in the third trimester of human pregnancy. Its impact on early pregnancy is poorly defined. Here we provide evidence that exposure to L. monocytogenes in the first trimester poses a greater risk of fetal loss than currently appreciated. Similarities in human and nonhuman primate placentation, physiology, and reproductive immunology make this work highly relevant to human pregnancy. We highlight the concept that the maternal immune response that protects the mother from serious disease is unable to protect the fetus, a concept relevant to classic TORCH (toxoplasmosis, other, rubella, cytomegalovirus, and herpes) infections and newly illuminated by current Zika virus outbreaks. Studies with this model, using the well-understood organism L. monocytogenes, will permit precise analysis of host-pathogen interactions at the maternal-fetal interface and have broad significance to both recognized and emerging infections in the setting of pregnancy.

Abstract
BACKGROUND Listeria monocytogenes usually causes mild maternal illness, but can be devastating to the fetus. CASE Listeriosis in a pregnant patient successfully treated with empiric antibiotic therapy is described. After induced delivery, despite severe placental infection, a healthy infant was born. Additionally, archived placental specimens with similar pathological manifestation were evaluated for evidence of L. monocytogenes. CONCLUSION It is important to emphasize the value of associating maternal data and clinical and laboratory findings of the newborn with the pathologic placental findings to get better results in the etiologic diagnosis of the listeriosis.

Abstract
Listeria is commonly found in processed and prepared foods and listeriosis is associated with high morbidity and mortality. Preventative measures are well prescribed and monitoring and voluntary recall of contaminated products has resulted in a 44% reduction in the prevalence of perinatal listeriosis in the USA. Pregnant women are at high risk for listeriosis, but symptoms are non-specific and diagnosis is difficult. The intracellular life-cycle of Listeria protects the bacterium from host innate and adaptive immune responses. Antibiotic treatment requires agents able to penetrate, distribute, and remain stable within host cells. Prolonged use of high-dose ampicillin can significantly improve neonatal outcome.

Abstract
Listeria monocytogenes is an alimentary infection which can be extremely dangerous for pregnant women. A 34-year-old pregnant woman was hospitalized with fetal cardiac rate alterations and influenza-like symptoms. A caesarean section due to fetal distress was performed. A maternal-fetal listeriosis diagnosis was possible only after the birth through bacteriological and histological examination on both the placenta and the newborn.

Abstract
The lung biopsy is an established procedure to procure a pathologic diagnosis in a child with a suspected pneumonic process of undetermined etiology. Improvements in pediatric anesthesia and surgery have reduced the operative complications to a minimum. A biopsy can usually be taken through a small intercostal incision when localization is not especially important in a patient with diffuse changes (see Chapter 1). The alternative method for tissue sampling is the endoscopic transbronchial biopsy. There is less risk to the patient, but the specimen is smaller and crush artifacts from the instrument are more common.

Abstract
Listeria monocytogenes is one of the leading foodborne pathogens and has been implicated in numerous outbreaks in the last 2 decades. Immunocompromised populations are usually the most susceptible to Listeria infections. Although the pathogenic mechanism is a complex process, significant progress has been made in unravelling the mechanism in recent years. It is now clear that numerous extracellular and cell-associated proteins, such as internalin, listeriolysin, actin polymerization protein, phospholipase, metalloprotease, and possibly p60 proteins, are essential for L. monocytogenes entry into mammalian cells, survival inside the phagosome, escape into the cytoplasm, and cell-to-cell spread. Other proteins may be responsible for growth and physiology or to maintain the structural integrity of the bacteria. Monoclonal and polyclonal antibodies have been developed against many of those antigens or their synthetic derivatives that have helped greatly to determine the structure and function of these antigens. The antibodies were also used for the diagnosis and detection, immunocytochemical staining, and serotyping of Listeria. Humoral immune response to live L. monocytogenes cells was examined in naturally or experimentally infected hosts. Studies revealed that only extracellular antigens induced the humoral response, whereas cell-associated antigens had apparently no response. It is speculated that during the occasional bacteremic phase, L. monocytogenes releases extracellular antigens that are then processed by the immune system for antibody production. As L. monocytogenes is an intracellular pathogen, the cell-associated antigens are not persistent in the blood circulation and thus fail to stimulate the humoral immune response.

Abstract
Listeria monocytogenes has been increasingly recognized as a cause of intrauterine sepsis with associated perinatal wastage. The condition is mostly acquired through dietary intake and appropriate advice should be given to all pregnant women. The most common presentations in pregnancy include premature labour, an influenza-like illness and reduced fetal movements. In this report, we present a series of 24 cases of perinatal listeria infection presenting to either our obstetric or neonatal units and confirmed by the microbiology department of the hospital. In particular, we wish to highlight 3 cases in which antenatal diagnosis and aggressive therapy was associated with a successful outcome. Amongst the remaining 21 cases in which an antenatal diagnosis was not made, there were 5 perinatal deaths and 1 mid-trimester loss at 18 weeks. Clinicians must maintain a high index of suspicion for listeria, particularly in gravid patients who present with fever in the setting of a persistent 'flu-like' illness and premature labour. Once suspected, appropriate specimens for listeria culture should include blood, cervical swabs and midstream urine. Empirical antibiotic therapy with amoxicillin should be instituted while waiting for culture results in patients with possible Listeria monocytogenes sepsis.
