Introduction: Primaquine is vital for the management of liver-stage Plasmodium vivax and Plasmodium ovale malaria. However, primaquine effectiveness is dependent on various factors and differs between populations. Therefore, this study was conducted to identify factors that affect the length of stay and relapse during primaquine combination treatment in malaria-infected patients in the local setting. Materials and Methods: A retrospective study on the use of primaquine combination among P...

Neonatal herpes simplex virus infections are rare, but are associated with significant morbidity and mortality. Most newborns acquire herpes simplex virus infection in the peripartum period. For peripartum transmission to occur, women must be shedding the virus in their genital tracts symptomatically or asymptomatically around the time of delivery. There are evidence-based interventions in pregnancy to prevent the transmission to the newborn. Caesarean section should be performed in the presence of herpetic lesions, and antiviral prophylaxis in the last weeks of pregnancy is recommended to suppress genital tract herpes simplex virus at the time of delivery...

Marta C Nunes, Shabir A Madhi
The influenza virus circulates yearly and causes global epidemics. Influenza infection affects all age groups and causes mild to severe illness, and young infants are at particular risk for serious disease. The most effective measure to prevent influenza disease is vaccination; however, no vaccine is licensed for use in infants younger than 6 months old. Thus, there is a crucial need for other preventive strategies in this high-risk age group. Influenza vaccination during pregnancy protects both the mothers and the young infants against influenza infection...

The association between Zika virus infection during pregnancy and severe birth defects in infants has led to worldwide attention focused on the mechanisms of the disease and the prevention of future exposure. Surveillance efforts around the world continue with the goal of identifying and monitoring all potentially exposed women and their newborns. For infants who were born with congenital Zika syndrome (CZS) and their families, an uncertain future awaits. As infants who were born with CZS during the most recent outbreak enter their second year of life, new developments in the outcomes of the condition continue to unfold, providing some insight into the likely long-term sequalae...

Zikavirus (ZV) is a flavivirus transmitted by Aedes mosquitoes' bites. Sexual transmission is possible. Common ZV infection is asymptomatic or associates flu-like signs. Guillain-Barre syndrome following ZV infection is rare. Foetal infection, during the first trimester of pregnancy especially, can lead to severe neurological troubles. Diagnosis relies on blood and urine RT-PCR during the acute phase, and serology later in the disease. ELISA assays false positives are reported among patients infected with another flavivirus, whereas sero-neutralization is more specific...

Trichomonosis is an endemic disease in cattle that are reared under extensive conditions and bred by natural mating. It causes profound economic losses to the producers by increasing calving interval, increasing embryo losses, and decreasing pregnancy rates. The aim of this study was to determine whether Tritrichomonas foetus infections were absent from cattle in St. Kitts. Using the modified hypergeometric method, preputial samples from bulls (n = 78) were tested using the InPouch™ culture for presence of T...

REVIEW
Meghan S Vermillion, Sabra L Klein
Vaccination is the mainstay of preventative medicine for many infectious diseases. Pregnant women, unborn fetuses, and neonates represent three at-risk populations that can be simultaneously protected by strategic vaccination protocols. Because the pathogenesis of different infectious microbes varies based on tissue tropism, timing of infection, and host susceptibility, the goals of immunization are not uniform across all vaccines. Mechanistic understanding of infectious disease pathogenesis and immune responses is therefore essential to inform vaccine design and the implementation of appropriate immunization protocols that optimize protection of pregnant women, fetuses, and neonates...

Introduction Screening for specific sexually transmitted diseases (STDs) during pregnancy has been a longstanding public health recommendation. Prior studies have described associations between these infections and socioeconomic factors such as race/ethnicity and education. Objectives We evaluated the prevalence of STDs and the correlation socioeconomic factors have with the presence of these infections among pregnant women in the United States. Methods We conducted an analysis using self-reported data from 12,948 recently pregnant women from the Pregnancy Risk Assessment Monitoring System (PRAMS) in 5 states during 2009-2011...

Zika virus (ZIKV) infection during pregnancy can cause adverse fetal outcomes and severe irreversible congenital birth defects including microcephaly. Immunohistochemistry (IHC) is a valuable diagnostic tool for detecting ZIKV antigens in tissues from cases of fetal loss in women infected with ZIKV, and for providing insights into disease pathogenesis. As a result, there is increasing demand for commercially available ZIKV antibodies for use in IHC assays. ZIKV antibodies were selected and obtained from commercial sources to include both mouse and rabbit hosts, and a variety of antigenic targets...

Group B Streptococcus (GBS) is a normal inhabitant of recto-vaginal mucosae in up to 30% of healthy women. Colonization is a major risk factor for perinatal infection which can lead to severe complications such as stillbirth and neonatal invasive disease. Intra-partum antibiotic prophylaxis in colonized women is a safe and cost-effective preventive measure against early-onset disease in the first days of life, but has no effect on late-onset manifestations or on early maternal infection. Maternal immunization with capsular polysaccharide-based vaccines shows promise for the prevention of both early-onset and late-onset neonatal infections, although ability to prevent maternal colonization and ascending infection has been less studied...

Background: The early life microbiome contributes to immune development. Antibiotics during pregnancy alter the microbiome and may influence disease risks in the offspring. We investigated the relationship between maternal antibiotic exposure before and during pregnancy, and risk of childhood hospitalization with infection. Methods: We used population-based Danish national databases for pregnancies between 1995 and 2009. Infants were followed from birth until their first infection-related hospitalization, death, 14th birthday, emigration or end-2009...

Maternal morbidity, fetal mortality, and neonatal mortality are important indicators of maternal and child health. The study aimed to describe maternal and perinatal outcomes (low birth weight, prematurity, fetal and neonatal deaths, postpartum hospitalizations, and readmission of newborns) in a cohort of pregnant women whose deliveries were covered by the Brazilian Unified National Health System (SUS) in the city of São Paulo, Brazil, in the second semester of 2012. We obtained a retrospective cohort of 55,404 pregnant women with deterministic and probabilistic linkage of data from the Hospital Information System of the SUS (SIH/SUS), Information System on Live Births (SINASC), Mortality Information System (SIM), and National Registry of Health Establishments (CNES) databases...

Accumulating epidemiological evidence indicates that infection with Porphyromonas gingivalis which is a major periodontal pathogen, causes preterm birth and low birth weight. However, virulence factors of P. gingivalis responsible for preterm birth/low birth weight remain to be elucidated. In this study, using P. gingivalis-infected pregnant mice as an in vivo model, we investigated whether gingipains-cysteine proteinases produced by P. gingivalis-affect preterm birth and low birth weight. We found that intravenous infection of pregnant mice with P...

PURPOSE OF REVIEW: Zika virus' impact on pregnancy became widely known in 2015 with a dramatic increase in the number of babies born with microcephaly in Recife, Brazil. A mosquito-borne virus resulting in congenital anomalies is unique, and Zika's ability to cause neurological defects on a large scale was a grim reminder of the Rubella epidemic in the 1950s. Over the past 2 years, studies have provided insight on how Zika virus (ZIKV) infects cells and causes disease, but much remains unknown about the long-term risks of Zika exposure on infant growth and development...

Hepatitis E virus (HEV) is a member of the genus Orthohepevirus in the family Hepeviridae and the causative agent of hepatitis E in humans. HEV is a major health problem in developing countries, causing mortality rates up to 25% in pregnant women. However, these cases are mainly reported for HEV genotype (gt)1, while gt3 infections are usually associated with subclinical courses of disease. The pathogenic mechanisms of adverse maternal and fetal outcome during pregnancy in HEV-infected pregnant women remain elusive...

It has previously been shown that genital tract infection with Neisseria gonorrhoeae in mice does not induce a state of protective immunity against reinfection but instead suppresses the development of adaptive immune responses against N. gonorrhoeae dependent on transforming growth factor beta (TGF-β) and interleukin 10 (IL-10). Intravaginal administration during gonococcal infection of IL-12 encapsulated in biodegradable microspheres (IL-12/ms) reverses the immunosuppression and promotes the production of gamma interferon (IFN-γ) and of specific antibodies in serum and genital secretions and accelerates clearance of the infection...

Trichomonas vaginalis is a very common, sexually transmitted, infection that may sometimes be asymptomatic or cause vaginitis and urethritis. Recently, it has been associated with adverse obstetric outcomes such as preterm delivery, low birth weight and premature rupture of membranes. Trichomonas vaginalis can be vertically transmitted at birth. It has been found in pharynx and low respiratory tract of neonates with respiratory disease. It has also been involved in some cases of intellectual disability. The recommended treatment is a 2g metronidazole oral single dose, even for asymptomatic patients...

Since the biochemical and molecular mechanisms responsible for ongoing oxidative stress in hyperemesis gravidarum (HEG) patients have not yet been fully elucidated, the aim of this study was to evaluate the possible role of nitric oxide (NO), malondialdehyde (MDA) and other oxidative stress markers in the disease pathophysiology. Moreover, the relation between oxidative stress markers and Helicobacter pylori (H. pylori) infection was also investigated. Women with pregnancies complicated by HEG (n = 33) were compared with pregnant women without HEG (n = 30) and with healthy non-pregnant women (n = 31)...
