In contrast to two-dimensional bioluminescence imaging, three dimensional diffuse light imaging tomography with integrated micro-computed tomography (DLIT-μCT) has the potential to realise spatial variations in infection patterns when imaging experimental animals dosed with derivatives of virulent bacteria carrying bioluminescent reporter genes such as the lux operon from the bacterium Photorhabdus luminescens. The method provides an opportunity to precisely localise the bacterial infection sites within the animal and enables the generation of four-dimensional movies of the infection cycle...

Patient-care items can serve as a source or reservoir for healthcare associated pathogens in hospitals. We reviewed healthcare-associated outbreaks from medical equipment and provided infection prevention recommendations. Multiple healthcare-associated outbreaks via a contaminated patient-care item were identified, including infections with multidrug-resistant organisms. The type of patient-care items implicated as a fomite causing healthcare-associated infections (HAI) has changed over time. Patient populations at risk were most commonly critically ill patients in adult and neonatal ICUs...

Sex differences in the immune response and in infectious disease susceptibility have been well described, although the mechanisms underlying these differences remain incompletely understood. We evaluated the frequency of cord blood CD4 T cell subsets in a highly malaria-exposed birth cohort of mother-infant pairs in Uganda by sex. We found that frequencies of cord blood regulatory T cell ([Treg] CD4(+)CD25(+)FoxP3(+)CD127(lo/-)) differed by infant sex, with significantly lower frequencies of Tregs in female than in male neonates (P = ...

Neonatal sepsis is the cause of substantial morbidity and mortality. Precise estimates of neonatal sepsis burden vary by setting. Differing estimates of disease burden have been reported from high-income countries compared with reports from low-income and middle-income countries. The clinical manifestations range from subclinical infection to severe manifestations of focal or systemic disease. The source of the pathogen might be attributed to an in-utero infection, acquisition from maternal flora, or postnatal acquisition from the hospital or community...

The intrauterine environment was long considered sterile. However, several infectious threats are already present during fetal life. This review focuses on the postnatal immunological consequences of prenatal exposure to microorganisms and related inflammatory stimuli. Both the innate and adaptive immune systems of the fetus and neonate are immature, which makes them highly susceptible to infections. There is good evidence that prenatal infections are a primary cause of preterm births. Additionally, the association between antenatal inflammation and adverse neonatal outcomes has been well established...

Zika virus (ZIKV) infection was investigated in adult and fetal STAT2 knock-out (KO) hamsters. Subcutaneous injection of ZIKV of adults resulted in morbidity, mortality, and infection of the uterus, placenta, brain, spinal cord, and testicles, thus providing an opportunity to evaluate congenital ZIKV infection in a second rodent species besides mice. ZIKV-infected cells with morphologies of Sertoli cells and spermatogonia were observed in the testes, which may have implications for sexual transmission and male sterility...

Chicken pox and hand, foot and mouth disease (HFMD) are two major infectious diseases that mainly affect infants and children, causing significant morbidity annually. Varicella-zoster virus (VZV) and enterovirus 71 (EV71), respectively, are the principal epidemic pathogens causing these two diseases. To investigate the possibility of developing a novel combined vaccine to prevent chicken pox and HFMD, we constructed three chimeric virus-like particles (VLPs) (termed HBc-V/1/2, HBc-2/V/1 and HBc-1/2/V) based on the hepatitis B core antigen (HBc) carrier that display epitopes derived from VZV-gE, EV71-VP1, and EV71-VP2 in a varied tandem manner...

Background.: A second-sign prospective restriction of select broad-spectrum antimicrobials was fully implemented in January 2015 as a pediatric antimicrobial stewardship program (ASP) initiative to help ensure the most appropriate empiric use of ceftaroline, cefepime, fidaxomicin, linezolid, and vancomycin (intravenous). The objective of this evaluation is to assess the effectiveness of a forced second-sign process in the electronic medical record as a pediatric ASP strategy. We anticipated that the second-sign process for antibiotics would increase the appropriateness of empiric antibiotic use, as defined by preapproved criteria, clinical pathways, national guidelines, and pediatric-specific infectious diseases reference texts, while not causing significant delay in the initial administration of antibiotic therapy...
