The pestivirus bovine viral diarrhea virus (BVDV) is known to bind to the CD46 molecule, which subsequently promotes entry of the virus. Mapping of the BVD-virion-binding site has shown that two peptides, 66EQIV69 and 82GQVLAL87, located on antiparallel beta sheets in the most distal complement control protein module (CCP1), provide the attachment platform. In the present study, we reveal new CD46-encoding transcripts that are predicted to encode CCP1-containing soluble forms. Further, we show that the serum of most adult cattle contains soluble CD46 (sCD46) and that a recombinant soluble isoform neutralizes BVDV infectivity in an in vitro assay...

BACKGROUND:  When treated with the same antibiotic dose, children achieve different 0- to 24-hour area under the concentration-time curves (AUC0-24) because of maturation and between-child physiological variability on drug clearance. Children are also infected by Mycobacterium tuberculosis isolates with different antibiotic minimum inhibitory concentrations (MICs). Thus, each child will achieve different AUC0-24/MIC ratios when treated with the same dose. METHODS:  We used 10 000-subject Monte Carlo experiments to identify the oral doses of linezolid, moxifloxacin, and faropenem that would achieve optimal target exposures associated with optimal efficacy in children with disseminated tuberculosis...

Zika virus (ZIKV) is an arbovirus from the Flaviviridae family. It is usually transmitted by mosquito bite. There have been no reports of severe symptoms caused by ZIKV infection up until the last few years. In October 2013 an outbreak was reported in French Polynesia with severe neurological complications in some affected cases. In November 2015, the Ministry of Health of Brazil attributed the increased number of neonatal microcephaly cases in northeastern Brazil to congenital ZIKV infection. The rapid spread of the virus convinced the World Health Organization to announce ZIKV infection as a "Public Health Emergency of International Concern" in February 2016...

Most published cases of cytomegalovirus infection in pregnancy relate to congenital abnormalities in neonates infected in early pregnancy, while the mother remains asymptomatic. We describe a diagnostically challenging case of an immunosuppressed woman with scleroderma who developed deranged liver function tests attributed to intrahepatic cholestasis of pregnancy and haemolysis, elevated liver enzymes and low platelets syndrome but was ultimately found to have disseminated cytomegalovirus. Cytomegalovirus can present in a myriad of ways...

We report on 3 male neonates with hereditary ADAMTS13 deficiency (Upshaw Schulman syndrome, USS), the inherited form of thrombotic thrombocytopenic purpura (TTP). 2 presented shortly after birth with thrombocytopenia followed by microangiopathic Coombs-negative haemolytic anaemia. Both initially received antibiotic treatment for suspected infection-associated thrombocytopenia. In one patient's brother, the first bout of incipient TTP did not occur before 6 months of age, despite the same genetic defect. ADAMTS13 activity was<5%, compound heterozygous mutations were found in all patients...

Infections with enteroviruses and human parechoviruses are highly prevalent, particularly in neonates, where they may cause substantial morbidity and mortality. Individuals with B-cell-related immunodeficiencies are at risk for severe enteroviral infections, usually a chronic and fatal meningoencephalitis. In transplant recipients and patients with malignancy, enterovirus infections typically involve the respiratory tract, but cases of severe, disseminated infection have been described. The mainstay of diagnosis for enterovirus and human parechovirus infections involves the use of molecular diagnostic techniques...

Hemophagocytic lymphohistiocytosis (HLH) is a hyperinflammatory condition resulting from an uncontrolled and ineffective immune response. Here, we report a case of HLH caused by disseminated herpes simplex virus (HSV)-1 infection. The patient was initially treated with prednisolone and high-dose acyclovir. Although liver enzymes, coagulation abnormalities, and inflammatory markers were remarkably improved, the platelet count remained low. Prednisolone was therefore switched to dexamethasone palmitate. Thereafter, the platelet count normalized...

Hospital water may serve as a reservoir of healthcare-associated pathogens, and contaminated water can lead to outbreaks and severe infections. The clinical features of waterborne outbreaks and infections as well as prevention strategies and control measures are reviewed. The common waterborne pathogens were bacteria, including Legionella and other gram-negative bacteria, and nontuberculous mycobacteria, although fungi and viruses were occasionally described. These pathogens caused a variety of infections, including bacteremia and invasive and disseminated diseases, particularly among immunocompromised hosts and critically ill adults as well as neonates...

Streptococcus agalactiae (Group B Streptococcus or GBS) is a leading cause of invasive infections in neonates whose virulence is dependent on its ability to interact with cells and host components. We here characterized a surface protein with a critical function in GBS pathophysiology. This adhesin, designated PbsP, possesses two Streptococcal Surface Repeat domains, a methionine and lysine-rich region, and a LPXTG cell wall-anchoring motif. PbsP mediates plasminogen (Plg) binding both in vitro and in vivo and we showed that cell surface-bound Plg can be activated into plasmin by tissue plasminogen activator to increase the bacterial extracellular proteolytic activity...

Though the incidence of neonatal infection in term and near-term infants is relatively low, incidence of infection in preterm very low birth weight infants is as high as 20-30% and may result in neurodevelopmental impairment or mortality. Pediatricians should be familiar with recognition and emergency management of life-threatening neonatal infections, such as congenital pneumonia, early onset sepsis, late onset sepsis, bacterial and fungal meningitis, disseminated neonatal herpes simplex virus (HSV), and HSV meningoencephalitis...

Background. Disseminated herpes simplex virus (HSV) in the neonate is associated with significant morbidity and mortality. Current guidelines recommend caesarean in third-trimester maternal primary genital HSV outbreaks to prevent transmission from mother to fetus. In the premature fetus, however, expectant management is often necessary to reduce morbidity of prematurity. The benefit of performing caesarean after 6 hrs of rupture of membranes (ROM) to reduce maternal-fetal transmission is unclear. Case. A female patient with primary genital HSV type 1 outbreak coinciding with preterm, prelabour rupture of membranes (PPROM) at 30 + 3 weeks' gestation...
