BACKGROUND: Perinatally HIV-infected (PHIV) children are at risk for undervaccination and poor vaccine response at four years of age. Childhood vaccine coverage and immune response were compared between PHIV and HIV-exposed uninfected (HEU) children in Latin America and the Caribbean. METHODS: PHIV and HEU children were enrolled prospectively at fifteen sites from 2002-2009. Full vaccination by age four years was defined as: three hepatitis B virus (HBV) vaccine doses; four tetanus toxoid-containing vaccine doses; three doses of Haemophilus influenzae type b (Hib) vaccine by age 12 months or ≥1 dose given after age 12 months; one measles-containing vaccine dose; one rubella-containing vaccine dose...

The presence of bacteria in the lower airways in COPD results in inflammation, further airway structural damage, and might lead to repeated exacerbations. We have previously shown that chronic colonization of Haemophilus influenzae during stable disease is related to increased inflammation, and we now aimed to relate previous findings of bacterial colonization and inflammation to the degree of radiological findings of bronchiectasis and emphysema. Thirty-nine patients with COPD were included in their stable state, and a high-resolution computed tomography of the lung was performed...

Infections due to nontypeable Haemophilus influenzae (NTHi) are important causes of child mortality throughout the world. Given the lack of effective vaccines for these strains and the spread and prevalence of these infections in the world, it is necessary to design novel vaccine candidates against these strains. D and E proteins are conserved membrane-specific lipoproteins among encapsulated and non-encapsulated H. influenza strains, which, according to the exposure surface and conservation degree between both strains, can be considered as vaccine candidates suitable for studies...

Of 73 clinical strains of Haemophilus influenzae isolated from the urethra of men with urogenital infections, we enrolled 6 strains (8.2%) with levofloxacin (LVFX) minimum inhibitory concentrations (MICs) of ≥0.03 μg/ml in this study. All the strains were isolated from non-gonococcal urethritis (NGU). We amplified the quinolone resistance-determining region of the gyrA gene and the analogous region of the parC gene from bacterial DNAs by PCR and sequenced the PCR products. Two strains with a LVFX MIC of 0...

BACKGROUND: During infection, inflammation is partially driven by the release of mediators which facilitate intercellular communication. Amongst these mediators are small membrane vesicles (MVs) that can be released by both host cells and Gram-negative and -positive bacteria. Bacterial membrane vesicles are known to exert immuno-modulatory and -stimulatory actions. Moreover, it has been proposed that host cell-derived vesicles, released during infection, also have immunostimulatory properties...

Haemophilus parasuis infection is of considerable economic importance in the swine industry due to high morbidity and mortality in naive swine populations. Accurate detection and identification of the causative agent are difficult, yet necessary, for disease control. In this study, a simple and rapid method of cross-priming amplification (CPA) with a vertical flow (VF) visualization strip was established to detect H. parasuis. The reaction can specifically identify 15 serovar reference strains and 57 clinically isolated strains of H...

Nontypeable Haemophilus influenzae (NTHi) are Gram-negative pathogens that contribute to a variety of diseases, including acute otitis media and chronic obstructive pulmonary disease. As NTHi have an absolute requirement for heme during aerobic growth, these bacteria have to scavenge heme from their human hosts. These heme sources can range from free heme to heme bound to proteins, such as hemoglobin. To test the impact of heme structural factors on heme acquisition by NTHi, we prepared a series of heme sources that systematically vary in heme exposure and covalent binding of heme to peptide/protein and tested the ability of NTHi to use these sources to support growth...

Although the incidence of ventilator-associated pneumonia (VAP) is very high, there are still many uncertainties about clinical course of VAP among tracheotomized patients. The goal of the present study was to determine the impact of tracheotomy on VAP incidence and etiology, as well as outcome of VAP patients with tracheotomy. The study was conducted in a 15-bed Surgical and Neurosurgical Intensive Care Unit (ICU), Sestre milosrdnice University Hospital Center in Zagreb, Croatia. The study included all patients undergoing only percutaneous tracheotomy during the study period...

PURPOSE: To assess the self-reported vaccination behavior of general practitioners (GPs) when asked whether they would recommend the vaccination of a child presenting with a febrile uncomplicated common cold. METHODS: We performed a cross-sectional survey in 2014 on a national sample of GPs. GPs were randomly assigned to one of eight clinical vignettes, all describing a child presenting with an uncomplicated febrile common cold, but differing by age (4 or 11 months), temperature (38°C or 39°C), and the mother's emotional state (calm or worried)...

Type II toxin-antitoxin (TA) systems play a critical role in the establishment and maintenance of bacterial dormancy. They are composed of a protein toxin and its cognate protein antitoxin. They function to regulate growth during conditions of stress, such as starvation or antibiotic treatment. As cellular proteases degrade the antitoxin, which normally binds and neutralizes the toxin, this frees the toxin to act on its cellular targets and arrest bacterial growth. TA systems are of particular concern in pathogenic organisms such as nontypeable Haemophilus influenzae (NTHi), as dormancy may lead to chronic infections and failure of antibiotic treatment...

BACKGROUND: In cystic fibrosis and bronchiectasis, genetic mannose binding lectin (MBL) deficiency is associated with increased exacerbations and earlier mortality; associations in COPD are less clear. Preclinical data suggest MBL interferes with phagocytosis of Haemophilus influenzae, a key COPD pathogen. We investigated whether MBL deficiency impacted on clinical outcomes or microbiota composition in COPD. METHODS: Patients with COPD (n=1796) underwent MBL genotyping; linkage to health records identified exacerbations, lung function decline and mortality...

Haemophilus parasuis, an important swine pathogen, was recently proven able to invade into endothelial or epithelial cell in vitro. NOD1/2 are specialized NLRs that participate in the recognition of pathogens able to invade intracellularly and therefore, we assessed that the contribution of NOD1/2 to inflammation responses during H. parasuis infection. We observed that H. parasuis infection enhanced NOD2 expression and RIP2 phosphorylation in porcine kidney 15 cells. Our results also showed that knock down of NOD1/2 or RIP2 expression respectively significantly decreased H...

Proton pump inhibitors (PPIs) are the standard therapy for gastroesophageal reflux disease. In adults, PPI treatment is associated with Clostridium difficile infections (CDI). In contrast to adults the microbiome of infants develops from sterility at birth toward an adult-like profile in the first years of life. The effect of PPIs on this developing microbiome has never been studied. The aim of the present study was to determine the effect of oral PPIs on the fecal microbiome in infants with gastroesophageal reflux disease (GERD)...
