Nonencapsulated, nontypeable Hemophilus influenzae (NTHi) remains an important cause of acute otitis and respiratory diseases in children and adults. NTHi bacteria are one of the major causes of respiratory tract infections, including acute otitis media, cystic fibrosis, and community-acquired pneumonia among children, especially in developing countries. The bacteria can also cause chronic diseases such as chronic bronchitis and chronic obstructive pulmonary disease in the lower respiratory tract of adults...

BACKGROUND: The live, attenuated, tetravalent dengue vaccine (CYD-TDV) is licensed in a number of dengue endemic countries for individuals ≥9 years old. Before integration of any vaccine into childhood vaccination schedules, a lack of immune interference and acceptable safety when co-administered with other recommended vaccines should be demonstrated. METHODS: This randomized, multi-center, Phase III trial was conducted in Mexico. Healthy toddlers (n=732) received a booster dose of a licensed pentavalent combination vaccine (diphtheria, tetanus, acellular pertussis, inactivated polio vaccine, and Haemophilus influenzae type b [DTaP-IPV//Hib]) either concomitantly or sequentially with the second dose of CYD-TDV administered as a 3-dose schedule...

Rhomboid proteases are intramembrane enzymes that hydrolyze peptide bonds of transmembrane proteins in the lipid bilayer. They play a variety of roles in key biological events and are linked to several disease states. Over the last decade a great deal of structural and functional knowledge has been generated on this fascinating class of proteases. Both structural and kinetic analyses require milligram amounts of protein, which may be challenging for membrane proteins such as rhomboids. Here, we present a detailed protocol for optimization of expression and purification of three rhomboid proteases from Escherichia coli (ecGlpG), Haemophilus influenzae (hiGlpG), and Providencia stuartii (AarA)...

Haemophilus parasuis is a bacterium from the Pasteurellaceae family that comprises strains of different degree of virulence. Non-virulent strains are considered components of the upper respiratory tract microbiota, while virulent strains can invade systemic organs and cause fibrinous polyserositis (Glässer's disease). Genomic comparison of virulent and non-virulent strains led to the identification of a family of genes differentially associated to virulence, the virulence-associated trimeric autotransporters (vtaA)...

BACKGROUND: ICAM-1 is a major receptor for ~60% of human rhinoviruses, and non-typeable Haemophilus influenzae, two major pathogens in COPD. Increased cell-surface expression of ICAM-1 in response to tobacco smoke exposure has been suggested. We have investigated epithelial ICAM-1 expression in both the large and small airways, and lung parenchyma in smoking-related chronic airflow limitation (CAL) patients. METHODS: We evaluated epithelial ICAM-1 expression in resected lung tissue: 8 smokers with normal spirometry (NLFS); 29 CAL patients (10 small-airway disease; 9 COPD-smokers; 10 COPD ex-smokers); Controls (NC): 15 normal airway/lung tissues...

BACKGROUND: Use of a polysaccharide vaccine challenge to demonstrate immunologic memory after priming with capsular group C meningococcal conjugate vaccines (MenCC) risks induction of immunologic hyporesponsiveness. For this reason, MenCC vaccines are now used as probes of immunologic memory, however, no studies have demonstrated their ability to distinguish primed from unprimed children. METHODS: This study was part of a randomised controlled trial investigating the immunogenicity of a booster dose of the combined Haemophilus influenzae type b and MenC-tetanus toxoid vaccine (Hib-MenC-TT) in infants receiving reduced dose MenCC vaccine priming schedules (one MenC-CRM/MenC-TT or two MenC-CRM vaccine doses) compared with an unprimed group...
