Genetic Detection of Quinolone Resistance in Haemophilus parainfluenzae: Mutations in the Quinolone Resistance-Determining Regions of gyrA and parC by Dennis KS Law, Michelle Shuel, Sadjia Bekal, Elizabeth Bryce, Raymond SW Tsang

“…The quinolone resistance-determining regions of gyrA and parC of both quinolone-sensitive and quinolone-resistant Haemophilus parainfluenzae strains were amplified and sequenced. Similar to Haemophilus influenzae, resistance to quinolones in H parainfluenzae is associated with mutations in the quinolone resistance-determining regions of both gyrA and parC. …”

Nasopharyngeal Bacterial Carriage in the Conjugate Vaccine Era with a Focus on Pneumococci by V. T. Devine, J. M. Jefferies, S. C. Clarke, S. N. Faust

“…It has been shown that, following PCV7 introduction, an eradication of pneumococcal vaccine types has resulted in increases in the abundance of other respiratory pathogens including Haemophilus influenzae and Staphylococcus aureus. These changes are difficult to attribute to PCV7 introduction alone and these studies do not account for further changes due to PCV13 implementation. …”

Alpha-defensins increase NTHi binding but not engulfment by the macrophages enhancing airway inflammation in Alpha-1 antitrypsin deficiency by Jungnam Lee, Naweed Mohammad, Kyudong Han, Kyudong Han, Tammy Flagg-Dowie, Maria Magallon, Mark L. Brantly, Karina A. Serban, Karina A. Serban

“…Despite the antimicrobial activities of α-defensins by direct bacterial killing and by modulation of immune responses, AATD individuals are paradoxically burdened by recurrent exacerbation triggered by bacterial infections, frequently with nontypeable Haemophilus influenzae (NTHi). Previous studies demonstrated that high, rather than low α-defensin level could modulate the local pro-inflammatory milieu of bronchial epithelial cells and macrophages promoting chronic inflammation and lower pathogen phagocytosis. …”
