Bacterial colonization of the nasopharynx in paediatric patients with acute respiratory viral symptoms
… those vaccine strains. This will likely alter colonization dynamics, with perhaps serotype replacement or the emergence of vaccine escape mutants. Evidence to date suggests that vaccine serotypes have been partially displaced, and that some non-vaccine strains, such as 19A, are increasingly …

The Colonization Strategies of Nontypeable Haemophilus influenzae - Bacterial Colonization Factors and Vaccine Development
… currently known, and identify novel, bacterial factors involved in the key processes of colonization and pathogenesis, namely adherence to host tissue and evasion of the host innate immunity. We have shown that the NTHi virulence factor Protein E mediates innate immune evasion by …

Bacterial profiles and ex vivo effects of Salmonella Heidelberg on leukocyte function in turkey purebred lines
… an oral Salmonella Heidelberg (SH) challenge on bacterial colonization, and the ex vivo effects of SH on phagocytic and bactericidal leukocyte function in turkeys from six pedigree lines (A-F). Data were analyzed using JMP Pro (SAS) and differences were determined using Student’s t-test following …

Influence of mild therapeutic hypothermia on the inflammatory response after successful resuscitation from cardiac arrest
… by the use of hypothermia (n = 39). The rate of bacterial colonization was significantly higher in hypothermic patients (64.1 vs 12.5%; P b .001). On the contrary, procalcitonin levels were, independent of the use of hypothermia, only significantly elevated in patients with bad neurological …

Development And Application Of Biomimetic Electrospun Nanofibers In Total Joint Replacement
… that promote rapid osseointegration and prevent bacterial colonization, particularly when placed in bone compromised by disease or physiology of the patients. A better understanding of the key factors that influence cell fate decisions at the bone-implant interface is required. Our study is to …

Effect of Advanced Age on the Innate Immune Response to Cutaneous Wound Infection
… contribute to age-associated differences in bacterial colonization and wound closure (iii)To determine if modulation of these age-associated deficits in the early innate response to S. aureus cutaneous wound infection may provide new therapeutic avenues for treating wound infection and …

High throughput RNA interference based screen for the identification of genes implicated in listeria monocytogenes infection
… cells points towards an interplay between bacterial proteins and human host factors. It has become apparent that this interplay is critical for the establishment and spread of infection. Here we describe a high throughput screening approach to assay for potential human host factors involved …

MEMORY TH17 CELLS IN THE LUNG DURING SECONDARY BACTERIAL PNEUMONIA FOLLOWING INFLUENZA A VIRUS INFECTION
Secondary bacterial infection is the primary cause of morbidity and mortality associated with influenza A virus (IAV) infection. Specifically, nontypeable Haemophilus influenzae (NTHi) and Streptococcus pneumoniae (Sp) are the most common cause of lethal secondary bacterial pneumonia in IAV …

Construction, characterization, and evaluation of CLH001 as a vaccine candidate against respiratory glanders
… resulted in 100% survival with no detectable colonization or abnormal histopathology in the lungs, liver or spleen of vaccinated mice. BALB/c mice immunized i.n. with 1.5x105 CFU of CLH001 in a prime/boost regimen showed full protection post-challenge with 1.5x104 CFU of B. mallei lux wt …

Biofilm-derived Small Molecules Released from Mixed-species Cultures of Fusobacterium necrophorum and Porphyromonas levii Inhibit Bovine Neutrophil Functional Responses
Bacterial biofilms are surface adhered communities of microorganisms encased in a protective polysaccharide layer. These resilient structures present significant challenges for effective host immune cell clearance or clinical interventions, frequently resulting in recurrent infections in cattle, …

Investigating bacterial adhesion proteins as tools for controlling bacteria-surface interactions
… that initiate target binding and surface colonization by bacteria on the path to infection and biofilm formation. A deeper understanding of the interactions between adhesins and their ligands may lead to the development of strategies for controlling infection and biofilm formation. Using …

Plastics and Microplastics as Vectors for Bacteria and Human Pathogens
… and can thus provide a novel habitat for colonization by bacterial communities. The full spectrum of relationships between plastics and bacteria, however, is little understood. The objective of this study was to examine marine plastic pollution as a substrate for bacteria, with particular …

Rhizosphere Bacteria and Phytostabilization Success: The Association Between Bacteria, Plant Establishment and Metal(loid) Immobilization in Metalliferous Mine Tailings
… The aims of this dissertation are to focus on bacterial communities associated with the roots of buffalo grass used in the phytostabilization of pyritic metalliferous mine tailings to: i) characterize bacterial diversity and communities of rhizosphere and bulk substrate, ii) delineate …

Effect of soil structure on temporal and spatial dynamics of bacteria
… connectivity and soil-pore interface influenced bacterial distribution only at the macroscale. The method developed was applied to investigate the effect of soil pore characteristics on the extent of spread of bacteria introduced locally towards a C source in soil. Soil-pore interface influenced …

Aderência in vitro de bactérias bucais a diferentes tipos de piercings linguais
… tongue piercings, presenting differences in the bacterial colonization pattern on distinct materials of tongue piercings. The aim was to assess the in vitro adherence of E. corrodens (ATCC 23834) and S. oralis (ATCC 10557) to the surface of tongue piercings made of surgical steel, titanium, …

Characterization of the Helicobacter pylori vacuolating cytotoxin mediated induction of mitochondrial cell death mechanism
… deregulation of mitochondrial dynamics promotes bacterial colonization by generating a novel class of dysfunctional host cells that are energetically crippled, and unable to respond appropriately to infection with H. pylori at the epithelial barrier.
